TRIM does not not despite the AHCI mode and fsutil behavior query disabledeletenotify to return 0

Hello

I recently changed my motherboard to a gigabyte a ASRock x 79 Extreme9.

After this of course being the new is configured to AHCI mode and update an existing installation of Win 7 x 64 drivers using the DVD provided by ASRock, I used trimcheck - 0.7.exe to check if the trim was working, and he's not. Trim was collaborating with the Gigabyte mobo.

I made sure also that HKEY_LOCAL_MACHINESystemCurrentControlSetServicesMsahci\\\ and HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\IastorV starting value was 0, does not.

Device Manager shows that my 2 SSD using a SCSI driver, which might be the source of the problem. I tried to update the driver automatically, but Windows kept existing ones, saying that he could not find better.

No idea what is the problem and how to solve?

Thank you.

ASRock has suggested to do a new clean install W7, and it worked.

Installation on the previous mobo was a unique one partition boot, and the new is a type of 3-partition GPT.

TRIM was working on the previous mobo, but anyway when re-use of previous installation even with new pilots was not.

So, it was a problem of Windows, but that appeared to require a clean install to fix.
