hello, i just got this 2x8Gb set (G.Skill Sniper Series: F3-1866C9D-16GSR) and tried on my ASUS P8H77-V LE with an intel core i3 CPU and they just don't work in dual channel!! the PC won't start unless i took 1 off and then it works, what can i do? i know the BIOS lets you set the RAM speed, but...
