The reason this is crucial is that too high an intensity can actually be disastrous with scrypt because it CAN run out of ram. High intensities -start writing over the same ram and it is highly dependent on the GPU, but they +start writing over the same ram and it is highly dependent on the GPU, but +they can start actually DECREASING your hashrate, or even worse, start producing garbage with HW errors skyrocketing.
