[. . . ] 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. [. . . ] The memory module has only one notch on the center and will only fit in the right orientation. Insert the memory module vertically into the DIMM slot. Then push it in until the golden finger on the memory module is deeply inserted in the DIMM slot. The plastic clip at each side of the DIMM slot will automatically close when the memory module is properly seated. You can barely see the golden finger if the memory module is properly inserted in the DIMM slot. 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. Then push down the power supply firmly into the connector. 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. Each connector can connect to one Serial ATA device. Important Please do not fold the Serial ATA cable into 90-degree angle. Otherwise, data loss may occur during transmission. 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. [. . . ] This delay is required to guarantee that data in the write buffers can be written to the memory cells before precharge occurs. TRRD When the DRAM Timing Mode sets to [Manual], the field is adjustable. Specifies the active-to-active delay of different banks. TWTR When the DRAM Timing Mode is set to [Manual], the field is adjustable. [. . . ]
