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

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
