Asus P6x58D-E Marvell 9128 SATA 3 problems

I've had this system for a while and I've constantly had problems with the sata 3 ports. Sometimes it works and I can see my two hd, other times I have to reboot, go into bios (make no changes), exit and it works again.

I just purchased an OCZ 120G Vertex 3 SSDto use as a boot drive and can't get it to work on the sata 3 ports. I've read that the Marvell 9128 controller isn't the best but I would think It should at least recognize the drives.

Mobo is an Asus P6x58D-E

So this is what I've done.

1. Connected ssd to normal sata 2 ports. No hard drives connected. Booted up
and loaded windows 7 (64bit).

2. Load mb drivers from asus cd including Marvell controller.

3. Restarted and went into bios to set marvell port to AHCI mode.

4. Shut down and connected SSD to marvel sata 3 port.

5. Boot up, works fine.

6. Shut down and add hard drive to sata 2 port.

7 Boot up and system can't find ssd

8. Move ssd back to sata 2 port and all is well again.

Very frustrating. Does anyone know of a fix for this problem?

The very first time installing windows I had the ssd connected to the sata 3 port and at the disk format screen it asked for a driver. I couldn't find a file for marvell, just the exe to install the driver. This is when I moved back to the sata 2 port.

Thanks. I will have to do this when I get home but I did download the latest driver from the web and try it.

I noticed the same problem when i bought and installed my new SSD Corsair Force GT. I didnt show up in the Boot section in the bios but i found a way. I didnt show in the Boot section in bios at first but when i whent into the Disc Drive Section it was there and after i hade set it to the first device it showed up in the Boot section and i was able to select it as first boot device. Hope this helps abit, even if its abit late Regards
