    DH67BL freezes - memory issue? - setting command rate (2T) via bios impossible.

    elbman

      I have a strange problem with my HTPC

       

      DH67BL (Bios 0122)

      Windows 7 32Bit - latest Drivers

      2x Kingston DDR3 KIT 1333 2x2GB

      Tevii S464 Satelite Card

      Crucial M300C 64GB

       

      Sometimes the OS freezes. It seems to be a memory issue. Detecting Memory Timings in Bios is on automatic.

       

      Timings are same as in SPD but Command Rate is always 1T, do not really know if this is supportet by Kingston.

       

      I would like to chose a command rate of 2T manually (for better stability), but setting this value in Bios does not take any affect.

       

       

      Anyone could help me or having the same problem?

       

      thank You!

          Hi,

          A lot of owners of SSD drives including the one you own have windows 7 freeze more or less frequent, this is not related to this motherboard.

          A workaround (or two) have been found to solve this issue which it told to be related to low power management for the sata ports not well compatible with some SSD .

          One workaround is to set enabled sata hotswap option in the bios (have seen this for Asus motherboards)

          Another one probably more effective is to add some entries in the registry to disable LPM.

          Here is the matérial to prepare a .reg file to do the job:

          Cut and paste the following to a text file with notepad and record it as nolpm.reg then double clic on it to execute, then restart:

           

          Windows Registry Editor Version 5.00


          [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\iaStor\Parameters\Port0]

          "LPM"=dword:00000000
          "LPMDSTATE"=dword:00000000
          "DIPM"=dword:00000000


          [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\iaStor\Parameters\Port1]

          "LPM"=dword:00000000
          "LPMDSTATE"=dword:00000000
          "DIPM"=dword:00000000


          [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\iaStor\Parameters\Port2]

          "LPM"=dword:00000000
          "LPMDSTATE"=dword:00000000
          "DIPM"=dword:00000000


          [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\iaStor\Parameters\Port3]

          "LPM"=dword:00000000
          "LPMDSTATE"=dword:00000000
          "DIPM"=dword:00000000


          [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\iaStor\Parameters\Port4]

          "LPM"=dword:00000000
          "LPMDSTATE"=dword:00000000
          "DIPM"=dword:00000000


          [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\iaStor\Parameters\Port5]

          "LPM"=dword:00000000
          "LPMDSTATE"=dword:00000000
          "DIPM"=dword:00000000

            Thank you for your fast reply!!!!!!!!!!!!!!!!!!

            I flashed newest firmware on ssd and deaktivated lpm.

             

            until now no more freezes :-)))))))))))))

             

            I'll try a few days, would be perfect if this was the solution.

             

            Many thanks again
