high pci bus without burning out?

[fetuchin]

as i have realized my abit kt7a-raid offers a weird frequencies combination: 133/44 instead of standard 133/33, what's the use of such combination if some? isn't it highly dangerous to force pci up there or is it sure?

Actually, No! My Overclocked Pentium II system has a bus of 83MHz, but only with one PCI divider setting, you guessed it, 1/2. So I have a 42MHz PCI bus. There are people saying that cranking up the PCI bus is harmful to your components, but I haven't seen anything except Sandra telling me to put it down. I think I've actually seen a performance Increase from my crap PCI video card. But I wouldn't dare put an AGP card in it without putting down the FSB again. Anyway, some cards have problems running at an abnormal PCI bus, some don't, and some actually benefit from it. I can't determine whatever you have will fry or not, thats just a chance you'll have to take.

Sure it's potentially dangerous, and a lot of Hard Disk Drives and PCI cards won't cope very well with a 44MHz PCI bus.... but some cards will, some HDD's will. And that option is the for those that have components that can handle said bus frequency. It'd offer more bandwidth then the traditional 33MHz PCI bus, and hence could equate to higher performance... if your cards can handle the high PCI bus then it's certainly nice to have the option.

That said you will find few people willing to chance a PCI bus speed in the 40MHz+ range, and I went through a number of drives myself to get one I knew could handle a high PCI bus on my system.

I've only heard of HDD's being actually damaged by high PCI's, but I'm sure there are cases of everything.
