DDR333 running at 266?

My aopen board has a P4 2.0g, 400fsb cpu, does the ddr ram run at 333 or 266
because of the cpu at 400fsb?

Thanks

It depends on what board you have, what speed your memory is and what the
BIOS settings are for the memory speed.

Chris

 

The board is a AX45n-533 made by Aopen, the ram is Samsung, DDR333, speed
for ram is set to AUTO.

CPU is a P4 2.0g 512k cache, 400mhz FSB

I have done the latest BIOS, what I see in the CMOS is a setting 3:4 3:5,
DRam setting, does that make sense?

I may be very wrong but dosen`t ddr run at 266max for 400fsb? and runs at
333 for 533fsb? Technically its under utilised so the best chance to get max
performance out of your memory is to set at 2 5 2 2 and hope for the best...

Looks like you guys are right. I'm not real familiar with this board or
chipset because most of the systems I build are Athlons, but here is a link
to verify what you are saying. Looks like it is a chipset limitation.

When I see settings of 1:1, 3:4 and 3:5, which is the better ratio to
choose?

Here is the link for the SiS chipsets. According to that however, your DDR
should run at 333.

Fyi You may be looking at overclocking ratio between agp/pci dividers and
the fsb ... i may be wrong again!
