ASRock DeskMini X300 memory slot B1 issue

Hi again,

I spent the whole day assembling and disassembling the the whole system, and I fixed it on the 6th attempt.
It was in fact a slightly slightly bent CPU Pin. If you look on the CPU, the side that faces the memory banks, the outer pins, that was it for me.

I also used a soft toothbrush with alcohol to completely wipe all thermal paste and used magnifying glasses, headlights and macro photos to help in the process.
I also brushed the socket with the toothbrush and alcohol.

Hope you guys have the patience.

You really don't want single channel ram.

In my case it was the X300 DeskMini motherboard which was broken, I swapped the processor and the issue remained.

Have you checked for any bent/missing pins on the CPU? If even a single pin is
missing it could easily account for the faulty/missing B channel. As Threadzipper
mentioned, the IMC is on the CPU. Each channel will have it's own separate path
from the CPU to the motherboard, if one of these is not connected then it explains
the issue.

I used the support and received a very similar answer.

Hi,

I haven't tried that yet, but it is good advice that I will try.
