I have an Abit BH6 rev 1.0 and would like to swap out my 300a Cel chip for a 133mhz P3. Does anyone know if this board supports 133mhz fsb and how fast of a P3 chip can I put on it? Thanks for any help I am planning on swapping ram also to PC133

There is a 133MHz setting on the BH6 board.

1. On most boards that I tried it would not be stable.


2. BH6 has only 1/3 divider for the PCI bus.

I.E the bus runs 133/3=44MHz. Normal PCI bus runs 33MHz.

Not too many PCI devices run stable at that frequency.

I think the BH6 is based on the Intel BX chipset, so it is not supposed to officially support 133 MHz FSB. There is a setting for it, but that is considered overclocking and as JackMDS said it doesn't have a divider for the AGP slot so you are overclocking the video card too and a lot of video cards (especially older ones) can't take that. If you are looking to upgrade, I would suggest maybe a PIII with a 100 MHz FSB so that you can have it at regular core clock and still have good performance or you can overclock it if you want. That's what I did. Originally I had a PII 350 MHz in my machine and I upgraded it to a PIII 850 MHz.
