4.69w/MHs, good !

Actually, 12.32w/MHs with my poor 280x rig Angry

a gtx 1070 is 3.7w/MH and 1060 will be the same or a bit worse, like 4 ratio

1070 is more expensive yes but who care you can sell it 3 months later and losing nothing

Lets say both rigs hashes 143 mhs total.

If gtx 1070 gets 3.7w/MHs according to you, then that power at the wall would be 529 watts.

The rx 480 at 4.69w/MHs will be about 670 watts at the wall.

That is only 141 watts difference. I don't think the start up cost of a (6) rig of gtx 1070 would justify the 141 watts difference when compared to a start up cost of a (6) rig rx 480.

For me, a faster ROI is better when less capital is spent to start off with.

i agree but you need to account the resale value, and almost no one mentions it when talking about roi, but it's a part of the roi itself

in fact the real investment on which you need to roi is the difference between the price at which you bought the card and the one at witch you sell them later, not the initial investment

also you didn't take into account the scale factor, having 3.7 at 24MH is different than having 3.7 ratio at 27MH

the 1070 does 3.7 ratio at 27MH at the very least

you sound stupid dude must be a lifer NVIDA or employee or something just shut up rx 480 is better for Eth and its not even close, now if youre saying you want the 1070 for mining other Algos thats a different story but
your broken record act is getting annoying.

Wrong also btw on resale , rx 480s are hard to find actually harder to find than 1070s right now , I checked Newegg,Microcenter and Best buy and they dont have any rx 480 for sale but guess what they have 1070s for sale by the dozen.

Checking ebay the rx 480 lowest price is like $300 usd so you can actually make a profit if you want reselling them

do you even research any of the BS you spew ?

I've been testing a lot lately with different wattman settings and so far, this is the best I can get. My main goal was to lower the power use as most as I can without impacting the hashrate too much and also lowering the heat and noise. So I just want to share what I have been using now to help others.

I have 6x XFX 480 4gb models. At first, I flashed them all to 8gb, but I flashed them all back to 4gb, due to the 4gb having 1750 memory clock instead of 2000 memory clock, which will lower power usage without impacting hashrate that much (probably due to better memory timing straps).

I just change state 7 to 900, voltage for gpu and memory to 800, power limit -30%, and change the fan speed and target temperature to my liking's.

Here is my GPU-Z showing my settings stuck even after flashing from a 4gb to 8gb and back to 4gb.

Here is me running Claymore 4.7 with ETH mining only and showing a stable hashrate of almost 24 mhs per card with GPU-Z graph.

Here is my whole rig power usage with 6x RX 480.

So far, I'm pretty happy with the results with the whole rig only needing about 670 watts at the wall.

If anyone else can figure out a way to lower power usage even further and still stay close to 24 mhs per card, please share. Thanks.
