Your motherboard supports SATA II.
The Advanced Host Controller Interface (AHCI) is a hardware mechanism that allows software to communicate with Serial ATA (SATA) devices that are designed to offer features not offered by Parallel ATA (PATA) controllers, such as hot-plugging and native command queuing.
We can't saturate SATA 1.5 GB/s, so don't worry about 3.0 GB/s, as long as you didn't jumper the new drive.
I would like to enable AHCI, but it's this I am having problems with...
I have an Intel DG965RY motherboard & chipset and am having major problems trying to install Vista (32 bit) with AHCI for my SATA-II drive.
I can install Vista and the drive fine using the BIOS SATA IDE Setting (though the UDMA does not seem to be what I expected) but whenever I change the BIOS setting to AHCI, I get problems upon installing.
I am using Vista 32-bit, and it's my understanding that I do not use the F6 method for installation, but merely Select the "Load Driver" button during the Vista installation.
I downloaded the files as per the Intel site and have put them onto a floppy.
However, when I click on "Load Driver", the only way I can see any items is to unselect the "only show compatible drivers for your hardware" checkbox.
So my first question is why are there no "compatible" items shown in the first place?
According to the Intel site, the DG965RY chipset supports transfer rates of up to 3Gb/s and AHCI. In addition, the AHCI option appears in the BIOS (though there is no RAID option).
So, based on this information, I would have expected to be able to take advantage of AHCI.
So this is as far as I have been able to get.
Do I need to do something else? Have I missed something? Between the mobo, the BIOS, Vista, Drivers and the AHCI Controller, I'm lost and have no idea what to do or try next.
It's the latest one, as I downloaded it from Intel's site and updated it myself. I think the number (which was part of a bigger string of numbers) is 1755. The board/chipset is the DG965RY. The documentation or the board and chipset states interface speeds of upto 3.0Gb/s are supported.
It does work without AHCI but AHCI is what I want to use.
Thanks evongugg but sadly that did not work for me (it was one of the first things I tried when first looking at this problem).
This problem relates to getting a AHCI driver to work with my mobo, which is a DG965RY. It's ICH8, and Intel says that does not work with AHCI but clearly from doing web searches, there are plenty of people who have got this to work. The F6 method has worked for people with XP, but I'm having problems with Vista Ultimate 32 bit; using the "Load Driver" method in combination with the driver file just results in my Vista clean installation failing.
can u plz help me i have same problem............
my motherboard is same dg965ry my hard disk in WD400
i have same problem when i load driver its not install ..... how will i install?
Why do you need AHCI? It provides no performance benefits if you have a single hard disk. It makes a minor difference on a server with a few hard disks
and several users accessing it. I never bothered with AHCI on my DG965RY, but I use it on my GA-EP45-UD3P running Windows Server 2008, but benchmark are required to measure the performance difference.
AHCI is required for eSATA hotswap, but that motherboard doesn't even have an eSATA port.
