Not updating the status for 7900X3D.
Not updating the status for 7900X3D.
I feel really disappointed. I just set up my system today with a 7900X3D, an X670 Aorus Elite AX, 64Gb DDR5 (2x32) and a 3080Ti. When I turn it on, everything works fine at first, but then nothing changes. The CPU lights up briefly and the DRAM turns on, showing bright static red. I've tried using one stick of RAM in each socket, but it doesn't work. I updated the BIOS and checked the motherboard for bent pins, but I'm not sure what else to check. Please help me out!
Starting the session now for 30 minutes. I believe memory training should switch between CPU and DRAM regularly, but right now it seems static on the DRAM side. Also, I can't disable it by holding the power button. It appears I need to cut power from the PSU to shut it down.
Did you apply the latest firmware via the no POST system prior to any POSTing? Updating my x670e Aorus Master with the 7950x3D was a hassle. The only solution was using the rear button for no POST q-flash, but I made sure everything was posted beforehand. Clearing the CMOS might be useful—either by pressing a button/short or removing the CR2032. My build experienced some odd behavior during the first week with POST/BOOT settings, requiring several flushes. I only needed a dry power-on and never touched the CMOS, though it’s worth testing before you replace the DOA hardware.
Consider another pair of RAM modules. If it shows a red color on the DRAM and I can't see the owner's guide, doesn't accept the RAM, should I try another stick? Also, was the issue with the QVL?
I didn't do it. I constructed it with the expectation of functionality, connected it and received the same issue now. Then I performed a q flash to the newest firmware release. As a final option, I plan to revert the BIOS to version F3. If that doesn't resolve it, I may need to return it. I truly hope I haven't damaged any pins, though I can't confirm that easily.
It's likely the early RAM training didn't succeed. I'd try adjusting the CMOS settings and possibly replace the CR2032 battery to see if it resolves the problems. As discussed, there were several unusual issues during the first week—reboots that wouldn't start automatically, POST failures on the motherboard, and random GPU errors.
DDR5 remains costly, so I don’t have another unit nearby. However, the RAM is available for the board.
