[ANN] cudaMiner & ccMiner CUDA based mining applications [Windows/Linux/MacOSX]

[Dotcommie]

What MOST people can expect:
750 = 260khs

750ti = 300khs

I can likely go more on the 750s, but my 750ti's seem to max at about 305-310 now with the newest cudaminer and high overclocks.  Previously I was only able to get 288-295 consistently.

What do you mean by "newest cudaminer"?  I'm slowing closing in on 300khs with a 750Ti using the February release on stock bios.  Each day I push the clocks up a bit more and then leave it to test for stability.  I'm still on the February release because I also have a 650 Ti BOOST in the same machine and its performance went down with newer versions due to the known CUDA library issue.  May have to try running two instances of cudaMiner (one old and one new) if the newer version can take the 750 Ti higher.

I believe it was compiled from the sources updated 4/15.  I think Christian mentioned it should help the pcie bandwidth issue when using risers.  It seems to have helped a little on my amd rig and my socket 1155 intel, but it helped most on my 1150 i3 rig with the EVGA FTW cards with raised TDP.  Went from 1765ish to 1855ish I think.

I own a Asus Direct GTX 770 2GB
The rate is around 330-380 khash/s
I Also Am running a Nvidia GTX 650 Ti
The Rate is around 150-170 khash/s

I was able to get my GTX 770 Up to 400khash/s Alone  When overclocking it, But when coupled with the 650Ti i was getting crashes.

Personally i think you would be better to spend the extra £10 or so and get the Ti, as it will get more performance. How much more i am unsure

1,560khs for a 6x750 rig at about $720 in gpus (ones i got were $120)

1,800khs for a 6x750Ti rig at about $900 in gpus (@$150, mine were $165 on average though, so $990)

**Also keep in mind the 750s are supposed to use less power and I've never tried modifying the bios at all**

ok, thank you
currently the price at my place, 750 is $140 is, 750 Ti is $170ish

I'm hoping to get GTX 760 second hand for around $210 and SLI'd with my gaming rig (I get ~310kh/s with my 760) but the power usage won't decrease much from 5850+6670 combo

I believe most have said you cannot 'SLI' two cards together and mine with them, so may want to work that into the equation or check into it further.

I believe the computer only sees SLI'd cards as a single unit, so only the first one would mine. I haven't done it or even tried, but I swear I read that someplace.

Good luck!

[bigjme]

You are right. Sli is useless for mining. Hence why we use 750Ti's which can not do sli.
Not the only reason but i had to mention it

ooo and for anyone interested, i just boosted my MSI GTX 750Ti's to 1.4GHz and their running stable mining groestl.
Right now the increase from 1.3GHz to 1.4GHz and made a large improvement from
3.1MH/s to 3.4MH/s, all with an increased power load of 2W!

so to state, each of my cards now consumes 2w more power, however produces almost 300khash/s more. So a 9% improvement for a 2% power increase. And the shares being submitted seem to be more stable aswell. If it gives stability issues i will be sure to let you all know. Performance with the new groestl release when its out will be very interesting. i wonder if overclocks will keep.

Thats a question actually, have you noticed an increase/decrease in TDP under the un-released groestl code? As if you havent, overclocks should remain good, and if you see triple performance, my overclock could get triple benefit (0.9MH/s) on each card

wow thanks... i didn't know that
guess i'll just get 750/Ti then

looks like its best card to mine efficiently for now

[bigjme]

The 800 series launch might not be what a lot of us expected. It seems that atleast some of the 800 series will be using the same chips as the 700 series not the maxwell series. But rumours have said the 880 will have around a 200W tdp, and be maxwell, but may have memory bandwidth issues as its only using a 256bit channel instead of the 356bit like tye 780Ti. So memory intense stuff may be an issue

Ooo and a 740, 730, and 720 is coming out. Noone buy them please, their re-badged 600 series cards

[ivanlabrie]

880 is the one to get...memory bandwidth isn't an issue for mining, latency is.

