133MHz FSB on an ABIT BM6

Has anyone run a 133MHz FSB on an ABIT BM6 mobo or any of its cousins? I'm considering throwing in a P3-800/133 and one of those PowerLeap adapters, and some PC133 RAM (which is so cheap right now). Soft Menu lists a 133MHz FSB, but it the 440BX chipset doesn't officially support it. I've got a C2-533@800 in there, but if I can put in a fast P3 with a 133MHz bus, it may be a nice, motherboard-replacement-free upgrade path. All Cu P3 CPUs take 1.7V, right?

hmm...does a bx440 take 133 mhz bus, i would like to say yes, i've been running my asus cubx at about 140 for about a year and a half now, very stable in photoshop, divx encoding, 3d rendering, anything i throw at it basically, i even got it clocked to 150 or there abouts, but it kept crashing during intensive computing (like photoshop filters and stuff), but it ran stable for awhile in word and internet and basic stuff like that

d00d, i hope that either your agp card is good, or you are not using one.

i forget, does the bm6 have a 1/4 pci divider option?

the idea is not bad. make sure you use a good HS\FAN combo that can fit on the bm6 ;-)

since the powerleap adapter comes with a custom clip due to the extra height of the adapter, the processor may not be that stable, so if you don't already have a shim for the fcpga, get one.

but i'll tell you this, you're better off getting a new motherboard anyway. go duron or athlon. the bx chipset is great, but the abit boards based on the bx chipset suck.

The BM6 automatically uses a 1/4 PCI multiplier at 133. But I don't think it has a 1/2 AGP multiplier, just 2/3 and 1/1 so this upgrade idea doesn't look so good anymore.

I know ABIT has a history of producing some buggy boards, but my BM6 has been a bastion of stability so far, even with my 50% overclocked CPU...that could be because I'm running memory at 100, PCI at 33 and AGP at 66, all spec.

This may be some bad news for you I had an abit BM6 mobo which I had modified to use fcpga P3s but I couldnt get it to work properly at 133 or 124 with either the /3 or /4 dividers. It had a cA2 stepping p3 550 which could run at 733 in my brothers cubx but I couldnt get more that a 110 fsb or maybe even 115 fsb working. It may have been heat a bit because I was using a shim that didnt allow perfect contact (I discovered after a while) but the onboard thermal diode temp was always pretty resonable.
