hi guys i just bought a 500$ ssd hdd (ocz deneva 2)

the hard drive is a sata 3 that can read @ 550m/b write at 525/mb

i plug in my sata2 cable to the sata 3 port which is a white (gray port) (result = cant't recognize)

i put in windows 7 and it does not find the ssd drive
however i put my ssd in a sata2 port it recognize but the speed i got was only 244m/b (read) write 199mb(write) using as ssd benchmark

and yes i did went to the bios i enable ACHI and turn off the ide but yea it still cant detect the hard drive when its in the sata 3 port...

i also download the lastest driver from marvell put it in a usb and boot from windows 7 cd and install the driver in the windows 7 screen however after install the driver from marvell it still does not pick up the ssd

It's possible that the motherboard will only do SATA3 on that port (i.e. no compatibility with SATA2). If that is the case, then yes, you need a SATA3 cable.

Yes you need the SATA3 cable.

Is the drive also not detected in the BIOS or is this purely a Windows issue?
