I originally set up this mobo with the WDC 1002FALS SATA2 HDD as primary. It was quick and reliable. Then I bought the 1002FAEX SATA3 (6GBs) HDD and set it up on the ports that use the Marvell chip. It was quite unreliable. I saw many BSODs, most often on waking up from sleep mode. So I jumpered the HDD to limit it to 3 GBs and connected it to one of the mobo's SATA2 ports. Now we're back to complete reliability and good speed. I have no way of telling whether the problem is in the HDD or the mobo. Anybody have any insight into how to make SATA3 work with this mobo?
