DIMM Module Population Sequence
6
When installing memory modules, the DIMM slots should be populated in the following
order: DIMMA2, DIMMB2, DIMMC2, DIMMD2, DIMME2, DIMMF2, DIMMG2, DIMMH2, then
DIMMA1, DIMMB1, DIMMC1, DIMMD1, DIMME1, DIMMF1, DIMMG1, DIMMH1.
•
•
Always use DDR4 DIMM modules of the same type, size and speed.
•
Mixed DIMM speeds can be installed. However, all DIMMs will run at the speed of the
slowest DIMM.
•
The motherboard supports an odd number of modules (1, 3, etc.). However, to achieve the
best memory performance, a balanced memory population is recommended.

Hard Drive Installation
Removing a Hot-Swap Drive Carrier from the
Chassis
1. Press the release button on the drive carrier, which will extend the
drive carrier handle.

2. Use the drive carrier handle to pull the drive out of the chassis.
Removing a Drive Carrier
Installing a Drive
1. Remove the dummy drive, by removing the screws securing the dummy drive to
Dummy Drive
the carrier. These screws are not used to mount the actual hard drive.
2. Insert a drive into the carrier with the PCB side facing down and the connector
end toward the rear of the carrier. Align the drive in the carrier so that the screw
holes line up.
3. Secure the drive to the carrier with four M3 screws, included in the chassis
accessory box.
4. Insert the drive carrier with the disk drive into its bay, keeping the carrier oriented
so that the release button is on the right side. When the carrier reaches the rear of
Hard Drive Carrier
the bay, the release handle retracts.
5. Push the handle in until it clicks into its locked position.
