Hello, I recently got this mb, the previous owner has put the cpu in the socket with the notch on the wrong side, the cpu has 3 missing pins: AL 3, AF 4, AJ 24 despite of this the cpu boots fine but the problem is that something on the mb must have been damaged because if I start the pc with 2 sticks of ram in the same color memory slots it doesn't boot, the post card hangs on d5 d4 post codes, while if I use just one memory slot doesn't matter which the pc boots fine, it boots fine even if I use one yellow slot and one orange slot. The memory is confirmed working, because I tested it on another pc, while the memory installed when I received the pc seems to be fried. I also tried another am2+ cpu and it gives the same issue.
So far my testing showed that memory slot 1 and 3 are working while 2 and 4 aren't.

Is there anything I could do?

Thanks.
