I can't seem to OC my memory even 1 mhz, and if i try the computer just wont boot. I have Corsair twin2x2048-6400 memory and a ds3 mobo. right now i have 4-4-4-12 timings at 800mhz stable and +.3v, but i try to go over 400 mhz fsb and the computer just wont boot. I loosened the timings to 5-5-5-15, and upped the mem voltage to +.5 and I still can't get over 400 mhz fsb. It seems as if the memory just wont work over its stock 800 mhz. any ideas on what i can do? I have the F9 bios for the ds3 as well.
 
upped the mem voltage to +.5

TOO MUCH !!!!! as strange as it sounds too much memory voltage can limit overclock ability of some memory chips.

Have you tried the looser timings at like +.35 +.375?

I think I have the same stuff and see my sig. I would not go above +.4 (2.2 Vmem) on that memory imo.

( I am sure a bunch of people have put 120 VAC to their memory modules and ripped holes in the space-time fabric with the memory overclock, the above is just my opinion based on safe long term operating conditions. Its your stuff, do what you want. )

And it seems silly but are you dead certain you have them in the correct memory slots ?

Also try setting the timings to SPD and see what happens.
 
hoppeler- i know where it is and all, there just isnt a setting so the fsb is higher then the mem speed, its either 1:1 or higher.

billparish- yes i've tried just about every voltage setting up to +.5v and no go. and ive tried lossening the timings to 6-6-6-18 with all the voltage settings and still nothing. i normally dont keep the voltage above +.3 but i tried to push it up to see if it helped at all. and yea the mem is in slots 1 and 3, reseated them and all. i dont think theres a setting for spd in the ds3 bios
