• Make sure that the motherboard supports the memory. It is recommended that memory of the same capacity, brand, speed, and chips be used. (Go to GIGABYTE's website for the latest supported memory speeds and memory modules.) • Always turn off the computer and unplug the power cord from the power outlet before installing the memory to prevent hardware damage.
Due to CPU limitations, read the following guidelines before installing the memory in Dual Channel mode. Dual Channel mode cannot be enabled if only one DDR3 memory module is installed. When enabling Dual Channel mode with two memory modules, it is recommended that memory of the same capacity, brand, speed, and chips be used for optimum performance.
Line In Jack (Blue) The line in jack. Use this audio jack for line in devices such as an optical drive, walkman, etc. Line Out Jack (Green) The line out jack. Use this audio jack for a headphone or 2-channel speaker. This jack can be used to connect front speakers in a 4/5.1/7.1-channel audio configuration.
