2.4.1 Overview

The motherboard comes with six fully-buffered DIMM (FB-DIMM) sockets to support 240-pin FB-DIMM modules. An FB-DIMM module has a different pin-out from DDR2 DIMMs so you cannot install DDR2 DIMMs on an FB-DIMM socket. Note that an FB-DIMM socket has an Advanced Memory Buffer (AMB) chip that allows memory-to-CPU connection at gigabit speed.
The gure illustrates the location of the FB-DIMM sockets:
2.4.2 Memory congurations
You may install 256 MB, 512 MB, 1 GB, 2 GB, and 4 GB registered ECC FB-DIMMs into the DIMM sockets.
For optimum compatibility, we recommend that you obtain memory modules
from the same vendor. Refer to the Qualied Vendors List on the ASUS
web site.
This motherboard does not support memory modules made up of 128 Mb chips or double-rank x16 memory modules.
If you are installing only one memory module, install into the white socket labeled DIMM_00. Installing into any other socket will not work.

2.4.3 Memory sparing technology

The Intel® Seaburg chipset supports the memory sparing technology. Refer to theurg chipset supports the memory sparing technology. Refer to the chipset supports the memory sparing technology. Refer to the below sections:
Memory Sparing :
At conguration time, a DIMM rank is set aside to replace a defective DIMM rank.
When the error rate for a failing DIMM rank reaches a pre-determined threshold, the memory sparing function will issue an interrupt and initiate a spare copy. At the completion of the copy, the failing DIMM rank is disabled and the “spared” DIMM rank will be used in its place.
The DIMM rank with the largest size will be assigned as spare rank. Data can only be copied from a smaller sized rank to a larger sized one.
A DIMM can contain only one or two ranks. To support sparing function, a DIMM channel should contain at least two ranks.
When sparing function is enabled, the usable memory size will reduce then size of the spare ranks.
2-16 Chapter 2: Hardware information
Page 39

2.4.4 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 FB-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 FB-DIMM sockets do not support DDR DIMMs. DO NOT install DDR DIMMs to the FB-DIMM sockets.

2.4.5 Removing a DIMM

To remove a DIMM:
1. Simultaneously press the retaining clips outward to unlock the DIMM.

1. Clear RTC RAM (CLRTC)
This jumper allows you to clear the Real Time Clock (RTC) RAM in CMOS. You can clear the CMOS memory of date, time, and system setup parameters by erasing the CMOS RTC RAM data. The onboard button cell battery powers the RAM data in CMOS, which include system setup information such as system passwords.
To erase the RTC RAM:
1. Turn OFF the computer and unplug the power cord.
2. Move the jumper cap from pins 1-2 (default) to pins 2-3. Keep the cap on pins 2-3 for about 5~10 seconds, then move the cap back to pins 1-2.
3. Plug the power cord and turn ON the computer.
4. Hold down the <Del> key during the boot process and enter BIOS setup to re-enter data.
Except when clearing the RTC RAM, never remove the cap on CLRTC jumper default position. Removing the cap will cause system boot failure!
If the steps above do not help, remove the onboard battery and move the jumper again to clear the CMOS RTC RAM data. After the CMOS clearance, reinstall the battery.
ASUS Z7S WS 2-23
You do not need to clear the RTC when the system hangs due to overclocking. For system failure due to overclocking, use the C.P.R. (CPU Parameter Recall) feature. Shut down and reboot the system so the BIOS can automatically reset parameter settings to default values.
Due to the chipset limitation, AC power off is required prior using C.P.R. function. You must turn off and on the power supply or unplug and plug the power cord before reboot the system.

These connectors are for SSI power supply plugs. The power supply plugs
are designed to t these connectors in only one orientation. Find the proper orientation and push down rmly until the connectors completely t.
For a fully congured system, we recommend that you use a power supply unit (PSU) that complies with ATX 12 V Specication 2.0 (or later version)
and provides a minimum power of 600 W.
Do not forget to connect the 8-pin EATX12V power plug; otherwise, the
system will not boot.
If you install only one CPU on the CPU0 socket, you can connect only the EATXPWR and EATX12V power connectors to boot the system.
Use of a PSU with a higher power output is recommended when conguring
a system with more power-consuming devices. The system may become unstable or may not boot up if the power is inadequate.
If you want to use two high-end PCI Express x16 cards, use a PSU with 600W power or above to ensure the system stability.
If you are uncertain about the minimum power supply requirement for your system, refer to the at http://support.asus.com/PowerSupplyCalculator/PSCalculator. aspx?SLanguage=en-us for details.

4.2 BIOS setup program

This motherboard supports a programmable Low-Pin Count (LPC) chip that you can update using the provided utility described in section
updating your BIOS
.
Use the BIOS Setup program when you are installing a motherboard, reconguring your system, or prompted to “Run Setup.” This section explains how to congure
your system using this utility.
Even if you are not prompted to use the Setup program, you can change the
conguration of your computer in the future. For example, you can enable the
security password feature or change the power management settings. This
requires you to recongure your system using the BIOS Setup program so that the computer can recognize these changes and record them in the CMOS RAM of the
LPC chip.
The LPC chip on the motherboard stores the Setup utility. When you start up the computer, the system provides you with the opportunity to run this program. Press
<Del> during the Power-On Self-Test (POST) to enter the Setup utility; otherwise,
POST continues with its test routines.
If you wish to enter Setup after POST, restart the system by pressing <Ctrl+Alt+Delete>, or by pressing the reset button on the system chassis. You can also restart by turning the system off and then back on. Do this last option only if
the rst two failed.
The Setup program is designed to make it as easy to use as possible. Being a menu-driven program, it lets you scroll through the various sub-menus and make your selections from the available options using the navigation keys.
4.1 Managing and
The default BIOS settings for this motherboard apply for most conditions to ensure optimum performance. If the system becomes unstable after changing any BIOS settings, load the default settings to ensure system compatibility and stability. Select the Load Setup Defaults item under the Exit Menu. See section
The BIOS setup screens shown in this section are for reference purposes only, and may not exactly match what you see on your screen.
