These are some of the best choices. The reason that I did not recommended the Corsair Vengance at the first place is because it's heatsinks are quite big which can cause clearance issues with some CPU Coolers, which is why i recommended the G.Skill Sniper. It is an awesome small RAM which is a very good performer.
I hope this helps. Is there anything else I can do for you? I would be happy to help.
