How to Undervolt a GPU: 12 Steps, 45 Min [2026]

Every watt a graphics card pulls from the wall shows up somewhere: on the power bill, on the case fan curve, or on the thermal throttle that quietly shaves clock speed once the die gets too hot. Undervolting is the one tuning trick that attacks all three at once without asking you to spend a single dollar. Instead of pushing more voltage through the chip to chase a higher clock, you feed it less voltage at the clocks it already reaches, and in most cases the card runs cooler, quieter, and just as fast. This guide walks through exactly how to undervolt a GPU on Nvidia, AMD, and Intel Arc hardware, using MSI Afterburner, AMD Software: Adrenalin Edition, and the handful of Arc-specific workarounds that current Intel drivers still do not officially support.

By the end you will have a stable, saved voltage/frequency curve running on your card, verified through a real stress test rather than a guess. We cover 12 steps in total, and the whole process, including a proper stability test, takes about 45 minutes for most people. Nothing here requires opening the case or touching the BIOS. It all happens inside software your GPU vendor already ships.

Timing matters more in 2026 than it did a couple of generations back. Nvidia’s RTX 5090 carries a 575W board power rating, and even the mid-range RTX 5070 Ti is rated at 300W. AMD’s RX 9070 XT sits at roughly 304W. Cards draw more than they used to, cases run hotter, and fan noise has become a bigger complaint among buyers who used to only care about frame rates. Undervolting does not fix a bad case airflow setup, but it takes real heat and real noise off the table before you start blaming your cooler.

What GPU Undervolting Actually Does

As tech journalist Jon Martindale explains at PCWorld, “undervolting refers to the act of decreasing the voltage supplied to your GPU.” That is the entire concept in one sentence, but the reason it works is worth unpacking. Every modern GPU ships with a voltage/frequency curve baked in at the factory, a table that maps each clock speed to a voltage the manufacturer considers safe across a wide range of silicon quality, cooling setups, and ambient temperatures. Because that curve has to work for the worst chip off the production line in the hottest room, it is padded with headroom that a better-than-average sample simply does not need.

Undervolting rewrites part of that curve. You tell the card to hit the same clock speed at a lower voltage than the factory default, and if your specific chip can sustain that clock at the reduced voltage, you get identical performance for less power and less heat. Push it too far and the card either crashes, shows corrupted textures, or the driver resets itself, none of which causes lasting damage since the safeguard just kicks the voltage back up automatically. Martindale frames the goal clearly: “the goal is to sustain performance levels that are relatively close to factory settings while enhancing efficiency.” You are not trying to slow the card down. You are trying to find the lowest voltage that still gets you the clocks you already had.

Power draw and heat do not scale in a straight line with voltage. They scale closer to the square of it, so a modest voltage cut delivers an outsized drop in watts and degrees. That relationship is why undervolting has a reputation for punching above its weight compared with other tuning methods, and why it is popular even among people who have no interest in overclocking at all.

Undervolting vs Overclocking: Why They Are Not Opposites

People new to GPU tuning often assume undervolting and overclocking sit on opposite ends of the same dial. They do not. Overclocking raises clock speed, usually by adding voltage or at least holding it steady while pushing frequency higher, and it is covered in depth in our GPU overclocking guide if raw performance is what you are after. Undervolting instead holds clock speed roughly where it already sits and removes excess voltage the chip was not using. Some tuners combine the two into what the community calls an undervolt-overclock, where you drop voltage first and then nudge the core clock upward at that new, lower voltage point, often landing on higher sustained clocks than stock while still running cooler than stock. That combined approach is exactly what you will build in the step-by-step section below.

The practical distinction that matters for choosing between them is your goal. If you want the highest possible frame rate and do not mind extra fan noise and a hotter room, a straight overclock gets you there faster. If you want a quieter PC, lower temperatures, and a smaller power bill with performance that stays close to stock, undervolting is the better starting point, and it is also lower risk since you are reducing stress on the silicon rather than adding it.

