You shod be totally fine to max out the voltage in afterburner@1.087
but when i overclock the core clock the shader is going up automaticly

Core and Shader clocks are linked in Fermi architecture. That's just how it is. You should be able to hit anything between 700/1400 and 800/1600 easy with most GTX 470's. It would probably be a good idea to set up a custom fan profile after you do so so that the card's get a decent amount of cooling.

I've got my cards both at 1.087v @ 800 core, 1600 shader and 1950 memory.

Fan settings:

0-35C = 40% fan speed
50C = 50% fan speed
60C = 63% fan speed
70C = 75% fan speed
80C = 80% fan speed
90C = 90% fan speed
91C-100C = 100% fan speed

Folding 24/7 on these cards and gaming with these fan settings keeps the first one at about 77C and the second at 74C.

Good luck with the OCing!

Well when overclocking video cards you typically want to push the core/shader and memory speeds up while testing them for stability.

If you have a discriminating eye just use a benchmark like Unigine Heaven.

If you have green flashing, shapes you've probably pushed the core/shader too far for the current voltage. If you want to go further, increase the voltage. If you've maxed the voltage then you've reached the card's limits.

If you have white flashing dots you've reached the limits of the memory. If you want to go further, increase the voltage. If you've maxed the voltage then you've reached the card's limits.

As for your question on memory speed you might as well push the card as far as it'll go. So long as you have a good custom fan profile to keep heat in line there shouldn't be any real problems.
