You can often improve a GPU’s sustained frame rate, benchmark score, efficiency, temperature, or noise without replacing it. The reliable method is empirical: establish a repeatable baseline, change one supported control at a time, and keep the last stable profile. A clock increase may raise performance, while an undervolt may deliver similar clocks with less power and heat; neither produces a guaranteed percentage gain on every card.
What “more performance” can mean
Before touching a slider, choose the result you actually want. A higher peak clock is only useful if it produces a higher sustained frame rate or score in the applications you use. A cooler, quieter card that maintains its clock for a longer session can be a better outcome than a short benchmark spike.
- Sustained performance: higher average or low-percentile frame rates, or a higher repeatable benchmark score.
- Efficiency: similar performance at lower voltage and power, leaving more thermal and acoustic headroom.
- Thermals: lower GPU temperature or less thermal throttling during a long workload.
- Noise: lower fan speed and acoustic output while maintaining acceptable temperatures.
- Consistency: fewer clock drops, driver resets, stutters, or application crashes.
These goals can conflict. More voltage and a higher power limit can help a core overclock but usually increase heat and fan noise. A quieter fan curve can raise temperature. Undervolting can improve performance per watt, but an aggressive setting can cause instability. Decide which metric matters most before comparing results.

Every tuning decision should be compared with a stock result from the same system. Run the same game sequence or benchmark at the same resolution, graphics settings, frame-rate cap, and duration. Record the result and the conditions under which it was obtained.

Record the measurements that explain the result
- Average frame rate and, where available, a low-percentile frame rate or benchmark score.
- GPU utilization percentage. Low utilization can indicate a CPU, frame-cap, synchronization, or game-engine limit rather than a weak GPU setting.
- Core clock and memory clock during the run, not merely the advertised boost figure.
- GPU temperature, hotspot or junction temperature when the software exposes it, and whether the temperature rises steadily over time.
- Board power or GPU power, plus fan speed or fan percentage.
- Driver resets, visual artifacts, hangs, crashes, or sudden drops in clock speed.
MSI’s monitoring guidance emphasizes recording GPU metrics and comparing test results. A monitoring overlay or logging panel in a utility such as MSI Afterburner can make this practical, while the vendor’s own software may expose the same information. Keep the overlay out of screenshots used for visual comparison if it changes frame pacing.
Make the test repeatable
- Choose one representative game scene, built-in benchmark, or application workload. Use a repeatable route or run sequence rather than an arbitrary moment in gameplay.
- Set resolution, quality preset, ray-tracing options, upscaling mode, frame cap, and synchronization identically for every run.
- Allow the card to reach its normal operating temperature before recording the result. A cold first run is not comparable with a heat-soaked tenth run.
- Run the baseline more than once. If scores vary materially, investigate background activity, shader compilation, streaming, or an inconsistent scene before tuning.
- Save the baseline numbers and a screenshot or log. Keep a stock/default profile available so you can return to it immediately.
Check for non-tuning bottlenecks first
Tuning cannot fix a blocked airflow path, a CPU-limited workload, or an external power restriction. Inspect the obvious possibilities while the card is still at default settings.
Airflow, dust, and temperature limits
Verify that intake and exhaust vents are unobstructed and that dust is not restricting the heatsink or case filters. Compare temperature and clock behavior at the beginning and end of a long run. A card that starts fast and then drops its clock as it heats may benefit more from airflow work than from a higher clock target.
A 120 mm case fan is relevant only if measurements show a case-airflow problem and the chassis supports that size and mounting position. It is not a required GPU upgrade and cannot guarantee a performance increase. Confirm the fan’s physical clearance, connector, and intended airflow direction before buying anything.
CPU, frame caps, and background load
If GPU utilization remains well below full load while one or more CPU threads are busy, raising the GPU clock may not change frame rate. Temporarily check the game’s frame cap and synchronization settings, and close unnecessary background workloads. Treat these as diagnostic checks rather than assumptions about the cause.

