I've been trying like hell to get my opteron165 stable at 2.6. I have a dfi nf4 ultra d, 2gb g.skill ddr500 ram, Enermax Liberty 500w. I've tried upping the voltage to just under 1.5v and she won't do prime for more than 3 minutes. One core usually peters out first. Any help would be greatly appreciated. These are my settings:
