Enable AHCI on E1705?
After two unsuccessful chats with Dell support, I thought I might post this here and see if I could get any help.
I'm trying to enable AHCI on my E1705. For those not familiar with AHCI (as neither of the two people I contacted at Dell were) information on it can be found here:
The key technology I'm wanting to enable is NCQ, which can substantially improve the performance of the hard drive in multitasking applications. The SATA chipset on the E1705 (according to Intel's own ChipUtil.exe) is the Intel 82801GBM I/O controller hub (ICH7M). According to the page above, this chipset fully supports AHCI. The Hitachi hard drive I'm using also supports AHCI. Unfortunately, I can find no way to enable this functionality in the E1705's BIOS. What do I need to do to enable AHCI on my E1705?
Thanks in advance!
- I thought about that, but when I tried to install the Intel Matrix Storage Manager, it says that there is no supported hardware found. Intel says that error is caused by AHCI not being turned on in the BIOS. Also, there's a Dell support page for the Dimension desktop line which has instructions for turning AHCI on in the BIOS. My E1705 just doesn't have that section in the BIOS.

did you try using intel app accelerator? that shows you also.you are aware that ich7-m supports ahci, but not matrixraid - when intel says supports, often means something different
1st confirm latest chipset driver (dell download page) is installed on your e1705 - if yes - only intial bios a00 is presently available as download (but your e1705 may have shipped w/ updated bios file - confirm bios file as installed on your e1705) - you may need bios update, pending/not yet released
2nd yes hgst lists 7k100 as fully compliant re: ahci / ncq / hotplug - your e1705 hitachi 7k or 5k? (7200rpm or 5400rpm hdd?)
there are issues w/ 6 & 7 series non-matrix raid intel chipsets & "full" ahci/ncq support in notes - I noticed there is aditional download for removable storage devices/bay based - perhaps?
you intel "link" download pdf intel app accelerator users handbook page 24 of 98
ncq only available w/matrixraid - although ich7-m supports ahci - according to intel
as I wrote earlier, this is one of several issues w/ recent intel chipsets
so cpt jack, good luck yes
- Given the fact Inspiron 6400/E1505 is the "smaller brother" of 9400/1505, I post here the message.
I am also interested in activating the AHCI mode (whether it is in the BIOS or via INF file installation). As Cpt_Jack mentioned long time ago, in his first post, both the chipset (ICH7M) and the hard disk (Hitachi Travelstar 5K100 series) know about the AHCI mode but this one is not activated. In Device Manager, the storage controller is reported (or rather registered?) as Intel 82801 GBM/GHM (ICH7M Family) Serial ATA Storage Controller (no AHCI in the string as Intel Matrix Storage requires). Some new ideas?

With my SCSI drives you could turn off tagged queuing under the properties of the drive in device manager> scsi properties.
