What does DMD-Groestl do on a 980?
here on my last x64 release (to test a bug report that i cant reproduce...)
8170k on the 750ti black
21.09M on the 970 at 1300MHz
params : -i 19 -a dmd-gr --cpu-priority 3 -o stratum+tcp://dmdpool.digsys.bg:3333 -u Epsy.dmd -p x
sp version defaults are -i 23/24 which put the hashrate at 22.49MH but make windows ui unusable
Submitted another improvement.. more than 10% faster on the gtx 970
New hashrates Myriad groestl.
750ti: 14.400 MHASH
970: 44.360 MHASH
Compared to the opensource AMD miner:
Speed with Myriad-Groestl (Myriadcoin, Saffroncoin, Futurecoin) mining:
R9 290 - 34.2 MH/s

Two questions for chrysophylax:
Its obvious your team has studied your hardware setup thoroughly to have the best efficiency so you will be able to tell me what I haven't considered in my question and my mistakes.
- In your mining farm setup why have you opted for gtx 750ti cards instead of mining asics? Don't asics have more power efficiency and higher hashrates specially in SHA-256 cryptocoins?
Wouldn't be more profitable in terms of power consumption to mine SHA-256 altcoins for example and then exchange them for your desired cryptocoin or choosing what algorythm to mine in terms of the most profitable in a given time based on their difficulty and exchange rate of the corresponding altcoin? - Have you thought about using mineral oil solution or freon to cool your setup? Colleges are using this technique and its totally safe using the right compounds. This way you don't have to worry about cables and air flow and reduce the power consumption. If going pro mining why don't go all the way?
Even gives you leeway to overclock and play with temperatures.

I am not crysx, but I can help answer these two questions:
1) NONE of us are mining SHA-256 algorithm. You are of course correct about ASICs dominating SHA-256, or any other algorithm for which ASICs exist. (Scrypt) [Are there others?]
Which is exactly why we don't mine any algo with ASICs.
We are GPU miners and this is a thread about the fastest nVidia-based GPU's using SP's optimized miner.
2) That oil-cooling stuff is indeed awesome, but the implementation costs would likely destroy any chance of achieving ROI.
(Public) Colleges have plenty of (public) funds to spend and they don't calculate ROI like us GPU miners must do.
Energy is quite expensive in France: 0.144€/kWh, which makes Nvidia the only cards that can ROI. And it still takes them around 8 months...
ROI in 240 days.
if you have 240 GPU's you will ROI everyday.
ROI 1 gpu per day.
With 240 980ti's (40 rigs), $750 a day.
submitted a small speedup in myriad groestl. more is comming
Second question, my calculations don't match yours. I find 970s to be better than 750Tis with version 51 of ccminer. As an example, here are two 6 GPUs rigs running Quark algo:
6 750Tis at 155€, 5730kH, 60W
450W PSU 43€
hashrate 34380, power usage 360W, price 973€. 35.33kH/€, 95.5kH/W
6 970 at 365€, 16200kH, 160W
1200W PSU 275€
hashrate 97200, power usage 960W, price 2465€. 39.43kH/€, 101.25kH/W
The efficiency of 970s looks even better when you consider it takes three rigs of 750ti's to get
the same hash rate as one rig of 970's. Add the cost of two more CPUs, motherboards, drams,
hard drives (or other boot devices), psus and cases, and the power they consume.
I don't know euro pricing but I can guess the power overhead of each rig to be 100W.
That would make 3(360+100) W for the 3 750ti rigs and 960+100 W for the 970 rig.
The 750ti rigs would have a higher total hash rate of 103140 KH/s vs the 970s at 97200.
3 x 6 x 750ti: 74.7 KH/W
1 x 6 x 970: 91.7 KH/W
Smaller cards have a higher cost and power overhead due to lower density while bigger cards
have a steeper price curve. The 970 looks to be in the sweet spot. The 970 can also compete
on space with the availability of an LP version.
whats your take on the 980ti? ...
if it seems to be the best value - then it may be worth the effort of replacing the 750ti cards ...
It really depends on price and whether the price premium for the 980ti is a good tradeoff
for the increased density. I don't have CAD pricing for the 980ti but the 980 has
a higher cost/hash than the 750ti, 960 & 970.
I expect power efficiency to be comaparable to the rest of the
9xx family
Thank you sp
I think once you start your builds on the 980ti the performance will go way up....and so do the donations.

