I am currently running Windows 7 64-bit on an Asus Maximus Formula mobo using the intel X38 chipset. I have installed the new Intel chipset utility software dated 12/22/09 and all it installed was a SATA channel driver. No harm no foul. I check device manager and it still shows my WD Black 1TB HDD on "Standard IDE Port" at UDMA 5. Not the Intel ICH9 Standard SATA Controller. Hmmm... In details, it shows no attached drives.
In my bios I have it configured for IDE mode, not AHCI or RAID. Is this why? If so, are there really any true advantages moving to AHCI?
I ran HDD tune and it confirms the UDMA 5 status, is this not due to the standard drivers? For supported it shows UDMA6, but for active it shows UDMA 5.
When I look in device manager, it shows my system devices such as my intel PCI-Express Peg Root and other drivers are provided by Microsoft, not intel.
I remember with Vista the intel chipset utility updated all of those from what MS threw at us.
If anyone can shed any light on this subject it would be deeply appreciated. Am I missing something?
I've switched a fairly fast hard disk (WD6401AALS) and I'll admit that I can't detect the difference on a PC. The difference can barely be detected on a server with significant I/O from several clients or VMs.
