I got my mates PC with AMD 939 3700 on a8v asus deluxe mobo with geil 3200 ram. when trying to clock it past 2.5 he gets hard drive corruption like delayed cached data was unable to be written, boots to windows and play 3d mar fine no craches watsover, prime 95 passes for 10 mins. any suggestions as to why it happens and how to overcome the issue?
thank you

IS the HDD SATA, SATA ports can lose stability when the mobo is being pushed too hard.

You probably forgot to lock the PCI-E frequency to 100Mhz. When it gets to high it corrupts hard drives because it's links to the SATA channels. Did it myself a while back when overclocking it mash up my raid array

I don't have PCI-E on this motherboard. Its AGP only. I have SATA, ATA and EXT USB Hard drives installed and all of them can develope this problem.

Is it the rev 1 or 2 mb? I had the rev 1 board and it doesn't have a pci lock so no (or very little) overclocking. It was fixed/added in rev 2

and 10 mins of prime 95 is no way any kind of stability indication at ALL.

2 hours min, 8 hours average, 24 hours if you can be bothered.

The only time I remember getting HDD corruption from overclocking was when tweaking the memory timings, most notably, tRAS.

Check your tRAS setting and make sure it is not set too low.

I use this formula to set my tRAS:

tRAS = tCL + tRCD + tRP

so, if you have 2-2-2 timings, tRAS ought to be at least 6.
