Hello, unfortunately my QYFS broke yesterday (post code 29 no matter how I plug the ram sticks). I want to share a couple details here. A while ago my pump died. Until I realized, I tried to boot a couple times with crashes, in the third attempt it froze at windows load screen. However the computer was on, and the cpu was super hot to the touch. I think something broke at this point. When I got a new pump I was not able to use all my 4 ram sticks, only 3 (otherwise code 29). Also only the right-side slots seemed to be working and my nvme was not detected at one of the slots. But hey... it still worked with 25% less ram so... it was not the end of the world for me.
I forgot about this incident for a while, but the other day I decided to try again to add the 4th stick. Same code 29. Then I thought that maybe I could revert to an older bios (506) and try. So after flashing it seemed to post but also it was impossible to get the 4th stick to work. When I was about to claudicate and flash back to latest bios (1502, I was using this normally before with 3 sticks), to my surprise I was not able to even enter bios. At some point in my posts, I think while memory training, the CPU broke. In the process something went wrong and I ended with all of my ram slots unusable.
FYI, I was using 5600MT/s sticks. I have weird theories about the CPU disabling memory channels with fuses after multiple memory training failures, or simply I fried the mem controller due to the 5600 ram, no idea.
Right now I'm looking into a replacement. Can I get some recommendation?
Tx.
