I did not notice until I was starting to put this together that the mobo documentation says it supports DDR3 1333/1066 memory; the memory I purchased is DDR3 1600.
I believe this memory will work but wanted to ask the community if there may be issues.
Should I return the memory and buy DDR3 1333?
The memory you got will work fine in the motherboard. It can work perfectly as 1333 DRAM or you can overclock the motherboard settings to run it as 1600.
It's not particularly great RAM, slow for 1600 speed with a CL=9, but there's certainly nothing wrong with it. Any 1600 RAM will work as 1333.
If you bought the MB and RAM as a combo, you could complain that it isn't fully supported by the board to avoid re-stocking fee. It is supported however, since the board advertises speeds over 1333 with OC.
