Chapter 2: Hardware information
2.1 Before you proceed
Take note of the following precautions before you install motherboard components or change
any motherboard settings.
• Unplug the power cord from the wall socket before touching any component.
• Before handling components, use a grounded wrist strap or touch a safely grounded
object or a metal object, such as the power supply case, to avoid damaging them due
to static electricity.
• Hold components by the edges to avoid touching the ICs on them.
• Whenever you uninstall any component, place it on a grounded antistatic pad or in the
bag that came with the component.
• Before you install or remove any component, ensure that the ATX power supply is
switched off or the power cord is detached from the power supply. Failure to do so
may cause severe damage to the motherboard, peripherals, or components.

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.

Memory congurations
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 and Channel B. The system maps
the total size of the lower-sized channel for the dual-channel conguration. 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 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 efcient memory cooling system to support a full
Side(s): SS - Single-sided DS - Double-sided
DIMM support:
• 1 DIMM: Supports one (1) module inserted into any slot as Single-channel memory
conguration.
We suggest that you install the module into A2 slot
.
• 2 DIMMs: Supports two (2) modules inserted into either the blue slots or the black
slots as one pair of Dual-channel memory conguration.
you install the modules into slots A2 and B2 for better compatibility
We suggest that

• 4 DIMMs: Supports four (4) modules inserted into both the blue and black slots as two
pairs of Dual-channel memory conguration.
• ASUS exclusively provides hyper DIMM support function.
• Hyper DIMM support is subject to the physical characteristics of individual CPUs. Load
the X.M.P. or D.O.C.P. settings in the BIOS for the hyper DIMM support.
