Is there something wrong with my CPU contacts?

[Newblesse Obblige]

I don't know how to check if my CPU is broken or not because the dual channel doesn't work after my PSU swap(with reapplication of thermal paste on my CPU). Is there something wrong my CPU or it is just the RAM slot gone bad?

No. Share your system details, if you want help. Culprit is most likely your motherboard.

The contacts look fine. Have you checked the socket itself for damaged pins? Usually, if there's a problem, it's that rather than the CPU itself.

A new problem has occur after I reseated(?) the CPU. only one pair of stick works when it both of it worked together before the PSU. It seems other pair is dead.
