RAM G.Skill vs Corsair Vengeance

[SIDDHARTH1101]

Hello

I am building a pc with 4gb ram

can anyone tell me why are people recommending me to buy 2 2gb ram sticks rather than a single 4gb stick

Because the RAM can run in the dual channel mode, then it will have better performances. http://www.gamersnexus.net/guides/1349-ram-how-dual-channel-works-vs-single-channel#!
