i have AHCI enabled in Bios
is this something that ive done wrong?
ive no other HDD's attached yet.
 
Which AHCI controller is it plugged into? Swap to the other and try again?

Intel controller = SATA2_0, SATA2_1, SATA2_2, SATA2_3, SATA2_4, SATA2_5
Marvel controller = GSATA3_6, GSATA3_7

*edit*

Just read at Gigabyte there is a bios update F13b (it is a beta) which specifically addresses SSD incompatibility. I feel this is the way to go. Good luck ;)

Hi cheers for reply. I've it plugged into Intel controller. Have tried 2 different sata ports 0 & 4. I've the latest bios installed f13b.
Should I have unplugged the data cables from the motherboard when installing Windows? I only unplugged them from the hdd
 
So long as the hdds are disconnected from the motherboard it really makes no odds. I gotta let someone else step in now, I'm unfamiliar with your board. Good luck ;)
 
I had this issue on a Gigabyte X58 board and was due to running the controllers on IDE or legacy mode.
Did you install W7 on IDE mode and then change to AHCI ? If so, there's a registry tweak that needs to be made. Unfortunately, I'm not sure what it is.
I solved mine by flashing the board to latest BIOS using Q-Flash, and then re-installing under AHCI with only the SSD plugged in, all other disks unplugged.
 
Hi I installed it first by disconnecting hdds but forgot to set ahci. Then I redid the install with drives disconnected and set to ahci but still had the issue.
 
I just changed AHCI to IDE in the Bios and that issue went away but so did about 80mb from the speed of the ssd on benchmark.
with AHCI its about 280mb and on IDE its 210mb
my board only supports Sata_2 not Sata_3
is that a decent speed for the SSD?
i reattached my HDD's and the issue is still there.
how do i check if AHCI is correctly running
 
It looks like it's the motherboard that's the problem, that doesn't seem to be 100% compatible with SSDs. Does add to the boot time but as long as it boots it's fine. Hopefully Gigabyte will release a newer BIOS version to overcome the problem (a beta is still a beta after all).
