BIOS in AHCI mode but AS SSD Benchmark shows drive in IDE mode

[idata]

Hi,

I've an X25-M 160GB SSD in my Windows 7 notebook.

The BIOS is configured as AHCI mode but AS SSD Benchmark tells me that the drive is in IDE mode.

I've just installed the Intel INF-Update, no other drivers...

Is this normal?

Any ideas?

Thanks in advance,

Christian

Dear all,

thank you for your answers.

Correct, CrystalDiskInfo 3 tells me that the drive is running at SATA/300.

I'd installed the Matrix Storage Manager before but I unstalled it.

Currently only the chipset inf-update is installed.

The drivers details from the AHCI controller:

Is this the correct driver with the TRIM support when firmware is available?

Best regards,

Christian

msahci.sys is the correct driver for native trim support in Win 7.

Yes, the msahci.sys is the correct driver to pass TRIM automatically without the need for using Optimizer. You could install an Intel driver and run the Optimizer on schedule or manually. It is expected in the near future Intel will release its own driver to pass TRIM automatically, until then, only the Microsoft AHCI driver will pass TRIM automatically.
