Cpu damage, it this one a gonner?
(1/2) > >>
Refrigerator:
Bought a used cpu and the seller said it had some minor damage.
Yeah right, looks more like this cpu kissed a wall at mach 3.
Looking at the pinout it looks like the damage is around the bclk area and the missing pin happens to be ground.
Gyro:
I think that's a case of a CPU with complete damage - It's a pretty binary thing (no pun intended).

It's not just that pad, it's the de-lamination of the PCB which will probably have broken buried vias and tracks from other pads.

Probably not your wisest purchase.  :-\

Holy crap ir bloody works

I think I'd agree with that sentiment!  ;D

You're lucky, but in general CPUs have a lot of redundancy in their pinout (mostly power/ground) because they need to handle a lot of current; performance at high load may be slightly compromised by that damage. I recall reading an Intel datasheet for a BGA part that even mentioned x% of balls may fail over time with no functional effect.
