P5M2-R CPU Socket 775
The system motherboard comes with a surface mount LGA775 socket designed
for Intel® Xeon 3000 series and Xeon X3200 series processor in the 775-land
package.
•
Upon purchase of the motherboard, make sure 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 LGA775 socket.
• T he product war ranty does not cover damage to the socket cont acts
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, make sure that the cam box is facing towards you
and the load lever is on your left.

2. Press the load lever with your thumb (A), then move it to the left (B) until it is
released from the retention tab.

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.
4. Lift the load plate with your thumb
and forenger to a 100º angle (A),
then push the PnP cap from the load

The motherboard supports Intel® Pentium® 4 LGA775 processors with the Intel
®
Enhanced Memory 64 Technology (EM64T), Enhanced Intel SpeedStep®
Technology (EIST), and Hyper-Threading Technology. Refer to the Appendix for
more information on these CPU features.
2.2.2 Installing the CPU heatsink and airduct
To install the CPU heatsink:
1. Carefully place the heatsink on top
of the installed CPU.

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.

2.3.1 DIMM sockets location
The system motherboard comes with four Double Data Rate II (DDR2) Dual Inline
Memory Modules (DIMM) sockets to support 240-pin DDR2 modules.
The gure illustrates the location of the DDR2 DIMM sockets:
2.3.2 Memorycongurations
You may install 256 MB, 512 MB, 1 GB, and 2 GB unbuffered ECC or non-ECC
DDR2-533/667 DIMMs to the DIMM sockets.
• Always install DIMMs with the same CAS latency. For optimum compatibility,
it is recommended that you obtain memory modules from the same vendor.
Visit the ASUS website for an updated DDR2 Qualied Vendors List for this
motherboard.
• Due to chipset resource allocation, and depending on the number of
expansion cards installed, the following conditions may occur:
- the system may detect less than 8 GB system memory when
you installed four 2 GB DDR2 memory modules
- may show an available memory space of less than 4 GB when
you installed four 1 GB DDR2 memory modules
• Three DDR2 DIMMs installed into any three memory sockets will function in
Dual channel asymmetric mode.
• When installing a single or two DIMMs, install the modules on the blue slots
(DIMM_A1/DIMM_B1). Refer to the recommended memory conguration
table below.

2.3.3 Installing a DIMM
Make sure 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.
To install a DIMM:
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.
3. Firmly insert the DIMM into the
socket until the retaining clips
snap back in place and the
DIMM is properly seated.
• A DDR2 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.
• The DDR2 DIMM sockets do not support DDR DIMMs. DO NOT install
DDR DIMMs to the DDR2 DIMM sockets.
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 four hot-swap Serial ATA hard disk drives. The hard disk
drive installed on the left tray connects to the motherboard SATA ports via SATA
backplane.
To install a hot-swap SATA 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.

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 SATA hard disk drive on
the tray, then secure it with four
screws.
2-11ASUS RS120-E4/PA4
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 SATA connector on the drive connects to the SATA 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 SATA drive.
8. Connect the bundled SATA cables to the connectors on the SATA backplane.
Refer to section “2.7 SATA backplane cabling” for information on the SATA
backplane cable connections.

2.5 Expansion slot
2.5.1 Installing an expansion card to the riser card bracket
The barebone server comes with a riser card bracket. You need to remove the
bracket if you want to install a PCI-X and/or a PCI Express x8 expansion cards.
To install a PCI-X card:
1. Firmly hold the riser card bracket,
then pull it up to detach it from the
PCI Express x8 and PCI-X slots on
the motherboard.
2. Place the riser card bracket on a
at and stable surface, then remove
the screw from the PCI-X slot bay.

3. Install a PCI-X card to the bracket
as shown, then secure the card
with a screw.

To install a PCI Express x8 card:
1. Follow steps 1 to 2 of the previous
section.

2. Use a Phillips (cross) screwdriver
to remove the screw that secures
the slot metal cover.
3. Remove the slot metal cover, then
set it aside.
4. Install a P CI Express x8 card to
the bracket as shown, then secure
the card with a screw you removed
earlier.
