only gpu clock counts towards hashing power. memory clock is irrelevant.
you can underclock your memory to save some degrees temparature that you may better spend on some gpu clock OC

That's weird, I tried lowering my memory clock to 900 (minimum) and the performance lowered 10-20 mh / sec. As soon as I put them back up, they returned to what they previously were.
