CPU & Cooler Installation

When you are installing the CPU, make sure the CPU has a cooler attached on
the top to prevent overheating. Meanwhile, do not forget to apply some thermal

paste on CPU before installing the heat sink/cooler fan for better heat dispersion.
Follow the steps below to install the CPU & cooler correctly. Wrong installation will
cause damage to your CPU & mainboard.

1.The CPU socket has a plastic cap on

it to protect the contact from damage.
Before you install the CPU, always
cover it to protect the socket pin.

2.Remove the cap from lever hinge
side (as the arrow shows).

4.Open the load lever.3.The pins of socket reveal.

2-3

MS-9828 Mainboard

5.Lift the load lever up and open the
load plate.

7.Visually inspect if the CPU is
seated well into the socket. If not,
take out the CPU with pure vertical
motion and reinstall.

6.After confirming the CPU direction
for correct mating, put down the
CPU in the socket housing frame.
Be sure to grasp on the edge of
the CPU base. Note that the align­ment keys are matched.

9.Press down the load lever lightly
onto the load plate, and then se­cure the lever with the hook under
retention tab.

11.Press the four hooks down to fasten

the cooler. Then rotate the locking
switch (refer to the correct direction
marked on it) to lock the hooks.

10. Align the holes on the mainboard
with the heatsink. Push down the
cooler until its four clips get
wedged into the holes of the
mainboard.

12.Turn over the mainboard to con­firm that the clip-ends are correctly
inserted.

Installing Memory Modules

1. Locate the DIMM slots on the mainboard. Flip open the retaining clip at each side
of the DIMM slot.

2. Align the notch on the DIMM with the key on the slot. Insert the DIMM vertically into
the DIMM slot. Then push it in until the golden finger on the DIMM is deeply inserted
in the DIMM slot. The retaining clip at each side of the DIMM slot will automatically
close if the DIMM is properly seated.

Important

You can barely see the golden finger if the DIMM is properly inserted in the
DIMM slot.

3. Manually check if the DIMM has been locked in place by the retaining clips at the
sides.

4. Follow the same procedures to install more DIMMs if necessary.

CPU Feature

Execute Bit Support

Intel's Execute Disable Bit functionality can prevent certain classes of malicious
"buffer overflow" attacks when combined with a supporting operating system.
This functionality allows the processor to classify areas in memory by where
application code can execute and where it cannot. When a malicious worm
attempts to insert code in the buffer, the processor disables code execution,
preventing damage or worm propagation.

TM2

Thermal Management throttles the processor back as it reaches its maximum
operating temperature. Throttling reduces the number of processing cycles,
thereby diminishing the heat dissipation of the CPU. This cools the unit. Once the
CPU has reached a safe operating temperature, thermal throttling is automati­cally disabled, and normal full speed processing begins again.

IRQ Resource Setup

BIOS Setup

IRQ 3/4/5/7/9/10/11/14/15

These items specify the bus where the specified IRQ line is used.
The settings determine if AMIBIOS should remove an IRQ from the pool of
available IRQs passed to devices that are configurable by the system BIOS. The
available IRQ pool is determined by reading the ESCD NVRAM. If more IRQs must
be removed from the IRQ pool, the end user can use these settings to reserve
the IRQ by assigning an [Reserved] setting to it. Onboard I/O is configured by
AMIBIOS. All IRQs used by onboard I/O are configured as [Available]. If all IRQs
are set to [Reserved], and IRQ 14/15 are allocated to the onboard PCI IDE, IRQ 9
