I want to upgrade from 1 stick of RAM to 2 stick of RAM, but here's the catch...I bought the older version of kingston's hyperX:
http://www.amazon.com/gp/product/B007TTEHUY?psc=1&redirect=true&ref_=oh_aui_detailpage_o00_s02

and now that version isn't being produced anymore...My question is, if I buy 1 stick of the newer version of the hyperX: http://www.amazon.com/Kingston-HyperX-FURY-1600MHz-DDR3/dp/B00J8E92M6/ref=dp_ob_title_ce, can I still use it alongside the older version? Or should I just buy a new set, 2x4?

Thanks in advance!!
