Generation Core™ i7 / Core™ i5 / Core™ i3, Pentium™, and Celeron™ processors.
H87-PLUS
H87-PLUS CPU socket LGA1150
•
•
Ensure that all power cables are unplugged before installing the CPU.
Ensure that you install the correct CPU designed for LGA1150 only. DO NOT install a
CPU designed for LGA1155 and LGA1156 sockets on the LGA1150 socket.
•
Upon purchase of the motherboard, ensure that the PnP cap is on the socket and
the socket contacts are not bent. Contact your retailer immediately if the PnP cap
is missing, or if you see any damage to the PnP cap/socket contacts/motherboard
components. ASUS will shoulder the cost of repair only if the damage is shipment/
transit-related.
•
•

Recommended memory configurations
1-10
Chapter 1: Product introduction
Memory configurations
You may install 1GB, 2GB, 4GB, and 8GB unbuffered and non-ECC DDR3 DIMMs into the
DIMM sockets.
•
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.
•
•
•
•
According to Intel CPU specification, DIMM voltage below 1.65V is recommended to
protect the CPU.
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.
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:
a) Use a maximum of 3GB system memory if you are using a 32-bit Windows® OS.
b) Install a 64-bit Windows® OS when you want to install 4GB or more on the
motherboard.
c) 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 3.5 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.
•
Always install the DIMMS with the same CAS Latency. For an optimum compatibility,
we recommend that you install memory modules of the same version or data code (D/
C) from the same vendor. Check with the vendor to get the correct memory modules.

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.
To erase the RTC RAM:
H87-PLUS

Clear RTC
(Default)
H87-PLUS Clear 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 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 so the BIOS can automatically reset parameter
settings to default values.

Onboard buttons
Onboard buttons allow you to fine-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.
MemOK! button
Installing DIMMs that are not compatible with the motherboard may cause system boot
failure, and the DRAM_LED near the MemOK! switch lights continuously. Press and hold the
MemOK! button until the DRAM_LED starts blinking to begin automatic memory compatibility
tuning for successful boot.
H87-PLUS
H87-PLUS MemOK! button
•
•
Refer to section 1.2.8 Onboard LEDs for the exact location of the DRAM_LED.
The DRAM_LED also lights up when the DIMM is not properly installed. Turn off the
system and reinstall the DIMM before using the MemOK! function.
•
•
The MemOK! switch does not function under Windows® OS environment.
During the tuning process, the system loads and tests failsafe memory settings. It
takes about 30 seconds for the system to test one set of failsafe settings. If the test
fails, the system reboots and test the next set of failsafe settings. The blinking speed
of the DRAM_LED increases, indicating different test processes.
•
Due to memory tuning requirement, the system automatically reboots when each
timing set is tested. If the installed DIMMs still fail to boot after the whole tuning
process, the DRAM_LED lights continuously. Replace the DIMMs with ones
recommended in the Memory QVL (Qualified Vendors Lists) in this user manual or on
the ASUS website at www.asus.com.
•
•
•
If you turn off the computer and replace DIMMs during the tuning process, the system
continues memory tuning after turning on the computer. To stop memory tuning, turn
off the computer and unplug the power cord for about 5–10 seconds.
If your system fails to boot up due to BIOS overclocking, press the MemOK! switch
to boot and load the BIOS default settings. A message will appear during POST
reminding you that the BIOS has been restored to its default settings.
We recommend that you download and update to the latest BIOS version from the
ASUS website at www.asus.com after using the MemOK! function.

Knowing BIOS
The new ASUS UEFI BIOS is a Unified Extensible Interface that complies with UEFI
architecture, offering a user-friendly interface that goes beyond the traditional keyboard-
only BIOS controls to enable a more flexible and convenient mouse input. You can easily
navigate the new UEFI BIOS with the same smoothness as your operating system. The
term “BIOS” in this user manual refers to “UEFI BIOS” unless otherwise specified.
BIOS (Basic Input and Output System) stores system hardware settings such as storage
device configuration, overclocking settings, advanced power management, and boot
device configuration that are needed for system startup in the motherboard CMOS. In
normal circumstances, the default BIOS settings apply to most conditions to ensure
optimal performance. DO 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 BIOS settings may result to instability or boot failure. We strongly
recommend that you change the BIOS settings only with the help of a trained service
personnel.
When downloading or updating the BIOS file, rename it as H87PLUS.CAP for this
motherboard.
