can't run y-cruncher


Recommended Posts

Errors in the console usually mean hardware instability. The most common one is "coefficient is too large".


I don't know what chip you have, but the usual case is a Haswell chip that is stable enough for normal applications and "light" benchmarks, but not stable enough for AVX. This creates the impression that the program is buggy when in reality the hardware was never stable in the first place.


Haswell with AVX-stability is by far the most common case. But I've seen it on other chips as well. My AMD box gets this a lot when I try to run my 1866 memory at stock. The IMC limits it to 1333, so 1866 is technically an overclock. But y-cruncher seems to be the only app that can expose the (slight) instability at 1866 MHz.
