Ah man! I had the "Marvel 91xx Config" showing in my device manager for about a year or so now and finally I was able to find the driver that the device manager "auto search online" couldn't find. Thanks Fernando! You're a life saver man because I've searched everywhere for it, even corsairs website and to no avail there wasn't any drivers for this drive listed. Now I can finally get this Corsair Force GT working with Windows 8.1 pro because of it -- completely installed now. :D

I registered specifically to say this; thanks again!

Sorry for bringing up a question that may have already been answered before:
I have a laptop with Intel ICH8M SATA AHCI chipset and I'm looking for the latest "Classical" Intel RST Drivers & Software Set for Windows 7 x64. I'm a bit puzzled because there are 2 threads with recommended Intel RST 11.2.0.1006 modded by Fernando:

1) Universal Intel RST Drivers & Software Set v11.2.0.1006 mod by Fernando in Recommended AHCI and RAID Drivers
2) Universal Intel RST Drivers & Software Set v11.2.0.1006 mod and signed by Fernando in Modded Intel AHCI and RAID Drivers

Which one should I use and what is the practical difference between them ? Can I install the first one ("mod by Fernando" variant) under any Windows OS (e.g. 7, 8.1 or 10) the same way as the second one ("mod and signed by Fernando") ? Will I get Driver Signature errors in Win 7/8.1/10 with the first variant ("mod by Fernando") ?

I would appreciate a good explanation to this issue, because I can't find a detailed description of which one is better and why.
Thank you in advance !

These modded drivers have been digitally signed by me, but unfortunately I seem to be the only one, who benefits from this procedure. The digital signature is obviously only accepted by my own computer.

These are the consequences for all users (except myself):
1. The installation of these "modded & signed" Intel RST drivers v11.2.0.1006 has to be forced by using the "Have Disk" button (valid for all Windows Operating Systems).
2. Users, who are running Win8/8.1/10, have to disable the "Driver Signature Enforcement" and to reboot, before they can install these modded drivers.

I have updated MARVELL driver (AHCI mode) from V 1.2.0.1014 to V 1.2.0.1045.
TRIMCHECK is working fine with this new version which drives my SSD Samsung PRO 840.
A great progress.

I agree with you that in fact V 1.2.0.1045 is not a progress because after updated from .1014 to .1045 but without reboot the TRIM was successful (this was the first test i had done)..
This seems the .1014 was always in fact effective even if displayed infos was .1045.

However, after a PC reboot , the .1045 was full effective and I detected that .1045 did not get TRIM ok. (many checks done).
I think have explained somewhere in a post.

So, at the moment i keep .1014 on my PC because I am sure TRIM is ok, and so the connected SSD the MARVELL port is properly TRImed by W7, and hardware reliability is better.

On the net we can find lot of links to the 32/64 bit Marvell AHCI/RAID SATA 6G drivers V1.2.0.1014 for XPVistaWin7.

I have an ASUS P8Z77-V DELUXE motherboard, and for example on ASUS site you can download this driver.

This is a link which can be used:

Link to get Marvell_V1201014

If I remember well I've used 1.2.0.1040 supporting TRIM, however same crap performance. I probably still have it at home. Will have a look tomorrow night if you like. Can I upload it as attachement?

EDIT: need to replace my memory Just tried 1.2.0.1040 and no TRIM.

@Fernando,
I have not found v1.2.0.1040 driver on the net.
Today, I have done in depth tests to find the most recent version for Marvell 88SE91xx PCIe SATA 6GB AHCI driver.
For me TRIM is supported for sure with v1.2.0.1014 (19/09/2011) , and with v1.2.0.1035 (24/01/2013).
For me TRIM is NOT supported for sure with v1.2.0.1039 (05/09/2013), and with v1.2.0.1041, and with v1.2.0.1045.

So, at my knowledge, for my motherboard (ASUS P8Z77-V Deluxe) (Bios 2104 up to date), the "best" and most recent driver TRIM working I recommend is v1.2.0.1035.
Some benchmarks are attached.
Obviously performance are very poor compared to the same SSD connected on an Intel Z77 port. This a well know fact.
Obviously Microsoft MSAHCI 1.0 2006 driver does support TRIM (I have used it several months, but with less performance than Marvell v1.2.0.1035).




May be v1.2.0.1045 offers better performance (than older versions) when you have connected 2 HDDs on the P8Z77-V Deluxe Marvell ports.
If you mix HDD and SSD on the 2 available Marvell ports I recommend to install the driver which does support TRIM as explained above.
