[gentoo-user] [off topic] Opteron CPU missing chips on the bottom

[Taiidan]

I purchased a used g34 opteron off of fleabay (sold as working with no 
mention of this) and I noticed that it is missing some of the bits on 
the bottom and that most of them are crooked, I haven't tried it in my 
system yet and I am wondering should return it? or if there isn't any 
much risk of it damaging my (expensive kgpe-d16) motherboard and I 
should see if it works?

Igot it for half the usual price....guess I should have asked for photos.

I noticed many CPU's sold on ebay have this issue (in those cases they 
mentioned it) but I can't understand how it happens, for instance I 
noticed a 6386 for sale where they mentioned that it was missing a few 
and because of that it doesn't work in a dual socket configuration.

Do you mean the pins that mate with the socket?

Send it back! Don't even touch it. Any attempt to straighten a pin will snap 
it off, as like as not.

Sometimes a CPU chip comes out faulty in the specific respect that it can't 
operate in SMP, so those pins are removed and the chip is sold as a 
monoprocessor.

Not the pins (which on socket g34 are on the motherboard)

It is the little IC components on the bottom of the CPU.

You should return it, most of those components are decoupling
capacitors. Quickly switching power produces high frequency noise that
can migrate to other parts of the circuit and cause spurious logic
errors.

It probably plugs in and turns on but I would not accept such a part.
