I have this board, and it seems as though the disk activity on it is a
little sluggish. I was hoping to find the correct IAA, and may have. It will
not install, however, saying that I have the incorrect hardware.

System:
P4P800 Deluxe (not an E)
512MB RAM
1-WD 36GB Raptor, second connector unused
2.4C @ 2.65GHz

I have tried installing versions 3.5 and 4.5 (latest file name
iaar45_enu.exe).

Do I need to have a RAID array set up to use the driver above?

If so, is there any way to speed up HDD performance via a driver or
otherwise?
