X670E PG Lightining stuck on boot when restarting

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   So, I got back a new motherboard after a month, the store had to send me one since from ASRock there was no response after 30 days.

I reinstalled everything and the first thing I do is restart the system to see if I still have the issue...and it still happens.
So the only thing that could be is the RAM kit, even though it is listed on the Memory QVL and it's stable on every stability test I ran. 
So I bought a new RAM kit, this time EXPO instead of XMP and it's also Hynix instead of Samsung and everything works fine. I restarted several times now with EXPO applied and the settings are always applied correctly and no more being stuck (CPU/DRAM leds stay on) after restarting either.

Just wanted to leave this here if someone else has similar issues. My theory is that my kit and most likely some other RAM kits are not compatible with these motherboards. I've seen some posts on reddit with B650 boards as well experincing the exact same issue with XMP RAM kits, so it is most likely this.
I've reported my findings on an ASRock support ticket so that this can be looked at.
Everything is fine now.

	Re-enabling EXPO still works.

	Just a quick follow-up. I backed the BIOS version up to 1.11.AS03 and I can restart my machine from Windows again. I need to go back and re-enable my RAM EXPO settings but rolling the BIOS back a version helped.

	Up until today, I was not having this issue. System has been running stable since mid-December. Then I updated the bios from 1.09 to 1.18 and any time I restart now I get CPU and DRAM error LEDs. I'm going to try and revert back to the pervious BIOS and see if that corrects the problem.

	Had the same problem with X670 Steel Legend. They removed 1.14 from bios downloads. https://forum.asrock.com/forum_posts.asp?TID=25324&KW=&title=x670esl1-14-as06-steel-legend-firmware-removedpound Rolling back from 1.14 to 1.11 S3 solved the restart problem for me.

	Unfortunately the MB started having issues booting up from a cold boot, so it seems there is a defect. I was not even able to boot my system with Default BIOS settings. I believe that anyone that has this kind of issue should consider it a hardware defect and not bad BIOS (as I first suspected). I have RMA'd it and I'm waiting for AsRock response...

	I don't, I have a Noctua NH-D15. I also saw some reports about the pressure of the cooler causing some issues and loosed the pressure already, but had no success. I also checked for bent pins when I did that and everything is fine. I don't think it's a hardware issue, since I only have problems when restarting the system. If I only shutdown and turn on, everything is fine and stable...I'm guessing I need a new BIOS version to fix this but wanted to see if there are more people with this.