Power and platform restrictions
A laptop may impose a shared CPU/GPU power budget, a fixed thermal policy, or manufacturer restrictions on fan and voltage controls. A desktop card can also be constrained by its power limit, connector configuration, or case cooling. Identify the exact GPU model, driver, and desktop or laptop form before choosing controls.
Use supported vendor controls
Prefer the GPU maker’s supported controls when they are available for your model. On supported Radeon cards, AMD Software: Adrenalin Edition can provide presets, GPU and VRAM tuning, power-limit controls, fan settings, undervolting, metrics, stress testing, saved profiles, and reset functions. The available controls differ by GPU generation and system.
Recommended Free Tools
MSI Afterburner can provide monitoring and tuning functions on compatible cards, including saved profiles and restoring defaults. Its visible controls and the controls exposed by the GPU driver are not identical on every model. If a slider is missing or locked, do not work around the restriction with an unrelated utility; treat the limitation as part of that system’s supported configuration.
Keep a stock profile
Save or note a default profile before making changes. AMD documents saving and loading tuning profiles and resetting tuning; MSI documents saved profiles and restoring defaults. Name profiles by purpose, such as “stock,” “quiet,” or “validated,” and do not overwrite the last known-good profile during an experiment.
Choose one tuning strategy
Change one control at a time so you can attribute a result and undo a problem. Do not apply universal slider values to an unspecified GPU: silicon quality, cooler design, memory type, firmware, driver, workload, and laptop policy all affect the safe operating range.

Modest core overclocking
A core-clock adjustment attempts to increase GPU performance. Start with a small increment, apply it, and run a short stability check followed by the repeatable benchmark. If the result improves without errors, continue in small steps. Stop when the score stops improving, temperature or noise becomes unacceptable, or the workload shows instability.
AMD’s support guidance states: “When manually overclocking, it is a best practice to overclock in small increments and then test for stability after each adjustment.” A higher displayed clock is not success by itself; use sustained score or frame rate and the card’s thermal and acoustic behavior as the test.
Memory tuning
Increasing VRAM frequency can help workloads that are sensitive to memory bandwidth, but it can also produce subtle corruption or crashes before an obvious failure appears. Change memory separately from the core, test the same workload, and watch for shimmering textures, speckled pixels, geometry errors, or a driver reset. If any appear, return to the last stable memory setting.
Undervolting for performance per watt
An undervolt reduces voltage while attempting to maintain a useful clock speed. AMD describes this approach as improving performance per watt rather than simply chasing a higher peak frequency. Lower power can reduce temperature and fan speed, which may allow the card to sustain its clock longer. The best result may therefore be a similar benchmark score at lower power, not a larger headline clock.
Lower voltage is not automatically stable. Apply a small change, test it, and verify it in both a benchmark and the applications you normally use. A setting that survives a brief test can still fail after a longer heat-soaked session or in a different game.

- Good Insulation and Heat Resistance: Case fan uses PBT environmental protection material, with good insulation and heat resistance, tough and durable quality
Power-limit adjustment
A power-limit increase can give a card more room to sustain a requested clock, but it also permits higher power and heat. Treat it as a separate experiment. Record board power, temperature, fan speed, and sustained clock, not only the final score. If the workload is already temperature-limited, adding power may increase noise without improving performance.
Fan-curve tuning
A more aggressive fan curve can lower temperature and help sustain clocks, at the cost of noise and potentially faster fan wear. A quieter curve may be preferable for a lightly loaded or acoustically sensitive system, provided temperatures remain within the manufacturer’s operating guidance. Laptop fan controls may be unavailable or managed entirely by the system firmware.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Validate every change safely
Use a two-stage test
- Apply one small change and run a short stress or benchmark pass to catch immediate crashes and artifacts.
- Run the same repeatable benchmark used for the baseline and record score, frame rate, utilization, clocks, temperature, power, and fan behavior.
- Play the games or run the applications you actually care about for a normal session. Different engines exercise different parts of the GPU.
- Repeat a longer, heat-soaked run after the card has reached its normal sustained temperature.
- Keep the setting only if performance or efficiency improves without unacceptable temperature, noise, or stability costs.
Recognize instability
- Application crashes, hangs, or a black screen.
- Driver resets or recovery messages.
- Flashing polygons, colored speckles, texture corruption, missing geometry, or other artifacts.
- A lower score despite a higher requested clock.
- Unexpected clock oscillation, excessive temperature, or fan behavior that makes the system unpleasant to use.
AMD’s guidance recommends returning to the last stable settings when instability appears. Do that immediately rather than stacking another change on top of a failing one. If the display becomes unstable, use the saved stock profile or reset tuning from the vendor software after restarting.
Be cautious with extreme stress tests
A synthetic stress test can reveal problems, but it is not automatically representative of a game. NVIDIA warns that “Furmark is an application designed to stress the GPU by maximizing power draw well beyond any real world application or game.” The warning was updated September 29, 2021. Do not disable over-temperature or over-current protections; NVIDIA warns that doing so can permanently damage a card and may void its warranty.
Use the shortest test that answers the question, monitor the card continuously, and stop if temperature, power, noise, or behavior becomes abnormal. Manufacturer warranty terms differ, so check the exact product’s terms before modifying operating settings.

