I have a gigabyte x48 DS5 mobo, Q9400 OC to 3.4ghz which seems stable w/vcore at roughly 1.3. I have 8gb OCZ ddr2 1066 platinum ram which is running in 2.00A which puts it at 830 mhz I think. timings are 4-5-5-15. ram voltage is around 1.8. Everything seems to run fine until a run Prime 95 and it freezes up my whole PC. I'm def a noob to OC'ing andf any advice would be great. I'd like to get my ram running faster but I dont want to fry anything. Ive also heard tighter timings are better than higher mhz, dont know how true that is. Any and all advice will be appreciated. Also I have an Enzotech Xtreme CPU cooler which kicks ass and have never seen my temps go over 50 degrees so temp is not an issue.
