ECS P6BAT-A+ AND MEMORY

[arisaa]

Hi guys,

My motherboard is an ECS P6BAT-A+ which is supposed to operate with the VIA apollo pro 133 chipset (Northbridge 693A, Southbridge 596B) as stated at the ECS site.
Can anybody explain why some utilities claim that the Northbridge is 691 rev.42 or 66 and only one recognizes it as 693A ?
Here comes my actual problem :
I have installed a 256 mg pc133 memory chip but the memory bus runs at 100Mhz that is at my processor's fsb. VIA states that this chipset can handle the memory bus running at a different speed than the fsb, so you can have memory bus running at 133Mhz with pc133 memory and fsb running at 100Mhz. I think the problem lies within the bios where there is a setting for memory to run at host clk or host clk minus 33. There should be an option of host clk plus 33.
Do you know how I could add this option ?
Any suggestions ?
I have already upgraded to the lattest bios version issued by ECS.

Thanks

Regarding the ID problem, those VIA chips actually have that ID programmable. In order to avoid confusing old software and existing operating systems, many BIOSes kept the ID at 691 even with the 693 and 693A chips. Nevermind.

As far as the clocking options are concerned, I wouldn't bother. That processor of yours won't be able to use the extra headroom anyway.

Thanks for the reply Peter,

I thought that if memory run at 133 MHz the differnce from 100 MHz would be quite significant. My processor is a
PIII 500 \100FSB.
