Crosshair IV AHCI

Sycotek · 10th May 2012, 3:07 PM

Anyone else using this board in AHCI?

I recently got an SSD and plugged it in - went to storage and set it to AHCI.

Checked boot devices and it comes up as IDE:SSD

thought it was an engrish translation issue so installed win7

test ok 450MB/s (120GB) on sata3 however AS SSD reports AMD SATA driver not AMD AHCI?

have i missed anything?

Your post leaves out too much info for it to make sense. Can you try to re-word it?

When you set to AHCI, before you set the boot device you need to save and restart.

Then re-enter bios and set the boot device.

What has probably happened is that when you selected ide-ssd as your boot device, it probably switched AHCI back to ide. I had a similar problem with mine some time ago.

I think it has to do with the mbr on the ssd. Once you change the mode to ahci you will have to remove partitions and the mbr, then reinitialise and repartition.

Then you should not get the ide badge, not that it will likely affect performance much.

That is not necessary, it is probably a quirk of the AMD AHCI drivers saying it is in IDE or SATA mode instead of AHCI mode, despite the BIOS being set to AHCI for the port that the SSD is on. It did that for me.

Anyhow, I went back to the MS AHCI drivers on my WIN7-64 install because it was a tad faster.

I have a crosshair iv formula as well and that (ide) badge after the drive is present in the bios as well for any drive that was partitioned while board was in 'IDE' mode.
