Need advice on buying a ram!

[vigneshkrishnan758]

Which ram should I buy for my Sony laptop sve15127cnb. I'm a gamer so I need a effective ram.
I have selected corsair vengeance ddr3 4gb laptop ram.
Can anyone suggest me anything better or I should go with this?

Your laptop has HD 7650M...

So technically, you are good to go with any low latency RAM out there, but they won't affect gaming performance much, actually I doubt if there will be any increase at all, except during loads. Corsair Vengeance is fine.
Another note, if you are thinking to supplement your stock RAM, then I would recommend buying two memory modules of same type for running them in dual channel mode, flawlessly.
