I did a DDR3 layout, sure there's a lot to think about if you want it to work in extreme temperatures or with lots of EMI. But for hobbyist use its essentially get the right trace width for the PCB material using an online impedance calculator, and then length match and match the count of vias for all your traces of the same bus and don't exceed the length restrictions. Don't forget to have a good ground plane. This will work 99% of the time. Its time consuming and annoying but not rocket science.
