Unknow type of CPU

[Tommmic]

Hello, I need help with this CPU . This is gold Top or not? What type is it? I never see this cpu before and I have 3,5kg (7 ounces) of them. They have any gold? Thank You for Help!

Looks like a Fariday CPU. That should be a copper plate on the top and chances are the plating is gold.

Thanks for answer. Someone else maybe know something?

They look like the AMD Athlon's as far as the top heat spreaders are concerned but your
chips are pinless. Look up the part number on the chips that starts with M8C..... and see
what kind of chip they are. The MFG's logo kind of looks like the F in Fujitsu's logo.

That's what it was I could get the name out of my head. Thank's.

Or why not just break one open to see how it is constructed.

On the pictures it looks like a thick gold plated heat spreader on a glass fiber board with some surface mount capacitors and resistors. Based on that I would suspect a flip chip mounted die soldered onto the heat spreader with indium solder, just as pinless P4 chips are. The most of the gold is contained in the plated heat spreader so that should be simple enough to get an approximation of gold content by using simple math or one of the gold plating calculators floating around, for example the one on Sam's website http://www.goldnscrap.com/index.php/calculators

But that's only a guess...
