Thanks for posting this! Glad it is buttery smooth! Sorry to burst your bubble, but you probably aren't going to notice the upgrade to 1333 from 1066, purely for LinuxCNC work. I'm at a latency of 30000ns, running off a spinning disk (what is that?), and it's fine!! If you're gaming or running a lot of computational work, the extra memory bandwidth can be a few % improvement on most any system (some processors/GPU's are more memory bandwidth limited than others of course, this falls into that category some with the integrated graphics), but again, LinuxCNC is a light load!
After getting the new memory in there I ran another latency test and got 6219 ns latency running it hard, so it did help a little bit. I am sure like you said that it will have little to no effect for milling. But if you have to buy memory anyway, I could not find better memory for the money anywhere.
