You need to upgrade memory in a system but you don't have the motherboard documentation available. you open the case and notice that the board has four dimm slots; three slots are colored yellow and one slot is black. what type of dimm does the board likely use? how can you be sure?
The three yellow slots proably indicate triple channeling, which means the board uses DDR3 DIMMA. To know for sure, remove a DIMM and look for the position of the notch on the DIMM.
