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?! 
Just doned an fresh install of windows and install the 1809 ver. I was in old working good version 1709 and wanted to
refresh.
When im mining with lol, srb or other miner , if i bloq the copmputer after a while computer restarts.. wtf?
I install first last amd driver and 18.6.1 and the symptom is the same..
never happened this, and im using an single gpu on my desktop pc
Now i catch the BSOD and appears: whea uncorrectable error
Now i disable the turn monitor off after x minutes and seems work.
What should i look?
