Gene, I had a thing like this a couple weeks ago with one of my office
computers. To make a long story short, the power supply capacitor was
preparing to blow its top which, apparently, caused ripple on the 5 V
supply line which was litterally counted by some chip on the mobo. The

Hi Sven;
I'm not saying you are wrong; and I thank you for posting the results of your
testing.
And today I did.
Running 2x2 GB RAM to maximize the I/O. Latency test, one glxgears and a

to 1024x768 and I was able

I meant to say lowering the resolution, of course.

I will say it. If its a 64 bit install, then it is not the rtai patched
kernel, and the results predictably will be poorer.
I'm not going to get into the Intel D525MW debate but I will run some
tests on my system soon and report the results.
The D525MW has been a great board for me. Zero failures and they just
run and run.
Reviewing Neweggs stock of ITX boards it is obvious that the Intel D525

The firmware for the D525MW has been revised a few times as I recall.
I had an issue with one board (I thought) and I reflashed the bios with
the latest firmware, but the problem was elsewhere.
I can watch HD video on my cell phone but not on these PC's.

Sven, 2 things you MUST do.
1. Turn off the hyper-threading in the bios.
2. Add isolcpus=1 to the end of the grub kernel line.
Oh yes I did that already. Latest BIOS firmware and running fastest

I assume that you guys using the D525MW board also is using a Mesa board. I
have two D525MW's and if you ask me their performance is really poor. I
don't have to push it at all to reach latency values way above 50 000 ns.
With a Mesa board yes, without

Since LinuxCNC doesn't really support 64bit that is kind of a moot point. Most
CNC machine applications don't need hi-res graphics, so most users are fine
with the default generic vesa driver graphics, at least that is all I'm using
on mine. All this was fine for me since the only thing the

Hi all,
I'm looking for an ITX-sized motherboard that will work well with linuxcnc.
I now have an Atom DN2800MT which has a lot of positives:
- powered from a single DC-jack
- passive cooling (just a slow case-fan is enough I assume)
- HDMI output
