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

A bit off topic, but I have a card which keeps crashing not just the miner, but the whole computer after a few minutes/hours randomly;
The card is a 780 Ti sitting with 5 x 750 Ti and whatever I do or whichever fork I use, it crashes the miner which start stressing the cpu at 100% (at which point the GPU usage is 0% for all cards) and after a few minutes without forcibly closing the miner, they PC just freezes, no BSOD, no restart, just completely loses interactivity. If I close the miner before that, the System process completely hogs one CPU core (25%, i3) and the PC becomes very unresponsive and it can barely do anything until a restart. Tried different risers, a few different drivers, replaced the GPU BIOS, downclocked but none of that helped. It only does that during mining and the PSU can't be the culprit.

The event log wasn't much of a help:
The description for Event ID 13 from source nvlddmkm cannot be found.
Graphics Exception: ESR 0x506224=0x80000041 0x506228=0x10a40f 0x50622c=0x280 0x506234=0x0
NVRM: Graphics TEX Exception on (GPC 0, TPC 4):     TEX NACK / Page Fault

How big and what kind of PSU do you have?

Just curious I had a problem with one before that caused all kinds of issues until I replaced it.

EVGA SuperNOVA G2 1300W but also tried it with a 850W PSU.

Talking about elecricity, mine just got increased to around .16.

Forgetting the price of the card, is the 970 and the 980 the new 750ti? Meaning watts per hash. If you had a free choice, would you take 3 750ti or 1 970 or 1 980 keeping in mind watts per hash only.

I believe the single 970 wins if your using enough 750tis to need to MB's but its been a while

Thank you bigjme. That's for my next rig.
Haven't seen you around for a while.  

It has been a while. Work is hectic and I'm working 7 days most weeks now

Have you tried running Precision (that is what I use) or something similar and then when this happens see if it still shows 6 active cards?

Maybe you have 1 card going bad. If this is the case you  should see 5 cards instead of 6 cards in the read out (at least I would with Precision).

Just trying some ideas.

I only mentioned the power supply earlier because I was having problems also, freezing, shut downs, losing cards (4 cards working instead of 5). Finally narrowed mine down to the PSU one day accidentally touching it while changing risers and it was burning hot.

Precision doesn't show anything out of the ordinary, except if I try to restart it, it won't run. I had issues with cards before, but this one brings the whole computer to it's knees. I might just give it to my brother for gaming as it's working perfectly in games/benchmarks and I don't game much anymore.

Undervolting does not hurt cards.

Thanks, i'll have to try it.

Undervolting helps them live longer and run cooler, actually.

now if undervolting, you need to down clock otherwise it will crash very often...
actually instead of undervolting, you can decrease the max tdp as everything is taken care by the card...

thanks djm

hi people!

quick one,

are there still (with a major crash in btc price) any profitable coins for 750ti with a non-free (0.14$) price of 1 kw.

Cheers!

profit is really low... talkcoin is in the list of the profitable coin   (with a buy volume 0.5btc  )
feathercoin, negative profit... ouch !!! (now, I don't understand why they are making new scrypt strains... it has always been a bad algo at that level...)

edit: must be noted that jpc, coinshield or other new algo aren't taken into account (not sure if jpc is profitable though... and we know for the moment coinshield isn't...)

FTC is actually hella profitable right now on AMD 

you mean if you have free electricity ?
few numbers ?

[skunk]

for those of you in need to heat up their room and without the time to search for the next profitable coin, past weekend i've put together a bash script that switches between 3 multipools (trademybit, yaamp and nicehash) and their algos in function of advertised profitability (by pool's api itself).
the script is self explanatory, just adjust hashing rates, pool's user/pass/apikey where applicable and miner's paths.
warning: don't expect huge profits since profitability on multipools is very low lately...

Did you know they switched algo?

yes, and whattomine.com as well.
currently based on what they wrote, the daily profit to mine FTC (neoscrypt) is smaller than the electricity cost.
(at the moment over 125kh/s profit 0.59USD electricity cost 0.89USD so basically it is a net profit of -0.3USD  )

that's why if you had some numbers to share...

I assume this is for people running Linux?
For those running Windows (everything from XP to Win8 ), you can just use Miner Control to do the same thing (automatic profitability-based switching), except that it includes six multipools to select/mine from.  NiceHash/WestHash (you can use weighting to favor the one closer to you), TradeMyBit, YAAMP, WafflePool, and LTCRabbit (if you actually have some reason to be mining Scrypt, such as if you own some ASICs).  As with Skunk's bash code, you will still need to edit Miner Control's config file with your own hashrates, power consumption, electricity cost, the miners you use (CudaMiner, ccMiner, etc), and pool login infos, to be able to use it effectively.
And ask Skunk also said, don't expect huge profits, since profitability is down all across the board with the BTC crash. 
In any case, it's good to know that there are two good tools for this kind of mining, for both Windows and Linux users.

Forgetting the price of the card, is the 970 and the 980 the new 750ti? Meaning watts per hash. If you had a free choice, would you take 3 750ti or 1 970 or 1 980 keeping in mind watts per hash only.

Its why i started an open source campain :

don't forget to sent me money too... my btc address is in the signature... take advantage of the low btc rate  
I can do some maxwell 2 tricks too (and actually I did it already with coinshield  )

I think we will see soon some gpudevcoin with ICO on bittrex

I undervolted the 290X and dropped volts even more on the rest. Results:

Code:

Freya, mining Neoscrypt (custom kernel):
Total draw: 560W
Total hash: 850kh/s
	270X: 115kh/s @ 975/1500 & 975mV
	280X: 229kh/s @ 950/1500 & 975mV
	290X: 273kh/s @ 900/1500 & 1112.5mV
	7950: 231kh/s @ 950/1500 & 975mV
Settings:
	Intensity 15, worksize 64 for all
	TC 16384 for 270X, 49152 for 280X & 290X, and 32768 for 7950
	GPU threads 1 for 270X, 280X, and 7950, and 2 for 290X

Still profitable.

may-be I will look into neoscrypt at some point... currently there isn't much of anything profitable... (but for the moment I am optimizing some stuff... )

someone know, how to set solo mine from renting to a virtual machine or even host? it works locally, but i can't get it to work from remote, i opened the port with firewall, but still nothing

As far as I know most renting sites only support stratum.

yeah, i pointed it to a stratum proxy, java one, this https://bitcointalk.org/index.php?topic=611338.0

Are you the only user of that miner?

Hi folks,

Long time since my last post here (new job consuming my time last 4 months).

I was mining XCN (5 x 750 TIs rig) for some time, but some days ago I realized it was not even paying the electricity itself.
So I started looking for new options and did not find any interesting one.

I've been reading the last pages, but, the talk evoluted to a "advanced programming side" that I'm not used to and I could not find a good "direction" to point my rig (if still there's any)

Is JPC still profitable?
Is the moment to replace my 750 for 9xx?
What the "fuzz" about this Neocrypt algo? As far as I read there's no NVIDIA specific miner yet, right?

Sorry for so much questions and thanks in advance... ;-)
