There is a sporadic boot problem involving a DRAM LED.
There is a sporadic boot problem involving a DRAM LED.
7800x3D
32 GB DDR5 6000 MHz G.Skill RAM
Aorus Elite AX b650
Zotac RTX 4080
RM850x
Issue: Occasionally the PC fails to boot and gets stuck on the DRAM LED until manually shutting it down. Once powered back on, everything works fine. Performance is excellent, temperatures are stable, etc. I've only experienced this problem once before—it happens occasionally when the PC is off for a few hours. Even then, it's rare. I've managed to avoid the issue for as long as two weeks or as little as two days.
Steps taken:
- Tested different RAM OC settings, but the problem continues without any changes.
- Ran memtest86, all passes completed successfully.
- Replaced RAM units.
- Installed new RAM modules.
- Updated BIOS on both old and new motherboards (FC, FCd, FB, FA1a).
- Switched to a different motherboard (which included reseating components).
- Contacted Gigabyte support, who advised checking the CPU pins—both original and new boards showed no issues.
My best guess is a power supply concern, but I'm not sure. Any suggestions or information would be greatly appreciated. This has been a really frustrating situation.
Extremely low...
Apologies, I didn’t fully capture those motherboards.
What’s the age of that Corsair RM850x PSU? It seems to have been used heavily for gaming, video editing, or even bit-mining.
Keep in mind that PSUs supply three voltage levels (3, 5, and 12) to different system parts. Any deviation from these could lead to issues.
A possible hint is that the PC/PSU cooled down recently; connections might have loosened or changed. It’s only slightly warmer now, and everything appears fine.
Can we replace it with another known working PSU?
Make sure to use only the cables included with the PSU.
You can test PSUs yourself if you have a multimeter and know how to use it. Or find someone who does.

Out of tolerance voltages raise suspicion about the PSU.
The RM850x comes in brand new condition. My PC operates in an environment with minor temperature changes, typically not exceeding a few degrees Fahrenheit. I’m using a Rm750e model previously (just a couple of months for light tasks), so I’ll connect it to check if the problem continues. The resolution could take between five hours and two weeks. If the issue remains after checking the PSU, what steps should be considered next on the troubleshooting list? Also, regarding your concern about temperature effects, do you think the problem is related to the PSU’s connection? I assume a properly functioning PSU should handle variable temperatures and still boot correctly.
Which G.skill RAM model do you currently use?
My Gaming X AX experienced problems with Ripjaws S5 XMP, including boot and restart difficulties. Various BIOS versions caused different issues, but all led to similar complications. I resolved the problem by installing G.skill Flare X5 EXPO.
The initial RAM configuration was this teamgroup collection.
The updated version is now listed in the QVL for both my original gaming X AX and my current Aorus Elite AX.
A fully operational PSU must handle a wide temperature spectrum; both inside the unit and outside in typical conditions. Review the temperature specifications.
Resolving intermittent issues can be challenging due to several possible causes.
If a replacement unit like the mentioned RM750e fails to fix the issues, consider these possibilities:
1) A fault in the wall outlet.
2) An issue with the motherboard.
In most cases, the wall outlet is more likely to tolerate such problems than the motherboard.
Inspect the power connectors—plugs, wires, and sockets—with a bright light source or magnifying glass.
I made sure to double and triple check that my second set is correct. I’m confident the odds of having two parts with the same unusual problem are very low, so I’d think a mobo or ram issue can’t be the cause.
