What does this mean, The CPU control the memory the buss has to match CPU for it to work.
What is your CPU is it i5or i7 core.
For the i5 core the 1333 and 1066 work best.
And i7 the 1600 dose more Hyper tread per core on 1333 you can only use one memory slot regardless what size you use.
The other thing is memory can not be ganged for Hyper tread on i5.
