so (I think) I made some huge progress and thought I share the results:

the terminus has been running rock solid and cool at around 1Th/s (thanks to minefarmbuy help)

the sweet spot for me was setting 5 on the vcore or 440mV and 900 freq (edit: I am also experimenting with 875 and 850 seeing that the r606 always seems to stabilize at 825 by itself)

(edit2: I am getting almost the same hashrate with freq 750 and volt 6 so I am running it this way, way cooler and less power)

temps look great, the heatsinks sit at 29C (above) and 33C (below), air coming out almost feel "cold" ! room temp is around 24C


the newpacs (I have four), well, these little fuckers are putting up a fight, but also I think I might be on the way to figure it out (hopefully with your help)

what did it for me was isolating (got it from the thread not my idea) and running separate instances on cgminer

problem is if I run one or two sticks they run great (98-99 WU)

when I start the third instance is where they all start to jump all over the place and usually getting 40 to 50 % WU with spikes to 80 % ( at 200-225-250 and even at 100 freq)

can anyone point me to why that is ? I though it might be a power related problem but even when I just run the gekko 7 port hub without the terminus I get the same results, I don't get it !

any help very much appreciated !

setup is a psu corsair CS550M powering only a mb and cpu running ubuntu 18.04, no video card

what do you guys think ? it's really driving me crazy

EDIT: I get better rate with 2 sticks instead of 4 so I ended up unplugging 2 ! still I would like to run all four ..
