hardware question

My problems regarding a SB16 isa on a 486 seems to be coming from the use of a pentium overdrive 80mhz instead of a DX33. It is _only_ when trying to do sound that everything breaks, otherwise its really stable. Similar results were achieved in windows. My hunch is that the cpu is in some way making dma or interrupts unstable, or maybe the entire ISA bus. I tried to read a mp3 from floppy aswell, but that also crashed. Its only in linux/windows that the overdrive causes problems, the creative dos diagnose.exe can play fine even with the overdrive. Any ideas to this weirdness?

Im not on the list so answer in private.
