Wierd boot problem

[Jackbeefcake]

Hello I’m new to the forum, however I’m long time youtube subscriber. Recently I decided to build PC as a gift for my father. PC is already built and running except for one thing I cannot solve…

First the specs: 

 

AMD RYZEN 5 7600X

 

ADATA XPG 32 GB KIT DDR5 6000MT/s CL30 Lancer Blade Black

Samsung 990 EVO Plus 1 TB

 

ASUS PRIME B650-PLUS WIFI

 

XFX Swift AMD Radeon RX 9070 XT White 16G

 

GIGABYTE UD850GM PG5W

 

windows 11 pro

 

So I’ll try to describe my issue. When I set my rams to EXPO 1 or EXPO2 at ram specs(6000mhz) basically I just set expo profile in the bois.
 

Then this happens:

System is stable during Cinebench, 3D Mark, OCCT, Memtest, Gaming etc… However when I restart pc(in windows start button->restart) AFTER heavy load for example Cinebench or OCCT ram test. Instead of restarting, pc will trun off, I can hear click from psu and then it will start. It happens every time after Cinebench run and restart. System will not post. Power led will blink rapidly and it will be stuck. I have to restart via button few times in order to boot in safe mode. During these restarts power led is blinking randomly.. sometimes fast sometimes slow. It can take 10 button power on/offs to post in safe mode. When turning off and not restarting pc there are no problems. And when restarting after not heavy load just sitting at desktop for example, it works… Also it could get stuck after waking up pc from sleep. But this is hard to replicate. 

 

After hours/days of trying I came up with halfass solution(I was trying a lot things before I came up with this). I used expo 1 , and set rams to 5200mhz, DDR voltage at 1.375V(from 1.4V set by expo). And it kinda works. Now when I restart pc AFTER heavy load. It will try to restart (no psu click this time) but it will get stuck. However there is no blinking power led. And after powering it off via button it will post on 1st try. And again this happens only after heavy load and only when restarting. When I turn off PC everything is fine. I think issue when pc is sleeping is not happening but I’m not sure its hard replicate. Oh and btw this also happens with ram profile set to auto (no expo). And then ram is runing at 4800mhz. 
 

At first I thought it was something with my tuning/undervolting of cpu. So I put everything on bios defaults. Behavior is same no matter what. I updated bios, turned off windows fast boot (in bios and in windows) I tried s4/s5. Installed chipset drivers. Checked cables in the pc 10times, reseated cpu, I checked ram slots and every connection in the pc. All seems to be ok.
 

Oh and OCCT ram test no error same for memtest86(in all settings). 
 

Honestly it took me huge amount of time and I’m sick of it I’ll just leave it as it is. But at the same time it kinda bothers me. Its a gift and I want it working 100%. I have put a lot of energy in the built. It looks nice, cooling is sorted, cable management is sorted, it has games installed, it’s tuned, temps are ok. Then I restarted after stress test and nightmare came

 

It’s very weird behavior, seems like when ram was at high usage its not detectable or idk... 

 

Any ideas what this can be?

 

Anything will be much appreciated. Thanks!

powercycling that many times is likley to corrupt your windows install imo its hard to know if your pc was just memory training till you powercycled it to get it into safe mode.

 

I think i would re-install windows before you do anything else. 

 

Is bios up to date?

Bios is up to date. Hmm memory training is happening after windows restart? Can I somehow trigger memory training?

[Jackbeefcake]

I tried reinstalling windows. First 4 tries it worked. After that its happening again. I think I give up. This is the last time that Im buying amd components.

Update: after trying everything again, reinstalling windows, flashing bios again. It was the RAM modules. Adata xpg is listed as supported on asus website but they clearly are not.  I swapped for partiot viper DDR and it works. On full 6000mhz EXPO1 no restart issues.