[atc1]

So..uhh..whatcha guys mining now? I'm mining Groestl but that's at a loss. 

[bigjme]

My groestl mining isnt too bad. Not great but not bad

[djm34]

So..uhh..whatcha guys mining now? I'm mining Groestl but that's at a loss. 

To be honest at the moment, beside going blindly on any new coin, it is difficult to see something really interesting...
Waiting for BlackDragon which looks good.
Juggalow might be profitable (but it is X11)
Blue, Yellow might be interesting (Green also .... I am even not trolling   ) for fast dump.

So..uhh..whatcha guys mining now? I'm mining Groestl but that's at a loss. 

I understand UTC might be a good profit until the reward drop at block 240000 (and possibly delaying your sells for after the reward drops).
Haven't done the math myself yet...

Ok so i decided to push my cards a little bit more.
Just pushed one all 3 of my 750Ti's up to 1.45GHz and i am now mining groestl at a steady 3.55MH/s per card

now totalling 10.65MH/s and i still have not hit the limit. This boost uses an extra 1W of power for all 3 cards, so 0.33W per card for an extra 150KH/s



ignore the low hash's, they were failed from days ago, as this has been running some while, but my maximums are all accepted and doing good  

also for anyone interested, i changed my view for seeing the web interface

I believe it was compiled from the sources updated 4/15.  I think Christian mentioned it should help the pcie bandwidth issue when using risers.  It seems to have helped a little on my amd rig and my socket 1155 intel, but it helped most on my 1150 i3 rig with the EVGA FTW cards with raised TDP.  Went from 1765ish to 1855ish I think.

Is the new cudaminer available? I can't find it. Can someone share a link? I'm looking forward to see issue with pci risers x1 fixed, there is 20kh difference now between cards with same settings on x16 and x1

Here you go: http://cryptomining-blog.com/1998-download-the-latest-build-from-source-of-cudaminer-for-windows/

And it solved the problems for me. I did have to run the version 2014-2-28 for 670 though. For some reason this hew version makes it run slower. But my 750ti's are humming along like they were before.

That's what I did as well.  I run the 2-28 version for my 650 Ti BOOST and the newer version for my 750 Ti.  Did see a slight (less than 1%) bump in khs on Scrypt with the new version using the same clock settings.  I'm still closing in on the 300khs speed, up to 297khs running stable at 65C now.

I was able to close the gap between x16 and 1x risers a little more by adjusting the batch size parameter. I found that, by choosing a smaller number than the default (1024), I could yield an additional 10.86 khash/s (+3.9% increase) from each card. Batch sizes that were a factor of the scrypt kernel thread count (768) seemed to achieve the highest speedup. I also ran tests with different launch configs but found little difference. YMMV

Here are some benchmarks I ran against a single EVGA Superclocked 750ti (factory default) on a 1x USB riser, 10 minute averages:

Code:

cudaminer --algo scrypt --benchmark -b $BATCH_SIZE --launch-config T10x24 --interactive 0 --texture-cache 1 --single-memory 1 --hash-parallel 2 --lookup-gap 1 --time-limit 600

Code:

+-------+----------+
| batch |  khash/s |
+=======+==========+
|  192  |  284.475 |
+-------+----------+
|  384  |  284.153 |
+-------+----------+
|  128  |  282.400 |

So what settings are you using for your 750ti? I am running the EVGA 02G-P4-3753-KR. My miner seems to crash all the time and I have just now figured out a more stable situation...and as I typed that it crashed after about 9 hours of running. my miner does this for not sure how long (image below) and continues to mine with the remaining cards that didn't crash until the PC completely crashed and I powercycle it manually.

I am running 335.23 Drivers and the 2014-2-28 miner and my settings look like this. Will paste them in when I get home and turn my computer back on. And now that I see the new CudaMiner is available (Why is it not on the 1st post in this forum) I will download and check what results I am getting and see if they keep crashing.

This version does not work with scryp-jane !!!

Does anyone know the solution ?
