I have installed this G.SKILL Sniper Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1866 (PC3 14900) Desktop Memory Model F3-14900CL9D-8GBSR - Newegg.com on an Asus Z87-A motherboard/ i5 4670k processor and was wondering, if I could order another identical pair to increase to a total of 16GB. Should the tolerances between the two different pairs be close enough to work together without any conflicts? if so I'll order another pair now. Thanks!
