Overclocking RAM

[NobiPintoe]

hi everybody

i have some corsair xms pro that is guaranteed to overclock to 500 mhz.

how would i go about overclocking it? i looked in the bios, and it said it was at 200 mhz (even thought it is pc3200 (400 mhz).

if i overclock the memory to 500 mhz, do i have to overclock the front side bus also? and what would i set the ram to? 240 mhz? 260 mhz?

thanks for your time.

The reason the BIOS says its at 200mhz is because its in dual channel. If you overclocked the memory to 500mhz it wouldn't increase the speed because the FSB is still set at 200mhz. Therefor, you have to set the FSB at 250mhz to fully utilize 500mhz memory.

i dont have dual channel capability.

What make/model is your motherboard?

it says 200 in the BIOS cause it 2x the speed hence DOUBLE DATA RATE (DDR) in the ram...so 200x2 = 400 if you wanted it to 500 you'd have to put your CPU FSB up to 250 and also get your RAM frequency up to the same.

all motherboards that support DDR400 will also support a CPU with:
333MHZ or 400MHZ if it is socket A
400, 533 or 800MHZ if it is socket 478
800MHZ if it is socket 775 (otherwise known as Socket T)
800 or 1600MHZ if it is socket 754, 940 or 939

if you have a socket A motherboard, you will not be able to use the 500MHZ speed even if it is overclocked to that, as the CPU will be bottlenecking it
all other sockets you should be fine - most socket 478 boards run at 533 or 800MHZ

to overclock the RAM to 500MHZ, overclock from 200MHZ to 250MHZ so that 250x2=500MHZ
