why i get so many rejected shares on hiveos?BUT with the same setting(core 1200/mem 2000/volt 875,--strategy=1 --opencl-kernels=4 --opencl-launch=512x32) every thing are good on win10......

on luckypool rejected shares shows "Incorrect share"，but on mining.blue it show "low difficult share"

i tryed everything,like --opencl-kernels 0-4,or --opencl-launch 256x0.384x0 512x0 512x32 256x32 384x32,--strategy=0/1  still get 2%-5% rejected shares

here is some log,it happened on every rig,not just this one。
