Serious CPU Problems in My Server/Workstation Build

[cleric_warlock]

I'm building a professional workstation for serious freelance cad/fea with some AI compute hosting in the mix and I'm having a hell of a time getting Windows 10 or 11 to install and remain stable at all.

My build:

CPU - TR Pro 7975wx

Motherboard - Asus WRX90 Sage SE

RAM - Kingston DDR5 5600 256 GB (KF556R28RBE2K8-256)

GPU - NVIDIA RTX 6000 ADA

Storage - 2x 4tb Samsung 990 pro nvme ssds, 2x 18TB exos HDDs

PSU - EVGA 1600W T2 Supernova (Corsair AX1600i also used for testing)

What I've done so far:

1. Verified that all bios settings for windows 11 are in place (TPM enabled, CSM disabled, secure boot enabled, and the bios itself is on the latest version). Additionally, I made sure to say yes to the tpm reset prompt on first boot.

2. The GPU has passed extensive stress testing on both furmark and aida 64 on another machine.

3. Changing psus to the test psu confirmed to work on another machine (the corsair mentioned above) did not change any system behavior or resolve any problems.

4. The RAM was tested with the memtest bootable usb and passed 4 runs of tests 0 through 13 with no errors at rated EXPO.

5. The motherboard was suspected to be faulty and returned when it kept generating a phantom drive that would always show as the last drive on the windows installer drive search list and would always have a 0 byte capacity. Also, on boot to either windows 10 or 11, the operating system consistently fails to boot or if successful often encounters "whea_uncorrectable_error" BSODs. I replaced the return with another board of the same model and the system continues to have exactly the same problems, so it's probably not the mobo.

6. Removing all but the target boot ssd for initial windows install always fails in exactly the same way regardless of the individual ssd or slot used. My SSDs and HDDs also run fine on other systems.

This seems to leave only my cpu as a culprit - are there any diagnostic tools i can run (preferably bootable usb only) to diagnose exactly what is going on here before I try to make a return (still within my amazon return window). Is there anything else I'm missing here?

That motherboard has IPMI capabilities, the 0 byte drive is a virtual drive created by the IPMI which allows you to remotely mount a disk image and reinstall an os. Simply ignore it.

 

As for the BSODs try disabling EXPO.

Enabling or disabling expo makes no difference. Memory errors would definitely have shown in the memtest runs with OS instability this bad. Good to know about the ipmi controller!
