cpu/dram ratio

could anyone please tell me how i can access the 3:4 cpu/memory multiplier on the 4bdsa2+. I have only got options for auto. ddr200 and ddr266. I am running 23/5/02 bios.


Please help

If you have a 400 cpu (100fsb or a) then the 266 option is the same thing. 200=100mhz memory x2 ddr with cpu at 100fsb 266=133mhz memory or 266ddr with the cpu at 100fsb.

3:4= cpu fsb +33mhz=memory speed so it's the same thing.

thanks for the reply, i'm slowly getting the hang of this. i have set memory to 266, raised fsb to 133 on my p4 1.6a and am running stable at 2.13 ghtz with memory speed of 354mtz.
