3770k Memory error 55 after delid

post #1 of 16
Thread Starter 
So I delidded my 3770k yesterday to try and drop my rendering temps (running around 80C for days seemed harsh),
I did it using the vice method and everything seemed to go well. Mounted it back in my system with an h80i I had laying around,
but when I start the system up I get error 55 and the computer crashes, even in the middle of Win8 setup, sometimes it doesnt even boot. I read online that this could be due to bent socket pins (I'm on an Asrock Extreme 4), but after removing the cpu, cleaning it with isopropyl and checking for bent pins and finding none, the system still wont work properly.

So I started removing memory modules, and the system *always* runs fine as long as there is only one stick in slot 3 and 4, i.e. one of them remains empty. As soon as I put a stick in both slot 3 and 4 (seen as 1-2-3-4 from left to right), I get crashes and BSOD. So I'm basically stumped here; is my 3770k messed up? Is there anything else I can try? I have reseated the cpu 4-5 times.. When I booted into windows with only a couple of sticks in the slots I checked RealTemp, and the cpu is running a nice 30C on idle, so it doesnt seem to be a heat issue either.

I also tried loosening the pressure of the h80i pump on the IHS, but it didnt help. I did notice that there was a tiny bit of the pcb chipped in one corner of the cpu, like way out on the edge, nowhere near any connectors, I dont know if it came from my delidding or if it was there from the start, but it seems unlikely to me that it would be the issue.

The problem is that I might need to use my full 32gb of ram later on, and my setup as it is now will not boot with all ram installed..

Any suggestions on further troubleshooting?

Not sure, but you shouldn't be putting the RAM right next to each other If 1-2-3-4 was the layout, use 2 & 4 (I typically avoid 1 because of people's CPU heatsinks can cover it up)

Just a start!

As I tried to explain in my first post, any setup not using 3 & 4 simultaneously work fine. I tried 1-3 and 2-4 and it works perfectly.
But the problem is I have 4 x 8gb, so I need to be able to use all slots

have you tried alternating different ram sticks that you know for sure work?

Restart your computer, let it BSOD, and take a picture of the 00x00000 code. that will help us diagnose the issue.

Have you checked the actual PCB of the Processor, any tiny scratches you may have nicked the memory controller tongue.gif

I've tried what seems to be all iterations of ram setups with my sticks, and I am 99% sure all of them are fine, as they were working just fine before I delidded the cpu.

One of the errors I got was IRQL_NOT_LESS_OR_EQUAL, but there have been plenty of different ones.

Someone else mentioned something about their cpu only running in single channel mode after delidding and chipping a tiny bit off the pcb? Is this possible, and why would the pcb chipped mean anything if there aren't any connectors or leads there?

quite possible

Go to those URL's and Cntrl + F "single channel"

apparently this guy, http://www.overclock.net/u/130164/phobos223 had the single channel error and was able to fix it. PM him smile.gif

Thanks mate, hopefully someone else might pass by this thread with the know-how to (maybe) fix this as well, since the user you linked to hasn't been online for 3 weeks it seems.

I'm 99% sure that you have nicked your 3770k PCB somewhere mate. I have same rig like you, do messed up my 3770k with the razor blade and left a tiny mark on the PCB, as the result RAM slot 1-2 does not even work.

Well, I do tried to see whats wrong with that tiny mark on the PCB, but under x8 microscope, I don't find whats really wrong with it so still looking for a way to fix this thing haha. Forgot to mention, I borrowed my friend's xeon e1230 and 4 RAM slot works fine and that means my 3770k is partly broken mad.gif

A quick update, I re-cleaned my PCB with alcohol and some tissue and 4 RAM slot is working fine now, maybe you wanna try this method too my friend, good luck ^^
