    can't get new SSD to run in SATAII mode


    Hi all

    Not sure if this is a driver problem or not but I've just done a fresh install of Windows 7 64bit onto my new Samsung 840 EVO SSD and the drive is stuck in SATAI mode. My motherboard (Gigabyte N650SLI-DS4 - Nvidia 650i SLI chipset) supports SATAII, In fact my other, conventional, HDD is running in SATAII and has better speeds than the SSD (according to the Speed Test for the SATA port in Device Manager)!

    My motherboard doesn't support AHCI unfortunately and I can live with that but would really like SATAII to work. Any suggestions.

    What I have done so far;
    turned RAID on in my BIOS as this has helped some people achieve SATAII on Nvidia chipsets (see http://forum.crucial.com/t5/Solid-S....p/12203/page/2 for reference)
    I even edited the registry to enable the AHCI driver (in desperation as it was mentioned a lot on the web).
    My RAID was not turned on when I installed Windows and I didn't load any special drivers during the install because I didn't have any. I suppose I could reload Windows now I have turned on RAID but would want to have some hope it would make a difference

    Any help gratefully received!

    Hello CBaily. Welcome to the forum.

    SATA v1 is 1.5Gb/sec
    SATA vII is 3 Gb/sec
    SATA vIII is 6Gb/sec

    Your board has 4 SATA ports and they are all SATA II - 3 Gb/sec.

    So I'm not sure what you mean when you say that they are running in SATA I mode. What are you looking at to determine that?

    Thanks for your reply. In Device Manager I view the Properties of the SATA Controller and it shows me. See screenshot attached.

    Have you installed and run Samsung Magician yet?

    Sometimes new SATA 3 devices have trouble communicating with older controllers (although that is not supposed to happen). I'm wondering if Magician will say something different or flag a problem.

    Just a thought, but looking at the manual for the motherboard (which really doesn't tell you much) it looks as though the SATA controllers are all native yet in your Device Manager it appears as if they're in sets of two with two different controllers. Is that the case? If so, which set is your HDD connected to?

    TVeblen -I have installed and run SM. It doesn't suggest outright that there's a problem, although it does say that "AHCI Mode" is deactivated (which it is as the mobo doesn't support it) and also for "SATA Interface" it says "N/A - Unable to detect SATA interface details". When I run the performance test I get the results attached below. I have already done all the things to increase performance in the "OS Optimization" section.

    Boozad - you're right, it appears as if there are two controllers in Device Manager. The SSD is connected port 0 on the first one. On the other port on that controller is a DVD drive - it shows up as SATA2. As a test I disconnected the power from the DVD drive and still the SSD showed as SATA1. Are SATA cables versions specific or should a SATA cable work in both SATA1 or SATA2 if the hardware is capable?

    A SATA cable is a SATA cable, in other words it's the interface that differs not the cable.

    I'm looking into the problem you have but don't have any recommendations at the moment.

    Thank you Wordsworth. I assumed the cable was interchangeable but thought I'd better check - that would be an easy fix!

    try upgrading you mobos chipset drivers from you vendors website, it maybe a known bug. And or google all the Bios updates for your mobo and see if the hotfix list mentions something about such a bug/issue.

    Thanks for your reply badger906. It's quite an old mobo - I'm using the latest BIOS (there hasn't been an update for years). And I downloaded the latest Nvidia chipset drivers to install when I reinstalled Windows last night, so they're up to date.
