P4P800 memory will ony run 3:4 to the FSB

[therealmitchmoyars]

Ok I have a problem that is killing me. I have a P4P800 and I'm running a 2Ghz P4 (400fsb version) I'm running PC2100 in it for now and just was fooling around with it. I poped open CPU-Z and noticed something odd. The motherboard is running the Ram at 3:4 ratio to the FSB. I set the FSB to 110Mhz and it's running the ram at 147Mhz. So I went back into the Bios to currect this issue but the only setting for the DRAM frequency is Auto or 266(since it's DDR266 this makes sence) Now no matter what I set this to(266 or auto) it runs the ram at a 3:4 ratio to the fsb??? I can't get the ram to run at a 1:1 ratio... I've tried 3 bios revsion now and none of them work. Does anyone have a clue as to why the ram isn't running at a 1:1 ratio to the fsb?

In order to run 1:1 with a p4c processor, you need PC3200 or greater. PC2100 is too slow.

No you don't understand. This is an older 2Ghz with the 400fsb(100 in reality) not hte "C" version with the 800fsb. It's running the ram faster than the FSB. Not slower. It won't run at 1:1.v NO matter what I do it won't run 1:1. Single or dual channel mode it does that same. It keeps trying to run the ram faster than the FSB. 4:3 ratio. Where in hte bios can I change the ram fsb ratio?

I believe its under chipset in bios, however, I think you may be limited as to setting due to the cpu, also I read I believe on the Mushkin site that pc2100 will give a different ram output on these boards...
