Anyone have some experience with fsb maximums theyve reached? I'm curious how far I can push the pci bus before the cards(soundcard, nic, etc.) start to get flakey.
 
I've pushed the FSB up to around 250 Mhz (I think it had more in it, but it was just a test, it was Prime95 stable, but I'm waiting for my other stick of RAM before I OC).

However, I use an AGP/PCI divider so it's set at 66/33 Mhz. Running them out of spec is something I don't like to do.

You mean you don't have AGP dividers?
 
Running PCI out of spec will just make the card responding while at that speed or even kill it. But killing only happen to me with a Matrox video card. Dont remember how much fsb it had.

But really , I think the max depend's on each components, and of the same components and same brand it still differ from parts to parts.
 
the bios only allows for certain increments of adjustment for the fsb/pci (as a combined adj.):rolleyes: . you can start at an underclock of 90fsb/30 pci..........up to 150fsb/38pci. I'm toying with a thunderbird 950 (at 1.02ghz right now), so my theoretical max will be 1.43ghz. This board also doesnt let me change the multiplier:mad:
 
You mean it doesn't have multiplier options, or that the multiplier won't budge? If it's the 2nd case, the proc is probably locked.
 
No. Theres no option in the bios to change it. If there was, I'd have the proc out right now bridging the L1.;)
 
When i was running my p3-933 on my cusl3, i would normally push my pci speeds to 42 mhz.
It never caused any corruption on the install.

I did have a high end intel server nic though, so that may have helped.

But remember, your mileage may vary.
