clock watchdog timeout BSOD occurring under weird circumstances

One of the most commonly done tweaks to computer systems for the purposes of audio work is to disable turbo boost and EIST in the BIOS, resulting in all the cores running at the same base clock frequency.

I just finished building a new system with a 7820x, MSI X299 Raider and 64gb RAM. I ran memtest86 for 20 hours and RAM passed with flying colors, I then went into the BIOS and made the aforementioned tweaks as I've done to my 2 other systems and have had no issues whatsoever.

I then installed Windows; windows installed fine no issues.

As soon as I start to install the graphics driver, I get the BSOD error "clock watchdog timeout". Googling shows that it's basically the CPU cores aren't playing nice together. It's not drivers cause I haven't even had the opportunity to install drivers, so I reset the BIOS back to default and it seems to work fine although it takes forever to boot (it hangs at the MSI logo as if it's going to crash for awhile but then goes to the windows login).

I've tried tweaking the BIOS settings in any combination but disabling EIST or turbo boost causes the BSOD after I login to windows. The keyboard and mouse are unresponsive/EXTREMELY laggy and then in happens.

What's even more bizarre is that task manager shows the CPU running consistently @3.6ghz, not changing speed even though EIST is on??

At this point I'm throughly confused as to what's happening. I'm inclined to think that the CPU is bad, but other internet sources say that's usually not the case. Any help here?

bit peculiar you cant alter power settings

but never had one of those cpus myself

normally that error would suspect the cpu

but learned never to say never regarding pcs

so yes could try removing some of the non essential hardware just to see if it cures it

Is that possible at the OS level? I didn't think that it was but maybe I've just never learned how to do it, I know that those aren't in the power options, so where would they be located?

actually yes its in power options

but done in a way that wouldnt appear to do it

do you essentially want

1--turbo off

2--not to downclock

if so go to power options

change plan settings

change advanced power settings

processor power management

maximum processor frequency--set this to 99

and minimum processor state--also set to 99

surprisingly this disables turbo

and keeps you at the max non turbo speed with no downclock/speedstep

and use cpuz to check cpu speed its more accurate than task manager

edited--and it seems you want all the cores at the same speed?

dont do audio work but guess theres a reason for it

a lot of motherboards have a turbo all cores option

that would achieve the same thing and result in all the cores also being at a higher speed

assuming your motherboard has a turbo all cores option of course

Turns out for some reason the Min and Max CPU settings aren't available to me in the power options.

Anyways, the important thing that happened was I installed CPU-Z and when I ran it and it started scanning the hardware I got the BSOD error again. This is with default BIOS settings btw

This is looking like a hardware issue more and more, unless there's some other explanation. This is a basic a system as you can get as far as software goes, all I've got is Windows on there

EDIT: CPUZ hangs (and then the computer crashes) when it gets to scanning the PCI hardware, I wonder if maybe one of the PCIE cards I have installed has something do with it?

Turns out it was the infiniband adapter that I use to stream the files from my storage server. Guess that means the card is f'd up somehow, what I get I suppose for buying it off ebay

bummer

though at least it wasnt something major meaning having to dismantle parts of the build
