I configured an older socket 939 SLI board today with an 8600GT and an 8400GS. Unfortunately, according to procexp, the two are using the same core of an Opteron and it's really slowed the 8600. One of the Opteron's cores is at 100% utilization and the other is at 0%. Both of my GPU2 clients are configured to NOT lock to a specific core. I assumed that meant that both CPU cores would be utilized as necessary, but that does not appear to be the case.
Can somone clear this up for me please? And how would I force/allow the other core to be used?
