Did you experience a sudden RAM problem after updating the GPU?
Did you experience a sudden RAM problem after updating the GPU?
Following the recent GPU replacement just a few hours ago, my PC only started once and then froze shortly after all auto-start applications loaded. The only changes I made were updating the GPU and replacing the 12VHPWR PCIe cables required for the 4070 Ti. After rebooting, it entered Q-error code 15 for a brief moment before switching to C5, which points to RAM problems. According to the manual, the RAM slots are labeled A1-A2, B1-B2 from left to right. For dual-channel performance, using slots A2 and B2 is recommended. Now my system only boots correctly when I have a single stick of RAM in slot A2; inserting it elsewhere triggers a C5 error. I've tried both sticks, but they function the same way. I’m not using an EXPO or XMP profile since my BIOS only supports a single EXPO setting for this RAM configuration, which caused file corruption and a BSOD when attempted.
Hardware details:
- Motherboard: Asus B650E-E, updated to latest BIOS
- CPU: Ryzen 7800X3D
- RAM: Corsair VENGEANCE RGB DDR5 32GB (2x16GB), 6000MHz CL30 (currently runs at 4800MHz)
- Power Supply: Corsair HX1000i 1000W ATX 3.0
- Operating System: Windows 10
Could it be that the RAM suddenly stopped working as a package or that I inadvertently affected the CPU memory controller? I don’t have a second AM5 CPP or another DDR5 RAM unit to test for faults.

Are you using this motherboard? Which BIOS version are you running? Have you recently updated it and cleared the CMOS after confirming the flash?
I was using version 2414 when it occurred.
The latest update is 3024, which I am currently running.
Changing the BIOS and resetting the CMOS were some of the initial steps I took.
I found out that whenever I reset the CMOS, the PC always restarts with both drives connected and then freezes after a few minutes. Once I switched back to Q C5 using both drives, everything worked properly with just one drive in A2.
My CMOS battery functions properly. This isn't related to a CMOS problem.
My BIOS never experienced any DFE fault issues. This isn't a BIOS configuration problem.
I upgraded from a 3060 and am using the cable that came with the PSU. This suggests the issue isn't due to a weak PSU or incorrect cable.
The problem likely lies with the MB RAM slots, the MB bus, or the Memory Controller that used to be on the MB but is now on the CPU.
