My ram only works in slots a2 and b2 in single channel
If i try to every other configuration system doesn ť start.
A single stick doesn ť work in both A1 and b1 slot. So I can ť use dual channel memory
I tried cmos reset, reseated cpu and watched for bent pins(didn t find any) on socket.
Tried different voltage and frequencies for ram and xmp profile active and non active.
Tried loosening cpu cooler too.

Do you see any bent pin iin this image?

Now the factory one after I removed the battery and tried reset. But I tried upgrading the bios too to latest version(1.50 if I recall right)

Solved.
I reinstalled everything and it was a screw under the mother board, it was probably preventing it on being perfectly stable and not flexed.

Who would have guessed that?

A screw shorting the board to the case. The screws was probably in the area of the RAM or CPU and it was touching a thing related to the RAM and that was causing a short probably and messing everything up.
