do you need more ram though? seems like a slight hassle where none is needed, and honestly you could very cheaply get a second 8GB dimm online and get some easy dual channel operation, after which you would want to ditch the 2GB dimm anyway.
I believe OP was pointing out that the ram is indeed running at 1333, as opposed to 1600.
I'm not sure.. earlier he said that..
bit i canot use my 8 gb ram at 1600mhz because of the limitation of my cpu
