Drivers for Marvel 91xx Config ATA Device...  

Hello Anima mate I think are what you are after Marvell - Support - Driver Downloads the only thing I don't know is if the part number has to included.
More are Gigabyte Marvell Storage Utility 4.1.0.1921 Driver - TechSpot

JMicron JMB36X SATA Controller Driver 1.17.65 Driver - TechSpot

To find the part number you may need to run HE Info and get the deetails of that part number - if it will bring it up.
See my ditty

Using HW Info

You can test the volts on the PSU with HWInfo HWiNFO, HWiNFO32/64 -Download < download the right bit version andclose the right hand window select Sensors and scroll down to the power sectionwhere you will see what the volts are doing see my pic.

The original right hand window shows themachine running and is handy for that but for looking at the components in some detail close it and use themain left hand side panel

FOR OTHER COMPONENTS

Open each + down into the componentitself and then click on it - in theright hand side will appear all sorts of details including brands speeds andother essential info that device. See pic for example.
(I have included one for my GPU so you can see how it opens out in minute detail)

Slowly tracking this one down I think as this Google shows it points to something to do with a) that flaming part number and / or b) the board itself.

The Marvell site again is this Marvell - Support - Driver Downloads

Am going to dig around in the board site now but at least it looks like it has been a problem in the past.

Have foiund this but am not sure it is what we are looking for - fingers crossed
Motherboards - RAMPAGE III FORMULA - ASUS > open the SATA drivers up.

Dean mate what form of BIOS do you have on that board cos I have an idea that it is the older type as opposed to EUFI.

Now I have attached two pics of the different kinds of BIOS to show you what I mean by the older type. Boot and go into the BIOS let us know which it is please the blue screen one will be the older type the EUFI has a black screen and dials on and lot more on it .

Now again I have an idea that it is the older type and it needs to be set to ACHI and you need to set it to that. See this

Dean read the tutorial - having ACHI set is an advantage and it maybe why the system is refusing to do what you want.

Have a read of this before you make any decisions though. AHCI vs IDE - Difference and Comparison | Diffen

Myself I am ACHI all the way
