2.4 System memory

2.4.1 Overview

The motherboard comes with six Double Data Rate 3 (DDR3) Dual Inline Memory
Modules (DIMM) sockets.

A DDR3 module has the same physical dimensions as a DDR2 DIMM but is
notched differently to prevent installation on a DDR2 DIMM socket. DDR3 modules
are developed for better performance with less power consumption.

The gure illustrates the location of the DDR3 DIMM sockets:

Channel Sockets

Channel A DIMM_A1 and DIMM_A2

ASUS P6T6 WS Revolution 2-11

Sockets

DIMM_A2 DIMM_A1 DIMM_B2 DIMM_B1 DIMM_C2 DIMM_C1

Due to Intel CPU spec denition, the system will not boot if only one DIMM is

installed in DIMM slot A2, B2, or C2. Follow the table above for recommended

memory conguration.

2.4.2 Memory congurations

You may install 1GB and 2GB non-ECC, unbuffered DDR3 DIMMs into the DIMM
sockets.

• 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 conguration. Any excess memory from
the higher-sized channel is then mapped for single-channel operation.

• Due to Intel spec denition, X.M.P. DIMMs and DDR3-1600 are supported

for one DIMM per channel only.

• According to Intel CPU spec, DIMMs with voltage requirement over 1.65V
may damage the CPU permanently. We recommend you install the DIMMs
with the voltage requirement below 1.65V.

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

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 128 Mb
chips.

• The default memory operation frequency is dependent on its SPD. Under
the default state, some memory modules for overclocking may operate at a
lower frequency than the vendor-marked value.

• For system stability, use a more efcient memory cooling system to support

a full memory load (6 DIMMs) or overclocking condition.

2-12 Chapter 2: Hardware information

2.4.3 Installing a DIMM

2.5 Expansion slots

In the future, you may need to install expansion cards. The following sub-sections
describe the slots and the expansion cards that they support.

Make sure to unplug the power cord before adding or removing expansion
cards. Failure to do so may cause you physical injury and damage motherboard
components.

2.5.1 Installing an expansion card

To install an expansion card:

1. Before installing the expansion card, read the documentation that came with
it and make the necessary hardware settings for the card.

2. Remove the system unit cover (if your motherboard is already installed in a
chassis).

3. Remove the bracket opposite the slot that you intend to use. Keep the screw
for later use.

4. Align the card connector with the slot and press rmly until the card is

completely seated on the slot.

5. Secure the card to the chassis with the screw you removed earlier.

6. Replace the system cover.

2.5.2 Conguring an expansion card

After installing the expansion card, congure it by adjusting the software settings.

1. Turn on the system and change the necessary BIOS settings, if any. See
Chapter 3 for information on BIOS setup.

2. Assign an IRQ to the card. Refer to the tables on the next page.

3. Install the software drivers for the expansion card.

When using PCI cards on shared slots, ensure that the drivers support “Share

IRQ” or that the cards do not need IRQ assignments. Otherwise, conicts will

arise between the two PCI groups, making the system unstable and the card
inoperable. Refer to the table on the next page for details.

gure below for the location of the slots.

PCIe 2.0 x16_1 slot
(at x16 or x8 mode)

PCIe 2.0 x16_2 slot
(at x8 mode)

PCIe 2.0 x16_4 slot (at x8 mode)

PCIe 2.0 x16_3 slot (at x16 or x8 mode)

PCIe 2.0 x16_6 slot (at x4 mode)

PCIe 2.0 x16_5 slot (at x16 mode)

• In single VGA card mode, use rst the PCIe 2.0 x16_1 slot for a PCI

Express x16 graphics card to get better performance.

• In CrossFireX™ mode, use the PCIe 2.0 x16_1 and PCIe 2.0 x16_3 (or
PCIe 2.0 x16_5) slots for PCI Express x16 graphics carsds to get better
performance.

• In 2-Way SLI™ mode, use the PCIe 2.0 x16_1 and PCIe 2.0 x16_5 slots for
PCI Express x16 graphics cards to get better performance.

• In 3-Way SLI™ mode, use the PCIe 2.0 x16_1, PCIe 2.0 x16_3 and
PCIe 2.0 x16_5 slots for PCI Express x16 graphics cards to get better
performance.

• When using the PCIe 2.0 x16_1, PCIe 2.0 x16_3 and PCIe 2.0 x16_5 slots
for 3-Way SLI™ mode, the three slots will work at x16 link while PCIe 2.0
x16_2 and PCIe 2.0 x16_4 slots are not occupied.

• We recommend that you provide sufcient power when running

CrossFireX™ or SLI™ mode. See page 2-30 for details.

• Connect a chassis fan to the motherboard connector labeled
CHA_FAN1/2/3 when using multiple graphics cards for better thermal

2.6 Jumpers

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.

• 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 behavior, AC power off is required to enable C.P.R.
function. You must turn off and on the power supply or unplug and plug the
power cord before rebooting the system.

2-20 Chapter 2: Hardware information

2. CPU / DRAM Bus / QPI DRAM overvoltage setting (3-pin OV_CPU, 3-pin
OV_DRAM_BUS, 3-pin OV_QPI_DRAM)

These jumpers allow you to enable or disable the advanced CPU, DRAM
Bus, and QPI DRAM overvoltage settings in BIOS. Read the following
information before you change the jumper settings.

OV_CPU OV_DRAM_BUS OV_QPI_DRAM

Pins 1-2 (Default) up to 1.70V up to 1.90V up to 1.70V

Pins 2-3 (OV Enabled) up to 1.9V up to 2.46V up to 1.9V

• Before you change the jumper settings for extra-high overvoltage ability,

use the BIOS items rst to adjust the desired CPU, DRAM, and QPI

performance. Make sure your system functions well under the highest BIOS
voltage settings before you change the setting of these three jumpers.

• DO NOT set the OV_CPU jumper to pins 2–3 when you install a new CPU

and have not booted for the rst time. Doing so may cause the system to

halt. For system failure due to the wrong setting of the OV_CPU jumper,
shut down the computer and move the cap back to pins 1–2.

• According to Intel CPU spec, DIMMs with voltage requirement over 1.65V
may damage the CPU permanently. We recommend you install the DIMMs
with the voltage requirement below 1.65V.

• The system may need a better cooling system (for example, a water­cooling system) to work stably under high voltage settings.

3-8 Chapter 3: BIOS setup

3.2 BIOS setup program

This motherboard supports a programmable rmware chip that you can update

using the provided utility described in section 3.1 Managing and 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
rmware chip.

The rmware 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.

• 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 3.9 Exit Menu.

• The BIOS setup screens shown in this section are for reference purposes
only, and may not exactly match what you see on your screen.

• Visit the ASUS website (www.asus.com) to download the latest BIOS le for

this motherboard.
