System:
Intel Q9450 - stock speed
DFI LanParty LT X48-T2R
8GB DDR2
WD Raptor 150GB
NV 8800GTS-512
Vista Ultimate 64
I'm using the built in SATA controller and everything is configured for performance. Running the latest version of HD Tune.
Basically my issue is that if I enable AHCI in the BIOS, which has been enabled since the day the OS was installed, my CPU utilization is around 30%.
If I turn off AHCI in the BIOS, setting to IDE mode, the CPU utilization falls to 1.7% which seems correct.
Anyone have any insight? Thanks!
