OK, some background:
I'm running on an MSI K8N Neo2 Platinum with a RAID10 array (4 SATA drives) and the notorious problem of having the first 2 SATA channels not locked with the AGP & PCI. So if I overclock the bus past about 210MHz it will quickly get disk errors & crash.
I noticed in the Device Manager that it lets me set a Transfer mode for each channel even for the SATA controllers (Either "Serial ATA DMA" or "PIO Mode"). I assume setting it to "PIO Mode" will slow down my RAID performance. I'm wondering if it will also let me overcome the overclocking limitation, kind of like how EIDE drives used to be a lot less sensitive to overclocking than ATA/33 and ATA/66. Also, if I disable DMA on the serial ATA channels in the BIOS (which is the default), will this get rid of the device manager option?
