Yes, /GL "etc" the etc are all the other required options - all the messages rec'd indicated it appeared to work. In addition, there was huge increase in NPS , matching the NPS your original crafty 64 exe provided on my machine. > >(2) Output that you provided says "System is SMP, not NUMA". When I start Carfty >of Windows Server on AMD64 it correctly recognizes it as NUMA. I am not sure I'm running Win XP 64, I think that is the same as Windows Server 64? I am not sure. I'm not sure what the issue is - it could be bios related , although current bios is dated 4/04 - there appears to be no further update. I am not very happy with the MSI motherboard - in hindsight, I strongly recommend Tyan for the Opteron only for alot of different reasons. (ask me if anyone needs more on that) I see no way to turn on NUMA in the bios. Eugene, you have been a tremdous help here and I appreciate all your feedback immensely. Thanks, Michael who >is guilty here -- Windows XP or BIOS settings. If later than there should be a >way to turn NUMA support on. > >Thanks, >Eugene
