I don't normally overclock, but I read that this is an easy way to boost performance of a Socket 370 Celeron. What kinds of problems or incomatibilities should I be on the lookout for when making this kind of change? The motherboard has an AGP 1X/2X slot, PCI 2.1 support, and one ISA slot.

I'm most concered about how this might affect the use of sound cards in the ISA slot. Is this anything I should be concerned about?

depending on the chipset and motherboard you can expected corrupted data on hdd , isa sound will work fine until disk corruption gets you 😀

I've run many Socket 7 boards at 83 MHz (both Intel and Via), and never had an issue. The only AGP system where I've ever run the AGP bus way out of spec was an Epox 8K3A+ (KT333). I ran that board at 209 MHz FSB (209/5= 41.8 MHz, 83.6 AGP) for years. Anything higher than that and my hard drive speed began to drop significantly.

It's am Intel 440LX. Why would there be disk corruption from an overclocked CPU? Would ECC memory mitigate this risk?

Intel PIIX4/PIIX4E IDE controller doesnt have own clock source, is hard linked to PCI clock, overclocking PCI overclocks IDE

the PIIX4 is pretty solid at 83MHz IME
