DRAM frequency

post #1 of 8
Thread Starter 
I have a Biostar p4m80-m7, and a prescott 524 3.06ghz. Biostar mobo is not overclock friendly, but does allow me to increase the cpu frequency. I have gotten it up to 3.4ghz, and everything runs fine. Problem is there is no way that I can figure out in bios to lower the DRAM (PC-3200 Ultra) frequency to get a 1:1 ration. The bios automatically increase my DRAM frequency as I increase the cpu frequency. So I have a 133 fsb, and ddr2 @ 200 for a no overclock 6:4 ratio. As I increase the cpu so goes the DRAM. So it's always 6:4. Is this a major problem. Is there a way around it that anyone can suggest.

I can play all games OC'd and never have a problem except for BF2 which hates when I oc the CPU, and crashes to desktop. It lets me play with an OC's 6800 gfx card though at least

to change the freq go into advanced chipset features then dram clock/drive control then dram clock and change the value from spd to 133 that should make it run in 1/1 with the cpu

yeh sounds like my asrock motherboard. Should be a dram freq option.

There is an option to set it to 100, 133, 166, or by speed.

you can see it on pg 16 of the bios manual

ftp://ftp.biostar-usa.com/manuals/P4...M80-M7bios.pdf

So if I set it to 133, then try to increase the cpu frequency I am wondering if it will lock at 133 or continue to rise as I increase the cpu frequency to keep that 1:1 ratio.

133 will be the starting point the ram will then rise with the cpu keeping it at 1:1

Ok, a little follow up. I now have a 1:1 Cpu:Ram ratio. I overclocked to 3.4 from 3.06, but running aquamark I noted my CPU benchmark was lower than when I had a 6:4 ram to cpu ratio. So is the stability of the 1:1 ratio outwiegh the performance loss? it's not a big difference aquamark scored my cpu around 7200 originally, and now its 6813.

My gfx card 6800 is around 8500
