Help for choosing memory

Gskill is a good brand and it has good prices.

Here you have the list of compatible memory modules.

I would suggest you to choose the cheaper ones.

If you can't get Gskill, then look for Team or Kingston. Corsair is the best but they are very expensive.

Thanks guys.
Sorry, because of my bad English.I think, there isn't the Ripjaws series of GSKILL in my country,i'll pick up an OCZ one.

Do you think it's need to choose one with CL7?

Corsair or OCZ fine
