this is the very last driver not listed for your board but they all use the ich10r
My i have some stability isue on my 975x chipset and driver 11.2.0.1006 so i use 11.0.0.1032
But if u run stable u should stick to your driver
The speed u got is good for sata2
As maximum sata3 ssd on sata2 port i see in raid 0 is 260MB/s for 2 ssd and u run at 243MB/s
If u want more speed with out buying a new system because $$$
you could go with a PCIE 8X controller like i did
Dont tink to buy a PCIE 1x controller as PCIE is 500MB/s per-lane
SO 1x=500MB/s and 8X 5x500=4000MB/s
My i buy a Highpoint 2720 roketraid controller
A SAS to SATA with 8 sata3 port
u could see banchmarck on my post
