Good morning, I currently have Corsair Vengeance 8 GB : 2 x 4 GB - DIMM 240-pin - DDR3 CL8 ( 8-8-8-24 ) 1600Mhz. In certain applications I'm running out of memory, especially for video editing. I would like to add 2x4gb but needless to say this memory is no longer available at the moment. Is there an alternative I can add ? My Mb is a Gigabyte Z68X-UD7-B3 model and I'm running my Intel Core i7 2600K 3.4Ghz at 4.1 Ghz.
