Code 55 after changing the CPU Cooler.

[neverblink]

Hello.

I just assembled my new rig yesterday. The only problem I had then was my CPU was running unusually hot. I remounted My H100i and the no avail. I then switched to my Noctua nh-u14s. I tryed to boot and Code 55 appeared. I tried using different RAM and nothing changed. The only thing that gets my comp to boot now is moving 1 stick of RAM at either outer dimm slots.

I took a look at the pins in the CPU socket and nothing seemed to be out of place after inspecting it with a Magnifying glass.

Does anyone have any idea what could be the culprit?

Press ram.

RAM is installed correctly. I've tried 3 different sets of RAM. aswell tried memOK

The system ran perfectly before I switched coolers. I've tried to even out the pressure on the cpu as well.

Sounds like uneven pressure. Remount the cooler. If in doubt, test with the stock heatsink.

I've remounted cooler 5 times. Tried stock heatsink. None of that worked.
