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

[zelante]

Any plan to have a day a miner with real Failover support for cudaminer & ccminer ??
Cudamanager don't switch back to pool. Can't set rig for rent or use pool like nicehash without the failover  

Christian is busy with other more important stuffs. There was a quick&dirty hack with services and only avail for Windows. You can search it in this thread. If you don't like it then write it yourself. It's not difficult btw, it is just too boring that no one cares to write it.

Yep, Zelante has a failover .bat: https://github.com/KBomba/failover-ccminer-bat
No idea if he continued working on that, tbh.

With the profit switcher I'm writing, you should be able to turn off the profit switching and run on failover only. But I wonder how I could check if the stratum is back alive without launching a (competing) ccminer? Would a simple ping suffice to see if the host is back alive?

Last version here: https://github.com/zelante/NiceHashPrices
But i haven't rewrite batch file for it yet.

For those looking for a failover Pfool has a handy stratum proxy that can serve this purpose https://bitcointalk.org/index.php?topic=611338.0

To be honest after the Aachen mess (mountcoin/horizoncoin/orioncoin), I am a bit suspicious about cryptonote in general...

(quite frankly I had a better opinion of RWTH before that  )

"students from RWTH Aachen"

not employees, not doctorands, not professors.

heck, even I could enroll there (tuition is free in most German universities) and rightfully claim I am a student from RWTH Aachen

Yes, working like a charm.

Just wanted to say thanks again Christian. I am sending a "beer" your way later today! I know it's not too much compared to your earnings, but hopefully it counts for something

with new drivers my order of gpu is changed  
after call deviceQuery i get order 750ti 660ti 750ti (pci bus 3, pci bus 1, pci bus 2)  
but nvapi and msi afterburner show right order!
so my split screen ccminer doing wrong stats order for gpu now....

I ran into this a while back when I realized that even using the standard OC programs (Afterburner, PrecisionX, etc...) that they didn't always come up in the same order for me, and since the programs were sending the OC settings to each card based on that, I would get crashes.

So using the Devcon command exe I have it disable all the cards at startup and then turn them back on (enable) in a specific order by the card ID so they would always be in the same order.

Code:

taskkill /IM EVGAPrecision.exe /F

timeout /t 2 /nobreak > NUL

taskkill /IM EVGAVoltageTuner.exe /F

timeout /t 2 /nobreak > NUL

devcon disable *dev_1380

devcon enable "@PCI\VEN_10DE&DEV_1380&SUBSYS_8A9B1462&REV_A2\4&36135B44&0&00E2"
devcon enable "@PCI\VEN_10DE&DEV_1380&SUBSYS_8A9B1462&REV_A2\4&63638AD&0&0008"
devcon enable "@PCI\VEN_10DE&DEV_1380&SUBSYS_8A9B1462&REV_A2\4&2AF7FC6&0&00E3"
devcon enable "@PCI\VEN_10DE&DEV_1380&SUBSYS_31021462&REV_A2\4&25A57E32&0&00E0"
devcon enable "@PCI\VEN_10DE&DEV_1380&SUBSYS_31021462&REV_A2\4&6AE6995&0&00E4"
devcon enable "@PCI\VEN_10DE&DEV_1380&SUBSYS_8A9B1462&REV_A2\4&2DDC6CBB&0&00E1"

timeout /t 2 /nobreak > NUL

cd "C:\Program Files (x86)\EVGA Precision X"
start EVGAPrecision.exe
cd /

timeout /t 15 /nobreak > NUL

taskkill /IM EVGAPrecision.exe /F

timeout /t 2 /nobreak > NUL

taskkill /IM EVGAVoltageTuner.exe /F

timeout /t 2 /nobreak > NUL

exit

I have PrecisionX loading the settings on startup so they get applied everytime, but in case the machine is just doing a reset I kill off the processes, reset the cards, and restart the OC application before killing it off again.

Still can't connect more than 4 cards on my H81 BTC Pro Board. Five or six cards trips a reboot right after i start ccminer.

rolling back nvidia drivers, maybe that will sort it out.

I have the same problem with Linux, but not every H81 BTC Pro board. ccminer crashed when using 6 cards and only with a few algos, e.g. JPC,NIST5.
X11 works without problem. So I found out that not every H81 BTC Pro Board has the same build quality. The reboot indicates that something wrong with the power connects to the board.
I know it's really stupid but I tried a lot of combination last months to find the problem. (I have 6 H81 BTC Pro boards).
Some recommendations:
1. Change your board
2. Change your cards, some cards are heavily manufacture-overclock and cause trouble with the main board.
3. Riser could be a problem too.

I have the same H81 BTC board, and running win7 x64 it wasn't too hard... Not sure if you are on Win or Linux.

I was running just 4 cards for a few weeks, but when I went to add the newer two cards, I added them one at a time, and just rebooted it a few times.

The 'finding new hardware' process took forever to complete, but I just let windows find each card, then I started up the miner, saw that it was working, and then went about adding the 6th one the same way.

I did have to roll back a driver once after I installed it and it made mining slower, and that was essentially the same process, because when I fully removed the driver, all the cards went to discovery and re-installed using the driver that comes with the OS.

Then I stepped up to the newer Nvidia driver from there.

Hope that helps.

I also have EVERYTHING plugged in... all the MB plugs and powered risers using unpowered cards.

The cards pick up fine in Win7, and they all work fine until i put load on them with ccminer. They are EVGA 750ti Superclock GPU's and i'm using the Asrock risers. I had three 280x AMD gpu's on the board previously, and that worked fine. So it looks like it might be board issue.

Holy cow. BBR has double in price. 
Congratulation, Christian. I hope you hold your BBR well and cash out only slowly. Don't make some mistakes like with JPC and TAC .

I'm thinking about buying a H81 BTC Pro and hopefully I don't run into any issues.

Did you also give power to BOTH of the molex connectors on the motherboard? I know some people say "you don't need to if you're supplying power to the risers!" but it's always good to plug it in and test in case you haven't.

I invested in some XMR, BBR, and VTC yesterday, paid way too much by the looks of the lowering price, lost about 0.01btc over night in value

I've had similar issues with BTC pro h61 board. 5th card not being recognised, then when it does I get random ccMiner crashes. Seems to work better with 4 cards. At one point 5 cards run without issue. I think the boards are cheap and the quality suffers.

Could anyone recommend a decent quality mobo for 4 or 5 gpu?

[bigjme]

I have 4 in my asrock fatal1ty pro z77 board. Could easily get another.
Honestly i do think a lot of cheaper boards will suffer from issues. Dont forget your cpu does have a pci lane limit so plugging then directly in may not work so well

Did you not follow my "advice" from the other day, or following my advice is what got you into the red zone? 

For XMR I'd have my buy's set around 0.0046~0.0049.

(In any case, now grow some balls and hold, hold god damn it  )

when ccminer go in loop,(i can't even read too fast) it mean that the gpu are crashed?

[canigetanipa]

I run a H81 BTC Pro with 6 EVGA 750Ti's (without the 6-pin PCI-E power), I have 5 cards on 16x-1x powered risers, and the 1 card in the x16 slot on a 16x-16x unpowered riser. Rig has been running flawelessly for nearly 4 months now!

By the time i got back from work i was so tired i just got some. Obviously didn't pay full wack for them, i did save some. But i didnt pay as low as you suggested because i never would have got any xD
i did ppay pretty high though. This is what i paid

XMR - 0.00517994
BBR - 0.00233668
VTC - 0.0013739
