Make sure you RAM is set to a 1:1 ration.
Did you increase your RAM voltage?
Thanks zenmaster! I changed my RAM voltage from AUTO to 1.9V (what it says on the memory) and changed the DRAM speed to 1:1. I upped Vcore voltage to 1.38 as well. I can now at 2.2 Ghz. Didn't want to push it at this point because I was afraid the generic power supply I have will ruin my hardware.
What do you think? Can I push it or should I be careful with a generic ATX 450 watt power supply?
According to speedfan,
Core 0 35C
Core 1 35C
Is this relatively stable? Haven't observed any problems yet.
