I have the same board and live in queensland, am expecting my 5950x in a few days by post. I am relishing troubleshooting as just doing a fresh install with my 3900x has caused nothing but headaches.WOW, reading these issues just makes me want to wait. And this is a ~$1200 motherboard in Australia. You'd expect the highest end boards to get the fastest release for fixes. But at least in Australia we are protected by Consumer Laws, basically I would have 0 problems returning the board and getting a full refund if it had these issues. Sadly in other countries you have to contact Gigabyte, here it's not my job to contact Gigabyte, the store you buy from has to deal with them.
Try my tip for spread spectrum, that affects the base clock mate, should hopefully see some stability.Updated to F31h
Clear CMOS via back IO button for good measure.
Entered UEFI and noticed FCLK is 104.4 Mhz. Weird. never seen it so high on auto. Set it to manual 100.
Rest on default.
Problem remains. Windows crashes, Ubuntu live does not even boot.
Set VCORE SOC to 1.000 and I could boot Windows, but crashes under Aida64 memory copy and most games.
Tried almost all combinations of VDDG, VDDP, VCORE SOC, IF, RAM Speed, LLC, etc.
The higher the VCORE SOC, the most likely Windows will not even boot.
No matter the combo, Aida64 will crash on copy benchmark as well as most games. 100% will crash at idle after some time or just internet browsing with WHEA uncorrectable error BSOD.
The only setting that gets this rig stable is setting "Core Performance Boost" to disabled.
With it disabled, I can set everything else on Auto and will work just fine.
On the upside, somehow it seems F31h is very stable when changing various voltages, like VDDP/G.
Up until now, a lot of times when changing anything voltage related, the board will beep twice and reboot 3 times. Somehow F31h fixes this for me.
Early adopter's tax. No hardware is immune. I always wait for the kinks to get ironed out.Have a couple of X570 and B550 boards I can test the CPU on, in remote offices. Will try to test there.
In my 20 years working in IT I never once bought or had to service a defective brand new CPU. I had lots of defective boards though.
All over the internet people are starting to post about issues with 5950X, 5900X and WHEA crashes and reboots. I guess if more units were available at launch, even more people would have posted.
I am 99% sure this is a firmware issue, with AMD AGESA or Gigabyte (or both)
I just hope the fix comes sooner rather than later.
Pretty disappointing to pay for a Ferrari only to find you have to keep it under 90 Km/h.
Nevertheless, will try to test the CPU on an Asus and MSI X570 and B550 and get back with details.
