But the 16 threads on optimal mode sure crunch through those OGR work units nicely. The other problem is the dnetc apps are pretty well optimized to extract about all that can be sucked out of the cpu/gpu's and that really gets them warmed up. I don't noticed the generated heat out of the boinc projects like collatz, asteroids, nfs to the same degree as the dnetc stuff. So one might say why keep crunching dnetc, however I've been crunching them for years and years and I like those projects...... So I guess it's just keep living with the heat. lol
