I was reading the last 40 pages (i've been out a while) and I was wondering, why is there is so little info about power efficiency?.

There was such a discussion, was it really more than 40 pages ago?

It came down to 750ti vs 970 with the 970 getting some credit for lower rig overhead, it needs fewer rigs to produce the
same hash rate as 750ti's.

The 750ti shines on lyra2v2 giving it a clear edge on that algo, IMO. Although the 750ti is generally
thought to be a more efficient card it's edge isn't so clear at the system level with most algos.

Your thoughts welcome.

[sp_]

The 970 can mine more efficient if you lower the TDP of the card with the nvidia-smi tool. The gigabyte G1 970 has a tdp of 250W while the reference card has 150W. Instead of selling the card you can lower the TDP to 180W.

I was reading the last 40 pages (i've been out a while) and I was wondering, why is there is so little info about power efficiency?.
isn't the most important factor in mining nowadays?, specially today that is barely profitable?
power here is getting expensive fast, and unless i found the most efficient way, i will be out of business soon!.

As mining is in the shitter, donations are low as well. I just gave you 5% in the quark algo and 5% in the lyra2v2 algo on compute 5.2 devices.

5% increase in the hashrate with the same watt doesn't seem to be much, but your profit will increase with more than 5%

If your powercost is 90% of the Mining revenue, a 5% faster miner will give you 30% higher profit.

Please donate to get more hash. (and recieve private profitable miners if you reach 0.1 BTC (spreadcoin/penta/cryptonight (0.1 BTC each))

sp_ how much do you want for your quark private miner? or DJM? or even x11 and Lyra2REv2

Not for sale. But if djm34 sell his kernal I might sell it.

lol, you might have to wait a bit before selling then  

Just to summarize a bit the way I do things, for me for a sell to be profitable it has to reflect, somehow,
the time I spent in coding (regardless of the coin value ) hence if the coin value is low,
it wouldn't be profitable for a miner to buy from me or it wouldn't be profitable for me to sell below my time/money equivalent  
(and would be bad business practices as well since when I work for a coin dev I charge along that time/money equivalent).

so for the moment, it isn't for sale...

also as already said multiple times: trust is important for me... (private miners are sold in priority to people I can trust)

Just wait till it's unprofitable then release it for free or for a very low price. I bet that will appeal to the majority of miners and makes sure you maximize your profits! XD

You have to consider you guys aren't the only ones making miners. Private kernels devs exist, especially for big farms. Whole reason people still mine x11.

guess you forgot to read (as usual) what you are quoting...
if it isn't profitable to release then it isn't released, and the fast code may be eventually used elsewhere
(other coins, other algorithms) to keep the edge... hence no hurry as far as I am concerned

And you missed the part where if you don't release anything you're neither profiting nor helping anyone else... As you've done in the last six months.

There is no 'ROI' on code. It's not the same thing as hardware. You can sell as many copies as you want and the demand for it is only reduced by the desire to want it. So if there is a competing product or they can get it for free. But since there are 'no' products available, you aren't really accomplishing anything.

This is why a open market for kernels would be a really great idea for alt-coin mining. Hopefully Nicehash will eventually do this. It wouldn't require that much development time.

nice to see you back around here induktor!

since Quark mining is right about at the cost it takes to mine, i only have one or two rigs going, mostly for space heaters since the temp is dropping nicely outside.

all the other algos are in the shitter. i think BTC needs a nice big pump.

Too bad there aren't good miners to buy.

[pallas]

ROI on developed software: developing takes time and time is money (I could do something else and get paid for it). So yes, there is "roi".
I surely don't expect to roi on my opensource software, and am very far from it. Different story with private works.

... and you missed my last sentence  
there isn't a ROI on code per se, but it is up to me to decide if it is worth (money-wise/time-investment) to release new code.
New coding technique, new developpement are lost to me, as soon as they are released, I lose the advantage I have over the competition. (take an industry they publish patent over new tech long in advance, in order they do not lose the time they spent in R&D regardless if they use it in a new product or not). Hence, what I do here is more or less the same.
(that was exactly what I said in my last sentence, in my previous message you forgot to read  )

Updated to r68 and lowered intensity to 22.9

What cards/clocks do you have?
With my Gigabyte's OC to 1400Mhz I get only 7,2Mh/s.

In those two rigs i have EVGA FTW cards.
7.2Mhs with Gigabyte cards are probably really good.
I have a Gigabyte Windforce 750Ti that hardly makes 6.8-6.9Mhs. And it is not stable there.

There is a difference in the different 750ti cards, but most of them overclock very nicely.

