A good many BX boards will run at 133fsb, the only real disadvantage to doing so is that the AGP will be running at 89mhz rather than the 'proper' 66mhz, and some cards don't like that. Voodoo cards generally can handle it OK, though.

But you won't really gain much if you already have a 1ghz CPU... FSB doesn't make a huge difference on PIIIs. You'd be better off just keeping what you have and seeing if you have a 105 or 108fsb option.

The one thing that would make a big difference, though, is getting one of those Tualatin adapters and stick a 1.2ghz+ Celeron, or a PIII-S in there.

OK thanks for the advice! I will forget about the idea of OC'ing the board to 133fsb. ATM, I am content with the 1Ghz 100fsb Coppermine CPU, but I will look out for a reasonably priced Powerleap adapter..

I have problems running my Abit BF6 at 133 MHz. It's not with the trouble IMO. If you want to put a Tualatin in there, I suggest you limit yourself to the Celerons because they run 100MHz FSB.

What sort of problems do you have with your BF6? Aside from the troubles of finding a forgiving video card, decent quality BX boards tend to be rock stable at 133fsb. I'm generally not too enamored with Abit stuff, but even so, it shouldn't be that troublesome.

Yeah the AGP is the biggest issue. And unless you're happy with using a PCI video card, it's a pretty big one too. 😀

I don't think I've found a single AGP card that doesn't have at least some random flakyness with a 90MHz AGP bus.

I've had good success with Voodoo cards, ATi Rages, a few different Radeons, TNT2s, and Geforce2s and 3s. I had one Geforce2 and one Radeon 9000 that didn't care much for that speed, but that was about all. It's not like any of those were really pick-of-the-litter cards either, and there's no way I'm that lucky.

I do know that Matrox cards won't do such speeds, and the Geforce FX cards are hit-or-miss. I'm not sure about later cards, I never saw much reason to try many post-2002 cards in a PIII.

My Voodoo5 5500 AGP randomly locks up when exiting 3D mode when at 90MHz. Radeon 8500/9500/9700 = hellz no. GeForce FX = random freezes. Matrox cards definitely no. Savage 2000 barely works at default speed (hehe). I can't remember how the older Radeons or GF2/3/4s work at that speed as I rarely use those.

The most annoying aspect is that while some cards may seem to be ok, that may only mean you haven't had that infrequent random freeze yet. 90 MHz AGP is just not a happy place for any video card. I say just get an 815 mobo and live a less stressful life. Or, better yet, get a system that's less ancient in general for those Windows games.
