Bezel Blanks
On some models, there are bezel blanks covering the 3.5-inch and 5.25-inch external drive bays that
need to be removed before installing a drive. To remove a bezel blank:
1.
Remove the front bezel (
Front Bezel on page 44).
2.
To remove the lower 5.25-inch bezel blank, gently twist and pull on the bezel blank until it breaks
free from the front bezel (1), then discard the bezel blank. If the blank needs to be replaced at a
later date, you can order a replacement blank from HP.
3.
To remove the 3.5-inch bezel blank, press the two retaining tabs towards the outer left edge of the
bezel (2) and pull the bezel blank inwards to free it from the front bezel (3).

Memory
The computer comes with double data rate 3 synchronous dynamic random access memory (DDR3-
SDRAM) dual inline memory modules (DIMMs).
DDR3-SDRAM DIMMs
The memory sockets on the system board can be populated with up to four industry-standard DIMMs.
These memory sockets are populated with at least one preinstalled DIMM. To achieve the maximum
memory support, you can populate the system board with up to either 8 GB or 16 GB of memory
configured in a high-performing dual channel mode, depending on model.
