I have a few Opterons which have this issue and it seems to pretty common. I assume that some "expert" put the CPU on a table before mounting it, and they move it one the table - can't imaging how people manage to chop off the chips otherwise. While some of these damaged CPUs seem to work just fine, I had several which do not recognize more than 1-2 pcs of memory and, thus, would not recommend buying one of these.

Cheers, Daniel