Man... I pay 110 euro for Chieftec 850 bronze here, and 135 for same but gold

For a 6x 750ti rig you only need a 500W psu. You get a gold rated for 0.1BTC

[djm34]

which will last half a year (been there...)
for info 0.1btc == 40euros

750W BRONZE--

If you use a bigger CPU, and have six 6-pin 750ti's that overclock, you'll pull closer to 600W.  I'll side with DJM34 here.       --scryptr

i've never had any mining rig powered by anything less than an 80% gold unit. i think it's worth the minor extra expense from bronze to gold.

Thank you, that's what I was saying. It is worth 0.1 BTC more for few watts and percents more

[induktor]

nice to see you back around here induktor!

since Quark mining is right about at the cost it takes to mine, i only have one or two rigs going, mostly for space heaters since the temp is dropping nicely outside.

all the other algos are in the shitter. i think BTC needs a nice big pump.

Howdy
thanks!, glad to be back, i love mining, I missed it.
indeed... in the shitter, that's why we need to do something about it!, I have 2 choices, learn to code or work on power systems, since I'm a hardware guy, i choose the latter .

I too have half of my miners offline, because in this part of the planet is summer, and it's killing me with 35C @ 90% humidity, so AC + miners == maxing out circuit braker   , not a good deal

I plan to release here another kopiemtu mod with the newer drivers and cuda 7.5 to match the new sp_ releases, since you, sp_, looks like not longer gonna release anything else with cuda 6.5, I knew that it will happen sooner or later so, so I got work to do  

There was such a discussion, was it really more than 40 pages ago?

It came down to 750ti vs 970 with the 970 getting some credit for lower rig overhead, it needs fewer rigs to produce the
same hash rate as 750ti's.

The 750ti shines on lyra2v2 giving it a clear edge on that algo, IMO. Although the 750ti is generally
thought to be a more efficient card it's edge isn't so clear at the system level with most algos.

felt like 40 pages hehe

I know rig overhead is costly but i have computers, hardware is not a problem because it's one time thing, my concern is power usage, so I strictly concentrate in power usage regardless of how many rigs do I need, even with the use of more rigs which ever CPU and mobo eats power, still is a lot lower than GTX 970, like you said, specially in lyra2v2 but also in quark.

another reason is temperature, GTX970 works at a very high temperature (75C with 25C ambient, even with the three coolers, insane!) , I don't like that, as an electronic tech, i know temp kill rigs badly!, it's only a matter of time!.

Don't get me wrong Gigabyte GTX 970 G1 where fantastic cards, I love them, power density is awesome, they are extremely stable, beautiful (i know, I'm a nerd, can't help it) but when it comes down to power efficient, it's like 40% more than 750Ti (including the rig overhead!).

I haven't tested GTX 980 much, if someone has efficiency numbers (real ones, measured at the wall with a decent power meter) will love to know!.

Hi sp_ how do you get such a low power usage per rig?, amazing!, and you use windows so that includes 8W of the hard drive, are you including the percentage of the computer power consumption as well?  (cards + computer W /amount of cards?)
are you measuring at the wall?, are you taking into consideration active/reactive power (I say W because it's easier but i actually measure VA) (I mean, are you measuring using a true-RMS power meter?) I use a APPA A18plus clamp meter.

[RANT]
windows is totally out of the question, stability issues, freezes, weird problems at startup, cards dropping without reason every now and then, i tried that a couple of years ago with the AMD farm and drive me crazy!, it wasn't a day that I didn't have 1 rig with problems, with linux, i can mine for months without a single hiccup, also manage them is a lot easier, and I can run everything from a flash drive, I don't even care about powering them off, just cut off the power, i know that flash storage+linux works 100% all the time!, also it's way easier to clone every miner.

If I use windows, 30% of the time it will launch the startup repair and I will need to plug in a monitor and KBD to say NO, geez!. (and here power outages are very frecuent, so i need to be sure that rigs will power on automagically every single time when I'm not there.
[/RANT]
also, mining, kills hard drives like crazy, unless use SSD which are expensive here.

Someone mention that I should use GOLD PSUs, i will love it but price of GOLD psu here are impossible, not to mention that are very difficult to find, specially the small (500W 600W) ones.

example:
a 1000W sentey bronce PSU costs here 370 dollars
a 1000W sentey platinum PSU costs here 620 dollars

that's mad!, almost twice the price!.

I will try your latest version as soon as I have a working version with cuda 7.5 and last driver
tomorrow I will look for the platium PSU and test it to see the difference, I only bought one because of the price.
will post results, thank you for the data!.
