Hi Tinux,

have you reach sata III speed now, when f.27 released?

i now choose a ssd for 6560b and intel 520 looks interesting for me

BIOS F.27 does not make any changes of the sata speed being the same at sata2 only

user can get sata III speed with crucial m4 when rolled back to f.20

[corephil]

I am using Crucial m4 and Samsung 830, both 128gb. It should matter when using either sata 2 or sata 3 ssd, when the sata 600 speed is supported.

F.20, is it? Then I should try to find out. I am not sure if the BIOS can be rolled back (have not done before).

I will post the results once I rolled back to F.20.

Thanks for the info.

@ ovsale... U are the best  ^_^ ! F.20 runs my Probook 6460b at sata3 speed.You are great man. Kudos to you and to the info you have provided.

Now I understand why other systems @ F.20 runs sata3 while others only sata2 speeds. When I did roll back to F.20 from F.27, initially my sata speed remained at sata2. When I updated to the latest Intel RST driver (from Intel Support website), finally I got sata3 speed. Therefore, 2 things will be needed in this case as follows:

 1. Roll back to F.20 bios version

 2. Install the latest Intel RST driver from Intel Support page only.

Further to this, I tried loading the F.27 bios update once again hoping that maybe it is the RST driver that actually made the difference. After the F.27 update, my sata transfer rate went back to 3gb/s according to Intel RST manager. I tried the F.22 as well, and it gave me the same sata 3gb/s transfer rate.

@corephil

everybody happy but me) i`ve got intel 520 ssd and now try to get sata 3 speed. i`ve setup windows with F.27 bios. and then try to update bios to F.20. but windows can`t start from ssd with this bios. i`ve rooled back F.27 and get my win working but only sata2 speed.

i use windows 8 RTM. ssd in main slot. i`ve tryed both legacy boot and UEFI boot. where i wrong? i think it is not win8 issue.

Has anyone tried if the F.28 BIOS update resolves the SATA 2/3 issue?

[ovsale]

for me - not. and set 6gb/s in bios can cause not stable work or even not boot...
