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

What about failover support? Would really like to be able to lease rigs.

+1

I think I'd rather see this as a priority over X13, especially since X13 will probably settle down to X11-ish rates by the time someone gets this completed.

I don't have a whole lot to contribute, but I'd throw 0.02BTC into a bounty for an NVIDIA miner with cudaMiner/ccMiner performance and true failover support.  I'd up it to 0.03BTC if it added X13 support with a reasonable level of performance.

the priority is new stuff such as cryptonote, wild keccak, there is no real future in X13 (just look where is boostcoin now, it lasted a week)
Better mine mugatucoin (X11) or even better what I got as signature (no wait next week for this one   mine jackpot instead)

yes these two are promising. cryptonote is having an overly complicated CPU implementation
and is *very* memory hard with lots of random access. This limits your GPU advantage to maybe
factor 3-4 over CPUs.

wild keccak is interesting also, and it also has a memory hard component with a random scratchpad that grows with time. The advantage over CPUs is more significant, especially because that scratchpad is currently quite small (~5MB)

The weak point of these crypto currencies is a lack of simple to use windows installers with GUI wallets. This technology is for geeks only at this point.

Which probably makes them a bit more profitable to mine... 

[cbuchner1]

"Maxcoin style..."  if you know how to work it.

what algo's did you said again?

right guys, after my request earlier i have updated the submit configurations page, you have no idea how much work it took just show the version numbers like that!
good job i had a while at work with nothing to do. DAMN YOU sambiohazard!!!!!!!

let me know how it works guys, even if it means submitting loads of blank crap, just be sensible please

[Amph]

why the accepted share are displayed so fast, yeah first time with cudaminer  

also why http://cudamining.cc/url/configurations report ccminer 35 to use with jackpotalgo

i'm getting only 3.5MH/s with 1350 clock and mem, should i rise mem too?

Well, then a more flexible miner that can accept loading of various kernels is clearly the answer.

...no worry... we could deal this...maybe  
do many coins use wild keccak?

cryptonote... factor 3-4 over which cpu?
if we could reach 4-500h/s with a single 750ti it would be far more interessting than mining it with powerwasting R9 290x.

Another +1

Failover in ccminer would be my preference to see as well so my cards don't go idle mining against NiceHash.  If X13 makes it into the miner at some point, then multi-algo failover would be even better to have.  In the meantime, I'm seriously thinking of building a C# app that can monitor NiceHash and then start or kill miner processes based on which one is best to mine at the time.

[Amph]

it's ok to overclock(750ti) +300 vram from default settings?

[StuffOfInterest]

I've gone as high as +70 base / +400 ram on a EVGA 750 Ti SC under CudaMiner on Scrypt.  Much higher than that and it would crash after some time. I think I have two cards running at +50/+300 right now at home with ccminer on X11.  +300 definitely sounds doable unless you are running an algo which really heats up the card such as Scrypt-N.

[drkman]

Thanks it;s working 1,9-2 Mh rate can u help me with O.C settings

BTW, if you OC to much you'll notice that ccminer goes nuts with high hash rates (off the chart high), will crash or you'll see strange errors.  Just back off a bit.
Hope this helps,

Does anyone know the fix again for this problem.  My multicard rig like clockwork will go nuts with highhashrates after some time.  This is running stock clocks.  At the minimum is there a ccminer command that can restart it every 2 hours or so?  I can't find the page that discussed this solution.

How many GPU's and what OS?

Windows 8.1, AMD A6, 8gb Ram, usb powered risers.  (usb risers are plugged into 4pin molex because i'm not sure if they work without being plugged in).

-I know it happens with 4 or 5 cards in the rigs (haven't reduced the cards to 1 or 2 to see if they can hash stable).  Happens on both a 500watt corsair and 600watt corsair rig.  Used both the last 2 latest Nvidia drivers, no change.

The other thing that happens and others have noticed as well is that 1 or more of the 750ti's will downclock to a very low clock speed.  The 2 symptoms are probably related.

I thought there was some programming fix for this but it's lost in the thread.
EDIT:  I've studied it and essentially one of the cards is crapping out or dropping the driver and then makes the card drop to 500mhz clock.  This then causes all the other cards to lose stratum and the hashing goes wild for all the other cards. The card downclocking is the number 1 card position in EVGA precision.  Does that mean it is in the first riser spot or the last x16 PCIe slot?

EDIT 2:  Removing the 1st x1 usb riser card along with removing the last x16 onboard card and going down to 3 cards seems to not recreate the problem.  If there is anyone who has 4, 5 or even 6 750ti cards stable using ccminer on X11 can you please tell me your entire setup and config?  Thanks.

UPDATE:  I think I found most of the problem for me.  I was letting ccminer choose the number of cards/threads to use by not using the -t command.  Once I began putting in -t and telling it how many threads to use, it became much more stable on both of the rigs. I also switched 1 of the rigs to all be the exact same brand and model number and that rig is now rock solid.  On the 2nd rig which is a mixed brand rig, I still get the 1st card in precisionx that always downclocks to 500mhz, but the overall rig stays hashing normally for over a day now.  Now I just need to figure out the problem with that 1 card and that might be a power issue.  Feel much better now.    UPDATE 2 - Solved the single downclocking card.  It seems the x16 PCI-e wasn't fully locked, so resetting the card on the board and ensuring it clicked locked fixed that low hashing card problem so check those basic things if anyone has similar weird issues.

don't expect too much from the 750ti. Looking at the way the R9 290x works it uses around 3Gb of vram, so assuming it gets implemented in a similar way (which we will never know  ) you won't get these sort of performance with the 750ti. This will certainly be also a problem for the 880.
But the titan Z should do very well

How do you think a workstation card might do for cryptonote coins.  Those cards can have 4gb+ of ram.

workstation card ? You mean the pro nvidia card (forgot their names) ? (depends how the memory is shared between the gpu's, I guess)

ok 4-500h/s was just a thought out into the blue... but if the 750ti could make 200h/s it would be more than interessting.
GPU's are easy to scale and use less energy.

but doesn't matter at all... I will be happy *sing* with everything crazy C&C will publish.

no much luck at the moment with the new(est) crytptonote Aeon, not a single block
