This is what you are going to do:
RAM timings 5-5-5-15, 2.3v
Memory multipler 2.00
raise vMCH (NB) to the max (yes, this is safe)
raise vFSB a couple notches
Dont use Easytune... Clockgen in any case to extract up to the last Mhz.
problem is in my bios i cant see anywhere i can change memory timings.
but i am looking into buying some Geil Ultra ddr2 6400 with 4,4,4,12 timings in the new year.
