1.4.1 Overview

This motherboard comes with four Double Data Rate 3 (DDR3) Dual Inline Memory Module (DIMM) sockets. 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.

ASUS H81-GAMER - Overview - 1

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

H81-GAMER 240-pin DDR3 DIMM sockets

1.4.2 Memory configurations

You may install 1 GB, 2 GB, 4 GB, and 8 GB unbuffered non-ECC DDR3 DIMMs into the DIMM sockets. You can refer to the recommended memory population below.

DIMM_A2, DIMM_A2, DIMW_B2, DIMM_A1, DIMM_A2, DIMM_B1, DIMM_B2

	SS: Single-sided memory DS: Double-sided memory

ASUS H81-GAMER - Memory configurations - 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 configuration. Any excess memory from the higher-sized channel is then mapped for single-channel operation.
Due to Intel® chipset limitation, DDR3 1600 MHz and higher memory modules on XMP mode will run at the maximum transfer rate of DDR3 1600 MHz.
Due to Intel® chipset limitation, this motherboard can only support single-sided memories when four modules are installed and they will run at the maximum transfer rate of DDR3 1066MHz.
Always install DIMMs with the same CAS latency. For optimal compatibility, we recommend that you install memory modules of the same version or date code (D/C) from the same vendor. Check with the retailer to get the correct memory modules.
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 3 GB system memory if you are using a 32-bit Windows OS.
Install a 64-bit Windows® OS if 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 512 Mb (64 MB) chips or less.

ASUS H81-GAMER - Memory configurations - 3

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.
For system stability, use a more efficient memory cooling system to support a full memory load (4 DIMMs).
Visit the ASUS website at www.asus.com for the latest QVL.

1.4.3 Installing a DIMM

ASUS H81-GAMER - Installing a DIMM - 1

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.
Plug the power cord and turn ON the computer.
Hold down the key during the boot process and enter BIOS setup to re-enter data.

ASUS H81-GAMER - To erase the RTC RAM: - 1

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

ASUS H81-GAMER - To erase the RTC RAM: - 2

If the steps above do not help, remove the onboard battery and move the jumper again to clear the CMOS RTC RAM data. After clearing the CMOS, 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 CPU Parameter Recall (C.P.R.) feature. Shut down and reboot the system, then the BIOS automatically resets parameter settings to default values.
