Hardware latency tests, used PC's

Ok Tyler how's this.....

You already have it.

The ISO I linked to before is for both the Odroid H2+ & PC. The "special" bit is the driver for the 2.5Gb Realtek NIC. Apart from that it's just the same.

Oh sweet! Is the Realtek NIC driver already installed?
I didn't catch the H2 in the file name.
Awesome, can't wait to get the Odroid and report back!
Thanks so much.

Tyler,
I can get some of these pcs dirt cheap. So, would you mind running this on your dell 780 and put the ".hw" file in this thread ?

Oh, and for the odroid h2+ too, please?

Thanks a ton

That was with 2GB of RAM, adding another 2GB made it much better and usable.
For software stepping it needs an older RTAI kernel to work, new ones do not work on them, it has a nice latency so parallel port can be used.
For Mesa boards it will need at least 4GB of RAM to have usable latency with new Preempt-RT kernels, use the 4.9 as it has the best latency on it.

tommylight chimed it with the skinny on the Optiplex, 2GB more RAM and it should be dandy.
I'll be posting my progress with the Odroid h2+ once I recieve it.
I'll start with sir Beagle's latest iso.

Thanks for this senior tommylight. I'm going to take whack at setting up an Odroid and keep the Optiplex as a test (after adding to more GB RAM).