Prerequisites: What You Need Before You Undervolt a GPU

You do not need exotic hardware for this. Almost any discrete GPU from the last several generations supports voltage curve tuning through vendor or third-party software. What you do need is the right monitoring and tuning tool for your GPU brand, a way to stress-test the result, and roughly 45 minutes of uninterrupted time so you are not rushing the stability testing.

Which GPUs Support Voltage Curve Editing

Nvidia and AMD cards from the last few generations all expose voltage control through their respective tools. Intel’s Arc lineup is the outlier, and we cover exactly what that means in its own section further down. The table below lists current-generation cards from all three vendors along with their rated board power, which matters because higher-power cards generally have more thermal and power-draw headroom to claw back through undervolting.

GPU	Rated Power (TDP/TBP)	Voltage Curve Editing	Primary Tool
Nvidia RTX 5090	575W	Yes	MSI Afterburner
Nvidia RTX 5080	360W	Yes	MSI Afterburner
Nvidia RTX 5070 Ti	300W	Yes	MSI Afterburner
Nvidia RTX 5070	250W	Yes	MSI Afterburner
AMD RX 9070 XT	~304W	Yes	AMD Software: Adrenalin Edition
AMD RX 9070	~220W	Yes	AMD Software: Adrenalin Edition
AMD RX 9060 XT	~150-160W	Yes	AMD Software: Adrenalin Edition
Intel Arc B580	190W	Partial (no native undervolt)	Arc OC Tool (third-party)
Intel Arc B570	150W	Partial (no native undervolt)	Arc OC Tool (third-party)

If you are still choosing between cards rather than tuning one you already own, the power gap between something like the RX 9070 and the RTX 5070 is worth factoring in, since the higher-draw card usually has more room to give back through undervolting.

Tools You Will Use

Download these before you start so you are not hunting for installers mid-session. All version numbers below reflect what was current in mid-2026.

Tool	Current Version	Use
MSI Afterburner	4.6.6 stable (4.6.7 beta available)	Nvidia and most AMD voltage/frequency curve editing
AMD Software: Adrenalin Edition	26.6.4	Native AMD tuning tab, alternative to Afterburner on Radeon cards
GPU-Z	2.70.0	Read-only sensor confirmation and driver/BIOS info
HWiNFO	v8.50	Detailed sensor logging during stress tests
FurMark / 3DMark	Current release	Synthetic stress testing for stability and thermal load

You do not strictly need all five at once. Afterburner alone covers both the tuning and the on-screen monitoring for Nvidia cards, and Nvidia’s own Nvidia App has picked up some basic tuning features too, though it is not yet a full replacement for Afterburner’s curve editor. GPU-Z and HWiNFO are there for a second opinion when you want to confirm a reading rather than trust a single tool.

Checking Your GPU’s Current Baseline

Before changing anything, confirm what driver you are running and grab a baseline reading. An outdated driver can behave unpredictably under a modified voltage curve, so update first if you have not done so recently. Check your installed version from PowerShell:

Get-CimInstance Win32_VideoController | Select-Object Name, DriverVersion, DriverDate

On Nvidia cards, you can also pull a live snapshot of clocks, power draw, and temperature directly from the command line, which is a fast way to record your “before” numbers without opening a monitoring overlay:

nvidia-smi --query-gpu=name,temperature.gpu,power.draw,clocks.gr,clocks.mem --format=csv

A typical result looks something like this on an idle-to-light-load RTX 5070 Ti:

name, temperature.gpu, power.draw [W], clocks.current.graphics [MHz], clocks.current.memory [MHz]
NVIDIA GeForce RTX 5070 Ti, 44, 62.30 W, 405 MHz, 405 MHz

Write these numbers down, or better, run the same command again after a stress test later so you have real load figures too, not just idle ones. The idle numbers matter less than what happens once the card is actually working, which is the comparison you will lean on later in this guide.

How Much Can You Actually Gain From Undervolting?

