This does however illustrate that there is no fixed ratio of core:shaders as you are suggesting. Instead I expect it to be more like a divider ratio that you also see in FSB/Memory frequencies, where the memory frequency will automatically adjust to a more favourable setting near your manual input, in relation to the divider complexity.
I have never witnessed it going to something other than 1:2 when you look at the exact clocks on Hardware Monitor.
Thinking about it further, the stock clocks on my GTX 260 are 590/1296 which is not a 1:2 ratio. So there we can see that it may not always be 1:2. However, as I said before, my experience and what I have seen from many other people says that maintaining a 1:2 ratio of Core/Shader provides the best folding experience.
*EDIT* I think we are comparing apples to grapples here. I just realized I am talking about the GT200 series, and you guys are on the G92 chips. There must be a difference in architecture for these chips that requires different core/shader settings.Edited by Greg121986 - 2/25/09 at 9:53am
