System memory  
Overview  
1.5.1  
The motherboard comes with four 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 figure illustrates the location of the DDR3 DIMM sockets:

Channel B  
DIMM_A1 and DIMM_A2  
DIMM_B1 and DIMM_B2  
F2A85-M2  
F2A85-M2 240-pin DDR3 DIMM sockets  
1.5.2  
Memory configurations  
You may install 1GB, 2GB, 4GB, and 8GB unbuffered non-ECC DDR3 DIMMs into the DIMM  
sockets.  
Memory module with memory frequency higher than 2133 MHz and its corresponding  
timing or the loaded XMP Profile is not the JEDEC memory standard. The stability and  
compatibility of these memory modules depend on the CPU’s capabilities and other  
installed devices.  
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.  
We recommend that you install the memory modules from the blue slots for better  
overclocking capability.  
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:  
-
Install a maximum of 3GB system memory if you are using a 32-bit Windows®  
OS.  
-
Use a 64-bit Windows® OS if you want to install 4GB or more memory on the  
motherboard.  
This motherboard does not support DIMMs made up of 512Mb (64MB) chips or less.  
The maximum 64GB memory capacity can be supported with 16GB or above DIMMs.  
ASUS will update the memory QVL once the DIMMs are available in the market.  
1-11  
ASUS F2A85-M2  
 
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 2.4 Ai Tweaker menu for manual memory  
frequency adjustment.  
For system stability, use a more efficient memory cooling system to support a full  
memory load (4 DIMMs) or overclocking condition.

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.  
Unplug the power cord before adding or removing expansion cards. Failure to do so may  
cause you physical injury and damage motherboard components.  
1.6.1  
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.  
3.  
Remove the system unit cover (if your motherboard is already installed in a chassis).  
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 firmly until the card is completely  
seated on the slot.  
5.  
6.  
Secure the card to the chassis with the screw you removed earlier.  
Replace the system cover.  
1.6.2  
Configuring an expansion card  
After installing the expansion card, configure it by adjusting the software settings.  
1.  
Turn on the system and change the necessary BIOS settings, if any. See Chapter 2 for  
information on BIOS setup.  
2.  
3.  
Assign an IRQ to the card.  
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, conflicts will arise between the two PCI  
groups, making the system unstable and the card inoperable.  
1.6.3  
PCI slot  
The PCI slot supports cards such as a LAN card, SCSI card, USB card, and other cards that  
comply with PCI specifications.  
1.6.4

Jumpers  
Clear RTC RAM (3-pin 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.

Normal  
Clear RTC  
(Default)  
F2A85-M2 Clear RTC RAM  
To erase the RTC RAM:  
1.  
2.  
Turn OFF the computer and unplug the power cord.  
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.  
4.  
Plug the power cord and turn ON the computer.  
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 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.
