gt730 is a kepler compute 3.0 card. It's not supported by ccminer sp_ mod ...
Thanks rednoW for the fast response. Any chance there's a modded version of ccminer valid for x64 systems and humble (60$) videocards like mine? ![Cheesy](https://bitcointalk.org/Smileys/default/cheesy.gif) I'm thinking about buying an Antminer S5 and get in a multipool but since I'm pretty noob at this I'm taking my time searching for info and making sure it won't get obsolete after 2 months, what altcoins are the most stable longterm, if it's best to mine low diff coins and exchange for bitcoins exclusively or diversify and pick two or three promising altcoins, etc. That kind of thing and meanwhile I use this gt 730 to mine dmd. I've been like a month reading articles and the different altcoins and its prety confusing for a newbie... Hope I will get the hang of it in time and make a wise decision.

Mining bitcoin is a decomposed dusty skeleton of a dead horse.
Altcoins are still OK to mine.

Merged a change from the tpruvot branch. When the stratum connection was lost, ccminer kept mining even if the internet connection was down. Now ccminer it wil sleep and save electricity.
Great thank you sp. Did you take into consideration of changing the disconnect reconnect time from 30 seconds to 10 seconds on your next build ? That would help alot when renting. ![Wink](https://bitcointalk.org/Smileys/default/wink.gif)

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.
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
Can you elaborate on what you think makes 750Ti the better option? Are my figures wrong? Or is there something I don't take into account, like a better overclock on 750?
I'd guess because prices are somewhat different on a per country basis. For example, a year ago I bought my 750 Ti's for 121€ or 0.6 BTC but now I could only get them for around 147€ or 0.729 BTC and a 970 would cost me 384€ or 1.9 BTC so everybody kind of have to play with the numbers aveilable to them.

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.

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.

Why don't you run 3 970 cards and 3 750ti cards on one rig, Then you can buy a cheaper 850W PSU. The different 970 cards have different powerusage. Some cards have 2 6 pin poweradapters, while other cards have 8+6 pin. I have noticed that on the cards with 2*6 pin, the latest sp-mod might cause the cards to trottle and performance is lost. (because it needs more power) This can be solved by a bios update, or overclocking/downclocking. The gtx 960 can also be considered. The gtx 960 is just a few dollars more expensive than the 750ti, but they give a 80% higher hashrate and use 100% more power. (around 120W)

This meens less updates on the ccminer. I have pushed Quark on the AMD 280x from 1.7 MHASH to 4,5MHASH on standard clocks. Still a long way to go to reach the wolf0 performance ![Wink](https://bitcointalk.org/Smileys/default/wink.gif)

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...

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 ...

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.

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.

Thank you sp I think once you start your builds on the 980ti the performance will go way up....and so do the donations. ![Wink](https://bitcointalk.org/Smileys/default/wink.gif)

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.
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
Can you elaborate on what you think makes 750Ti the better option? Are my figures wrong? Or is there something I don't take into account, like a better overclock on 750?
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 ... 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
