P4P800 FSB/MEM divider?

[Challenger]

Does this board have one in the BIOS? TIA

 

[Budman]

yes it does.

DDR266 = 3:2
DDR320 = 5:4
DDR400 = 1:1


When at 200fsb.

So those are all of the options? I can't clock my memory past what the FSB is set to?

That is correct. 1:1 is the best you can do with this board. I think it's the same way for all the other 875/865 boards too. The memory controller doesn't support running the RAM faster than the FSB, only synchronous or slower.

But of course you can increase the fsb!!!

Incresing the fsb bring the mem along with it,if you use DDR266 (133mhz) and you set you fsb to 250 then you mem would go up to 166mhz,that's just an example but you get my drift. 🙂

So is there an app like CPUz that will tell me what my memory is running at?

for B chips it has a +4:5 mem ratio below 200fsb.

This is a 2.4c @3ghz with Mushkin Basic Green PC2700 with the bios RAM setting at "320"
