Damaged CPU - i7 2700K

Hey folks,

Have you guys ever run across a CPU that still technically "works" but is super damaged?? I recently bought an i7 2700K off eBay and it is missing like 5 caps. I am returning it (seller is agreeing to refund it, had no idea it was missing caps) but I am curious if anyone has ever ran one of these and had any luck. I have actually had very good luck unbending pins on AMD CPUs but obviously this is a whole different matter. Send me pics of messed up CPUs you have had luck with.

Never had this situation. I've only ever had missing pins on S939 CPUs and crushed sockets for Intel that still worked.

Not with a cpu, but on the vrm area of a itx motherboard it was missing a few smd capacitors. Still worked normally for the time I had it. You can always just solder them back on if you know the value.

That 2700K still works? Haven't seen that before. I have seen where a 980X randomly lost half its cores. It only had 3 cores plus HT so 6 threads instead of 12. We tested other i7s and other boards to verify it was the CPU and not the board. Very strange.

I'd buy 1 of those to fix, those caps are plenty big enough for me to work on. Plenty of smaller stuff on PC parts that I'd mess up for sure though.

I have an embarrassing story about when i first tried to delid my 4790k i did not use the vice only method, but clamp the CPU in the vice and try with a piece of wood and hammer.

But accidentally i did not hold the wood piece good, so i struck it with a hammer and it rubbed over the "bottom" side of my 4790k knocking down many of those caps or small metal things.

After this i successfully delidded it with the vice only method, then put it into a motherboard to test. I did this without IHS and i forgot to turn it off until i saw a tiny bit of smoke coming from the die.

This same CPU is still running 1.425v 4.7GHZ (Bad OCer) for 2-3 years now. So somehow these little processors are tougher then most think.

If you try to run it just use some Memtest and or other CPU stability testing to verify it working 100%.
