User manual MSI MS-7091 VERSION 1.X

[. . . ] BIOS The mainboard BIOS provides "Plug & Play" BIOS which detects the peripheral devices and expansion cards of the board automatically. The mainboard provides a Desktop Management Interface (DMI) function which records your mainboard specifications.

Hardware Setup Hardware Setup This chapter tells you how to install the CPU, memory modules, and expansion cards, as well as how to setup the jumpers on the mainboard. [. . . ] Therefore we suggest you do not plug/unplug the CPU too often. 2-6 Hardware Setup Memory The mainboard provides 4 slots for 184-pin DDR SDRAM DIMM (Double InLine Memory Module) modules and supports the memory size up to 4GB. You can install DDR400/DDR333 modules on the DDR DIMM slots (DIMM 1~4). DDR DIMM Slots (DIMM 1~4) Introduction to DDR SDRAM DDR (Double Data Rate) SDRAM is similar to conventional SDRAM, but doubles the rate by transferring data twice per cycle. 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. 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-7091 M-ATX Mainboard Please refer to the following table for detailed dual-channel DDR. Other combination not listed below will function as single-channel DDR. DIMM1 (Ch A) 128MB~1GB 128MB~1GB DIMM2 (Ch A) 128MB~1GB 128MB~1GB 128MB~1GB DIMM3 (Ch B) 128MB~1GB DIMM4 (Ch B) 128MB~1GB 128MB~1GB System Density 256MB~2GB 256MB~2GB 512MB~4GB MSI Reminds You. . . Dual-channel DDR works ONLY in the 3 combinations listed in the table above. Installing DDR Modules 1. 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 serted in the socket. in- 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. ATX 24-Pin Power Connector: ATX1 This connector allows you to connect an ATX 24-pin power supply. To connect the ATX 24-pin power supply, make sure the plug of the pin 13 power supply is inserted in the proper orientation and the pins are aligned. If you'd like to use the 20-pin ATX power supply, please plug your power supply along with pin 1 & pin 13 (refer to the image at the right hand). There is also a foolproof design on pin 11, 12, 23 & 24 to avoid wrong installation. pin 12 Pin Definition 13 1 PIN 1 2 3 4 5 6 7 8 9 10 1 1 12 SIGNAL +3. 3V +3. 3V GND +5V GND +5V GND PWR OK 5VSB +12V +12V NC PIN 13 14 15 16 17 18 19 20 21 22 23 24 SIGNAL +3. 3V -12V GND PS-ON# GND GND GND Res +5V +5V +5V GND ATX1 24 12 ATX 12V Power Connector: JPW1 This 12V power connector is used to provide power to the CPU.

[. . . ] PCI Express architecture provides a high performance I/O infrastructure for Desktop Platforms with transfer rates starting at 2. 5 Giga transfers per second over a PCI Express x1 lane for Gigabit Ethernet, TV Tuners, 1394 controllers, and general purpose I/O. Also, desktop platforms with PCI Express Architecture will be designed to deliver highest performance in video, graphics, multimedia and other sophisticated applications. Moreover, PCI Express architecture provides a high performance graphics infrastructure for Desktop Platforms doubling the capability of existing AGP8x designs with transfer rates of 4. 0 GB/s over a PCI Express x16 lane for graphics controllers. When adding or removing expansion cards, make sure that you unplug the power supply first. [. . . ]
