FSB overclocking project

currently stable on an Iwill KA266 at a 163mhz bus (x10=1630) on a very well cooled athlon Tbird. If i bump the FSB any higher, at all, i have stabiliity issues with my Geforce 3 ti 500, is there anything i can do to increase the stability of my Ti on the extreme agp bus. as in a Vmod, or any other tricks, the mobo does not have an option to change agp to 2x, and my memory is corsair pc2700 running at CAS2, fast.
 
Is there the ability to change the PCI/AGP dividers to 1/5 PCI and 2/5 AGP? Since those will be the dividers for a stock 166MHz bus, and you're only 3 under that, you could run your PCI and AGP devices almost in spec, while OCing the hell out of the processor and the memory.
 
the Iwill 333XP is the only mobo to support 1/5 or 1/6 dividers, no, its on 2/3agp and 1/4pci, way out of spec, but fully functional.

AGP bus is 108mhz
PCI bus is 41mhz
FSB is 326mhz
Multiplier is 10
CPU clock is 1630mhz

Its definitly the Ti500 that freaks out at higher fsbs because it only crashes in 3d operation.
Without using 3d i can get a full windows boot at the motherboards maximum rated fsb of 180mhz (360ddr).
If there is a way i can find that will get the Ti500 to work under these conditions, my project is complete 🙂
 
Are you sure it's a 2/3 AGP divider? If you're running a 1/4 PCI, then the AGP should be at 1/2. AGP = 66MHz in spec...133MHz stock FSB = 1/2 divider.
