Re: [JCE]Fast & stable CN/v8/Heavy/Tube/XHV miner, CPU+GPU, Vega56 1800+ RX580 1200+
Why my core i7-8700k,when mine cryptonight sometimes starts with good hashrate ~=400 h/S but sometimes start with 270h/S and i have to do several restarts of miner ( or open multiple instances) to make it to maximum and sometimes i quit and i leave it in the low hashrate..
Yes, that's stange! I had this issue, too, on several i7-8700 "Coffee Lake". Interestingly never on AMD Ryzen and not with "Haswell" based Intel systems. Perhaps a "secret" Coffee Lake hw-prefetching mechanism, which sometimes gets into play and sometimes not?!
