    Default Intel Removes IRST 11.5.0.1207 Driver From Downloads Due to Issues

    The Intel IRST driver, version 11.5.0.1207, their latest version of IRST released in July of 2012, has been removed from Intel's driver download pages. Users are reporting issues including BSODs and memory leaks, and incompatibility issues with other software. I used this driver and noticed the memory leak. If you are using this driver you should install an earlier version of it ASAP.

    ASRock does not offer this driver on any of their mother board download pages, the latest IRST driver they offer is 11.2.0.1006, which is fine. The bad driver was only available from Intel and some driver download sites, so unless you specifically downloaded and installed IRST 11.5.0.1207 yourself, you very likely do not have it on your PC.

    If you did install this driver, do not uninstall it if you have any RAID volumes on your PC. You don't need to uninstall it first regardless, just download an earlier version like 11.2.0.1006, and install it over the other, which works fine and does not compromise anything.

    I think that Intel withdrew their "OS Independent" version of the 11.5.0.1207 only! Since the Win7 (32-bit),(64-bit) bit version is still there...as of today 8-4-2012

    http://downloadcenter.intel.com/Deta...&DownloadType=

    I am guessing that maybe the that other versions of windows < Win7 might have issues ... as at the top of the page for the "OS Independent" version it states "previously released"

    Nope. The issues with this driver have only been reported by people using it in a RAID set-up. The AHCI and RAID driver downloads are identical, but Intel left the drivers available on the AHCI page, since it should work fine for people using it for that set-up.

    What are the issues? I am currently using raid, but have not noticed any serious issues as yet.

    I was using it in RAID mode, and noticed the amount of RAM memory being used kept increasing for no reason. I then learned a memory leak was one of the problems this driver has.

    Some programs will BSOD due to this driver. I had this happen with the HWiNFO program, which has never done that after years of using it.

    The fact that Intel removed it from the download pages of all their boards that support RAID (which is used by the SRT and Rapid Start features too) is enough to tell me that it is just not right.

    Interesting, that must be fairly new. It's WHQL, but not official, which is weird. Where do these drivers come from, including the beta IRST drivers, I've never seen them on Intel's web site.

    I assume this is another TRIM in RAID 0 driver attempt, or an Internet myth that it is. There's a German forum where several members claim that one or more IRST 11.5 drivers is providing TRIM (actually UNMAP) to RAID 0 volumes when using Windows 7, but I am skeptical about their conclusions.

    EDIT: Just read (in a forum post...) that 11.5.2.1001 is the '1207 driver with the memory leak fixed, and TRIM in Windows 8, blah, blah, blah... I wouldn't trust this, until we hear from Intel about TRIM in RAID 0, it's all very questionable.
