PCeye hes talking about AM2, the link you gave is for 939!
There are 4 X2 3800 AM2s

And 3 single core 3800 AM2s

For some reason 3800+ seems to stick as 939 here unfortunately. The best information on any AMD model seen is simply found by going direct to AMD's own reference chart like these seen here and choosing the model or socket type first. You can review the specifics for a specific model there. http://products.amd.com/en-us/DesktopCPUFilter.aspx
He already know what he has and the AMD link, look at post 21! Why do you keep talking about 939s and Semprons
