memory timings?

post #1 of 6
Thread Starter 
hey guys i ran prime95 to test my new settings with my over clock and i changed the ram timings down to what they said they were on the sticks' i got a total of 8GB and it consist of 2x2GB ADATA (9-9-9-24,1.55v-1.75v) with 1x4GB Corsair (9-9-9-24, 1.5V) i have them running in my BIOS at 1600MHz @1.52v.

and for some reason my ram was 11-11-11-29, volts were auto,bottom right in pic

With mixed RAM the BIOS will try to set the RAM at something safe in hopes it will boot. If you want to play with RAM timing s for fun, that's cool but there's no tangible gain in system performance with DDR3 RAM by changing the latencies or frequency because they are not a system bottleneck. As long as everything is stable at 9-9-9-24 @ 1.52v I'd leave it there.

1T vs 2T is the Command Rate timing. It means 1 cycle or 2 cycles. 1T (cycle), is faster but hardly even noticable in most systems. 2T is often used with high frequency RAM to allow more time before the command is executed or else an error can occur. Read the link below for more info.
