Safety information

Electrical Safety

• Before installing or removing signal cables, ensure that the power cables for the system
unit and all attached devices are unplugged.

• To prevent electrical shock hazard, disconnect the power cable from the electrical outlet
before relocating the system.

• When adding or removing any additional devices to or from the system, ensure that the
power cables for the devices are unplugged before the signal cables are connected. If
possible, disconnect all power cables from the existing system before you add a device.

• If the power supply is broken, do not try to fix it by yourself. Contact a qualified service
technician or your dealer.

Chapter 2: Hardware Information

Hardware Information

This chapter lists the hardware setup procedures that you have
to perform when installing or removing system components.

2.1 Chassis cover

Removing the rear cover

To remove the rear cover:

1. Remove the six (6) screws on the rear cover with a Phillips screwdriver.

2. Push and hold the cover buttons down, then slide the rear cover towards the rear to
disengage it from the chassis.

3. Lift the rear cover to completely remove it from the chassis.

2-2

Chapter 2: Hardware Information

2.2 Central Processing Unit (CPU)

The motherboard comes with a surface mount Socket SP3 designed for the AMD EPYC™
7002 Series.

• Upon purchase of the motherboard, ensure that the PnP cap is on the socket and
the socket contacts are not bent. Contact your retailer immediately if the PnP cap
is missing, or if you see any damage to the PnP cap/socket contacts/motherboard
components. ASUS will shoulder the cost of repair only if the damage is shipment/
transit-related.

• Keep the cap after installing the motherboard. ASUS will process Return Merchandise
Authorization (RMA) requests only if the motherboard comes with the cap on the
Socket SP3.

• The product warranty does not cover damage to the socket contacts resulting from
incorrect CPU installation/removal, or misplacement/loss/incorrect removal of the PnP
cap.

2.2.1 Installing the CPU and heatsink

To install a CPU:

1. Remove the rear cover. For more information, see the section

2. Remove the screws then remove the air ducts.

3. Loosen each screw one by one in the
sequence shown on the socket to open
the load plate.

4. Slightly lift open the rail frame.

5. Slide the external cap out of the rail
frame.

6. Slide the carrier frame with CPU into the
rail frame, then remove the PnP cap.

The carrier frame with CPU fits in only
one correct orientation. DO NOT force
the carrier frame with CPU into the
rail frame.

7. Gently push the rail frame just enough
to let it sit on top of the CPU socket.

8. Close the load plate just enough to let
it sit on top of the CPU, then secure
each screw one by one in the sequence
shown on the socket to completely
secure the load plate.

The load plate screws are
T20 models. A torque value of

16.1±1.2 kgf-cm (14.0±1.0 lbf-in) is
recommended.

9. Twist each of the four screws with a Phillips screwdriver just enough to attach the
heatsink to the motherboard. When the four screws are attached, tighten them one by
one in a diagonal sequence to completely secure the heatsink.

10. Reinstall the air ducts then secure the air ducts with the screws removed in step 2.

2.3 System memory

2.3.1 Overview

The motherboard comes with 32 Double Data Rate 4 (DDR4) Dual Inline Memory Modules
(DIMM) sockets.

The figure illustrates the location of the DDR4 DIMM sockets:

2-7

2.3.2 Memory Configurations

You may install 16GB, 32GB, and 64GB RDIMMs into the DIMM sockets. If you are not sure
on which slots to install the DIMMS, you can use the recommended memory configuration in
this section for reference.

• Refer to ASUS Server AVL for the updated list of compatible DIMMs.

• Always install DIMMs with the same CAS latency. For optimum compatibility, it is
recommended that you obtain memory modules from the same vendor.

• Start installing the DIMMs into the second slots (such as DIMM_A2 , DIMM_B2, etc.)
