Q87T 204-pin DDR3 DIMM sockets
1.4.2Memory configurations
You may install 1GB, 2GB, 4GB, and 8GB unbuffered non-ECC DDR3 DIMMs into the DIMM sockets.
•You may install varying memory sizes in ChannelAand 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.
•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 3GB 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.
•This motherboard does not support DIMMs made up of 512 megabits (Mb) chips or less.
•Memory modules with memory frequency higher than 2133 MHz and its corresponding timing or the loaded X.M.P. 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.
•The maximum 16GB memory capacity can be supported with 8GB or above DIMMs. ASUS will update the memory QVL once the DIMMs are available in the market.
ASUS Q87T |
1-7 |
• 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 2.5 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.
•Visit the ASUS website at: www.asus.com for the latest QVL.

1.5Expansion 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.
1.5.1Installing 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 firmly 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.
1.5.2Configuring 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.Assign an IRQ to the card.
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, conflicts will arise between the two PCI groups, making the system unstable and the card inoperable.
1.5.3PCI Express 3.0/2.0 x4 slot
This motherboard supports PCI Express x4 network cards, SCSI cards, and other cards that comply with the PCI Express specifications.

Q87T Clear RTC RAM
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 reenter 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.

3.Chassis intrusion connector (4-1 pin CHASSIS)
This connector is for a chassis-mounted intrusion detection sensor or switch. Connect one end of the chassis intrusion sensor or switch cable to this connector. The chassis intrusion sensor or switch sends a high-level signal to this connector when a chassis component is removed or replaced. The signal is then generated as a chassis intrusion event.
By default, the pins labeled “Intruder” are shorted with a jumper cap. Remove the jumper caps only when you intend to use the chassis intrusion detection feature.