Results depend heavily on your specific chip, so treat any number here as a range rather than a promise. Across the enthusiast tuning community, the commonly reported outcome for a reasonably aggressive but stable undervolt sits around 10 to 25 percent lower power draw at the same clock speed, paired with roughly 5 to 20 degrees Celsius lower load temperatures. Cards that ship with a conservative factory curve, which tends to describe higher-end parts built to a strict power ceiling, often have more room to give back than a card that was already tuned tight from the factory.

None of that is guaranteed. Silicon quality varies chip to chip even within the same model number, a phenomenon the overclocking community has nicknamed the silicon lottery. Two RTX 5070 Ti cards bought on the same day can tolerate meaningfully different voltage offsets before either one crashes. That is normal, and it is exactly why this guide walks you through testing your own card rather than just handing you a fixed number to type in.

What you should not expect is a free performance increase from undervolting alone. The point is to hold performance steady while cutting power and heat. If your specific card also happens to sustain a slightly higher boost clock once it is running cooler and pulling less power, thank the reduced thermal throttling, not some hidden reserve of extra speed the undervolt unlocked. That said, it is a common enough side effect that it is worth checking for once your curve is stable.

How to Undervolt a GPU: Step-by-Step

The 12 steps below are written primarily around MSI Afterburner on an Nvidia card, since it is the most widely used tool and works across both Nvidia and most Radeon cards. The AMD-native and Intel Arc sections further down adapt the same underlying process to Adrenalin and Arc’s more limited tooling. Budget about 45 minutes total, most of it spent on the stress-testing loop rather than the actual settings.

Step 1: Install MSI Afterburner and RivaTuner Statistics Server

Download MSI Afterburner only from MSI’s official site or its mirror at Guru3D, since MSI has repeatedly warned that other download sites bundle unrelated software with the installer. During setup, accept the bundled installation of RivaTuner Statistics Server (RTSS) when prompted. RTSS handles the on-screen overlay you will use later to watch clocks and temperatures while gaming, and Afterburner will not display an in-game overlay without it.

Step 2: Run a Baseline Stress Test

Before touching any sliders, run 10 to 15 minutes of FurMark or 3DMark’s Time Spy Stress Test at your card’s stock settings. Watch temperature, power draw, and clock speed through Afterburner’s on-screen display, and note the numbers once they stabilize. This is the baseline you will compare every later change against, and skipping it is the single biggest reason people misjudge whether an undervolt actually helped.

Step 3: Open the Voltage/Frequency Curve Editor

In Afterburner’s main window, press Ctrl+F to open the curve editor. You will see a graph plotting core clock against voltage, essentially a visual map of your GPU’s factory-programmed behavior at every voltage step it is capable of running. This curve is what you are about to reshape.

Step 4: Pick Your Target Voltage Point

Find the point on the curve that corresponds to a voltage roughly 50 to 100 millivolts below your card’s default boost voltage, a conservative first-pass range that rarely causes instability on a first attempt. Click that point directly on the graph. This becomes your new maximum voltage, and Afterburner will not let the card exceed it once applied.

Step 5: Raise the Core Clock at That Voltage Point

Drag the point you selected upward until its corresponding clock speed matches, or ideally slightly exceeds, the boost clock you recorded during your baseline stress test. You are telling the card, in effect, to hit that same clock speed while never asking for more voltage than the point you just set.

Step 6: Flatten the Curve Above Your Target Point

Select every point on the curve to the right of the one you just adjusted, then drag them down to match the same clock speed and voltage as your target point. This creates a flat line across the top of the curve, which prevents the card from ever requesting a higher voltage than your new limit, even under a heavier load than your stress test covered.

Step 7: Apply and Save the Profile

Click the checkmark icon to apply your changes, then click the save icon and choose one of Afterburner’s five profile slots. Saving to a numbered profile means you can revert instantly by loading a different slot, rather than rebuilding the curve from scratch if something goes wrong later.

Step 8: Re-Run the Stress Test

Repeat the same FurMark or 3DMark stress test from Step 2 for at least 15 to 20 minutes. Watch for driver crashes, artifacting (odd flickering textures or colored specks on screen), or a hard system freeze. Any of those three means your current voltage point is too aggressive for this specific chip.

