0mh/s memload = 0%

Hello all. Im new here, may I know why my xfx rx 570 8gb card shows memload = 0% on amd-info details, eventhough I have the miner started? Tried with and without oc. Only shows 0mh/s all the time until rig restarted.

All my other cards shows and increase of memload as soon as the miner has started. Any helps is very much appreciated.

Thank you
