Iwill KA266/ KA266-R question

[nippyjun]

On my old mobo there was a divider setting to change the AGP clock based on the CPU clock. I don't see this type of setting on my Iwill KA266-R mobo. Is this set automatically?

According to the manual, the X4 AGP mode is default disabled. You can enable it in the bios under Advanced Chipset features. There is no jumper for this on the mobo that I'm aware of.

My bad - I saw your question as a KK-266, not a KA266. Probably the same but I'll check.

Actually the KA266 that I have doesn't have settings for 2 or 4x agp. My questions has to do with the bus speed of the AGP port. For example on my old BX mobo when I overclocked the CPU bus the AGP bus was also overclocked. So if I went up to 133 mhz on the CPU bus with a divider of 2/3 the AGP bus would be at 88.6.

The only thing I can find that may be directly related is the AT bus setting - default is at 2/4. There are 3 or 4 other settings in bios you can make. But there is no direct reference to setting the AGP bus - odd. Although section 2.2 specifications say it supports the AGP2x/AGP4x Graphics, no other reference is made to it other than choosing AGP over PCI in section 4.6.

The divider is automatically set so the PCI and AGP is default speed using the 133 bus on the KA266, not sure what the divider is above that bus speed though.
