Possible to repair a modern Xeon CPU?
« on: February 23, 2017, 03:14:34 pm »
Story short.. Got scammed online, so now I'm left with an empty wallet and a DOA Xeon. My PC will boot with it in the socket, and I can get into the UEFI/BIOS and see the specifications, core count, clock speeds, cache etc. But that's as far as it goes, the PC will restart just after POST (will not boot into the OS, or even start to load it), and when booting from USB/external drive it just freezes.

The CPU is a bit beat up, as you can see in the first picture - nicks, dents and scratches - which devil would do such a thing?!?! Two potential issues after examining the CPU under my crappy USB microscope:

1. Could those traces be torn/open? Anyone know what are are for? Decoupling?
2. Could the pins in my socket not make proper contact with either or those two pads?

How would I even go about fixing something like this? It's tiny, and my crappy microscope is of no help.. Anyone know if the pinout is available for these things?

I wouldn't spend too much time on it. I'd try and repair the big scratches to the LGA contacts with a little solder as they're likely not making proper contact to the socket pins. Hopefully that middle scratch is just skin deep on the substrate.

I picked up a Zeon processor for an LGA771 to LGA775 conversion to breath some life into an old PC.  It's a conversion people have done commonly, but there are some minor differences in the pin-out and wanted to verify there wouldn't be a problem.  I was able to download data sheets from Intel for the LGA771 and LGA775 parts to check pin functions.   A good number of the pins are just power and ground.  Not sure on the newer ones if they post data sheets or not, but it's worth a look.
