Well after a bunch of problems over the past month with various parts, I finally got my system up and running.
I just popped in my new G.Skill F1-4000USU2-2GBHZ (2x1GB PC4000) ram and started to OC a little.
I *think* my limit on this cpu is 2.6GHz, I haven't pushed the vcore much though.
My goal is 2.75 GHz with the ram 1:1. I have seen this ram do 275MHz at the timings I am using now .... so hopefully the cpu can manage.
I haven't even started with the 7800, I don't even know what the stock settings are on this thing.
