Yep -250mV undervolt and is stable at least with aida64 for the 30mins I ran it for (Stressed CPU/FPU/Cache).is that -0.25V? as in -250mV?
That's a pretty substantial undervolt!
Did you cause any BSOD when going lower than that?
GPU and CPU benchmarks simultaneously can be used to simulate real gameplay.
I run MSI Kombuster to get the GPU nice and hot
then run CPU-z with a limited thread count and increment the count gradually to gradually test different loads on the cpu.
The GPU benches don't stress the cpu enough, and the GPU benches hardly bother the cpu and don't really give a good real world example.
optimising for both seperately tended to end up with a lot of throttling for me when I actually started using them
I'll definitely test out your method for stability, but give me 2 weeks from now. Will update once I get it tested!
