BIOS values keep changing when running stress test

[KORNO]

CPU: i5 6600k

MOBO: MSI Z270 Mortar Micro

GPU: gtx 1060

PSU: Corsair 500w

RAM: 2400mhz ddr4 

 

I overclocked to 4.6ghz with 1.21v (which should be an instant crash but it isn't crashing). afterward, I stress tested through aida 64 and my cpu clock keeps changing from 3600-4600 MHz (even though I have my cpu clock set to FIXED). and the voltage is also changing up and down anywhere from 1.21v-1.26v (even though I have it on OVERRIDE). I also disabled intel's speed step tech and EIST and I also disabled the C-state. but it looks like my computer doesn't want me to do anything manually and I'm trying to find a stable overclock but all my values keep changing!!

sounds like a throttling issue either by core disable or straight speed reduction.

what voltage was stock for 3.5GHz?

sounds like you need more if the temps aren't out of sight.

although you have a manual setting in voltage, VDROOP/LLC are more controls to stabilize core voltage. increasing the LLC can stabilize the VCORE fluctuations.

For starters, don't use AIDA, it's a potato test. I recommend Prime95 (latest version), but OCCT works too.

 

Next, the voltage thing. Just because you set it to X value doesn't mean it'll actually run at that; Vdroop and LLC can and will affect your final voltage.

 

As for the clock fluctuation, it could be temps. Post a print of HWMonitor while under load (and as I said, using a real stress test), let's seee what's happening with that PC of yours.
