"Heres what we know. The core is bigger than that of the Tbird. It's NOT labeled. It's not socket 370 and its not socket 462. So what motherboard will this go in? It sure does look like the Tbird and Durons packaging but it does NOT have any L1, L2 L3 or L whatever bridges. So I'm asking you guys not only what this CPU is and what mobo to stick it in."
Looks like a K6 or K6-2 to me.....
