    I recently bought an Intel 320 SSD (128GB) to place on my mobile system (ASUS G73JH / HM55 Chipset). Once the clean copy of Windows 7 was done, I downloaded and installed the Intel SSD Toolbox.

    When I checked the System Tuner panel, the DIPM setting was disabled. After I enabled it, it's status changed to "Feature is optimized". Note that at this time I was using the Microsoft's AHCI default drivers, since thethe Intel RST drivers were not installed yet.

    Later, I decided to install the latest Intel RST drivers to check if it would boost the SSD performance in any way. As soon as I did it, the DIPM status changed to "Current storage driver does not support DIPM settings. Consider changing to another storage driver compatible with your system". I've also checked the storage driver details using Device Manager and it's using the "iaStor.sys" file.

    On the bottom line: IRST = DIPM disabled; Default Microsoft AHCI drivers = DIPM enabled.

    Any thoughts? Does anyone else have/had this issue too? I've been googling all day and found nothing. If I can't find an answer here, I doubt I'll get one anywhere else.

    Thanks in advance.
