Hello,
Please vote on the pool only if your system is not stable with BIOS defaults, memory at 2133 Mhz without XMP, without any CPU or RAM overclocking, without PBO or any voltage tweaks and of course, if you do not have any issues with your Ryzen 5000 or your problem has been fixed.
* you can select 2 values.
Motherboard+CPU if you have issues.
No, I tested extensively for several days+CPU if you do not have issues.
It did, but *+CPU if your issue has been fixed.
See https://www.overclock.net/threads/replaced-3950x-with-5950x-whea-and-reboots.1774627/post-28698010 for the solution to my issue.
I bought the new AMD Ryzen 5950X to replace my AMD Ryzen 3950X.
This is the only new component in the system. The rest of the components are in the signature.
Problem
What I tried
Temporary fix
With F31h Windows no longer crashes at boot, but crashes under load or random at idle like before.
The fastest way to crash the system is to run AIDA64 memory copy benchmark (will crash when CPU will reach 100% usage), a Handbrake encode (will crash as soon as it starts encoding) or a game (Guild Wars 2 crashes at login screen).
Opened a ticket with Gigabyte, but knowing Gigabyte, their response will be "We will inform our engineers" and then silence.
Opened a ticket with AMD.No response. Received an email requesting some details. Still waiting. Received another email requesting details already sent in the original RMA ticket. I guess AMD support and Gigabyte support are outsourced at the same helpdesk. RMA accepted after 5 weeks: my reply to AMD.
Anyone else having problems with the new 5950X and Core Performance Boost?
Thank you.

Problem
As soon as I booted up to Windows, the system started rebooting and crashing, sometimes with the BSOD WHEA Uncorrectable Error
What I tried
Long story short:
- I have replaced every component except the CPU and the motherboard.
Long story:
- removed all RAM sticks and tested with only one at a time in different memory slots.
- tested with memory at 2133 Mhz auto timings, XMP and manual timings without XMP.
- took out my RAM and tested with one stick of G-Skill F4-2400C15S-8GNS and one KIT of 2 sticks Corsair CMK8GX4M1A2400C16.
- replaced the PSU with a Corsair AX760i
- removed any other USB devices besides mouse and keyboard
- tested with only a Bluetooth mouse. No other USB connected.
- removed any other HDD and SSD besides the system/windows one.
- replaced the system/Windows SSD and tried reinstalling Windows. Crashes while installing.
- removed the CPU to check for bent pins with a magnifying glass. Twice. All good.
- downgraded BIOS to version F30.
- re-flashed BIOS version F31e.
- upgraded BIOS to F31h, F31i, F31k, F31l, F31n, F31o, F31
- cleared CMOS and tried booting without setting anything in BIOS.
- booted Ubuntu 20 Desktop live USB. Crashes before desktop with some cryptic error about CPU.
- checked CPU and motherboard temperatures. All fine.
- reseated the GPU.
- tested with an RX 460 GPU instead of GTX 1080 ti.
- tested with an RX 590 GPU instead of GTX 1080 ti. Takes longer to crash than with the GTX 1080 ti on BIOS version F31n.
- disabled C-States
- disabled HPET-Timer
- forced PCIe to gen 2/3/4
- disabled AMD Cool&Quiet
- disabled PBO (always have it on Auto anyway)
- removed all SSDs and HDDs and tried booting from Ubuntu live USB
- tried all levels of LLC
- Enabled Preferred Cores
Temporary fix
After many failed attempts with various BIOS settings, the only one that fixes this problem is setting "Core Performance Boost" to disabled. Of course, with this setting disabled, this new CPU performs a lot worse than the old 3950X.
With "Core Performance Boost" disabled, I can run my RAM at 3600 and IF/UCLK at 1800 with tight timings without any problems. 300+ Handbrake CPU stable encodes so far.
With F31h Windows no longer crashes at boot, but crashes under load or random at idle like before.
The fastest way to crash the system is to run AIDA64 memory copy benchmark (will crash when CPU will reach 100% usage), a Handbrake encode (will crash as soon as it starts encoding) or a game (Guild Wars 2 crashes at login screen).
