My PC:
Model Name : GA-MA785GT-UD3H(rev. 1.0)
--------------------------
M/B Rev : 1.0
BIOS Ver : F8
-------------------------------------------------------------------------------
VGA Brand : PowerColor Model : HD5770
CPU Brand : AMD Model : Phenom II x4 Speed : 2800

Hi all,

I've just installed new HDD-Sata3-6Gb/s-Buffer:64Mb(WD10EARX, 1TB). The Bios just recognize my new HDD 1.5Gb/s(Capabilities) while setting RAID.

This is a picture of Gigabyte manual, and the description-part is my problem.


I tried on jumper setting of my new Sata3-HDD(WD) to set it down with 3Gb/s but the Bios just recognized 1.5Gb/s, too.

I used the other official SATA cable. No change.

And my older HHD-Sata2-3Gb/s-Buffer:16Mb(SeaGate, 320Gb) still recognize this HDD-SeaGate 3.0Gb/s(Capabilities) while setting RAID.


I've bench my new HDD Sata 3 with HD Tune Pro.


It seems so-so performance. I thought our Bios could not recognize new-kind Sata3 or the mobo's south-chipset SB 710 could not recognize Sata3?



Could you please make a discussion for this my issue?

Thanks
Regard.

Hard drives cannot spin fast enough to achieve SATA 3 (6Gb/s) speeds.

The drive can briefly (milliseconds) get SATA 3 speeds from data that's in the cache buffer (in your case the 64MB cache).

Your drive can Read/Write at sustained speeds of only 110MB/s.
So your HD Tune results appear to be normal.

Here a link to the spec sheet of your drive: http://www.wdc.com/wdproducts/library/SpecSheet/ENG/287...

Thanks for taking a glance at my post.

The goal i need to get is, why my mobo can't recognize my new WD-HDD-Sata3 as Sata 3G(see the picture i posted) but Sata 1.5G .

I really need my mobo recognize recognize my new HDD as 3Gb/s(Capabilities) while setting RAID, not Sata1.5G .

Could you please discuss more...
Thanks.
