E-2-6 Hardware Setup 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 left to right) 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 DIMM 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. E-2-7 MS-7125 M-ATX Mainboard DIMM Module Combination Install at least one DIMM module on the slots. You can install either single- or doublesided modules in any order to meet your own needs. Memory modules can be installed in any combination as follows: Slot DDR 1 (Bank 0 & 1) DDR 2 (Bank 2 & 3) Memory Module Total Memory S/D 64MB~1GB S/D 64MB~1GB Maximum System Memory Supported S: Single Side 64MB~2GB D: Double Side Installing DDR Modules

The DDR DIMM has only one notch on the center of module. The module will only fit in the right orientation. 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. The plastic clip at each side of the DIMM slot will automatically close. Volt Notch MSI Reminds You... You can barely see the golden finger if the module is properly inserted in the socket. E-2-8 Hardware Setup Power Supply The mainboard supports ATX power supply for the power system. Before inserting the power supply connector, always make sure that all components are installed properly to ensure that no damage will be caused.

E-3-5 MS-7125 M-ATX Mainboard Cell Menu The items in Cell Menu includes some important settings of CPU, AGP, DRAM and overclocking functions. MSI Reminds You... Change these settings only if you are familiar with the chipset. Current CPU / DDR Clock These two items show the current clocks of CPU & DDR. Read-only. High Performance Mode This field allows you to select the DDR timing setting. Setting options: [Manual], [Optimized]. Aggressive timing This item allows you to enable or disable the memory clock. When [Enabled] is selected, the timing delay of memory will be shorten to increase the performance. Setting options: [Enabled], [Disabled]. E-3-6 BIOS Setup Dynamic Overclocking 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] [Private] [Sergeant] [Captain] [Colonel] [General] [Commander] Disable Dynamic Overclocking function. 1st level of overclocking, increasing the CPU frequency by 1%. 2nd level of overclocking, increasing the CPU frequency by 3%. 3rd level of overclocking, also the default value of "Load High Performance Defaults", increasing the CPU frequency by 5%. 4th level of overclocking, increasing the CPU frequency by 7%. 5th level of overclocking, increasing the CPU frequency by 9%. 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. Adjust CPU FSB Frequency This item allows you to select the CPU Front Side Bus clock frequency (in MHz). Select the number between [200]~[400] for needed frequency. HT Frequency This setting specifies the maximum operating frequency of the link’s transmitter clock. Setting options: [1x], [1.5x], [2x], [2.5x], [3x], [4x], [5x]. HT Width This field allows you to set the HT Width between CPU & Chip.↑ mark means Chip to CPU HT Width. And ↓ mark means CPU to Chip HT Width. Setting options: [ ↓ 8 ↑ 8], [ ↓ 16 ↑ 8], [↓ 8 ↑16], [ ↓16 ↑16]. CPU Spread Spectrum This setting is used to enable or disable the CPU Spread Spectrum feature. When overclocking the CPU, always set it to [Disabled]. Setting options: [Center Spread], [Disabled]. E-3-7 MS-7125 M-ATX Mainboard SATA Spread Spectrum This setting is used to enable or disable the SATA Spread Spectrum feature. Setting options: [Disabled], [Down Spread]. PCIE Spread Spectrum This setting is used to enable or disable the CPU Spread Spectrum feature. When overclocking the CPU, always set it to [Disabled]. Setting options: [Disabled], [Down Spread]. PCIE Clock The system board designer selects whether the PCIE clock is tightly synchronized with the CPU clock or is asynchronous. Setting options: [100MHz]~[145MHz]. SSE/ SSE2 Instructions This setting disables/enables the SSE/SSE2 Instructions. The Streaming SIMD Extensions (SSE) were introduced in the Pentium III processor. The SSE extensions consist of a new set of instructions and a new set of registers. These instructions and registers are designed to allow Single-Instruction Multiple-Data (SIMD) computations to be made on single-precision floating-point numbers. The Streaming SIMD Extensions 2 (SSE2) were introduced in the Pentium 4 and Intel Xeon processors. They consist of a new set of instructions that operate on the XXM and MXCSR registers and perform SIMD operations on double-precision floating-point values and on integer values.Several of these new SSE/SSE2 instructions also operate in the MMX registers. Setting options: [Enabled], [Disabled]. Cool’n’Quiet control This feature is especially designed for AMD Athlon processor, which provides a CPU temperature detecting function to prevent your CPU’s from overheating due to the heavy working loading. Setting options: [Disabled], [Enabled]. E-3-8 BIOS Setup Adjust CPU Ratio This item lets you adjust the CPU ratio. Setting to [Startup] enables the CPU running at the fastest speed which is detected by system. Setting options are: [Startup], [x4]~ [x12]. Adjust CPU VID This item lets you adjust the CPU VID. Setting to [Startup] enables the CPU running at the default VID which is detected by system. Setting options are: [Startup], [0.825V], [0. 850V],[0.875V],~, [1.550V]. CPU Voltage This feature allows you to trim the voltage of CPU. Setting options are: [By CPU VID], [Over VID 3.3%], [Over VID 5.0%],[Over VID 8.3%]. Memory Voltage Adjusting the DDR voltage can increase the DDR speed. Any changes made to this setting may cause a stability issue, so changing the DDR voltage for long-term purpose is NOT recommended. Setting options are: [Auto], [2.50V]~[2.85V]. NF4 Voltage NV4 voltage is adjustable in the field. Setting options are: [1.50V]~[1.85V]. MSI Reminds You... The settings shown in different color in CPU Voltage, Memory Voltage and NF4 Voltage help to verify if your setting is proper for your system. Gray: Default setting. Yellow: High performance setting. Red: Not recommended setting and the system may be unstable. Changing CPU VID, CPU Voltage, Memory Voltage and NF4 Voltage may result in the instability of the system; therefore, it is NOT recommended to change the default setting for long-term usage.
