I have pegatron ipmsb-h61 motherboard and on the internet it says it supports ddr3 ram 1333mhz . I was thinking to upgrade my ram right now . Wanted to ask if i can install 1600 or 1866 or 2166 mhz of ram ( even if it downgrades the ram to 1333mhz then np because i m soon gonna upgrade my motherboard to a better one ) and also , the price of 1333 mhz ram and 1866 mhz ram will be the same for me . Thanks for answering
