So I installed my new chips into slots 1 and 2 it wouldn't boot, I tried one and a time and it did work.
I tried them in slots 3 and 4 and they booted.
It booted into windows at the rated 275MHZ no problem with a HTT multi of 3 and CPU multi of 8.
When I run games on high res or 3DMark05 and 03 it stutters. Meaning it freezes for a split second then keeps going then freezes then keeps going.
I've checked temperatures with an infrared thermometer so that's okay.
Is it the voltage?
I have the voltage at normal, what should it be set to do you think?
