The thing about Perlin noise is that at frequency=1, there is roughly 1 feature per unit. At frequency=3, in your case, you have roughly 3 features per unit. However, you are sampling an area 64x48 units in size, so you will end up with a mapping containing roughly 192x144 features, which is going to look a whole lot like white noise. You should try disconnecting your pixel size from the actual size of the area of noise that you map, if you want to get anything useful.
