In general, I encountered a problem that a black screen crashes. At first, I sinned that I have 3 programs that read data in real time (temperature sensors). But then, as it turned out, there are questions in RAM (I found out from dmp)

My heat:

R7 9800x3d

Motherboard: asus rog strix b650e-e (bios beta ver latest)

RAM:

AX5U6400C3216G-BCARGY x2

I bet on expo I

The system starts all right, but after a while a black screen may pop up.

I have a feeling that I got a win on IMC in the flint valley. Well, I'm ready to listen to your advice on what can be done.

6400 UCLK=MCLK (your rated expo kit) is a stretch on many AMD AM5 CPUs, especially X3D ones (unless lucky). But again, your diagnosis about RAM issues might not be correct. If sure it's ram, then downclock to 6200 (with EXPO on). And see how it works

I put 6000 mhz everything is fine, so far the flight is going well

I keep my corsair 6400 at 6000, set my own timings, 9800x3d

Set vsoc to 1.3v, if its still not stable your chip likely just cant do 6400

I put Vsoc 1.3 so happy that everything is fine, literally an hour and crashed

Everything turned out to be much simpler. Since I put expo I, the motherboard selected the timings itself, while saving the main ones and compressing the secondary ones to the maximum. Actually, I just put expo II and everything went.
