I am using a CUDA enabled graphics card to crunch numbers. What role does the SHADER CLOCK play in the speed of crunch? Will It help?

CUDA is crunched on the shaders.

The core clock runs some functions on the multiprocessor level, like the instruction decoder, and the shader clock runs the individual processors. The shader clock is the fastest of the two, and this sets the speed of arithmetic operations by the processor.

So if you overclock them, calculations should theoretically go faster. It will generate more heat though and may also create more instability.
