Using the ATI overdrive in CCC is fine to a point. When that starts to fail, that is when you need extra volts which may or not help.
GpuTool - which I linked too (not CCC) - is the next step. This will let you test the capabilities with extra volts without applying them permanently.
im noticing a diffrence between my 8800GT that the proccesser is better by like 18000 in vantage but the 5890 is at like 7000 but its graphics is like 2-3 times better on its rating is that the difference between ATI and Nvidia?
That's because physx calculations are taken into account when running vantage and a nvidia card. Forget nvida card points. They are a different kettle of fish. it's the GPU score that counts. -as a reference.
okay i did fur tests with 900 core clock,1100 memory clock and this thing isnt going above 60C its normal clocks are 880 and 975 should i push further or this thing will play anything i throw at it?
Are you using GPU-Z to monitor temps? Core temp is one thing, mem is another and the VRM is another consideration. I'll explain the difference when I'm more lucid. In the interim, NO temps should go above 90c.
I'd concentrate on the core clock speed and leave the memory where it is for now. Ati overdrive will ramp up clock speeds on the default voltage. When hitting that wall, that's when bumping voltages comes into play.
As I said, lower clocked models are sold because essentially they are 'weaker' components. Raising voltages increases heat and as long as you the temps are within the parameters, this defines how far you should push it.
basically the end result equates to the difference of sustained minimum frame rate vs maximum framerate. max min is is better.
There is more i can add, but it's xmas day and I'm not all there atm..........
i could tell you to try this or try that - but flapping your card is something I'm trying to avoid with my advice. I'm taking the softly, softly approach. If you **** your card, it's not because of bad advice. It would be because you ignored it. Just remember, benchmark performance is one thing - game performance is another entirely.
