Have a mid-2010 macbook pro that I want to keep for a bit longer. Use a lot of memory intensive programs such as aperture and multiple tabs of chrome. Currently have 8GB of ram and want to move up to 16GB. I know my machine supports 1067MHz ram but can I also use 1333MHz modules? And what's up with these: http://www.ebay.ca/itm/16GB-DDR3-PC...?pt=US_Memory_RAM_&hash=item5647821f22&_uhb=1 Does anyone know if these rams are trustworthy and if there is any brand behind them? Also, can I use a 4K display via displayport? How about an LG 34UM95?
