I am about upgrade from G41 platform to X58. I currently have 2 sticks of GSkill DDR3 1333 memory. My next motherboard will support 6 sticks of DDR3. I would like to buy another 8 GB pair of the same GSkill memory that I have, add one stick to my current pair for my next computer and put the remaining stick in another computer. What are the odds of getting that to work? Do I have to buy a matched set of 3 sticks for my X58? I plan to run at stock speed without overclocking. Is it really necessary to get matched sets if I don't plan to overclock (just same type of memory, brand, model)? I ultimately would like to upgrade to 24 GB, but only need 8 or 12 GB for now. Same question, if I buy a 12 GB kit now, could I add in another 12 GB later (same kit) once prices fall?
