The idle power is 25W, the full load power is 320W, so simplistically, we think the mining uses about 295W, or 147W each card.

Er, no. The system less the gpu's is not at 25W when mining; the PSU is operating at a much higher load, there are always inefficiencies (most are only 80-85%), and I can't monitor the PSU I/O by itself, only calculate it. Also, there are case fans ramped up adding to system load, each draws at least 5-10W running at 60% or so. Add it all up and the non-gpu-related draw is much higher, I add it up to about 60W.

I think it is similar efficiency. the difference is very small. 7970 is 3-4 year's old card.

7970 20MH/140 = 0.142.
970: 20.75/147 = 0.141.

Bad math; it's 20.75/115 = .18, but I'd rather do it the other way (W/MH). We're only looking at the card power here, but you're including system power in your figure and don't appear to be doing the same with your 7970...

Let's try to keep our numbers in perspective. I'm not advocating buying GTX cards over AMD for obvious reasons, just saying that a state of the art gaming PC can mine pretty well and efficiently. Grin

But that extract fan power consumption is due to the mining as well. So we have to take that in to account.

i have almost 22(21.6 average) at 150w-160w(tdp 60%)

22/155 = 0.141. So Your 970 (?) is the same efficiency as the above AMD and nVida.

I am wondering how good is the 970 after undervolting.

yeah same thing, in the end, with my 970, but better than old card

PLEASE consider moving away from Dwarfpool. They now control over 43% of all hashing power! That is out of hand.

http://etherscan.io/stats/miner?range=7

If you believe in Ethereum, you must believe in the fact that decentralization is VITAL and resource centralization is no good for anyone.

ethpool has stratum proxy support if that is a potential migration drawback.

yeah i agree but the earning will suffer then, i've tried supernova for now, it does not seems so bad compared to dwarf

Checked the UPS readout with some known power draws (different wattage lightbulbs etc.) and it checks out just fine, so that's not the question.

So, system idle readout is about 20-25W, all case/gpu fans low or off. There's 10 fans total; 3 case, 2 cpu, one ps, and the four on the pair of gpu's. I can't assume the gpu fan power is included in the %TDP figure shown by monitoring, which is important because I'm running them at ~60% to keep things under 70C.

Nevertheless, with mem clock @ 3800 (P0 state +300), core +50 (base boost=1440 +50=1490 but both cards do not run this rate for whatever reason, I've seen some explanations), gpu fans set 60%@65C, the %TDP is 75% for one and 80% for the other = 112W avg, so let's call it 225W for the pair. Load reported by the UPS shows 310-320W. If the fans are drawing additional power above that (not being included in %TDP as assumed), then all the case fans, system, and PSU efficiency (80% corsair 850W) would likely make up the difference of 90W or so.

Reported hash rate is 41.5MH/s (fluctuates between 40 and 43 as is typical).

I'm not about to go further in diagnosing this, it's not that important to me and I don't have the equipment/software to pick apart every component, so there's some assumptions here. I'd still like someone to explain how 41.5MH/s @ 320W total is "impossible" with this system. Roll Eyes

From idle 20-25W to mining 310-320W makes sense to me. Rest is about ethminer speed reporting, I tried with only two cards TDP 80% and reported speed was 40.8 OR 44.8MH

GPU mining 2014 and 2015 was all about being efficient, so far 2016 looks different. Right now I'm not interested about power consumption, I was only complaining because these days there are loads of first rig builders who are reading these threads. Soon there would be threads about howto build 600W 110MH nvidia rigs for ETH mining and why it doesn't want to start mining or reboots randomly...

Happy mining to everyone!

I was looking into buying a GTX970, is the 90W figure for power draw something you actually measured (i.e with a Kill-a-watt) or just the stated power draw from the manufacturer?

Earlier in this thread I mentioned using a UPS that has wattage readout. You can get individual card power draw with software like afterburner, precision X, etc.

Using afterburner I oc'd the pair of 970's gpu ~1440MHz, mem ~3700MHz, wattage is ~115 each, gpu temps 65-70C, total system @UPS is 330W, getting 43MH/s. These are EVGA 3975-KR SSC AC2+

Factory o/c settings they run 90W each @ 1440gpu/3000mem, total system @270W, get 38MH/s. Not sure the extra o/c is worth it...

Thanks for this, that is the information I was looking for. I had missed the part before where you mentioned you used a meter, too many posts on here quote the cards factory rated spec so that why I wasn't sure which it was until now.

GTX 970 mining [email protected] is hitting every possible limit it has. There is absolutely no way you can do that with 115W.

His total system power consumption is 330W, if the PC system power consumption is 60W, so the 2 cards use 270W or 135W each.

135w is possible, because i've done it by lowering the tdp to 50 or less, but the hashrate will be lower too, so it's pointless like i said above

actually i think it's better to consume more but produce more coins per day, than the opposite

i've lowered the tdp, now it consume at max 170w, but the ratio is the same, if i lower more to 130-150w, the hashrate will suffer, so there is actually no point in lowering it, besides having cool temp(now 64)

150w = 1250 megahash, 170w = 1300 megahash, mining decred

Sounds about right.

This thread is about ETH mining profitability so opposite to DCR the most important thing with nvidia & ETH is overclock your memory. Put your card to P0 state to get access to memory speeds above 3005 MHz, OC your mem, play with core and tdp. Find combination that works best for you. Sometimes insane combinations give best hash/ watt performance.

No offense, mate!

I must be wrong with your power consumption. Some 970's have 225w or 250w bios from factory.

Nvflash and Maxwell bios tweaker are you friends if you really want to know what your card has eaten. Just flash no limit bios and post your wattage after that

There is no point in going so far as to screw with the card's bios. I'm not a professional gaming overclocker, but we're not playing video games where losing a few pixels here and there doesn't matter; submitting good data is all that matters. Acceleration of mining ethereum has less to do with pushing the architecture's balls to the wall, sweating high wattage/temps for nothing, producing bad nonces and getting no submits.

These cards run mem at 3700MHz+ with no errors, keeping temps in the mid 60's (read longevity), and produce 21MH on very low wattage.

Had to take a look at SSC Gaming ACX 2.0+ bios power table.
