Yeah I am surprised its stable with that undervolt. Its almost like an rx 480 pretty much.
Well I had nine 390's this was the best one. it is in an open rig and quiet enough to watch tv fans a7 40% keep it cool enough.
And the 212 total watts of heat keeps the den a little warmer. it is usually too cool in the summer due to ac.
What I like about eth is I am fully roi'd . this rig earns 68.50 bucks per month before power my summer power is really high 18 cents. I spend 28.50 in power
So I net 40 dollars with little or no sound and just the right amount of heat.
I will be adding the 4 480's over the next 2 weeks. but I have to say I love running this r9 390 as a time filler for now.
Still running for about 12 hours.
I need to do a caveat about pc's .
I have an
iPad forgot the os but it is a mini three with and older os
3 mac minis last 3 os's
an i5 intel tablet window 10
a lap top windows 7
a linux pc
2 rasp pi's
6 pc's ready for video cards
parts for at least 2 more pc's.
so when I run a pc it does one thing mine on windows 7 with under volt and under clock this makes very stable cards that don't burn die or crash much. keeps heat and noise down and less work gpu mining. I also use better cpu's model t's when I can find them.
i-5 2500t
i-7 3770t
i-5 6400t
i-5 6500t
i-5 6600t
all good low power cpus.
others go for a few 6 card rigs that pushes the limits that can be okay and work out. but at 59 years old I just say fuck it my way at least feels a bit easier.