Step 9: Fine-Tune in Small Increments

If Step 8 crashed or artifacted, move your target voltage point back up slightly and retest. PC hardware YouTuber JayzTwoCents describes the approach plainly in his own undervolting walkthrough: “I recommend moving in 25mV increments until you find a crash, then go back to the last stable setting,” a method you can watch demonstrated in his GPU undervolting guide on YouTube. Working in small steps takes longer than guessing at a big offset up front, but it is the difference between a curve that is stable for a 15-minute test and one that is stable for a six-hour gaming session three weeks from now.

Step 10: Validate in Real Games, Not Just Synthetic Benchmarks

A synthetic stress test loads the GPU differently than an actual game does, and some unstable curves only reveal themselves once you switch scenes, load a new area, or hit a particularly demanding frame in an open-world title. Play two or three different games you actually own for 20 to 30 minutes each, ideally titles with different rendering demands, before calling your curve finished. A curve that survives FurMark but crashes 40 minutes into a game session is not actually stable.

Step 11: Set Afterburner to Launch and Apply on Startup

Your saved profile only helps you if it is actually active every time you turn on your PC. In Afterburner’s settings, enable “Start with Windows” and “Start minimized,” and confirm your saved profile is set to apply automatically on launch. If you want Afterburner to open minimized to the system tray without cluttering your taskbar on boot, its shortcut supports a documented -m command-line switch for exactly that.

Step 12: Add a Power Limit Adjustment (Optional)

Once your voltage curve is stable, you can also lower the power limit slider a few percent below 100. This caps total board power directly, on top of the voltage savings you already banked, and is useful if you are chasing the lowest possible noise floor rather than maximum clocks. Test stability again after any power limit change the same way you did in Steps 8 through 10, since it interacts with your curve rather than replacing it.

Undervolting an AMD Radeon GPU With Adrenalin

AMD Software: Adrenalin Edition, currently at version 26.6.4, includes native tuning tools that cover the same ground as Afterburner without needing a separate install. Open Adrenalin, go to Performance, then Tuning, and switch from Automatic to Manual mode (sometimes labeled Undervolt or Advanced Control depending on your driver revision). From there, you get sliders for GPU voltage, core frequency, and power limit, alongside a real-time monitoring pane so you do not need a second tool running to watch the effect of each change.

The process mirrors the Afterburner steps above almost exactly. Drop the voltage slider by roughly 50 to 100 millivolts to start, confirm the frequency slider still targets your card’s stock boost clock or higher, apply the change, and run the same FurMark or 3DMark stress test used in Step 8. AMD’s tuning tab also exposes a memory clock and memory voltage offset separately from the core, which is worth leaving alone on your first pass since core voltage is where almost all of the power and heat savings come from.

Confirm which Radeon driver you are running before you start, the same way you would check an Nvidia driver in the baseline step above:

Get-CimInstance Win32_VideoController | Where-Object {$_.Name -like "*Radeon*"} | Select-Object Name, DriverVersion

One Adrenalin-specific detail worth knowing: AMD’s driver occasionally resets custom tuning profiles after a major driver update, more often than Afterburner resets Nvidia profiles after an Nvidia driver update. If you update your Radeon driver and notice your fans spinning up louder than usual or temperatures creeping back toward stock, check the Tuning tab first before assuming something is wrong with the card itself.

Undervolting an Intel Arc GPU: What Is Different

Intel Arc is the one platform where this guide’s process does not directly apply, and it is worth being upfront about that rather than glossing over it. According to Intel’s own support documentation, Arc Control (and its successor, Intel Graphics Software) only allows a positive voltage offset for overclocking on B-series cards like the Arc B580 and Arc B570. There is currently no official, driver-level way to reduce voltage below the factory curve on Arc hardware.

