OC'ing pc-6400 on msi k9n sli platinum

[MrMeikel]

Hi,

x2 3800 AM2
msi k9n sli platinum
7900gtx
2x 1gb Corsair XMS DDR2 PC-6400 (800mhz) 5-5-5-12

I am attempting to overclock my system (new to CPU/RAM oc'ing), but have found that the only memclock speeds available in the bios are 400, 533, etc, 800... does this mean I am unable to overclock my RAM at all? Would upping the HT(T) Multiplier affect the mem speed?

 

[MrMeikel]

anyone got any thoughts on this?

they're actually ratios...

400mhz = 1:1
533mhz = 4:3
667mhz = 5:3
800mhz = 2:1

the memory speed is cpu/x, where x = ceiling(cpu multi / memory ratio)
