The system BIOS monitors CPU cooling fan speeds and if the fan isn’t connected to this header, you may get an error at bootup.Įight-pin ATX12V (CPU power) connector: Back when the Pentium 4 processor first shipped, Intel realized that high-performance CPUs needed their own source of clean, dedicated power beyond what the standard 24-pin power connector could deliver. The system supports dual-channel memory, meaning that the system is populated with paired memory modules, which are mounted in sockets of the same color.ĬPU fan header: This connector is specifically designed to link to the CPU cooling fan. The P67 chipset used in this board maxes out at DDR3-1600, but to achieve that level of speed you’d have to overclock the chipset–officially the P67 supports only DDR3-1333. Intel D67BG motherboard: a modern Intel design.ĭDR3 memory sockets: Current-generation PC systems use DDR3 memory, but in many instances they support different operating speeds. Now let’s examine a more recent motherboard: an Intel D67BG, based on Intel’s P67 chipset and supporting LGA 1155 CPUs (like the Sandy Bridge-based Core i7-2600K). And if you do find yourself needing a floppy drive, you can always pick up an external, USB-connected drive. But unless you have a pile of old floppies, you won’t need a floppy drive. Floppy disk connector: The venerable 3.5-inch floppy disk drive survived for nearly two decades–an eternity in the tech universe.
