Summary

Impact of C1E Setting on Dell PowerEdge 11G Servers With Purple Screen of Death (PSOD)

Question

What might cause a PSOD host crash with some Dell servers running ESXi5.x?

Answer

ESXi 5.x PSOD Server crashes can be caused by two Dell BIOS Settings. To prevent the PSODs from occurring disable the following settings in the Dell Server Bios:

C1E....................................Enabled
C States............................. Enabled

change to disabled:

C1E.................................... Disabled
C States..............................Disabled



This Dell wiki article describes C States and specifically the C1E setting; it's a method for reducing power consumption by powering off cores when not in use.
