No I did mean cores.

Can't remember the guys name now Phil Taylor maybe?? was saying when the patch came out it could theoretically use that many.
I don't know anyone who would however!

But still it's all limited by core0.

EDIT Here is the quote.

"As far as practical limits on number of usable cores; currently SetThreadAffinityMask only allows explicit scheduling of threads on 32 cores ( the mask is a dword ) on Win32. So thats our effective limit on number of cores. But as soon as there is a way to explicitly schedule them, we can handle 256 cores."  

It probably adds more confusion than anything.  ;)
Also I think it would be a Microsoft requirement to have to use Windows Server to access >32??

Mark try running task manager on top when you are loading into a new location, you should see it light up then. Are you running with HT off?
