De-lidded 3770K Error 55

post #1 of 7
Thread Starter 
I've had this chip for a couple months now and have run all kinds of stress tests on it. Today I was running Prime95 when the system shutdown and rebooted showing error 55 on the LED. It would only boot with 1 stick of RAM in the second black dimm slot (B1). I played with the pressure on the H100i for a few minutes until it booted with both sticks. Aida64 has been running for a while now so fingers-crossed all is well. I can't really afford a new chip right now so I really hope this holds up. I'd hate to have to buy a new one.

I kept pushing my 3930k under alot of stress test before and I had a similar incident when running prime my computer would restart and wouldnt even post. I ended up messing up my motherboard and cpu so stressing the cpu that much can cause your cpu to fail so be warned

Same kind of thing happened to me after I delidded. I could only run single channel so I reseated and everything worked fine again. It was most likely the pressure/how it was seated.

If it was simply the pressure, why did it take 2 months to cause a problem? I haven't touched the cooler since I installed it.

Your H100 has a pump on top of the seat which sits on the CPU causing slight vibration and movement of the IHS which caused a slight pressure change which was clearly enough to cause the error.

I think L36 was right. I pulled the cooler off and noticed the IHS was slightly crooked so I pulled the chip out, replaced the Liquid Pro on the die and stuck the IHS back on using some Sekisui #5760 Thermal Tape. It's incredibly thin but strong. No more error 55. I guess the H100i pump was moving the IHS bit by bit over time
