So as listed i have 8 gb of DDR3 G.Skill RipJawsX clocked at 2133MHz. Basically the ones in here; http://www.mindfactory.de/product_i...awsX-DDR3-2133-DIMM-CL11-Dual-Kit_739280.html They are really cheap considering their price about a month or two ago when they were selling as high as 80 euros. I would like to buy another 2 sticks and have a total of 4 sticks and 16 gb of RAM. (I know you guys could've done the math on your own, i was just trying to do it for you just in case you were lazy.) Now, the thing is they have a latency of CL11, while these http://www.mindfactory.de/product_i...JawsX-DDR3-2133-DIMM-CL9-Dual-Kit_748020.html with CL9 are going for the same price. I don't really know if i can achieve the same timing with the ones i have to match the profile of those. They come in Red too, so the colors are an issue. Btw the voltage of mine 1.6 while it is 1.65v of the cl9 ones. So which should i pick? and no i don't plan to spend twice the amount just to get 2x8gb sticks so that in the future i can have 32gb of RAM if i plan to upgrade.
