Setting bios config for ddr & fsb speed

Hi
Anyone know what settings I should make in my bios for the FSB speed and DDR frequency?
I have MSI 745 Sis Ultra motherboard, Athon 1.8 xp and 256 333DDR ram.
The FSB and DDR frequency are linked by a ratio - the FSB speed goes up to 200 and if I change the ratio between them I can get DDR frequency of 320
Should I set it to this and shouldn't the DDR go up to 333 as it's what the ram should run at?

its called Double Data Rate because it will run at double the speed that you set 133=266 166=333 setting the FSB at 133 means the chip runs at 266 which is what XP's run at and with that setting the DDR should read 166 running at 333
someone correct me if I'm wrong

Depends on your bios. Set FSB to 133 and set ddr to auto or turbo.And latancy to whatever is on your ram probably 2.0 or 2.5. Mine has a sticker on it that says 2.5 but mine is pc 2100 or 266 so yours may be 2.0

I will try that, then my cpu speed should read 1.5x instead of 1.1x.
Although my bios thinks it's a mobile processor for some reason, not xp...

I've set those, but windows still says it's running at 1.15ghz instead of 1.5 and it says it's a 'mobile AMD 4' not Athlon xp!?
