System memory

Overview
The motherboard comes with four Double Data Rate (DDR) Dual Inline Memory Modules (DIMM) sockets.

104 Pins 80 Pins

DIMM_B4 DIMM_A4 DIMM_B3 DIMM_A3 DIMM_B2 DIMM_A2 DIMM_B1 DIMM_A1
NCL-DS1R1 184-pin DDR DIMM sockets

Memory configurations

You may install 256 MB, 512 MB, 1 GB, and 2 GB registered ECC DDR DIMMs into 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. Refer to the DDR Qualified Vendors List on the ASUS website for details. Due to chipset resource allocation, the system may detect less than 16 GB system memory when you install eight 2 GB DDR memory modules. Three DDR DIMMs intalled into any three memory sockets will function in single-channel mode. If installing only one pair of DIMMs, install them in sockets DIMM_B4 and DIMM_A4.

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. 2
Unlock a DIMM socket by pressing the retaining clips outward. Align a DIMM on the socket such that the notch on the DIMM matches the break on the socket.

DDR DIMM notch

Unlocked retaining clip
A DDR DIMM is keyed with a notch so that it fits in only one direction. DO NOT force a DIMM into a socket to avoid damaging the DIMM.
Firmly insert the DIMM into the socket until the retaining clips snap back in place and the DIMM is properly seated.

Locked Retaining Clip

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 fingers when pressing the retaining clips. The DIMM might get damaged when it flips out with extra force.
Remove the DIMM from the socket.

If you have the rackmount rail kit, it contains two pairs of rails (one pair for each side of the barebone system), and eight (8) pairs of nut-and-bolt type screws.

Except when clearing the RTC RAM, never remove the cap on CLRTC jumper default position. Removing the cap will cause system boot failure!

CLRTC1

Normal (Default) Clear CMOS

NCL-DS1R1 Clear RTC RAM

CPU fan pin selection (3-pin FM_CPU1, FM_CPU2) These jumpers allow you to connect either a 3-pin or a 4-pin CPU fan cable plug to the CPU fan connectors (CPU_FAN1, CPU_FAN2). Set these jumpers to pins 1-2 if you are using a 3-pin fan cable plug, or to pins 2-3 if you are using a 4-pin plug.

DC mode (Default) PWM

NCL-DS1R1 FM_CPU setting
USB device wake-up (3-pin USBPW12, USBPW34) Set these jumpers to +5V to wake up the computer from S1 sleep mode (CPU stopped, DRAM refreshed, system running in low power mode) using the connected USB devices. Set to +5VSB to wake up from S3 and S4 sleep modes (no power to CPU, DRAM in slow refresh, power supply in reduced power mode).

+5V (Default)

+5V (Default) +5VSB
NCL-DS1R1 USB device wake up
The USB device wake-up feature requires a power supply that can provide 500mA on the +5VSB lead for each USB port; otherwise, the system would not power up. The total current consumed must NOT exceed the power supply capability (+5VSB) whether under normal condition or in sleep mode.
Keyboard power (3-pin KBPWR1) This jumper allows you to enable or disable the keyboard wake-up feature. Set this jumper to pins 2-3 (+5VSB) to wake up the computer when you press a key on the keyboard (the default is the Space Bar). This feature requires an ATX power supply that can supply at least 1A on the +5VSB lead, and a corresponding setting in the BIOS.
