Mach4 does require more RAM and CPU power than Mach3. It depends on which version of Windows you are using and if you are in Mach3 or Mach4. While Windows 11 is not in that list, it does work with Mach4 and the ESS. Windows 64 bit will support the following maximum amounts of RAM (which is typically much more RAM than your mother board will allow): However, with Windows 7 or newer, we recommend 6 GB and prefer 8GB of RAM or more to give a better user experience. Back with Windows XP, you could run Mach3 with 2 GB to 4 GB of RAM quite acceptably. The main disadvantage of 32 bit Windows is that you can only have a maximum of 4 GB of RAM (minus some stolen by video resources and other areas of the OS).

The only disadvantage to 64 bit Windows is that Mach cannot control a parallel port, but Mach can control our SmoothSteppers, so you won't need to control a parallel port. You may use either 32 bit or 64 bit Windows with a SmoothStepper.Ħ4 bit Windows allows your computer to use more than 4 GB of RAM, and the ESS (Ethernet SmoothStepper) and USS (USB SmoothStepper) will run with 32 bit AND 64 bit Windows.
