NOTE:

Default Memory voltage setting (at the server delivery) is 1.35V (power saving). Memory voltage can be
changed by System BIOS Set-up menu.

At Lockstep mode, strongly recommends to change memory voltage to 1.5V by BIOS set-up menu.

Memory voltage is automatically 1.5V under the following configuration (cannot set 1.35V)
