My first AMD Opteron engineering sample on socket 940. Does it work? No idea, I have no ways of testing it and assembling a system for only one CPU is a bit expensive for my taste .

This particular engineering sample has no information grooved into the heatspreader but rather like it's stamped on. As seen on the pictures this method is not very durable as the paint falls off. For those who want to know what was on the heatspreader:

Engineering Sample

There is not much information on the internet about this CPU. Unfortunatly I don't know the production date which makes it difficult to put it in a time frame. I suspect this is quite an early sample. The introduction of this CPU was in December 2004.

Based on the packaging of this CPU I think this is a 90nm model. The 130nm models used a ceramic packaging.
