Do you have any AMD material that calls out "factory OC'd" boost values being unstable and unsuitable for serious compute? Also, isn't distributed computing based on the idea of using idle consumer hardware and getting some benefit out of it? It would be a pretty serious change in direction to say that only server class hardware was desirable for these projects.
Errm, earlier I merely expressed my confusion of why a CPU at this clock configuration was undervolted and then used for sustained computation. [#239]

I don't know what server CPUs have to do with this. I did not bring server CPUs into this discussion.

So… is there, by any chance, some AMD material on the application of their new Curve Optimizer in the area of scientific computing and engineering?

Here is the A10-7870k host with integrated Gpu and R250X Gpu work units. The R250X is just a little bit faster than the integrated Gpu (around 80 seconds faster, give or take). Interestingly, I’m seeing validation errors off the GPUs as well.

So what's the average time for at least 5 WUs?
