First download , the EXTRENE Tuning Utility. That will walk you through the settings for your RAM and CPU and alot of other things , Be careful wrong settings can make a door stop.
Ok I tweaked my memory settings to Memory Multiplier = 18,66 then it givs me 1866MHz. I also increased *shivering* the Memory Voltage to 1.65v since the datasheet says my mem runs at that...
Hope I'm right in what I'm doing ... else please let me know .. thanks!
