I just bought a Q9650, mas in in my Win764Bits i just see 2cores.
Verified Taskman(2Cores),CPU-Z(2Cores),BIOS up to date (P5QPremium), CMOS cleaned, tested another S.O. and nothing. i sill seem only 2Cores
I've played around with msconfig to disable cores. When cores are disabled, it will only list the number of cores that were previously enabled. For example, if you have disabled 2 cores, that drop down list will only show 2 cores, not 4 just like in your picture. You have to uncheck the "Number of Processors" box to get all four cores back.
Can you verify that when you have unchecked the box in msconfig that you are still seeing only 2 cores?
