P55-UD6 socket burn

[So_BAD]

Did you also talke pictures before you had fitted the CPU ? were there no marks on it already ? or doesn't Intel pretest these CPU's beforehand... c'mon lads move on... The issue has been discovered and analysed, with thanks to Massman, SF3D and Raju. It should be corrected in the current range of mobo's...

No, I didn't.

But, I have had dozens of Intel CPU (775, 1366) and don't saw this marks before. If Pretest or not, I don't know. But no marks are visualized before.

By the way, double marks in contacts, is not caused by two pins contacting the same electrical contact into CPU, like a afraid. It makes when the pins is bended over fit pressure (probably).

I "discover" it right now, because a tooke some HIRES MACRO pics of older PentiumD 915 and Pentium4 531, both 775. And in this are the same marks (double contact) and also, NO CONTACT MARKS IN SOME CPU CONTACTS...
(I will upload this pics ans post here latter)

But these CPU is perfect working for many years... any troubel is detected...

Well, I've more confused now....


P.S.: sorry my poor, very poor english...
