from the killawatt 807watts
nothing to brag about for 5 x 480s at 28.xx mhs
the newer GPUs like single 5700XT can do twice the hash at lower watts
--- snip ---
Software still reporting a total of ~664?
Yeah, the 5700xt is basically a double card, lol. Now that I've learned a bit with the dozen Polaris cards I have, I have an appetite for more efficiency going forward.
SMOS still reports the same 664w
the mobo, ram, cpu etc takes about 142w
I can only conclude that the 80ish watts is not correct, since it totals only 408w.
it should be 664w div 5 = avg aropund 130ish per GPU, which aint that great for only 28mhs
I will keep these 470s,480s aside and offline for now (i have total 240 + 60 of them)
All my 1080tis, 1070tis, Vegas are mining ETH for a while now
A few 1060 and P106-100 rigs are also just up and running.
When ETH goes parabolic, I will squeeze the melons out of the 470,480s - at that time electricty wont be hard to justify.
What kind of motherboard and CPU is this? It should take 40 watts or so not 140. If you got some old Quad-core intel CPU then I guess it makes sense. However for most low power celeron processors it seems high.
With 5 GPUs of Polaris GPUs your consumption should be ~650 Watts or so. 800 Watts seems high, most likely due to your CPU+Mobo. Are you sure they are all undervolted to 900mV at least?
