Overclocking memory help

post #1 of 2
Thread Starter 
hi i am a newb at overclocking and have been reading many of these threads lately and i am a little confused on how you set your ram to 1:1 operation. for example what would my ram speed be for 300mhz fsb? to have to be running in 1:1. and where would i change this?

thank you.

The means of setting a 1:1 CPU:RAM ratio depends on the exact BIOS on your motherboard. Some board explicitely show the ratio, e.g. 1:1, 2:3, etc. Others have you set a stock RAM speed, and the board takes it from there. For example, your CPU runs at 266 MHz at stock speed. To run at 1:1 on that kind of motherboard, you would select DDR533 in the BIOS (DDR frequency = 2x CPU frequency).

In your example, 300 MHz would not be the FSB of the computer; it would be the external clock speed. FSB = 4x external clock speed, so your FSB would be 1200 MHz. To run at 1:1, your RAM would be at 300 MHz or DDR600 speed.

Just poke around in your BIOS and see what RAM options are available.
