Anyone Overclock VA503+/500 MHz Successfully?

try using the 112 MHz fsb and a lower multiplier like 112 x 4.5, that
would help some. also another way to squeeze performance is to use a IDE
controller card like the Promise Ultra 66 or 100, they really do help.

If you use a 112MHz FSB you better use a Promise IDE controller card (one of
the ones rated at PCI bus speeds of 66Mhz or less) or you're guaranteed to
get hard drive corruption by running the PCI bus out-of-spec.

I agree, but not all hard drives will show data corruption.

Most hard drives will be corrupted. Who wants to take the chance of finding
out? Not me.

chicken, what are computers for anyway ? you have to learn to take
chances. the user could do a clean install, if that works and esp if a
defrag works then you are good to go. it would only be slightly out of
spec anyway. many people have done it, go for it.

LOL. I guess it depends on what you use a computer for. A little
corruption or instability might not be a big deal for a gamer or someone
who just surfs the web, for instance, but it would certainly be a big
deal for a server at a bank or accounting firm. Everybody has his or
her own comfort level.

yeah I agree, I would not recommend to a customer, but I abuse my
computers pretty good and they tolerate it pretty well. I have only had
one that showed data corruption after raising the fsb to 140 or so, that
was a Soyo Dragon Plus with a 133 fsb, there were no dividers to keep
the PCI and AGP within spec, and I learned the hard way. Registry became
corrupt, and I had to reformat. I do run others at 138 MHz fsb, no
problems. I guess a 112 fsb on a 503+ would make the PCI run at 37 MHz
and the AGP higher too, thus the suggestion to only try with a clean
install, that way you wouldn't loose anything. But I know it can be done.
