Authorization (RMA) requests only if the motherboard comes with the cap on the

LGA2011 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.

2-4 Chapter 2: Hardware information

2.2.3 System memory

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

A DDR3 module is notched differently from a DDR or DDR2 module. DO NOT install a DDR
or DDR2 memory module to the DDR3 slot.

Recommended memory congurations

Chapter 2

ROG RAMPAGE IV FORMULA 2-5

Memory congurations

You may install 1GB, 2GB, 4GB and 8GB unbuffered and non-ECC DDR3 DIMMs into the
DIMM sockets.

Chapter 2

• You may install varying memory sizes in Channel A, Channel B, Channel C and
Channel D. The system maps the total size of the lower-sized channel for the dual­channel, triple-channel and quad-channel conguration. Any excess memory from the
higher-sized channel is then mapped for single-channel operation.

• Due to CPU behavior, DDR3 2200/2000/1800 MHz memory module will run at DDR3
2133/1866/1600 MHz frequency as default.

• According to Intel® spec, the max. 32GB memory capacity can be supported with
DIMMs of 8GB (or above). ASUS will update QVL once the DIMMs are available on
the market.

• According to Intel CPU spec, DIMM voltage below 1.65V is recommended to protect
the CPU.

• 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 do any of the
following:

- Use a maximum of 3GB system memory if you are using a 32-bit Windows OS.

- Install a 64-bit Windows OS when you want to install 4GB or more on the

motherboard.
For more details, refer to the Microsoft® support site at
http://support.microsoft.com/kb/929605/en-us.

• This motherboard does not support DIMMs made up of 512Mb (64MB) chips or less
(Memory chip capacity counts in Megabit, 8 Megabit/Mb = 1 Megabyte/MB).

• The default memory operation frequency is dependent on its Serial Presence Detect
(SPD), which is the standard way of accessing information from a memory module.
Under the default state, some memory modules for overclocking may operate at a
lower frequency than the vendor-marked value. To operate at the vendor-marked or at
a higher frequency, refer to section
frequency adjustment.

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

memory load (4 DIMMs) or overclocking condition.

2.2.5 Onboard switches

Onboard switches allow you to ne-tune performance when working on a bare or open-

case system. This is ideal for overclockers and gamers who continually change settings to
enhance system performance.

1. Power-on switch

Press the power-on switch to wake/power up the system.

Chapter 2

2. Reset switch

Press the reset switch to reboot the system.

2-14 Chapter 2: Hardware information

3. GO button

Press the GO button before POST to enable MemOK! or press it to quickly load the

preset prole (GO_Button le) for temporary overclocking when in OS.

4. BIOS button

The motherboard comes with two BIOS. Press the BIOS button to switch BIOS and

load different BIOS settings. The nearby BIOS LEDs indicate the BIOS you are using.

Chapter 2

ROG RAMPAGE IV FORMULA 2-15

5. PCIe x16 Lane switch

These slide switches allows you to enable and disable the corresponding PCIe x16

slots. When one of the installed PCIe x16 cards is out of order, you can use the slide

switch to nd out the faulty one without removing the cards.

Chapter 2

6. Q reset button

If the LN2_Mode jumper does not work and your CPU cannot resume function, press

the Q reset button to temporarily stop the power supply to the CPU and help the CPU

recover from a frozen condition.

2-16 Chapter 2: Hardware information

7. Slow Mode Switch

Slow Mode Switch is employed during LN2 benching. Some processors have a small

optimum temperature range to run at their highest frequency. Warmer or colder yields

instability at this frequency. For example, a certain processor may need -80C loaded
in order to run 5.8GHz, which means about -75C idle in order to stay stable at 5.8GHz.

Going colder or warmer crashes. It will however remain stable at slower frequencies

at much colder or warmer temperatures. Once it comes out of a heavy load while
transitioning over to a light load, when the temperature does not warm fast enough,
it may crash. To over-come this simply flip the switch over to “slow” the processor
instantaneously. Switching over to Slow-Mode during critical moments when
Temperature/Max Frequency alignment is off-synch saves you a lot of crashes, even
when trying to boot into the OS at cold temperatures.

The Slow mode switch is workable only when LN2 mode jumper is been set to enable.
(please see 2-26)

ATX power button. If your monitor complies with the “green” standards or if it has a
“power standby” feature, the monitor LED may light up or change from orange to green

Chapter 2

after the system LED turns on.

The system then runs the power-on self tests or POST. While the tests are running, the

BIOS beeps (refer to the BIOS beep codes table below) or additional messages appear
on the screen. If you do not see anything within 30 seconds from the time you turned
on the power, the system may have failed a power-on test. Check the jumper settings
and connections or call your retailer for assistance.

Chapter 3: BIOS setup

3.1 Knowing BIOS

The new ASUS UEFI BIOS is an Unied Extensible Firmware Interface that complies with

UEFI architecture, offering a user-friendly interface that goes beyond traditional keyboard-

only BIOS controls to enable more exible and convenient mouse input. Users can easily

navigate the new UEFI BIOS with the same smoothness as their operating system. The

term “BIOS” in this user manual refers to “UEFI BIOS” unless otherwise specied.

BIOS (Basic Input and Output System) stores system hardware settings such as storage

device conguration, overclocking settings, advanced power management, and boot device
conguration that are needed for system startup in the motherboard CMOS. In normal

circumstances, the default BIOS settings apply to most conditions to ensure optimum
performance. We recommend that you not change the default BIOS settings except in
the following circumstances:

• An error message appears on the screen during the system bootup and requests you to
run the BIOS Setup.

• You have installed a new system component that requires further BIOS settings or
update.

Inappropriate settings of the BIOS may result to instability or failure to boot. We strongly

recommend that you change the BIOS settings only with the help of a trained service
personnel.

3.2 BIOS setup program

A BIOS setup program is provided for BIOS item modication. 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, press <Ctrl> + <Alt> + <Delete>, or press the reset
button on the system chassis to restart the system. You can also turn the system off and then

turn it back on to restart the system. Do this last option only if the rst two failed.

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

• Ensure that a USB mouse is connected to your motherboard if you want to use the
mouse to control the BIOS setup program.

• If the system becomes unstable after changing any BIOS setting, load the default
settings to ensure system compatibility and stability. Select the Load Optimized
Defaults item under the Exit menu. See section 3.9 Exit Menu for details.

• If the system fails to boot after changing any BIOS setting, try to clear the CMOS
and reset the motherboard to the default value. See sectionSee section 2.3.10 Rear Panel
connection for information on how to erase the RTC RAM.

The BIOS 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 submenus and select from the
available options using a keyboard or a USB mouse.

The BIOS setup program can be used under two modes: EZ Mode and Advanced Mode.
You can change modes from the Exit menu or from the Exit/Advanced Mode button in the
EZ Mode/Advanced Mode screen.
