Corsair Dominator 4GB(2x2GB) DDR3 1600MHZ

If this is what you bid on:
http://www.newegg.com/Product/Product.aspx?Item=N82E168...
then I would say no if you are buying from an individual. It all depends on what return priviledges, if any, he would give you.

it is used one, but i don't mind if the ram don't have any problem.

The ram is another one, model: TW3X4G1600C9D. Used to sell at $130 and above.
It has been deactivated.

I don't know why it is deactivated, but i can't find any current price through internet.
Should be around 80 i think.

Any idea about the performance/price?
