Setting RAM speeds

[JCDenton]

My RAM is running at 200 mhz with the BIOS Defaults. How exactly do I make it run at its max speed? It is PC-3200, what speed is my ram supposed to be running at? I OCed my FSB from 200 to 220 but I don't think 200 is stock for PC-3200. Shouldn't it be 400 mhz?

Thanks.

PC3200 ram runs at a stock speed of 200MHz. Since DDR is Double Data Rate memory it is 400MHz.

The RAM runs at 200MHz. However, DDR RAM transmits data on the rising and falling edge of the signal. Thus it effectively operates at 400MHz.

The PC3200 refers to the total maximum theoretical bandwidth - which is 3,200MB/second (3.2GB/s).

so what the fudge is mem timing for?
