HD 6770M working @ 200Mhz memory

[wajed]

I opened GPU-Z and it shows this:-

GPU Clock: 725 Mhz Memory: 800 Mhz
Default Clock: 725Mhz Memory: 216 Mhz

When I run Cinebench R11.5 OpenGL test, GPU-Z (in the sensors tab) shows GPU Memory Clock 216 Mhz, Load approx 90%, approx 70 C.
My OpenGL score is 44.24 fps. So, is GPU-Z just showing wrong info, or is that a low score?
