Marvell SATA-III 6Gb driver failure under Win7 64bit  

I have a GA-X58A-UD5 motherboard. Installed everything from the disc that came with it but after seeing this thread I checked and the sata 3 controller was not installed. I installed the new one from Asus. I have a crucial ssd sata 3 and now in device manager its shown as: SCSI Disc Device. Is this normal for a sata 3 disc?

Before I think it was ata instead. I used to have the eject option in the notification area, just like anything you insert that is usb.

Also how can I test its speed?

I contacted gigabyte but they were not helpful. Hope someone can help me and thank you for your patience.

Get the 1051 drivers from here if you want the latest WHQL (in use on my Ausus board):

Thank you very much both. Spent a lot of money on the ssd and did not want it to be wasted.
Updated controller driver from 1042 to 1051 just now. :)

Your drive is performing great! Is it a 128GB C300?

Yes.

I've read the entire thread and my problem lies very close to this. Therefore, I decided to continue on this thread.

I am having trouble installing Win 7 Ultimate x64 on my new Intel 510 SSD drive connected to the Marvell controller (on my Asus board) in AHCI mode.
Mind you, Windows installed fine on the 510 when Marvell was in IDE mode.
I am usually able to get to the HDD selection-screen, and here I see the Intel 510 drive just fine. Then, I load the Marvell 912x Controller Driver V1.0.0.1036 (downloaded from asus.com - where I made sure to select Win 7 64-bit). I also tried the 1.0.0.1051 version - downloaded from some other place.

During the subsequent installation, the setup crashes/hangs at various times. And nothing more happens.
One time I managed to get into Windows after the installation but after one more reboot, that was the last I saw of the Desktop.

I read a guide on how to switch to AHCI controller-mode after having done the installation in IDE mode.
The guide (How to enable AHCI in Windows 7 RC after installation | iThinkDifferent), along with several other guides, talks about modifying the "msahci" entry to value "0" under
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\

This results in the same hang-situation during boot-up - after the switch to AHCI has been done in the BIOS.

Side-notes: Have run Memtest on the RAM for over 12 hours with no errors (also, the system has run stable as heck the past six months on a regular HDD on the exact same Marvell port).

I sooo need your suggestions! I find it so frustrating that I cannot enjoy my new and blazing fast hardware with the optimal settings.

First change to AHCI mode from Bios, then install Windows 7. After installation install the marvell driver version 1.0.0.1051.
I am using Windows 7 64bit too but on Gigabyte motherboard.

Thank you for the tip Soundlover. The problem is that I practically never make it through the entire installation of Windows before the setup hangs - this only being a problem when installing in AHCI mode.

In the attempt to adhere to proper forum conduct, I'd probably better refer all invested readers to this new thread on the subject here:
