Hey folks, I'm facing a pretty strange issue with my PC. I built it back in 2022 and it's been running smoothly until recently. After a brownout a few weeks ago, my PC started having problems. I noticed it going through a boot loop, flashing red CPU and yellow DRAM lights. At first, it took several tries to boot, but now it just refuses to post with more than one stick of DDR5 RAM. I can only get it to boot with one stick in slot 4. If I try to use two sticks in slots 2 and 4, it gives me a memory configuration error. I've reseated the CPU, checked for any damage, and swapped RAM around with no luck. I even tried adjusting the DRAM voltage but that didn't do anything. I'm really hoping my motherboard didn't get fried in that first power outage. Any ideas on what could be causing this?

It sounds like there might be an issue with the RAM channels on your motherboard. If your sticks work in slots 3 and 4 but not in 1 and 2, it suggests that channel A could have failed. That's usually indicative of a problem with either the memory controller in the CPU or the motherboard itself. Have you checked the motherboard manual for optimal configuration? Sometimes it requires specific slot arrangements for dual-channel mode. If it's still not working, you might need to consider replacing the motherboard or CPU.
If your single sticks work fine individually but two sticks don’t in the correct slots, then it’s likely something's up with your motherboard or CPU. Have you tried disabling XMP in the BIOS to see if that changes anything? Running the RAM at default speeds can sometimes resolve these types of issues. If that still doesn't work, testing your RAM sticks in another PC, or using new ones in yours could help narrow down the problem.
