On my Notebook I had a strip of origin 4GB installed, I had frequently lags microphones partly in the Red Dragon Wargame games. Having lowered the quality of the games thinking that the cause was too low capacitée my graphics card, nothing has changed, so I realized that was wrong ram (not my i7 processor that is) I ordered this ram, I just do lag and games is more fluid now, I take off a star for the price too expensive compared to the cost of manufacture.
