Chapter 2: Hardware setup2-2
2.2 Central Processing Unit (CPU)
The motherboard comes with two surface mount LGA1366 sockets designed for
the Intel® Xeon® Dual/Quad Core processor.
• Your boxed Intel® Xeon® LGA1366 processor package should come with
installation instructions for the CPU and heatsink. If the instructions in this
section do not match the CPU documentation, follow the latter.
• 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 LGA1366 socket.
• 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
To install a CPU:
1. Locate the CPU socket on the motherboard.
Before installing the CPU, ensure that the socket box is facing towards you and
the load lever is on your left.
2-3ASUS RS520-E6/ERS8
2. Press the load lever with your thumb
(A), then move it to the left (B) until
it is released from the retention tab.
Retention tab
A
To prevent damage to the socket
pins, do not remove the PnP cap
unless you are installing a CPU.
3. Lift the load lever in the direction of
the arrow to a 135º angle.

6. Position the CPU over the socket,
ensuring that the gold triangle is on
the bottom-left corner of the socket,
and then t the socket alignment key
into the CPU notch.
The CPU ts in only one correct
orientation. DO NOT force the
CPU into the socket to prevent
bending the connectors on the
socket and damaging the CPU!
7. Apply some Thermal Interface
Material to the exposed area of
the CPU that the heatsink will be
in contact with, ensuring that it is
spread in an even thin layer.
Some heatsinks come with preapplied thermal paste. If so, skip
this step.
DO NOT eat the thermal Interface
Material. If it gets into your eyes or
touches your skin, ensure that you
wash it off immediately and seek
professional medical help.

2.2.2 Installing the CPU heatsink and airduct
To install the CPU heatsink:
1. Place the heatsink on top of the
installed CPU, ensuring that the four
fasteners match the holes on the
motherboard.
2. Twist each of the four screws with
a Philips (cross) screwdriver just
enough to attach the heatsink to
the motherboard. When the four
screws are attached, tighten them
one by one to completely secure
the heatsink.

To install the airduct:
1. Position the airduct on top of the
heatsink.
2. Carefully lower the airduct until it
ts in place.
Tighten the four heatsink screws in a
diagonal sequence.

2.3 System memory
2.3.1 Overview
The motherboard comes with twelve (12) Double Data Rate 3 (DDR3) Dual Inline
Memory Modules (DIMM) sockets.
The gure illustrates the location of the DDR3 DIMM sockets:

Due to Intel CPU spec denition, the system will not boot if only one DIMM is
installed in DIMM slot A2, B2, or C2 for CPU1, or D2, E2 or F2 for CPU2. Follow
the table above for recommended memory conguration.
2-7ASUS RS520-E6/ERS8
2.3.2 Memorycongurations
You may install 512 MB, 1 GB, 2 GB, 4 GB and 8GB registered DIMMs or
Unbuffered DIMM with ECC / non- ECC into the DIMM sockets.
• Always install DIMMs with the same CAS latency. For optimum
compatibility, we recommend that you obtain memory modules from the
same vendor. Refer to the Qualied Vendors List on the ASUS web site.
• You may install varying memory sizes in Channel A, Channel B and
Channel C. The system maps the total size of the lower-sized channel for
the dual-channel or triple-channel conguration. Any excess memory from
the higher-sized channel is then mapped for single-channel operation.
• Due to the memory address limitation on 32-bit Windows OS, when you
install 4GB or more memory on the motherboard, the actual usable memory
for the OS can be about 3GB or less. For effective use of memory, we
recommend that you install a 64-bit Windows OS when having 4GB or more
memory installed on the motherboard.
• This motherboard does not support memory modules made up of 256 Mb
chips.
Chapter 2: Hardware setup2-8
2.3.3 Installing a DIMM
Ensure to unplug the power supply before adding or removing DIMMs or other
system components. Failure to do so may cause severe damage to both the
motherboard and the components.
1. Unlock a DIMM socket by pressing
the retaining clips outward.
2. Align a DIMM on the socket
such that the notch on the DIMM
matches the break on the socket.
Unlocked retaining clip
A DIMM is keyed with a notch so that it ts in only one direction. DO NOT force
a DIMM into a socket to avoid damaging the DIMM.

3. Firmly insert the DIMM into the
socket until the retaining clips snap
back in place and the DIMM is
properly seated.

2.3.4 Removing a DIMM
Follow these steps to remove a DIMM.
1. Simultaneously press the
retaining clips outward to unlock
the DIMM.

Support the DIMM lightly with your ngers when pressing the retaining clips.
The DIMM might get damaged when it ips out with extra force.
2. Remove the DIMM from the socket.

2.4 Hard disk drives
The system supports eight hot-swap SATAII/SAS hard disk drives. The hard disk
drive installed on the drive tray connects to the motherboard SATAII/SAS ports via
the SATAII/SAS backplane.
To install a hot-swap SATAII/SAS HDD:
1. Release a drive tray by pushing the
spring lock to the right, then pulling
the tray lever outward. The drive
tray ejects slightly after you pull out
the lever.
2. Firmly hold the tray lever and pull
the drive tray out of the bay.
spring lock
3. Take note of the drive tray holes.
Each side has three holes to t
different types of hard disk drives.
Use two screws on each side to
secure the hard disk drive.
4. Place a SATAII/SAS hard disk drive
on the tray, then secure it with four
screws.
Chapter 2: Hardware setup2-10
5. Carefully insert the drive tray and
push it all the way to the depth of
the bay until just a small fraction of
the tray edge protrudes.
When installed, the SATAII/SAS connector on the drive connects to the SATAII/
SAS interface on the backplane.
6. Push the tray lever until it clicks,
and secures the drive tray in place.
The drive tray is correctly placed
when its front edge aligns with the
bay edge.
7. Repeat steps 1 to 6 if you wish to
install a second SATAII/SAS drive.

2.5 Expansion cards
The system motherboard comes with one PCI-E expansion slot installed with the
riser cage to support three expansion cards.
2.5.1 Installing an expansion card to the riser card bracket
To install an expansion card:
1. Locate the two screws on the riser
cage, then remove the screws from
the cage.
2. Firmly hold the riser cage, then
pull it up to detach it from the
PCI Express x16 slot on the
motherboard.
3. Place the riser cage on a at and
stable surface, then unscrew the
metal cover opposite the PCI-E slot
that you want to use
4. Install the expansion card to the
riser card as shown
5. Secure the card with a screw.
