    But preinstall drivers should be installed during windows installation isn't it, or there is no difference?
    No, not really Windows 10 may have some drivers for your system, but do not think these. Show me a screen capture of Device Manager with IDE ATA /ATAPI Controllers expanded (left click once to open) i want to see what is installed, as you can also check what shows under the Driver Tab and date and version ( right click each controller listed and select Properties).

    Pages from motherboard manual explains the SATA connectors

    Isn't Marvel meant to be not a great controller, Intel are better
    Possibly, but that is the controller with SATA III. Intel is SATA II, he can use Intel of course and would be limited to SATA II speeds.

    If hook it to the SATA 7,6 Port and install this driver Marvell RAID Driver (SATA3) for AHCI Mode, then i believe will see it in IDE ATA\ATAPI Controller. Might be something in BIOS also that enables this for Marvell controller separately, double check there to and for AHCI. I have an use an intel controller and see nothing in storage controllers except Microsoft one as i see in yours in the Device Manager.

    Leave Marvell Console driver, i am not sure about it, try installing other marvel i showed you for IDE ATA. First hook the drives to the appropriate SATA Ports

    You may be better off with Intel SATA 2 as mentioned before being better for boot drive then Marvell. Can try the Marvell to see how it works, then go back to the Intel. Said something about buying new PC eventually.

    Marvell Raid Preinstall does not have .exe file, so I cannot run it in windows. I guess Marvell RAID Driver (SATA3) for AHCI Mode is the same one but for after windows installation - will try that one.

    I can see my Crusial SSD (just storage) when connected to Marvell 6 or 7 port and it run at 6bg/s, but when I connect my Windows drive I cannot boot up PC

    Update:

    I've just deleted Marvell Console Driver and now I have the same Standart SATA AHCI Controller and under storage no more Marvell. Non bootable drive still works at 6gb/s.
    Why I cant get my windows up on this damn Marvell, I am confused
    I used to run windows through Marvell on Windows 10 before i updated my BIOS to the latest version on clean windows install, there some additional options appeared Under Marvell controller in BIOS I don't have listed in my manual anymore - must have been changed with an update.

    I might just stick with Intel's, it takes like 15 more seconds to boot up with Marvell enabled in BIOS

    I had this issue on my laptop as well. I have a Samsung 850 EVO that is SATA III-capable but runs at SATA II (i.e. HDD speeds). I fixed it with a modded BIOS.

    @ Buzzik: Is your SSD directly connected to a SATA/MSATA port on your mobo, or is it in an optical disc drive caddy? I ask because optical drives only run at SATA II speeds at most (I think), so if your SSD is in an optical caddy then your speeds will be limited.

    Well mine does not run at all. Marvell just can't recognize bootable drive in its port, so I can't start up PC, the rest of drives are fine, just the one with Windows... and yes, it's connected directly to Marvell SATA III inside the case.
    But HWiNFO and Speccy do show that the max transfer mode is SATA II(should be SATA III) and currently used is SATA II.
    Maybe there is something wrong with my SSD, I remember I could not format it during Windows installation, because it was disconnected or something, as I found out later it was Intel's SSD self defense - you need to disconnect the power cable from SSD for a certain amount of time, then connect it back, and only then it would allow you to format it.
