So I just got a new haswell laptop that came with one 1.35v 4gb stick of 1600mhz ram. I pretty much need to dual-channel for the integrated graphics, and I was just wondering what memory upgrades should be compatible. Could I just get a 1.35v 2x4 2133mhz pack? Or might there be other silly problems?

The ram is running 1600mhz 11-11-11 by default, and I've found the official replacement model and the same ones used. But I'm more curious if faster 2133mhz ram would work at the faster speeds in my system.
