I am running windows 7 64 ultimate. I have ASUS p5q pro, with 4 year old intel dual core2 3ghz. i have 4x 2gig sticks of ancient OCZ PC2 8500 DDR2 (says on it 5-5-5@2.2v) My freind had all 4 gigs running on ntfs setting but it kept corrupting files and had kernal driver crashes for my nvidea EN GTX260. I reformated as FAT32 heardd it should help errors. wouldn't boot though so i removed ram from slot 2 and 4 an was then able to boot and install windows. I've gotten all up to date drives from motherboard to chip to video card, im runnning sixengine, asus smart doctor, and pc probe2, I let smartdoctor and sixengine calibrate my bios and everything works great! except that im only running 4gigs at 800mhz. when i insert my other 4 gigs everythings goes to *** also how to I get my motherboard/chip/ram running at 1066mhz? as i thought thats what i bought... FML please help lol ai tweaker is sooo confusing
