I'm posting this issue in several places, to try to find some hints what wrong is happening here. I will describe the whole tour I made with my new PC. I hope it is a good way of giving some ideas what is happening. I currently suspect the motherboard for this issue, but CPU or RAM isn't out of the question yet. I hope you might have some ideas...
My specs:
GPU: NVIDIA GeForce RTX 4070 Ti (AD104-400) [ASUS]
CPU: AMD Ryzen 5 7600X
Motherboard: ASUS TUF GAMING X670E-PLUS WIFI
BIOS Version: Previously 0807, Currently 0821
RAM: 2x16GB G.Skill Trident Z5 6000MHZ CL36 (F5-6000J3636F16G)
PSU: beQuiet! Pure Power 12 M
Case: Fractal Pop Air
Operating System & Version: WINDOWS 10
GPU Drivers: GEFORCE GAME READY DRIVER - WHQL Driver Version: 528.49
Chipset Drivers: 4.1.02.829
What is happening:
System degrades it's stability depending on the current max clock setting in PBO options in Motherboard's BIOS. Ranging from outright Windows Bluescreens on "default" clock boost values (5.450GHZ - yes, it's weird, I will explain), to crashes in Time Spy at -100MHz, to crashes on 4K display in Forza Horizon 5 benchmark at -150MHz, to seemingly normal operation at -200MHz.
Troubleshooting:
- The best way to explain the situation would be to describe every single action I took so far.
- PC was build in a electronic store. Due to shortages of parts, store provided everything except PSU, SSD, Cooler and Case. Those elements were purchased separately
- Store build the PC, turned on XMP profiles, installed Win10 and tested the system on some unspecified benchmark.
- Brought PC to home. Started testing. System worked well.
- Started testing on Time Spy and FH5. Had crashes: 3DMark aborted tests and FH5 crashed to desktop
- Investigated. Disabled XMP profiles in BIOS first. Frequency of crashes lowered, but didn't dissapear.
- Updated MoBO's BIOS from 0807 to 0821. No dice
- Found this thread: https://community.amd.com/t5/processors/amd-7600x-am5-7000-platform-instability/td-p/567604 with similar symptoms. Per information there, I turned that option, not exactly knowing what it does. Max CPU Boost Clock Override (-) = 150. I'm not that knowledgeable in overclocking. I was thinking that my MoBo was configured so no additional OC was set up.
- Question 1: Why does exactly this ASUS motherboard allows up to 5450MHz Boost clock?! I thought that 5.3GHz is allowed max without OCing.
- Question 2: What does AUTO option in PBO settings exactly entails? So far I had it to auto. I have no idea if that makes PBO turned on or off by default.
- Testing at -150. Enabled XMP again. Every benchmark passed with flying colors!
- Next day: Hooked up 4K TV. FH5 benchmarks started failing again.
- Went to BIOS. Set up -200 for a limit
- Tests returned to normal. No crashes in FH5 or in HL: Alyx for that matter.
- Next day: Decided to do more investigations. Wanted to try a MemTEST86
- Went to BIOS. Wanted to go for the default settings so I reset it to "Optimized Defaults" per Asus BIOS
- Windows went haywire. Bluescreens everywhere. Different reasons. I cannot stay in system for more than 30 seconds. Using WhoCrashed app to highlight issues, those are several of errors I have got: SYSTEM_SERVICE_EXCEPTION, ATTEMPTED_WRITE_TO_READONLY_MEMORY, SYSTEM_THREAD_EXCEPTION_NOT_HANDLED_M
- Enabling/Disabling seems to have no effect.
- Reducing clock speeds by -150 seemed to make Bluescreens go away.
- Making PBO: DISABLED in BIOS, triggered Bluescreens again.
- Tried MemTEST86. When CPU clock speed was limited by -200, both on/off XML profiles passed test with no issue.
- MemTEST when CPU clock was not limited (Auto). I don't remember exactly, but it seemed that non-XMP test passed, but having Auto PBO settings and XMP made either immidiate test errors or I couldn't enter MemTEST at all (stuck on Calculating Memory/CPU speeds)
I hope for some explanations what the hell is going on here. I would much appreciate any clearing on this issue
