Oh btw Raja, my ASUS Sabertooth would crash after 15 to 20 minutes of Intel Burn Test when I had 5 or 6 SATA hard drives on the intel ports, but not when I had 4 or less, have had to move things around so am using the marvell controller and no more than 4 intel sata ports, have not tried putting more than 4 on there since I updated to the 1606 BIOS, think it is worth trying or is there a limitation on the chipset?
