Memory
The mainboard provides 4 slots for 184-pin DDR SDRAM DIMM (Double In-Line Memory
Module) modules and supports the memory size up to 4GB. You can install DDR266/
333/400 modules on the DDR DIMM slots (DDR 1~4).
For the updated supporting memory modules, please visit http://www.msi.com.tw/ program/products/mainboard/mbd/pro_mbd_trp_list.php.
DIMM1~4
(from bottom to top)
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. High memory bandwidth makes DDR an ideal solution for high performance PC, workstations and servers.
DIMM Module Combination
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 DIM M can work respectively for singlechannel DDR, but there are some rules while using dual-channel DDR (Please refer to the suggested DDR population table below) .
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. Please refer to the following table for detailed dual-channel
DDR. Other combination not listed below will function as single-channel DDR.

- Please select the identical memory modules to install on the dual channel, and DO NOT install three memory modules on three
DIMMs, or it may cause some failure.
- Always insert the memory modules into the GREEN slots first, and it is strongly recommended not to insert the memory modules into the PURPLE slots while the GREEN slots are left empty.
- This mainboard DO NOT support the memory module installed with more than 18 pieces of IC (integrated circuit).

(power-off) states, and the power code is plugged while installing modules. Due to several pins are very sensitive to ESD, so this kind of memory-replacement actions might cause system chipset unable to boot. Please follow the following solution to avoid this situation.
Unplug the AC power cable (shown in figure 1) or unplug the ATX1 & JPW 1 power connectors (shown in figure 2 & figure 3) before the 1st installation or during system upgrade procedure.
Figure 1:
Unplug the AC power cable

Dynamic Overclocking
Dynamic Overclocking Technology is the automatic overclocking function, included in the MSI TM ’ s newly developed CoreCell TM Technology. It is designed to detect the load balance of CPU while running programs, and to adjust the best CPU frequency automatically. W hen the motherboard detects CPU is running programs, it will speed up CPU automatically to make the program run smoothly and faster. W hen 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:

[Commander] 6th level of overclocking, increasing the CPU frequency by 11%.
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 D.O.T Ranger first.

RAID Configuration
Basic Configuration Instructions
The following are the basic steps for configuring NVRAID:
Non-Bootable RAID Array
1. Choose the hard disks that are to be RAID enabled in the system BIOS.
2. Specify the RAID level, either Mirroring (RAID 1), Striping (RAID 0), Striping and
Mirroring (RAID 0+1), or Spanning (JBOD) and create the desired RAID array.
3. Enter the W indows OS, run the W indows nForce Setup application and install the
RAID software. (Check p.5-9 for details.)
4. Initialize the NVRAID Array Disks.
Bootable RAID Array
1. Choose the hard disks that are to be RAID enabled in the system BIOS.
2. Specify the RAID level, either Mirroring (RAID 1), Striping (RAID 0), Striping and
Mirroring (RAID 0+1), or Spanning (JBOD) and create the desired RAID array.
3. Boot from the W indows CD, use the floppy disk that has the RAID driver to copy
and install the nForce RAID software. (Check p.5-9 for details.)
4. Initialize the NVRAID Array Disks.
Setting Up the NVRAID BIOS
Be sure to enable the IDE RAID or SATA RAID items in RAID Config of Integrated
Peripherals in BIOS before configuring the NVRAID BIOS. After that press F10 to save the configuration and exit. The PC will reboot right away. Then enter the RAID
BIOS Setup by pressing F10 when prompted, and follow the procedures described below to set up the NVRAID BIOS.
NVRAID BIOS setup lets you choose the RAID array type and which hard drives you want to make part of the array.
Entering the RAID BIOS Setup
1. After rebooting your PC, wait until you see the RAID software prompting you to press F10 . The RAID prompt appears as part of the system POST and boot process prior to loading the OS.
2. Press F10 , and the NVIDIA RAID Utility
--- Define a New Array window will appear.
The default RAID Mode is set to Mirroring and Striping Block is set to

M S-7125 ATX M ainboard
Understanding the “ Define a New Array ” Window
Use the Define a New Array window to
• Select the RAID Mode
•
Set up the Striping Block
• Specify which disks to use for the RAID Array
Depending on the platform used, the system can have one or more channels. In a typical system there is usually one controller and multiple channels, and each channel has a slave and a master.
The channel/controller/master/slave status of each hard disk is given in the Loc
(location) columns of the Free Disks and Array Disks lists.
In the example above, 1.0.M means the hard drive is attached to Channel 1, Controller
0, and the drive is set to Master. The following is a list of all possible combinations:
Parallel ATA
0.0.M
0.0.S
Channel 0, controller 0, Master
Channel 0, controller 0, Slave
0.1.M
0.1.S
Channel 0, controller 1, Master
Channel 0, controller 1, Slave
Serial ATA

