Gary, I would sure give it a try. You can get some permetex at an autoparts store. That's used to make head gaskets for cars. It looks exactly like what Intel uses. And Solar is right, I've seen several on OCN say they RMA'd a delided CPU.

They will rma delided ones ... Gary, exactly how did you do the delid?

A single edge razor blade.

Permatex won't re-attach the severed wires or separate the ones that are touching.

No, but it will put the IHS back on and look just like Intel's job.

Without numbers on the IHS, I can't start a RMA. The box numbers won't work. Clicking a link on Intel's site for info got me an error saying the service isn't available, 404.

I destroyed the 3770, the die was fine, put it together and hung with no POST with the RAM LED staying on. Tried another CPU and it worked fine.
Examining the delidded 3770K I saw a gouge in the PCB with copper showing through. The corner of my razor blade cut into it and cut or grounded out several of the tiny copper traces embedded in the PCB. Can't take a pic, the area is about 0.2mm or less but I can clearly see the copper traces under magnification.

Dammit!

Looking back, the gouge is visible in the original pic.

You're a brave man Gary especially with the luck you've been having lately
As Paul said, Gutted for ya mate.

If you plan on doing it again, maybe leave the lapping untill you know if it works or not.

Thanks Paul and Ryan, I was a dumb ass for trying it in the first place. Fortunately it was a used one I got for $150 so not out $340 anyway.
Steve gave me a number to call and check on RAM with Intel.

Ah thats not too bad a loss then is it chap. I take it you won't be trying it again?

Yes Ryan, I think I'll leave them alone.



Maybe.

Did you happen to get a pic right after you pried the lid off ? Love to actually see what Intel has under there, the condition and amount of the paste, or lack of.
