nForce 720a stuck at SATA I
Hello all I recently purchased a new fast SSD. It is capable of operating on a SATA III bus. I know that the nForce 720a chipset only handles SATA II, but when I looked at the driver it said that it's only running at generation I. What can I do to get this to generation II? Attached is an image of what the driver is telling me. Also below is a link to the SSD:

Thanks for your reply.

Your problem is a wellknown one for nForce chipset mainboard users with an OCZ SSD. For details you may look into [url=http://www.ocztechnologyforum.com/forum/showthread.php?96124-Nvidia-chipset-users-seeing-1.5Gb-s-and-not-3Gb-s-from-Vertex3-Agility3-Solid3]>this<[/url] OCZ Forum thread.

Besides that I recommend to do the following:[list=1][*]At first step you should make sure, that the SSD is connected with the first SATA port (usually named "Port0") of your mainboard and the SATA Controllers have been set to "AHCI" mode within the BIOS.
[*]To get the full SATA2 speed of the on-board SATA Controller(3G/sec) you should try to replace the NVIDIA nForce SATA driver by the generic MS AHCI driver.
This is the way:[list][*]Open the "IDE ATA/ATAPI Controllers" section of the Device Manager.
[*]Right click onto the "NVIDIA nForce Serial ATA Controller" > choose "Update Driver Software" > "Browse my Computer" > "Let me pick...." > let the Device Manager show all compatible devices > choose the listed "Standard AHCI 1.0 Serial ATA Controller" > OK.[/list]After the next reboot your SSD will be maaged by the MS AHCI driver named MSAHCI.SYS. Big advantage: You will get automatic Trim support for your SSD.
[*]Additionally I recommend to enable the "Write Caching" of the OCZ Vertex3 SSD (Device Manager > "Disk Drives" > right click onto the Vertex > Tab "Policies" > "Enable Write Caching").[/list]
