Yes, one thing this used to do was to cause data corruption on certain Maxtor hard drives, at least under windows. I think in linux, you can pass a idebus= option to the kernel to tell it that the bus is overclocked. > I know some BIOS will take care of this by locking AGP and > PCI to a certain value, but I wouldn't count on it with an older > board/bios. Also, even when the PCI bus is run asynchronously, while the data corruption issues aren't around anymore, there is unfortunately a latency tradeoff, which may make using a 75MHz/83MHz FSB not even worth it in the end. -- Ryan Underwood, <nemesis@xxxxxxxxxxxx> -------------- next part -------------- A non-text attachment was scrubbed...
