Memory Module Guidelines
To ensure optimal performance of your computer, observe the following general guidelines when
configuring your system memory:
• Memory modules of different sizes can be mixed (for example, 2 GB and 4 GB). But, all populated
channels must have identical configurations.
• Memory modules must be installed beginning with the first socket.
NOTE: Registered DIMMS (R-DIMMs) and Load Reduced DIMMS (LR-DIMMs) cannot be mixed.
• If memory modules with different speeds are installed, they operate at the speed of the slowest
installed memory modules.
NOTE: If all DIMMs are 2133, the CPU ordered may run the memory at a slower speed.
Front Panel Chassis Lock
The front panel chassis lock allows you to lock the front panel. The lock is located inside the chassis. It
consists of two buttons:
• orange button — press this button to lock the front panel.
• green button — press this button to unlock the front panel.
NOTE: To lock or unlock the front panel chassis, always ensure that the left cover of the chassis is
removed. For information on removing the left cover, see Removing Left Cover.
