When you buy ram look at the motherboard qal list for tested ram first. Then use parts picker to look to see if there any good ram on sale or combo. Most new mb will run with one dimm but most now have duel memory controllers so to get the best speed most new mb look for two matched dimms. With newer ram stick be carefull of the heat spreaders. Lot of them like the one you picked are tall and sometime don't fit under some air coolers. Look at low profile ram.
