dbw09 Posted July 13, 2011 Share Posted July 13, 2011 I posted this in another thread, but I thought it may be easier for the community to find it if I re-post this in a separate thread. Many new SSDs are experiencing freezing problems, and this is not only a Corsair and/or Sandforce issue as many other manufacturers are having this issue as well. Many people have had the freezing issues stop by using a simple registry edit that disables some power saving features for the SATA ports of your system. This has been proven across multiple platforms and systems to decrease/eliminate the freezing issues. While disabling the LPM on every SATA port will work, it is easier (and also better for battery life/electricity costs!) to disable LPM for only the port that your SSD is on, typically Port0. To do this, follow the instructions below. NOTE: Please follow these instructions at your own risk! I personally have used this procedure on 5 systems so far, and many others have used it successfully as stated on multiple forums. However, as with any registry editing, serious issues can arise if you somehow mess things up! Be careful! NOTE: This only works if you are using the Intel RST drivers. If you are using the default MS AHCI drivers, this will not work. 1) Copy the below text and paste it into a notepad file, and save the document with a .reg extension. 2) Execute the file 3) This will disable the LPM for ONLY Port0, which will allow the SSD to operate without freezes (we hope!) as well as allow your other hard drives to still use LPM. If your SSD is NOT on Port0, edit the file to have it disable LPM on whichever port your SSD is connected to. Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\iaStor\Parameters\Port0] "LPM"=dword:00000000 "LPMDSTATE"=dword:00000000 "DIPM"=dword:00000000 Link to comment Share on other sites More sharing options...
