Day of defeat source probs w/opteron 165

[aphex]

I just got my opteron yesterday and its 12 hour prime stable at [email protected]. I get very good framerates but after about 20-30mins it just freezes. It freezes for a few seconds when I just join a game too. Any ideas whats wrong?

Rest of my spec:

Opteron 165 [email protected]
1gb Geil Value
DFI Ultra D
Gainward 7800GT 454/1150
Enermax Liberty 500W
