I should also say that you should disconnect power and let the 7I39 cool as it very likely will overheat and do a thermal shutdown if overloaded this way. The thermal shutdown is designed to protect the 7I39 in cases like this but is not 100% reliable depending on the circumstances > > >> >> If you can't fix it, you don't own it. >> http://www.ifixit.com/Manifesto >> >> ------------------------------------------------------------------------------ >> Keep yourself connected to Go Parallel: >> INSIGHTS What's next for parallel hardware, programming and related areas? >> Interviews and blogs by thought leaders keep you ahead of the curve. >> http://goparallel.sourceforge.net >> _______________________________________________ >> Emc-users mailing list >> [email protected] >> https://lists.sourceforge.net/lists/listinfo/emc-users >> > > Peter Wallace > Mesa Electronics > > (\__/) > (='.'=) This is Bunny.
