i don't know the why, but my y-cruncher always have a problem when i try to benchmark, the most of the times the error is "gerneric exception "

"error code:1" and "error code:2"

In console? It's just means that the core unstable and needs more voltage

Helpful thread on this topic - if you have questions beyond the information there, it might be helpful to ask them there and also give information about hardware and OS you use

now another error, "coefficient is too large"

i installed another version of java and the bugs stopped, sorry for the inconvenience

my pc was with two problems, java and enough ram to run the bench, i was with 6gb and need of 5 free but windows used the rest, so i catched my friend ram and now its time to bench

Good luck

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.
