Using 2x8 Gb in P9x79 WS would cause any problems?

[super sharp]

My MotherBoard is P9X79 WS(Workstation), I have one slot of 8GB and I'm planing to buy other 8GB, would it cause me any problems?

No, just keep in mind that you may have to reset the CMOS on the board after installing new memory for it to post and boot.