That has not stopped the enthusiast community from building workarounds. Third-party utilities such as the community-built Arc OC Tool can lock voltage and frequency at specific points beyond what Intel’s own software exposes, and Linux users have an additional option in LACT (Linux GPU Configuration and Monitoring Tool), which provides voltage control through a graphical interface Intel does not officially support on Windows. Both routes work outside Intel’s supported feature set, so treat them as advanced, higher-risk options rather than a direct Arc equivalent of the Afterburner or Adrenalin workflow above.

If you own an Arc B580 or B570 and mainly want lower fan noise rather than a true undervolt, lowering the power limit through Arc Control’s supported controls gets you part of the way there without stepping outside Intel’s official tools.

6 Common Pitfalls When Undervolting a GPU

Most undervolting complaints trace back to one of these six mistakes rather than a genuine tool or hardware failure.

• Jumping straight to an aggressive offset. Dropping 150mV on your first attempt skips the incremental process that reveals exactly where your specific chip’s limit sits, and makes it harder to tell which change caused an eventual crash.
• Testing only with a synthetic benchmark. FurMark and 3DMark load the GPU differently than real games do. A curve that survives ten minutes of FurMark can still crash in a game with different rendering patterns, which is exactly why Step 10 above exists.
• Forgetting to flatten the curve above your target point. If you only move a single point instead of flattening everything to its right, the card can still request higher voltage under specific loads, undermining the stability and efficiency gains you were trying to lock in.
• Not saving the profile, or saving it without enabling auto-apply on startup. A perfectly tuned curve does nothing for you if it resets to factory defaults every time you restart your PC, which is the default behavior unless you explicitly enable Afterburner or Adrenalin’s startup options.
• Confusing a crash with hardware damage. An unstable undervolt causes a driver reset, an artifact, or a system freeze, not permanent damage. It can feel alarming the first time it happens, but the fix is simply backing off the voltage point, not a hardware concern.
• Assuming someone else’s numbers will work identically on your card. A voltage offset that runs rock solid on a forum post or YouTube video reflects that specific reviewer’s silicon sample. Use other people’s numbers as a starting reference point, not a setting to copy blindly.

Troubleshooting: GPU Undervolting Problems and Fixes

Work through this list if something is not behaving as expected after applying a voltage curve.

• Driver crashes or the screen goes black during a stress test. Your current voltage point is too low for the clock speed you set. Roll back to your last saved stable profile and increase the voltage offset in smaller increments.
• Game crashes to desktop but stress tests pass fine. Some games load the GPU in ways synthetic benchmarks do not replicate. Back off your offset slightly and re-test in the specific game that crashed rather than assuming your curve is broken outright.
• Curve editor changes will not apply. Confirm Afterburner or Adrenalin is running with administrator privileges. Voltage control frequently requires elevated permissions that a standard user account does not have by default.
• Settings reset after a driver update. This is expected behavior on both Nvidia and AMD drivers, more common with AMD. Reopen your tuning software and reapply your saved profile after any driver update.
• Fan curve or RGB lighting stopped responding after installing Afterburner. This usually points to a conflict with another monitoring utility running at the same time, commonly a motherboard vendor’s own software. Close duplicate monitoring tools and restart Afterburner.
• Temperatures did not drop even though the voltage curve is confirmed active. Check that you actually flattened the curve above your target point from Step 6. A single moved point without flattening the rest of the curve leaves the card free to spike voltage under specific loads.
• Artifacting (flickering textures, colored specks) appears only after 30-plus minutes of play. This points to marginal stability rather than an obviously broken curve. Increase your voltage offset slightly, since some instability only surfaces once the card has been under sustained thermal load for a while.
• GPU-Z or HWiNFO show a different voltage than what you set in Afterburner. This is usually normal. The card still applies its own dynamic boost behavior within the ceiling you set, so the displayed voltage reflects real-time boost behavior, not a fixed value.

Laptop GPU Undervolting: What Is Different

Laptop GPUs complicate this process in ways desktop cards do not deal with. Many laptop manufacturers lock voltage control at the firmware or vBIOS level, which means Afterburner’s curve editor may open normally but simply refuse to apply any change you make, showing no error beyond the setting silently reverting. Whether your specific laptop allows GPU voltage control depends entirely on what the OEM chose to expose, not on the GPU model itself.

