As far as I know the one you need runs at 50Mhz so you'll need a 040/40 with some good cooling.
I can't imagine it increasing the speed significantly though as it still lacks direct fastram access for the CPU.
They come with the needed CPU and cooling. For $100 or so, probably cheaper now, it's a good upgrade for an 3640. It won't fix A3640 design problems but you do get a much faster processor.
