Hardware Setup

CPU (Central Processing Unit)

When you are installing the CPU, make sure to install the cooler to prevent
overheating. If you do not have the CPU cooler, consult your dealer before turning

on the computer.
For the latest information about CPU, please visit http://global.msi.com.tw/index.php?

func=cpuform2

Important

Overheating

Overheating will seriously damage the CPU and system. Always make sure
the cooling fan can work properly to protect the CPU from overheating. Make
sure that you apply an even layer of thermal paste (or thermal tape) between
the CPU and the heatsink to enhance heat dissipation.

Replaceing the CPU

While replacing the CPU, always turn off the ATX power supply or unplug the
power supply’s power cord from the grounded outlet first to ensure the safety
of CPU.

Overclocking

This mainboard is designed to support overclocking. However, please make
sure your components are able to tolerate such abnormal setting, while
doing overclocking. Any attempt to operate beyond product specifications is
not recommended. We do not guarantee the damages or risks caused

by inadequate operation or beyond product specifications.

Important

-DDR3 memory modules are not interchangeable with DDR2 and the DDR3

standard is not backwards compatible. You should always install DDR3
memory modules in the DDR3 DIMM slots.

-In Three/ Dual-Channel mode, make sure that you install memory modules of

the same type and density in different channel DIMM slots.

-To enable successful system boot-up, always insert the memory modules

into the DIMM_A0 first.

- Due to the chipset resource deployment, the system density will only be

detected up to 23+GB (not full 24GB) when each DIMM is installed with a 4GB
memory module.

- When you install incorrect memory module (the SA2-pin of the memory

module connects to Ground) in the DIMM_C0/C1, the LED beside DIMM_C0
will light red color to remind you. The position of the LED is shown as below.
Double confirm with your memory module vender for the third channelsupports.

ATI CrossFireXTM (Multi-GPU) Technology

ATI CrossFireXTM (Multi-GPU) technology is an exciting new technology developed by
ATI that allows the power of multiple Graphics. CrossFireX requires a CrossFireX
Edition graphics card and the compatible standard (CrossFireX Ready) graphics card
from the same series. To utilize this technology, always install the CrossFireX Edition
graphics card in the First PCIE x16 (PCI_E2) slot and install the CrossFireX Ready
graphics card in the Second PCIE x16 (PCI_E5) slot. The mainboard can auto detect
the CrossFireX mode by software, therefore you don’t have to enable the CrossFireX
in BIOS by yourself. Following the process below to complete CrossFireX:

1. Install the CrossFire Edition graphics card in the First PCIE x16 (PCI_E2) slot and
install the CrossFire Ready graphics card in the Second PCIE x16 (PCI_E5) slot.

2. With two cards installed, an CrossFire Video Link cable is required to connect the
golden fingers on the top of these two graphics cards (refer to the picture below).
Please note that although you have installed two graphics cards, only the video
outputs on the CrossFire Edition graphics card will work. Hence, you only need to
connect a monitor to the CrossFire Edition graphics card.

CrossFire Video Link cable

Important

1. Mainboard photos shown in this section are for demonstration only. The
appearance of your mainboard may vary depending on the model you purchase.

2. If you intend to install TWO graphics cards for CrossFireX mode, make
sure that:

According to the Inte CPU spec, DRAM Voltage setting 1.65V may damage the CPU
permanently. It is strongly recommended that you install the DRAM with the voltage
setting below 1.65V. You can read the DRAM voltage in GreenPower Center.

Spread Spectrum

When the motherboard’s clock generator pulses, the extreme values (spikes) of the
pulses create EMI (Electromagnetic Interference). The Spread Spectrum function
reduces the EMI generated by modulating the pulses so that the spikes of the pulses
are reduced to flatter curves. If you do not have any EMI problem, leave the setting at
Disabled for optimal system stability and performance. But if you are plagued by EMI,
set to Enabled for EMI reduction. Remember to disable Spread Spectrum if you are
overclocking because even a slight jitter can introduce a temporary boost in clock
speed which may just cause your overclocked processor to lock up.

3-25

MS-7522 Mainboard

Important

1.If you do not have any EMI problem, leave the setting at [Disabled] for
optimal system stability and performance. But if you are plagued by EMI,
select the value of Spread Spectrum for EMI reduction.

2.The greater the Spread Spectrum value is, the greater the EMI is reduced,
and the system will become less stable. For the most suitable Spread
Spectrum value, please consult your local EMI regulation.

3.Remember to disable Spread Spectrum if you are overclocking because
even a slight jitter can introduce a temporary boost in clock speed which
may just cause your overclocked processor to lock up.
