How memory clock relates to engine clock?

Hi, i'm not really into overclocking but have recently built a 2600K rig with a 6950. Overclocking the CPU was fine as I just used the Asus o/c utility which sets it to 4.4.

Not sure on the GPU though? If you look at the screen from the supplied SmartDoctor app below, i've raised it from 810 MHz to 833 MHz and it seems happy with that and my 3D Mark 11 score went from 5128 to 5237 so its obviously done somthing good.

Memory clock though, dont know what to do? I raised it 'some' from 5000 to 5044 but does it need to be in line with, or some multiplier of the engine speed?



Also, anyone know what vague numbers I can safely aim for?

Ta.

Thanks folks, wasn't sure whether they needed doing together but sounds like thats not the case so i'll have a play with the core clock speed to see what i can get. Looking at the numbers above, seems I can push it a fair way yet.
