Ambient temperatures of your room?
Temperatures of the card at load?
Just because another card will clock that doesnt mean yours will.
What kind of cooler does it have?

You need RAM chip coolers.

Not every graphics card overclocks the same. Unfortunately, some doesn't OC as well as others and that seems to be your case.

If I were you I'd try to find out the highest OC I can go without getting a black screen whilst playing or when doing benchmarks.

I had that card well, actually a his iceq 5670 but thats besides the point and I was getting mine to 1000 core. In all honesty, I advise you worry less about ram speeds and try to go higher on the core. I am not sure about your card but mine could be voltage controled with rbe and if you can up the volts go higher on your core and be happy because that will make a bigger difrence.