- PRECISE MANUFACTURING FOR MAXIMUM SMOOTH RUNNING: Minimal gaps, automatic balancing and high-precision measurement noticeably reduce vibrations – for quiet, efficient and long-lasting performance
- SMOOTH-RUNNING FLUID DYNAMIC BEARING (FDB): The self-lubricating bearing minimizes noise during operation – ideal for quiet, efficient cooling and a long, reliable service life
- NEW FAN BLADE DESIGN FOR MORE PERFORMANCE: The redesigned rotor blades offer an optimal balance of performance and low noise – especially efficient at low speeds
Compare profiles by the result you value
Run every profile through the same scene, resolution, settings, and duration. A useful comparison records the complete trade-off rather than selecting the largest single number.
| Profile | What it changes | Measure | Typical trade-off |
|---|---|---|---|
| Stock/default | No manual tuning | Baseline score, frame rate, temperature, power, fan speed | Reference point; no tuning risk |
| Core-focused | Small core-clock increase | Sustained clock and frame rate or score | Potentially more performance, power, heat, and noise |
| Memory-focused | Small VRAM-clock increase | Bandwidth-sensitive workload and artifact-free stability | Potential performance gain with corruption or crash risk if excessive |
| Undervolted | Lower voltage at a useful clock target | Performance per watt, sustained clock, temperature, noise | Lower heat and power; stability depends on the card and workload |
| Quiet fan curve | Lower fan response | Noise and long-run temperature | Less noise, potentially higher temperature or lower sustained clocks |
| Cooling-focused | More aggressive fan response or corrected case airflow | Temperature, sustained clock, acoustic level | Better thermal headroom at the cost of noise or hardware changes |
Report observed results only for the specific card, driver, system, and workload tested. AMD’s product material describes a test conducted on August 18, 2021 with a Ryzen 5 5600X, 16 GB DDR4, a Radeon RX 6600 XT, Radeon Software Adrenalin 21.9.1, Auto Overclock enabled, and 1080p ultra-quality game settings; AMD cautions that results may vary. That test context cannot be converted into a promised gain for another GPU.
Recover from a failed setting
The game crashes or shows artifacts
Close the application, reload the last stable profile, and rerun the baseline workload. If the problem disappears, the most recent change was not stable for that workload. Reduce or remove that single change before trying anything else.
The driver resets or the screen goes black
Restart the system if necessary, then use the vendor software’s reset or default function. Load the saved stock profile before testing again. Do not continue raising voltage, clocks, or power limits to “fix” an unstable setting without first returning to a known-good state.
The score is lower after tuning
Check whether the card reached a higher temperature, reduced its sustained clock, hit a power or thermal limit, or encountered a CPU-limited scene. Compare the complete logs with the baseline. Revert the change if the measured outcome does not improve the target metric.
The controls are unavailable
Feature availability varies by GPU generation, driver, firmware, and laptop policy. Use the controls the supported software exposes, and keep the system at default when a required control is locked. Missing controls are not evidence that a hidden setting should be forced.
A practical, low-risk sequence
- Identify the exact GPU model, driver, desktop or laptop form, and target game or application.
- Inspect vents, dust, airflow, background load, frame caps, and likely CPU limits.
- Record at least one repeatable stock run with score or frame rate, utilization, clocks, temperature, power, and fan speed.
- Save a default profile and select one goal: performance, efficiency, temperature, or noise.
- Use the supported vendor control panel or utility and change one setting by a small amount.
- Run a short stability check, then the identical benchmark and a normal application session.
- Keep detailed notes, including the setting, date, workload, result, and any failure symptoms.
- Restore the last stable profile immediately if you see artifacts, crashes, resets, abnormal heat, or a worse result.
- Save the validated profile separately from experimental profiles, and retain the stock profile for troubleshooting.
The useful endpoint is the profile that improves your chosen metric under your real workload while remaining stable and acceptable for temperature, power, and noise. That may be a modest overclock, an undervolt, a fan adjustment, corrected airflow, or simply the untouched default profile when the workload is limited elsewhere.
