Things are working when the CPU's are kept busy from what I've read in the various notes. The hang-ups are during idle times. "the system ends up locking up or crashing as soon as you stress it" does not sound like a matching context. That a slower RAM speed might help idle behave correctly is interesting given the Zen and Ryzen dependence on RAM speed for the speed of its internal interconnect-fabric's operation. I'll note that, if one goes through the referenced Linux exchanges about this, Ryzen Threadripper's examples are also reported to have the problem. === Mark Millard marklmi at yahoo.com ( markmi at dsl-only.net is going away in 2018-Feb, late) _______________________________________________ freebsd-stable@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
