It's 'normal' or at least - expected. AFAIK SVM and other VM stuff abstracts or hides the real HW and clocks/timers from both host and guest. IDK, might be wrong. I believe BLCK is actually ticking at a stable rate, it's just a matter of readings and reporting. Or I may be totally wrong. I'll be dropping a ticket to ASRock. I advise you all to do the same.

Same thing happens with my AB350M Pro4, tested with BIOS 4.70 and 5.00.

Sorry. Had to grab a backup drive to locate this in-depth link to understand.

I have seen that here. As others on the net have too.
It is my understanding that this is a normal occurrence as SVM is completely contained and executed within the processor itself. I've also personally experienced my OC's be hampered with SVM Enabled, FWIW. |

Hi.
I installed it because I want to use virtual environment Hyper-V. I activated CPU SVM in the BIOS. When SVM was enabled, BCLK was fixed, Installing Hyper-V will make BCLK unstable. Is there the same phenomenon? Why did you fix it? Help me. ---------- Windows 10 Pro April 2018 Update (Build 17134.5) Ryzen 7 1700 X370 Gaming K4 Power Plan : AMD Ryzen Balance Plan Stable BCLK Clocks -> 99.84 UnStable BCLK Clocks -> 97.86 - 98.47 ----------