Channel 1, controller 0, Master
Channel 1, controller 1, Master
Channel 2, controller 0, Master
Channel 2, controller 1, Master
MSI Reminds You...
There is no such thing as Slave drive in Serial ATA. All drives are considered to be Master since there is a one to one connection between the drive and the controller.

Setting Up a Spare RAID Disk
You can designate a hard drive to be used as a spare drive for a RAID 1 or RAID 0+1 array2. The spare drive can take over for a failed disk. NVRAID supports two types of spare drives:
• Free Disk
A free disk is a disk that is not part of any RAID array, but can be used by any available RAID 1 or RAID 0+1 array that requires a particular disk when one of its disks crashes or becomes unusable. The process is automatic and doesn
’ t require any user interaction.
For example, if you have a system with four hard disks where one disk is used to boot the OS, two hard drives are set up in a mirrored array, and a fourth hard disk is set up as a free disk, then if one of the mirrored array drives fails, the free disk will be automatically assigned to the mirrored array to be used instead of the failed disk.
• Dedicated Disk
A dedicated free disk is a disk that is assigned to a RAID 1 or RAID 0+1 array and that disk is used by that array only when needed, for example during a system crash where a RAID mirrored drive is broken. The dedicated disk can be used only by the array that it is assigned to and not by any other array, unlike a free disk which can be used by any available RAID 1 or RAID 0+1 array.
Assigning a Free Disk
To mark a disk as free, or not a part of any array,
1.
Enter the system BIOS setup and make sure that the drive that you want to mark as free is RAID enabled.
2.
Enter the RAID BIOS and make sure that the drive is not part of any array (if one exists).
3.
Boot into W indows and run the NVRAIDMAN program. The drive appears under the
Free Disk section. The figure below shows an example of the NVRAIDMAN display if you have a mirror array and one free disk.
4-14
nVIDIA RAID Introduction
Assigning a Dedicated Disk
To mark a disk as dedicated, or reserve it for use by a specific array,
Step 1: Mark the Disk as a Free Disk
1.
Enter the system BIOS setup and make sure that the drive that you want to mark as free is RAID enabled.
2.
Enter the RAID BIOS and make sure that the drive is not part of any array (if one exists).
3.
Boot into W indows and run the NVRAIDMAN program. The drive appears under the
Free Disk section.
Step 2: Dedicate the Free Disk to an Array
W hile running NVRAIDMAN, dedicate the free disk to an array using one of the following two methods:
• Method 1: Select a free disk and then assign it to an array.
• Method 2: Select an array and then assign a free disk to it.
Both methods are equally simple ways of accomplishing the same task.
M ethod 1: Select a free disk and then assign it to an array.
1. Right click one of the available disks under the Free Disk section. The pop-up menu
appears.
2. Select Designate Spare from the menu to launch the Spare Disk Allocation Wizard.

Rebuilding a RAID Mirrored Array
Rebuilding is the process of recovering data from one hard drive to another. All data is copied from one hard drive to another and then the data is synchronized between the two hard drives. This only applies to RAID 1 array as well as a RAID 0+1 array.
Rebuilding Instructions
After creating a mirrored array, you can rebuild the array using the following steps:
1.
Go to Windows and run the NVRAID Management utility. The figure below shows an example of a system with one mirrored array.
2 . Right-click on Mirroring. The popup menu appears.

M ore About Rebuilding Arrays
• Rebuilding Occurs in the Background
The rebuilding process is very slow (it can take up to a day) and occurs in the background so as not to affect the performance of the system.
•
Rebuilding Applies Only to RAID 1 or RAID 0+1 Arrays
Rebuilding an array works only when using RAID1 and/or RAID 0+1. Rebuilding does not apply to RAID 0 and JBOD arrays.
• You Can Use Any Available Free Disk
You can rebuild a mirrored array using any available Free Disk or Dedicated Disk.
For example, the figure below shows a mirrored array using 34.48 GB HD while having two Free Disks each 55.90 GB large.
To use one of these available free disks to rebuild your array, except when prompted to select a disk, choose one of the two available free disks.
