Please Note: Motherboards are part number specific. You must search by the exact part number of the motherboard you are replacing. The manufacturer part number of the original motherboard has to be an exact match to one you are buying or listed under the list of compatible part numbers, otherwise it may be different and may not work. Buying a matching part number is required in order to avoid returns, delays and lost shipping fees. You can NOT go by the model or serial number of the system alone! We obtain cross reference and compatibility information from the manufacturer (as well as various other sources) and while we do this to the best of our ability, we do not guarantee its accuracy. If you are unsure, please check with your system manufacturer. Please order based on the part number only!
