Question Broken pin on CPU socket ?

[Theknowlestweet]

So I bought an MSI Z370-A PRO motherboard a few years ago, when I installed it, I managed to fat finger the cpu installation and bent a few pins, I bent them all back and the motherboard worked perfectly for years, then one day started turning itself off.

I found that Ram channel 2 had died (I used 2+4) and whenever ram was placed in that channel the system wouldn’t boot and the CPU and DRAM light would flash on the Mobo, channel 1 also died.

So I was left with only channel 3+4 remaining, both of those worked fine but obviously single channel, so I decided to replace the board with a cheaper one as I wasn’t too fussed about overclocking anyway and didn’t want to risk the rest of the components given the ram clearly had an issue that I had not determined the cause of.

I’ve decided to dig the Mobo out and find out exactly what was wrong with it and I’ve discovered that one of the pins are broken on the CPU socket, however as I said previously, the system worked for years before finally giving up and I had not taken the CPU out at the time since installing it, so I’m certain that I broke the pin when I tried to bend them back but this was probably 5 years ago at this point so I can’t remember.

Anyway I did some digging online trying to find out which pin had broken, but I can only find diagrams with blurry wording so I’ve no idea which pin has broken.

The CPU is an 8600k (coffeelake) if that helps as AFAIK the 1151 socket has multiple variations?

Either way it would be interesting to know whether it is this pin that killed the ram slots, as it wouldn’t make sense for it to run for years then suddenly die like it did if it was a broken pin all along, but as of yet I’m unable to determine what the pin does.

I’ve taken pictures from multiple angles and included a small green line where it is.

Thanks!

It's possible that the CPU's IMC just gave out if you're seeing that the issue with your rams is exhibited on another known working motherboard(with the latest BIOS version). You could try and reflash your BIOS on your current motherboard and see if that helps as a corrupt motherboard can prevent the system from posting.

If you're on an i7-8700K, I'd suggest you sell off the processor and recuperate what you'd spent thus far.

The processor works fine as does the ram as I’ve been using them in another system for over a year now, so it’s definitely the motherboard, I think I’ll have to try reflashing the motherboard next to see if it’s corrupted.

Out of curiosity why do you mention selling the processor to recuperate?

It is pin DDR0_ECC[7].

My assumption here is this is responsible for memory channel 0 (channel 1 on the board)?

If that’s the case this likely won’t be recoverable without soldering on a new socket, something I won’t be attempting.
