Channel A: DIMM1 & DIMM2 (green)
Channel B: DIMM3 & DIMM4 (purple)
Introduction to DDR SDRAM
DDR (Double Data Rate) SDRAM is similar to conventional SDRAM,
but doubles the rate by transferring data twice per cycle. It uses 2.5 volts as
opposed to 3.3 volts used in SDR SDRAM, and requires 184-pin DIMM modules
rather than 168-pin DIMM modules used by SDR SDRAM. Please note that
the DDR SDRAM does not support ECC (error correcting code) and registered
DIMM.
DDR Population Rules
Install at least one DIMM module on the slots. Each DIMM slot supports
up to a maximum size of 1GB. Users can install either single- or double-sided
modules to meet their own needs. Please note that each DIMM can work
respectively for single-channel DDR, but there are some rules while using
dual-channel DDR (Please refer to the suggested DDR population table on p.
2-8). Users may install memory modules of different type and density on
different-channel DDR DIMMs. However, the same type and density memory
modules are necessary while using dual-channel DDR, or instability may happen.
2-7
MS-6728 ATX Mainboard
Please refer to the following table for detailed dual-channel DDR. Other
combination not listed below will function as single-channel DDR.

MSI Reminds You...
Dual-channel DDR works ONLY in the 3 combinations listed in
the table above.
Installing DDR Modules
1. The DDR DIMM has only one notch on the center of module. The module
will only fit in the right orientation.
2. Insert the DIMM memory module vertically into the DIMM slot. Then
push it in until the golden finger on the memory module is deeply inserted
in the socket.
MSI Reminds You...
You can barely see the golden finger if the module is properly
inserted in the socket.
3. The plastic clip at each side of the DIMM slot will automatically close.

(clocks) increases the system performance the most while 3 (clocks)
provides the most stable performance.
RAS# Precharge
This item controls the number of cycles for Row Address Strobe
(RAS) to be allowed to precharge. If insufficient time is allowed for
the RAS to accumulate its charge before DRAM refresh, refreshing
may be incomplete and DRAM may fail to retain data. This item
applies only when synchronous DRAM is installed in the system.
Available settings: 2 clocks, 3 clocks, 4 clocks.
RAS# to CAS# Delay
When DRAM is refreshed, both rows and columns are addressed
separately. This setup item allows you to determine the timing of the
transition from RAS (row address strobe) to CAS (column address
strobe). The less the clock cycles, the faster the DRAM performance.
Setting options: 2 clocks, 3 clocks, 4 clocks, .
Precharge Delay
This setting controls the precharge delay, which determines the timing
delay for DRAM precharge. Settings: 5 clocks, 6 clocks, 7 clocks, 8
clocks, .
Burst Length
This setting allows you to set the size of Burst-Length for DRAM.
Bursting feature is a technique that DRAM itself predicts the address
of the next memory location to be accessed after the first address is
accessed. To use the feature, you need to define the burst length,
which is the actual length of burst plus the starting address and
allows internal address counter to properly generate the next memory
location. The bigger the size, the faster the DRAM performance.
Available settings: 4, 8.
AGP Aperture Size (MB)
This setting controls just how much system RAM can be allocated to AGP for
video purposes. The aperture is a portion of the PCI memory address range
dedicated to graphics memory address space. Host cycles that hit the aperture
range are forwarded to the AGP without any translation. The option allows the
selection of an aperture size of 4MB, 8MB, 16MB, 32MB, 64MB, 128MB, and
256 MB.

1. Even though MAT is easy to use, it doesn't mean there's no
risk at all. We recommend you to check if your memory is
able to bear MAT setting or not before deciding to always
use it. If your system will be unstable or reboot incidentally
after switching to Fast, please switch back to Normal.
Moreover, if you want to conduct FSB overclocking, you
should set MAT as Normal.

D.O.T. Range
(D.O.T) Dynamic Overclocking Technology is the automatic overclocking
function, included in the MSITM’s newly developed CoreCellTM Technology. It
is designed to detect the load balance of CPU while running programs, and to
adjust the best CPU frequency automatically. When the motherboard detects
CPU is running programs, it will speed up CPU automatically to make the
program run smoothly and faster. When the CPU is temporarily suspending or
staying in the low load balance, it will restore the default settings instead.
Usually the Dynamic Overclocking Technology will be powered only when
users' PC need to run huge amount of data like 3D games or the video process,
and the CPU frequency need to be boosted up to enhance the overall
performance. Setting options:
Disabled
Disable Dynamic Overclocking.
Private
1st level of overclocking.
Sergeant

Captain
3rd level of overclocking, also the default value of "Load

General
5th level of overclocking.
Commander 6th level of overclocking.
MSI Reminds You...
Even though the Dynamic Overclocking Technology is more
stable than manual overclocking, basically, it is still risky. We
suggest user to make sure that your CPU can afford to
overclocking regularly first. If you find the PC appears to be
unstable or reboot incidentally, it's better to disable the Dynamic Overclocking or to lower the level of overclocking options.
By the way, if you need to conduct overclocking manually, you
also need to disable the Dynamic OverClocking first.

The value plus a ratio (CPU: DDR) with parentheses means the
non-synchronous overclocking.
Spread Spectrum
When the motherboard’s clock generator pulses, the extreme values (spikes)
of the pulses creates 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, activate the Spread Spectrum 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. Options: Disabled,
Enabled.

best system performance but probably will cause a stability issue. The BIOS
Setup Defaults are the default values also set by the mainboard manufacturer
for stable performance of the mainboard.
When you select Load High Performance Defaults, a message as below appears:
Pressing ‘Enter’ loads the default BIOS values that enable the best system
performance but may lead to a stability issue.
MSI Reminds You...
The option is for power or overclocking users only. Use of high
performance defaults will tighten most timings to increase the
system performance. Therefore, a high-end system configuration
is a must, which means you need high-quality VGA adapter,
RAM and so on. We don’t recommend that users should apply
the high performance defaults in their regular systems.
Otherwise, the system may become unstable or even crash. If the
system crashes or hangs after enabling the feature, please CLEAR
CMOS DATA to resolve the problem. For more information, refer
to “Clear CMOS Jumper: JBAT1” in Chapter 2.
When you select Load BIOS Setup Defaults, a message as below appears:
Pressing ‘Enter’ loads the default values that are factory settings for stable
system performance.