I think the 980ti card is to expensive for me to buy. Please ask NVIDIA to send me a card for free
And continue to donate some beers.
A few bucks is bether than nothing..
Everything depend on one thing; your electicity cost. If you have expensive electricity in your area, you will never hit ROI, if you have average electricity cost then you probably won't ROI and if you have very cheap electricity go for it.
That's one of the things I'm trying to solve since here in my country the price of electricity makes any mining unprofitable (0,18 USD KWh). I'm studying the option of an aerogenerator and a battery rack.Epsylon3/tpruvot still builds for compute 3.0 & 3.5 last time I checked. Or you could compile ccminer yourself.
Thanks for the info joblo. I'll check it out. btw - ours are open air systems like yours but in a custom built 'shelving unit' - which is difficult to maintain at the moment ... we are still designing the open frame ( to make it a modular system ) - and morphing it into a closed frame that uses air vacuum ( rather than just open air ) to dissipate heat which will also reduce noise at the same time ...

Expensive? In Italy we pay way more than 0.2, even 0.3 at times. And the more you use, the more you pay (per KW/h).
Ouch, that's rough! I was comparing with US prices that go as low 0.1$
Your ROI times must be painful :-/
I only mine during winter, so I can at least use the heat produced :-/

My rig is built around an Asrock H81 pro BTC and a Celeron G1840 (Haswell) which has a very low power usage. I also use a USB stick instead of a HDD for the same reason. That brings the consumption to 12W for the empty rig (measured from the wall). So the difference between 750 and 970 is not that steep for me, but an all-970 rig still wins by around 5%.
A nice point of the PSU I quoted (Cooler Master V1200 platinum) is that it has 12 6+2 pcie ports out of the box, so you don't need adapters. But, as crysx said, it will probably look like a spaghetti nightmare: my first rig is named (very originally) miner1, the second one will be named firehazard1 :-)
I have two questions for you. Until now, I've used the windforce OC 750Tis because they are totally overbuilt. Max temp is 60°C, with fans running at 40%, which makes them almost silent. Really, I have 4 of these running 24/7 on an open bench, on my desk and they don't bother me. How noisy are these smaller cards? My guess is one smaller fan must have to run faster and make more noise.

we pick up the gigabyte 750ti oc lp for about $165AUD ... this card is the lp version ( low profile ) specific card NOT the powered one ... it is small and can do everything that the powered one can do - except exchange firmware as far as i know ... its dense also - for the 750ti that is ...Second question, my calculations don't match yours.

power is a major factor also ... with this card as opposed to the 9xx series - it uses such little power that the overall cost of the psu is quite small also ( smaller psu as opposed to larger ones cost astonishingly MUCH less ) ...
the biggest thing for us in this regard ( and im talking on a farm level basis ) is the build time and cabling effort required ... these cards do not have any other power connectors outside of the normal risers power ...
less cabling is less tiebacks of cables which is better airflow and less maintenance headaches ...
so in essence - its an 'overall' take on the cards that make it better for us in the farm ... thats all really ...
of course - if your electricity costs are cheap as dirt - then it obviously makes sense to max out the hashrate as best you can within the price range you can budget ... but the build and maintenance is a big part of what we take into consideration also ...
btw - ours are open air systems like yours but in a custom built 'shelving unit' - which is difficult to maintain at the moment ... we are still designing the open frame ( to make it a modular system ) - and morphing it into a closed frame that uses air vacuum ( rather than just open air ) to dissipate heat which will also reduce noise at the same time ...
so far - the development system is coming along fine ... a little more tweaking and a rebuild will see it finished in the coming weeks ...
#crysx
OK, so the factors I was missing are cable management, airflow and general maintenance time. That makes sense.
At your scale, adding and 8pin + 6pin to each card must be a nightmare...
I also guess that noise levels are non-issues for you, since you probably don't live next to your farm.
Thanks
But currently the reference 980ti card running sp-mod 51 is hashing at 23230 KHASH on standard clocks, while a standard 750ti easily does 5,7mhash.
Around 4,07 times faster. But I think the -i setting can improve the hashrate. With more memory a higher intensity than the default is possible.
The official manufacturer’s suggested retail price of Nvidia’s GeForce GTX 980 Ti for the U.K. is £549 including value added tax (VAT), which is $752.

gigabyte 750ti oc lp cards seem to be the way we will lean towards on a price per hash per watt situation ...
though the only issue ( i think was mentioned by bensam a little bit ago ) is the density of the cards on a single system ...
but for the that reason above - the gigabyte 750ti oc lp ( and they are really a small card - low profile ) means that we will continue with that card until a better one comes out - then determine whether a full upgrade is viable ...
the way the development that ccminer has been going on the sp fork - it seems the smaller cards will be around for a lot longer ...
now to get our internet links back and stable so we can get back to mining / work ...

It's not, system costs exponentially drive up the price of mining rigs. Even a barebones one will tack a lot on to each card. It really comes down to density, price of cards, and PSUs.
750tis are a bit more efficient and you get more hash for your buck, but it's basically 3 750tis per 970.

a 6x 980ti rig will mine quark@130MHASH (sp-mod 51)
250W*6 +100 = use around 1600W (you'll need 2 psu's)
82.25KHASH per watt.
And the cost of buying the hardware will be enormous...
