Memory Upgrade - Add or Replace?

My soon to be son-in-law wants a PC upgrade for Christmas. The PC is a couple years old so I was planning on increasing his RAM.

Motherboard: AS Rock x99M Extreme 4 
Current Memory: Ballistix 2x8 GB 

Labels on DIMM modules:
BLS8G4D240FSA.M16FADM
BG112SV.28
2400 MHz 16-16-16-39 1.2v

Searching for that part number I find a lot of FSB as opposed to FSA memory. Any idea what the difference is?

Will putting in two more sticks of this memory be OK or should I just buy a set of 4 and have him toss the other two? For a couple year old PC it doesn't seem worth spending the extra money if buying two sticks will work.

Re: Memory Upgrade - Add or Replace?

@Crash55 Thanks for contacting us. I pulled up your system and the part numbers and it appears the only difference between FSA and FSB parts is that FSA parts were just an old part number we have moved on from. The two are completely compatible with each other. I would recommend just purchasing two more parts for that system. Please let me know if you have any other questions or concerns.
