Incorrect Tweak Enable Large System Cache

Posted in Windows XP by Community Submission

The registry key LargeSystemCache "1" on a RAID Windows XP Pro configuration will lead to disastrious read/write errors. The only way to fix is to open registry and changing the key quickly right after booting Windows and then do an official restart/shutdown.

The key is located here:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\LargeSystemCache

This tweak is widly spread to be enabled but there is never a warning for anyone on RAID! If on RAID do NOT enable this key!
