Where you using overdrive? I've noticed if you do use it that it doesn't reduce the memory clocks when idling.
Disable overdrive and it will idle with gpu at 100 and mem at 300, enable it and it will raise the gpu to 300 minimum and memory at full speed.
Thats on a sapphire card - not sure they all do it so could just be a bios bug.
