Core Voltage for i9 9900k

[nitewulf69]

I recently built a new gaming PC with an i9 9900K, Asus ROG Strix Z390-E, and Asus 2080ti. I enabled XMP profile 1 in the bios to get the 3200 speed from my RAM. I'm also using the high-performance profile in Windows which apparently, along with the XMP profile is giving me a multiplier of 48-50 which seems to vary. I made no other changes as far as OC settings go. I notice in CPU-Z (see screenshot) that the CPU core voltage seems to fluctuate from as low as 0.693 to just over maybe 1.01. Shouldn't the core voltage be around 1.350? Can I set it in the bios so it doesn't fluctuate and if so, what do you recommend? The only performance issues I'm having is a very occasional totally blank, blue screen. I've tested my RAM and PSU is a new EVGA 750W G+. I ran SFC and DISM which found no errors. Could it be the voltage is dropping too low? I'm new at this so any help would be appreciated.

Put a real load on all cores and you'll see where the voltage goes.

Ditto. Keep open on your desktop a good temp/voltage monitoring program such as HWInfo64 and watch the numbers as you run a stress test such as Prime95.

A "totally blank" blue screen? Usually, you get some text message with blue screens. Could this one suggest a video card or video card driver issue?

Please give us more complete hardware info about your system. In fact, we would appreciate it if you would create a "Signature" to capture that info that will travel with every post your make.

Thanks for the reply. I've only actually had one totally blank blue screen. I'm using the latest GeForce driver. I haven't had any other issues with the graphics card which is new.

Well, if you have another issue, that is when I would consider worrying about it.
