Can you please post If your CPU supports CMPXCHG16b?
I nave a Intel E7500 SLB9Z which doesn't.
This topic is for those who are interested in upgrading and don't know which 775, 939 or any other socket processor is good for them. I bought on eBay an e7600 cause I'm limited by the 1066 fsb of the motherboa. I will post again when I receive it.
If anyone has any suggestions regarding the content of this topic, please go ahead

Intel introduced the CMPXCHG16B (aka cx16) instruction first with the P4 Prescott/Pentium D and then added it to the P6 derivative CPUs with the Core 2 Duo. Your E7500 should have the instruction.

AMD added the instruction to Bulldozer, Jaguar, and later CPU cores.
