2.4C overclocking on p4p800-Deluxe

K, well i've been able to get my system stable at 3.2 with 267 fsb and 1.6vcore... I've got the cpu to hit 3.4 and let me log into windows but it wasn't stable when i ram prime95... i've got the ram going at 5:4 but i can't figure out how to change the timings and set it to performance mode... they r running at 2.5, 4, 4, 8 thats wat cpu-z tells me... i'm sure i can get the ram going tighter then this its ocz pc3500 gold edition and should be able to handle a bit tighter timings... just need to know where to put the timings in... I'm running the bios version 1014.005

in ur bios, goto Advance, under Chipset you would see "Configure DRAM Timing by SPD" Choose the Manual option, this will let u configure ur timings manually
