Post 55 Error

[ganons]

I have a Maximus VI Impact board and when I gave the stock cooler a decent tightening, I got Post 55 error and PC wouldnt boot. The nearest ram slot to the cooler would be out of action. I did end up getting it to work as apparently the cause was the cooler being too tight. Fast forward to a new cooler (Zalman CNPS8900) and again same problem if reasonably tight, Post 55 error. I had to spread the paste instead of doing a pea application leave the top right screw closest to the ram slot looser than the others. This was a trial error and had to remove the cooler about 15 times or so for the PC to boot and show decent temps. Now that it boots, it would be idle around 32 then fluctuate to 47 then down again. This never happened when I first tested it outside the case, had it decently screwed in, it would be 31 idle without fluctuating.

TLDR; why in the world cant I tighten the cooler like Ive seen others do with the same cooler or board? I spent hours to get it to boot with a decent temp

i find this very hard to understand.

The M6I board should have a backplate behind the CPU which would prevent socket warping.

I dont understand how your getting warping.

I have had this problem happen a very long time ago on waterblocks which required insane mounting pressures.

The result was board would be warped, which would cause error codes all over the place as something was sorted.
Worst case scenario would be it would lift the mosfet sink up so the mosfets under the sink would lose contact and eventually fry from overheat.

But i have never heard of the ram being an issue....


My intial guess is somehow the cpu is skipping a pin under the mount pressure, which is giving you errors, and not the actual ram slot.

You can get errors from bad contact of cpu pins as well, so that may be something to look at.

There is a pin that looks bent maybe, hopefully not snapped. Guess that could be the problem? Gonna have a look at it with a camcorder so I can fully zoom in
