Newegg has a 15% off discount code that expires today. I recommend (2) 4 gb sticks of 1600 if your board and budget can handle it. I use plain gskill ripjaws 1600. It runs at 9-9-9-24, which looks slow on paper, but performs well when the cpu is overclocked. I won't pay extra for ram with lower timings, but some folks will. The lower numbers certainly help, but they come at a price.
actually kingmax has 7 7 7 sticks that are cheaper than corsair on 9 9 9
why is that?
