How to enable NCQ?

6 posts in this topic

I'm about to build a rig using these parts:

ASUS P5GD1 Pro with 915P chipset

P4 540J 3.2 GHz

2x512Mb PC3200 Geil value RAM

Maxtor Diamondmax 10 200GB SATA harddrive, 8Mb buffer

Pioneer DVR 109

Leadtek PX6800, 256Mb

Antec SLK-2650 BQE

Now, how do I go about enabling NCQ? I've read here that something called AHCI must be enabled prior to OS installation for NCQ to work, and if it isn't, you must reinstall the OS and during that, install AHCI from a floppy? Did I get that right?

Does that mean a floppy with AHCI drivers(?) is the only way to get NCQ, even when installing the OS for the first time, or do I have a 'one shot' chance of enabling AHCI in the BIOS before that first time OS install?

Also, do I need the Intel Application Accelerator (which now only is for RAID?), considering this is a single disk setup?

Any help is greatly appreciated!

I'm guessing that the 51 views and no answers mean that no one knows?!?

I continued my research and found that the 'Intel Matrix Storage Technology' is required for NCQ, even for single disk setups.

I've also put together the parts and started on the OS install, after configuring SATA to AHCI in the BIOS (which accurately detects my Maxtor drive).

But when I come to the part where it says 'Press enter to install Windows now', I'm told that no harddrive is found.

I'm guessing that this means that you cannot install to a AHCI configured SATA disk, without installing the Intel Application Accelerator from a floppy during/prior to the Windows installation.

Can anybody confirm this?

I just find it strange and cumbersome that a brand new technology like NCQ should be utterly dependent on a legacy device such as a floppy drive (which I haven't installed in this rig...)

You can install Windows with AHCI off (SATA will appear as IDE), install Intel's SATA2 driver with the silly name, then switch AHCI on. Should work, read the docs first.

From what I've read, you cannot enable NCQ if you haven't set your SATA drive to AHCI before the OS install.

Does anyone here have any hands-on experience that either debunks or confirms this?
