Yes, perform a stress test on the CPU to ensure undervolting remains stable.

For checking stability after undervolting with ThrottleStop, a reliable tool is essential. Consider using a monitoring application like HWMonitor or Core Temp to track temperatures and performance metrics.
I ran looping Cinebench and Prime95 too. The actual stability check begins once you use the PC under normal conditions. Often I experienced an overclock that stayed solid for long in simulations, but failed when a specific program or game was launched.
OCCT offers a solid solution. It evaluates both full-core and single-core stability well and delivers strong results. I've tried it with both Intel and AMD setups, and it revealed instability in applications such as Cinebench and Prime95 despite appearing normal.
Thanks! I’ll use both Prime95 and OCCT as planned.
Regarding your questions:
- The free OCCT version offers just about an hour of stress testing; that might be sufficient depending on your needs.
- For Prime95, decide how long you want to run it based on your system’s capacity and goals.
I successfully executed OCCT for a short duration using AVX2, Extreme, and Variable instructions per core on my 5900X processor one at a time to check PBO Curve Optimizer settings and undervolts. The Intel 9600K also performed well with voltage offset adjustments. Both systems experienced errors or crashes during instability, but none failed under load or when idle. An hour should suffice unless you're extremely close to stability.
