Confirm detection
Verify the GPU appears correctly in Device Manager and the vendor control panel. Close games, renderers, and other compute workloads before testing.
Practical note: Integrated and discrete GPUs may require different selections.
Test at stock settings
Start without overclocking or undervolting. Confirm that jobs are received and accepted before tuning.
Practical note: If the default setup is unstable, performance tuning makes diagnosis harder.
Tune carefully
Change one parameter at a time and record temperature, power, effective rate, rejected work, and stability.
Practical note: A small displayed speed gain can be a loss if power use or error rate rises significantly.
