4870 core clock readings in GPU-Z?

Hi

I have my 1gb 4870 lightly OC'd with GPU at 810Mhz and Memory at 1025Mhz, but current values in CCC show the GPU at 500Mhz though above the overdrive slider shows 810Mhz?

GPU-Z also shows core clock at 500Mhz? (Under sensors 500Mhz, first page shows settings above default at 810Mhz?))

Does the Sapphire 4870 underclock when idle or have some sort of power saving feature?

They're your 2D Clock settings, so basically when you're not in a 3D application that requires rendering, the Graphics card will underclock itself, so save on power consumption. As soon as you go into a Game, clocks will jump up to the set 810MHz and 1025MHz.
