Results of latency test, list of computers tested for use with LinuxCNC

Looks good, great for software stepgen, you going to go with Mesa or Parallel Port setup ?

If you are going with Mesa there should be no need to isolate a cpu and you'll only need the servo thread,no base thread required.

If not make sure to search the forums regarding PCIe Parallel Port cards, there's a lot of info there and no need to start a new thread.

2 cores????
How did you do that?
Ryzen 5 3600X has 6 cores and 12 threads
Did you by any chance limit processors to 1 in BIOS?

New here and thought I would share a test from an older gaming pc I plan to use after getting some good results with it. This test was done from the bootable usb iso. Took lots of bios fiddling to get it this low.

pc specs:

• cpu: amd ryzen 5 3600x
• mobo: asrock b450 pro4
• ram: 16gb ddr4
• gpu: amd rx570
• some random brand pcie wifi card
  
  

Thx for sharing this!
Did you move and/or resize the glxgears / browser window while runing the test?

I picked up a mesa 7i96s after reading about that which is nice.

In the overclocking section there was an option to reduce it to either 2 or 4 cores and I only tested with 2. The setting that actually gave the most improvement from my testing was setting a custom core pstate frequency and changing the cpu frequency/voltage from auto to a set value. There were a bunch of other random suspicious power management setting I turned off and it wasn't a very scientific process sadly lol.

I did move the gears/browser around and let it run for a couple hours.

Thx a ton! Also for the hints on

• overclocking section
• custom core pstate frequency
• cpu frequency/voltage

Have to get more knowledge on these, too.

Feel free to look through my bios settings, I took pictures of most settings for my own references. If you google the asrock b450 pro4 manual it explain what each setting does I think.
