It is a well known fact that smi tool shows way too low numbers.

actually not they are right i then measured with wattmeter, total for the system was 520w with cpu running 25%, 2 additional fan(120mm) on the motherboard, the motherboard itself, the psu+the ssd and the ram(2x4)

cpu alone is 15w at 25%-30% peak, ram are like 3w, the two fan are like other 2-3w, the ssd, is another 2-3w the psu is like 10w, and the motherboard is at least 30w probably more

this is a total of 70w, 520-70 = 450/3(i'm running 3 970) = 150w each, now from the web it seems that a motherboard can consume more than 30w in overloaded, plus add that each g1 gaming has 3 fan and not two

you need then to remove another 20w at least, so 140w each is the best number you can get

Did a test run with latest 368.22 drivers (W7 x64) and I must say I am really surprised it actually works now, numbers are on par with my power meter.

I still need 175-195w to 22MH though, 140w can be done with 19-20MH. Tested on coinotron stratum, recheck value 4000.

My undervoltaged 390 can do 27MHz with 160 W. If you undervolt the 970, can you do better?

BS man i have a ton of 390s -120mv undervolt with claymore dual miner they still pull 240 watts, if i was solo mining eth i would gain at most 50 watts thats still 190 watts

Which would be more profitable: ETH cloud mining or using my own hardware?

you can not compare like this, because different card have different consumption

i mean your card probably have two fan only and less component than a g1 gaming

i just tested and i can do 20MH with only 124w, now from those 124 you need to remove the fact that g1 gaming have 3 fan and a more power hungry pcb, because of the bigger heatsink

With same type of memory, core&mem speed they all have more or less the same power consumption.

Bigger than 6+6pin power connectors just let you use more power and bigger heatsinks and more fans give tools for getting rid of that increased heat.

980 G1 is just as efficient at 20MH as Strix 970.

that "more or less" can make the difference here, since we are talking about a very small difference, about 10w per card

this is what i'm talking about

If you pay $0.1/ Kwh your mining rev/ profit would be (according to whattomine):

GTX970 20MH/120w $2.62/ 2.33 per day
AMD390 30MH/230w $3.93/ 3.38 per day

I just can't see how 10w could be a gamechanger here.

You can't undervolt 970, you just lower the limit you let GPU "spend" power and nvidiamagic does it all for you.

Let me guess, -200mV and 1000 core with that 390? I am running mine 30MH+0.6GH with 260w...

I think nano is different. The chips are selected specially so that the power consumption is very low.

So basically, it is better to buy the cheap non "gaming" cards with less components and undervolt and get better efficiency.

yeah like the 970 mini itx, 1 fan only smaller pcb and heatsink, will consume much less while performing similar, but with less potential oc

same for 380 mini itx, and nano, that's why the nano is the best right now

yes but now i know exactly how much one card consume, the system apparently consume 70w when three card are mining

each card 147w mining at 22MH, same thing as 390, so those who were saying that amd was better, were wrong

possible lower with a reference 970 due to less components on board plus less fan, 140w estimate

I have 5x R9 390 XFX cards. 137 MHz with 870W from the wall, so that is 6.35J /MH, that is better than the 970.

not with reference card, it depend on the type of card, with a reference card that have 1 fan only and a smaller pcb you consume less

mine are g1 gaming you are running 390 that have probably two fan only and the pcb is smaller with less component, that's why you consume less

they are equal in the end, i can estimate a consumption of 140w with a reference 970 at 22MH so 5 x 140 +70w of the whole system(i have two fan added for cooling and my cpu is at 25% + 8giga ram)

so total is 700w, plus the 70w system, = 770w vs your 870w at 132MH vs 137MH, not better at all, only nano is better 970 and 390 are equal

The wattmeter isn't useless, as it shows the entire comsumption of the SYSTEM - which is a lot more applicable to figuring profitability than JUST the card (or cards) IN the system.
CPUs and motherboards and ram and drives etc eat power TOO, and if the system isn't being used for anything else that MATTERS.

I would prefer to use the voltage mod, to reduce the voltage a bit, then use the MSI Afterburner.
