Why no 166/133/133MHz memory setting on Iwill KK266?

I think this is the most important memory tweak that we can really benefit from. Right now the only thing that limit me from going to/over 166MHz fsb is my pc150=PC133. Does anyone have an idea as to why Iwill did not incorporate it in the bios. Thanks for you ideas.

The Iwill has a jumper for 100/133. This is good because it allows for a hard coded 133 FSB. In the Iwill Smart Settings you can change your FSB by typing in a value. If using the 100 jumper you can change it from 100-132. If using the 133 jumper setting you can change it from 133 up. I haven't tried setting mine at 166 but I know it will do 143 just fine. Thats a video card issue on my box and you may not have that problem. I read somewhere there is a guy running 170 something so you should be able to do this in the BIOS. Just type in your value.

Thanks seabhac. I don't think my head is thinking straight today. I got confused with the DRAM Clock feature is my other intel/via chipset mobo, which lets me select from HCLK -PCI33, HostCLK and HCLK +PCI33. I can run the fsb at 133MHz with a pc100 ram. It's probably not possible to have a stable system to run 166MHz fsb with a pc133 ram at 133MHz. If there is such setting I might be able get my pc to reach as high as 183MHz CAS2 with my PC150.

What do you intend to achieve? At 183 your pci and agp buses are out of wack. The main reason for high fsbs is that they enhance memory throughput. Running fsb higher than ram speed gains no performance but increases instability. Now if there was way to run ram at 166 and fsb at 133 that could make a nice stable system .

Yomama, "ram at 166 and fsb at 133 that could make a nice stable system" That exactly what I want to see. Remember that 200MHz fsb, maybe Iwill has some tricks under its sleeve. Since we are all for overclocking, I sure would like to see the highest fsb I could overclock this baby to. Abit got to 183MHz fsb, why not Iwill.
