A graphics card undervolt resets after reboot because most curve editors do not run automatically at Windows startup, so the profile never reapplies. Evetech recommends setting the utility to launch on startup and minimised, since that fixes most cases.
A GPU undervolt lives in the tuning utility that created its voltage-frequency curve. If that utility does not start, load the saved profile or apply it after Windows settles, the card returns to default behaviour. Make the profile stable before automating it; an unstable curve applied at every sign-in can trap you in repeated crashes.
Save the proven curve as a named profile and confirm it survives several demanding games without driver resets. Reboot and test the utility's manual profile load. Only then enable its supported Start with Windows and apply-profile-at-startup options. Add a short launch delay where available, and keep a default profile or Safe Mode recovery path.
Evetech's NVIDIA graphics-card range gives you model context for the card being tuned. The GPU best sellers help compare an upgrade path when efficiency tuning cannot solve a cooling or performance limit.
An undervolt that passes one benchmark can fail in a different game, video workload or light-load clock state. Test several engines, ray tracing where relevant, idle-to-load transitions and a long warm session.
Watch for driver resets, black screens, artefacts, application crashes and corrected hardware errors. Increase voltage or lower the target clock when any appear.
Keep memory tuning at default while proving the voltage curve. Two simultaneous changes make the crash ambiguous.
Use the utility's Save function and assign the profile to a clear slot. Write down voltage, frequency, power limit and fan curve. A screenshot helps after an update resets the interface.
Close and reopen the utility, load the profile and confirm the curve editor shows the expected points. Run a short test. Saving a slot does not always mean it applies on its own.
Export the profile only through the tool's supported method. Do not copy configuration files between different GPU models.
Turn on the utility's normal Start with Windows or startup-task option. Configure it to launch minimised when supported. Then enable the setting that applies the selected profile after launch.
A delay can let the graphics driver and Windows desktop initialise before the curve is applied. Use the tuning utility's documented option rather than building an opaque script.
Reboot twice and inspect the live curve each time. Do not assume the tray icon proves the profile loaded.
Graphics-driver updates, utility updates, Windows changes or a detected crash can restore defaults. Some tools disable automatic application after an improper shutdown to protect the next boot.
Read the utility log and check whether Windows Security or permissions blocked its startup task. Recreate the supported task rather than running the whole program as administrator without need.
A card firmware or hardware fault cannot be fixed by forcing the undervolt to load earlier.
Keep a default profile and know how to start Windows Safe Mode, where the tuning utility should not apply its normal graphics profile. Disable automatic apply before pushing a new curve.
If Windows crashes at sign-in, disconnect from unnecessary displays, enter Safe Mode and remove the startup task or reset the tuning utility. Do not keep racing to click Reset between crashes.
After recovery, return the card to stock and run a known load before rebuilding a milder curve.
Log stock and undervolted power, temperature, clock, noise and frame time in the same game. The goal is equal useful performance at lower power or noise, not the lowest voltage in a screenshot.
If the profile lowers clocks in the hardest game or needs an aggressive fan curve, revise the target. Silicon, cooler and workload decide the stable point.
A custom fan curve can make the undervolt look stable by lowering temperature, while an automatic profile may later load one setting without the other. Prove the voltage curve on the normal fan policy first, then add the fan adjustment and save both deliberately.
After reboot, verify voltage-frequency curve, power limit and fan control separately. Some tools store them in the same slot but apply them at different points in startup.
Run one program that writes GPU clocks and voltage. A motherboard suite, graphics vendor tool and third-party curve editor can overwrite one another during sign-in.
Remove duplicate startup tasks and keep one supported control path. Sensor monitors can stay read-only, though their overlays and polling should be tested for game compatibility.
If the curve resets at random rather than every reboot, check which utility launches at that moment and whether a driver recovery occurred in Event Viewer.
The GPU starts at defaults and the tuning utility must launch and apply the saved profile after the driver loads.
Yes. Recheck the utility, profile and stability after graphics-driver or tuning-tool updates.
It is sensible only after the curve is proven and you have a default profile and Safe Mode recovery path.
Prove the curve across several games, save and reload it manually, then automate only the stable profile with a recovery path ready.

Install a liquid CPU cooler by confirming case support, following the model's mounting instructions and connecting pump and fans correctly. The DeepCool LQ360 included with this kit should be verified for operation and temperatures before any performance tuning begins.

Good cable management routes power and data cables behind the motherboard tray and clear of fan paths, measurably improving airflow over a case full of loose cables. Evetech builds route cables this way at the factory, worth repeating whenever the case reopens later.

A fibre connection only stays alive if the entire chain, ONT, router and any mesh node or switch, is on backup power, since missing even one link breaks the connection regardless of the others. Evetech's mini DC UPS units cover this full low-draw chain in one go.
