I have 19,3 GHs model and first thing was to lower the frequency. I set it to 506 Mhz where I get average 18200 GHs, the power consumption is around 1130W. I find those settings are the sweetspot regarding HW errors.
HW errors appears mostly in the second hashboard, arround 200 a day, also third hashboard is around 4 Celsius degrees hotter than first and second - can these be fixed with changing voltage ?
I heard from some folks, that undervolting the graphical cards for mining could harm them in longterm (if this is true at all) - do you think it is the same with asics ? I'm mainly conserned about loosing warranty - can Bitmain obtain any info from my D3 if there are any custom firmwares (antbleed is probably history now) ?
thanks in advance for answers,
best regards to you and to the rest of community
Blissz , anybody ?
