Hi Sven; I'm not saying you are wrong; and I thank you for posting the results of your testing.

I still don't believe in you guys saying > that a D525MW is able to stay below 10 000 in a latency test. I don't think you changed the graphics driver just by lowering the latency. I have not done much Linux stuff in years, but I'm wondering what X graphics driver you are using? Can you force the graphics driver into some VGA totally software render mode? Also remote into it, and run it as a headless station. I should do this and see how it performs. Maybe next time I have a few hours around the house (hah! not in the next few weeks…) I'll run that test. > One thing though, I filled one of the boards with 8 GB RAM (2x4).

I don't think you'll be able to address over 4g via sw. Maybe they expect people to run windows, not Linux! Interesting that you can put the RAM in, as like you, I had assumed that it was not just a SW limit. Thanks; John A.
