Solution
If your board has 4 DIMM slots and not 2, yes. But for best results you always want to populate dual channel systems like yours with MATCHED pairs of memory. Dual Channel is very picky about the speed, timings, voltages, etc being identical. If you have 2 sticks in use now and add a 3rd stick, you may lose dual channel memory speed. The RAM may revert to single channel mode.
