Can you try using 2 sticks only? I feel like AMD 7000 series memory controller is a bit unstable with 4 sticks. In the official specs on their website they officially support 3600MHz when using 4 sticks 💩

Also running with unstable memory and using windows, installing drivers etc might have corrupted a bunch of stuff. It's probably best to clean install windows again.

i have done idk. maybe 15 clean installs of windows. still problems and problems. ive replaced everything and i have spare parts for all of it just to test equipment. its insane. asus makes the rma experience hell on earth and i really dont want  to go that route

[tsk7mde]

I have the exact same problem!
And from ASUS Support no info or help! With supported components! So crazy.

I've now increased the RAM voltage significantly. I have now clocked the modules with 5600 Mhz.
BIOS: 1.285v
Let's see if it improves.

[tsk7mde]

The stability hasn't improved 😵

[Silent_Scone]

Have you tried with two modules yet? 4 DIMMs can be challenging for some CPUs on AM5. Yet another reason why no vendor guarantees overclocking. Try increasing VDD/VDDQ to 1.3 - 1.35v.

[tsk7mde]

I now only have two RAM modules in the PC. Let's see if it helps.

ASUS should urgently work on the BIOS it's a shame that the supported modules don't even work with 2400Mhz or 4800Mhz and
no information from ASUS Support.

There is actually 1515 version of BIOS in the X670 resource thread and it contains AMD agesa 1.0.0.7b, which promises to improve memory speeds and stability. It's worth trying.

Also don't flash BIOS if your memory isn't stable. Get it stable first

[tsk7mde]

Voltages of 1.3 - 1.35 brought no success. With 4 modules.
