The device ceased functioning after using four RAM sticks.
Hey everyone! About a month ago my ASUS TRX40 pro stopped working with four RAM sticks (Corsair Dominator 4x16GB @3200 MHz). All four are fine, but I tested each one separately. My motherboard supports either one or two sticks. If I use four, it shows a C5 error. My PC is five years old and was always working before. I did a BIOS update before the issue started, but I’m not sure if that’s what caused it. Any tips would be great!
It might be a bent pin near the memory controller area. There could also be an empty slot. Have you tested other RAM sticks in each slot? Even if everything functions but four DIMMs aren't recognized, consider reverting the BIOS settings and checking again. If the issue remains, it likely points to board damage.
Hello! Your experience sounds a bit unusual. The issue might not be tied to BIOS but could relate to how your system handles memory under certain conditions, such as using multiple RAM sticks. Would you like advice on checking or adjusting your system settings?
Things became even more unusual. I went back to an older BIOS version, and Win11 stopped loading altogether. I had no option but to switch to the latest BIOS update. Once that was done, everything worked properly. Here’s what I tried: 1. Used just one stick in the A1 slot—PC failed to load, showing a D0 error. 2. Plugged three sticks in quad channel order, except for A1—loaded without issues. 3. Inserted the last stick into a problematic A1 slot, and loading went smoothly. Activating D.O.C.P. made the PC unbootable. Overall, I’m relieved the issue was resolved, though I don’t understand why.

It seems unlikely the issue occurred if the machine remained in one place, conditions stayed consistent, and temperature/humidity stayed steady without any changes to the case. A BIOS update might be responsible, according to Robchill, but confirming this requires reverting to the previous BIOS version and booting Windows as suggested. Verify CSM, TPM, and Secure Boot configurations, as these could prevent Windows from starting. I support Robchill’s advice: update the BIOS, clear CMOS, and ensure Fast Startup is off. Also double-check RAM installation—contact problems with CPU or DIMMs are common on this board.
