The only way to get to the desktop is to have the vcore at 1.300 which is the highest voltage available. I have it at 2.37 with no problems, ddr2 667, ht x4.
I have OCZ special ops 2gb ddr2 800, amd athlon 64 x2 4200+ windsor, evga geforce 7600gt Ko, asus m2n4 sli mobo, 300gb hard drive, 400 watt antec power supply.
Oh and i don't think this matters but I just started overclocking my graphics card.