If your laptop does allow it, the same Afterburner or Adrenalin process above applies without modification. If it does not, you still have options. Power limit adjustments are typically exposed even when voltage is locked, and they deliver a meaningful chunk of the same thermal and noise benefit. CPU-side undervolting on laptops is commonly handled through a separate tool called ThrottleStop rather than Afterburner, since it targets the processor’s voltage regulation rather than the graphics chip, and the two are worth treating as separate projects rather than one combined tuning pass.

Advanced Tips: Getting More Out of Your Undervolt

Build a per-game profile if your library has very different demands. Afterburner supports multiple saved profiles, so a competitive shooter that runs at a locked, moderate frame rate and a demanding open-world title with unlocked frame rates can each get their own curve rather than sharing one compromise setting.

Log your sensors during long sessions instead of eyeballing an overlay. HWiNFO can write a continuous log to a CSV file, which is far more useful than a glance at an on-screen overlay if you are trying to catch an intermittent stability issue that only shows up after an hour of play. On Nvidia cards, the same result comes from looping the query command from earlier at a fixed interval:

nvidia-smi --query-gpu=temperature.gpu,power.draw,clocks.gr --format=csv -l 5 -f gpu-log.csv

That command samples temperature, power draw, and core clock every 5 seconds and writes the results to a file you can review afterward, which is a much better record than trying to remember what the overlay showed twenty minutes into a session.

Pair it with other free tuning wins in the same sitting. If you have not already enabled your memory’s rated speed, our guide to enabling XMP or EXPO for RAM covers a similarly quick, no-cost setting worth handling the same day. The same goes for Resizable BAR, a separate free performance setting that has nothing to do with voltage but is worth confirming is active while you are already deep in tuning mode.

Re-test after any driver update, not just GPU swaps. Vendor drivers occasionally change default boost behavior in ways that interact with an existing custom curve. A quick 10-minute stress test after major driver updates catches this before it becomes a mystery crash three weeks later.

Do not neglect case airflow just because the GPU runs cooler. An undervolt reduces the heat your GPU produces, but it does not replace proper intake and exhaust airflow if your case was thermally constrained to begin with. If you are assembling a new system from scratch, our gaming PC build guide covers case airflow fundamentals that make any GPU, undervolted or not, run cooler.

A Complete Walkthrough: Before-and-After on a 2026 Build

To show how the full process fits together, here is what it looks like end to end on an RTX 5070 Ti, a 300W card with enough factory headroom to make a good demonstration case. Treat the specific numbers as one illustrative example rather than a guarantee for your own card, since silicon variance means your results will differ by some margin either way.

Before any changes, a 15-minute FurMark run settles at a boost clock around 2,610MHz, a power draw hovering near the card’s 300W limit, and a load temperature in the mid-70s Celsius, loud enough that the case fans are clearly audible from across the room. Opening Afterburner’s curve editor and selecting the point roughly 75mV below the default boost voltage, then dragging it up to match that same 2,610MHz clock and flattening every point to its right, takes about five minutes including a couple of false starts finding the right point to click.

The first stress test at that setting runs clean for the full 15 minutes with no artifacts or crashes, so there is room to push slightly further. Backing the voltage point down another 25mV per JayzTwoCents’ incremental approach cited earlier, reapplying, and running FurMark again for 20 minutes this time surfaces a single brief artifact around the 18-minute mark, the signal to back off. Returning to the previous stable point and confirming it survives a fresh 20-minute run, followed by 30 minutes each across two different games, is where the curve gets locked in and saved to a profile with startup auto-apply enabled.

A final nvidia-smi snapshot taken mid-stress-test confirms the tuned card is holding its target clock at the lower voltage ceiling, with power draw sitting well under the card’s 300W limit:

name, temperature.gpu, power.draw [W], clocks.current.graphics [MHz], clocks.current.memory [MHz]
NVIDIA GeForce RTX 5070 Ti, 61, 241.85 W, 2625 MHz, 1313 MHz

Metric	Stock Settings	After Stable Undervolt
Boost clock under load	~2,610MHz	~2,610-2,650MHz
Power draw under load	~300W (at limit)	~230-255W (roughly 15-23% lower)
Load temperature	Mid-70s °C	High-50s to low-60s °C
Perceived fan noise	Clearly audible across the room	Noticeably quieter at the same ambient temperature

Total time for this specific walkthrough, from installing Afterburner to a fully validated, saved profile, ran close to 45 minutes, which lines up with the estimate at the top of this guide. Most of that time went into the repeated stress tests rather than the curve editor itself, and that ratio is normal. The tuning is fast. The proving it is stable is the part worth not rushing.

Is Undervolting Safe? Warranty, Risk, and What Can Go Wrong

Undervolting carries less risk than overclocking, not more, since you are reducing the voltage the chip has to handle rather than pushing beyond factory limits. The realistic worst case if you set an offset too aggressively is a driver crash, a brief artifact, or a system freeze that requires a restart, all of which resolve the moment you back off the voltage point or reload a previous saved profile. None of these outcomes causes lasting damage to the GPU.

Neither Nvidia nor AMD publish a blanket statement that undervolting itself voids a warranty, and the practical framing worth using is that a software voltage adjustment is a very different category of modification than physically altering a card, for instance removing the cooler or bypassing the power connector. If you are shopping for a new card rather than tuning one you already own, the physical power connector is worth getting right regardless of whether you plan to tune it, and our 12VHPWR cable installation guide covers that process safely for any RTX 40-series or RTX 50-series card.

The one caution worth repeating: never combine undervolting with disabling any of your GPU’s built-in thermal or power protections. Those safeguards are what make undervolting reversible and low-risk in the first place, and they should stay active no matter how confident you are in your curve.

Frequently Asked Questions

Does undervolting reduce FPS?
Done correctly, no. The goal is to hold your existing boost clock steady at a lower voltage, so frame rates should stay roughly where they were, and some cards even sustain slightly higher clocks once running cooler and pulling less power.

Can undervolting damage my GPU?
No. Reducing voltage puts less stress on the silicon than stock operation, not more. An unstable curve causes a crash or artifact that resolves once you back off the setting, not permanent hardware damage.

How much lower will my temperatures actually get?
Commonly reported results across the tuning community land around 5 to 20 degrees Celsius lower under load, though your specific result depends on your chip, cooler, and case airflow. Treat any number, including the ones in this guide, as a range rather than a guarantee.

Is MSI Afterburner safe to use on a non-MSI graphics card?
Yes. Afterburner works across Nvidia cards from any board partner and most AMD cards, despite carrying the MSI name. It is one of the most widely used GPU tuning tools precisely because it is not locked to MSI-branded hardware.

Why can’t I undervolt my Intel Arc GPU the same way?
Intel’s own Arc Control and Intel Graphics Software currently only expose a positive voltage offset for overclocking, not a reduction below stock. Third-party tools exist for advanced users willing to step outside Intel’s officially supported feature set.

Do I need to redo this after every GPU driver update?
Not always, but check after major updates regardless. AMD’s driver resets custom tuning profiles somewhat more often than Nvidia’s does, and either vendor can occasionally change default boost behavior in a way that interacts with an existing curve.

Should I undervolt the memory too, or just the core?
Start with the core alone. Core voltage delivers the large majority of the power and heat savings, and memory undervolting adds complexity and instability risk for a comparatively small additional gain, better suited to a second pass once your core curve is already confirmed stable.

What is the difference between undervolting and lowering the power limit slider?
A power limit adjustment caps total board wattage directly and can reduce performance if the card would otherwise need more power to sustain its clocks. Undervolting targets the voltage-to-clock relationship instead, aiming to preserve performance while cutting the power and heat needed to reach it. The two can be combined, as covered in Step 12 above.
