Question 2nd hand CPU mobo and ram, only one ram stick works at a time.

[Kabe1]

I bought a new mobo CPU and ram of my friend yesterday and have been having some trouble with the ram.

CPU: i5 8400
Ram: 2x4 T-Force Dark DDR4 3000
Mobo: Gigabyte b360m hd3
GPU: GTX 760 2gb
PSU: 750w

My PC will only boot with ram stick in, in the first channel. My mobo only has 2 dimm slots, each its own channel.

I have changed XMP in the bios from disabled to profile 1 with all default settings.

Updated bios to newest version, done a cmos battery reset.

Reseated CPU

Both of the ram sticks are functional, and I saw the PC working with a different PSU and GPU a week ago.

If I only put one stick in first channel I can fully boot into Windows and everything works fine and have tested this with both sticks, they both work fine individually.

Been testing for multiple hours, cannot find the issue please help (

Check cpu socket for bent pins.

I think that could be the issue, in the bottom left you can see one of the pins is a bit off compared to the other ones.

What's my game plan, do I try to bend it back?

Watch some videos, how to do that first.
It requires a lot of patience and steady hands.

Will say that's one thing about AMD CPUs I think I like vs Intel. Since all pins are on the CPU. So usually it's pretty hard to install the CPU wrong.
