Hi All,
I've recently bought a MSI 790FX-GD70 AM3 board with which to build myself a new system. I've also got 2x Corsair Extreme Series X64 64GB SSDs which I want to put in RAID 0 as my boot drive. The Mobo has 8 SATA connectors - 2 controlled by a JMicron JMB322 controller which is where I pluged in the SSDs. I built the system up and all went well until I ran HD Tach on the drive and found the max throughput was about 130MB/s. This was a bit disappointing as a single drive is supposed to get about 210 MB/s. So I did a bit of experimenting. Undid the RAID and installed the OS on a single drive, booted and ran HD Tach - this time the result was about 115 MB/s. Next I Plugged the SATA lead into one of the ports controlled by the SB750 and the result was about 200 MB/s. This lead me to believe the JMB322 is only using SATA 1.5 even though www.jmicron.com/JMB322.html clearly states it's SATAII compatable. I can find nothing in the BIOS to switch over to using SATAII. Has anyone got any ideas as I'm a bit stumped now. I'd really rather use the RAID on this controller as no drivers are needed and the machine boots about 10-15 secs faster.
TIA
Andy
