User manual MSI G41M-P33 COMBO

[. . . ] MS-7592 FCC-B Radio Frequency Interference Statement This equipment has been tested and found to comply with the limits for a class B digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. However, there is no guarantee that interference will occur in a particular installation. [. . . ] Manually check if the memory module has been locked in place by the DIMM slot clips at the sides. Volt Notch Important * In Dual-Channel mode, make sure that you install memory modules of the same type and density in different channel DIMM slots. * To enable successful system boot-up, always insert the memory modules into the DIMM1 first. 15 ATX 24-Pin Power Connector: JPWR1 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 power supply is inserted in the proper orientation and the pins are aligned. ATX 4-Pin Power Connector: JPWR2 This 4-Pin power connector is used to provide power to the CPU. Important Make sure that all the connectors are connected to proper ATX power supplies to ensure stable operation of the mainboard. iDE Connector: IDE1 This connector supports IDE hard disk drives , optical disk drives and other IDE devices. Important If you install two IDE devices on the same cable, you must configure the drives to cable select mode or separately to master / slave mode by setting jumpers. Refer to IDE device documentation supplied by the vendors for jumper setting instructions. Important Please do not fold the Serial ATA cable into 90-degree angle. Fan Power Connectors: CPUFAN1, SYSFAN1, SYSFAN2 The fan power connectors support system cooling fan with +12V. When connecting the wire to the connectors, always note that the red wire is the positive and should be connected to the +12V; the black wire is Ground and should be connected to GND. If the mainboard has a System Hardware Monitor chipset onboard, you must use a specially designed fan with speed sensor to take advantage of the CPU fan control. N 3 S/PDIF-Out Connector: JSP1 This connector is used to connect S/PDIF (Sony & Philips Digital Interconnect Format) interface for digital audio transmission. V 1 17 Front Panel Connectors: JFP1, JFP2 These connectors are for electrical connection to the front panel switches and LEDs. The JFP1 is compliant with Intel® Front Panel I/O Connectivity Design Guide. Ake r Front Panel Audio Connector: JAUD1 This connector allows you to connect the front panel audio and is compliant with Intel® Front Panel I/O Connectivity Design Guide. Front USB Connector: JUSB1, JUSB2 This connector, compliant with Intel® I/O Connectivity Design Guide, is ideal for connecting high-speed USB interface peripherals such as USB HDD, digital cameras, MP3 players, printers, modems and the like. Please refer to the TPM security platform manual for more details and usages. PCI Interrupt Request Routing The IRQ, acronym of interrupt request line and pronounced I-R-Q, are hardware lines over which devices can send interrupt signals to the microprocessor. The PCI IRQ pins are typically connected to the PCI bus pins as follows: Order Slot PCI 1 1 INT A# 2 INT B# 3 INT C# 4 INT D# 21 BIOS Setup Power on the computer and the system will start POST (Power On Self Test) process. [. . . ] This setting determines the time RFC takes to read from and write to a memory cell. TWR When the DRAM Timing Mode is set to [Manual], the field is adjustable. It specifies the amount of delay (in clock cycles) that must elapse after the completion of a valid write operation, before an active bank can be precharged. This delay is required to guarantee that data in the write buffers can be written to the memory cells before precharge occurs. [. . . ]
