EWBF's CUDA Zcash miner

[geezypeats]

I'm running into a problem where, rarely, the miner will need to restart my gpu's, and they do get restarted successfully (supposedly), but they just start producing 0 sol/s.  I have --eexit set to 3, with shutdown -r -t 00 after, but this doesn't seem to trigger the miner to exit, and thus the shutdown line doesn't trigger.  

Is there anyway to somehow detect that the gpu's are running, but producing 0 sol/s and make the miner exit and restart the computer?

EWBF's miner actually took 5-6% DevFee instead of the stated 2%. I checked the log file out of curiosity and counted all accepted vs DevFee:

GPU0   1703 accepted
GPU1   1772 accepted
GPU2   1791 accepted
GPU3   1723 accepted

Total: 6989 accepted
DevFee: 362 instances

362 / 6989   = 0.05179567892402346544570038632136 = 5.1%


On a second run I got the following:

Total: 6159 accepted
DevFee: 347 instances

347 / 6159   = 0.05634031498619905828868322779672 = 5.6%


I was doing around 1800 sol/s with EWBF and around 1700 sol/s with NiceHash's Excavator. So I stopped using EWBF since there's no difference running Excavator over this.

You are a miner and i think you must know what's mean mining difficulty.
If the difficulty of the devfee pool is lower than the difficulty of your pool, than the number of devfee shares will be above 2%, only because the cost of each devfee share is lower than the cost of each share of your pool.
Try to run miner on this pool: http://dwarfpool.com/zec and use the port with low difficulty 3334, wait for about an hour, and then calculate the number of shares.
And yes of course you can use --fee 0 if you wish...

I'm new to mining and started just a week ago. And yes, you're right - I just realized I didn't consider difficulty and just counted results and ratios. That's a plausible explanation for the results and in this case I don't have any problems with it.

Any chance the download instructions could include a linux command line to download the miner?

example:

wget "https://drive.google.com/uc?export=download&id=0B9EPp8NdigFiLVVnZDhjc2Vyc3c" -O zecminer_0.3b.tar.gz
gunzip zecminer_0.3b.tar.gz
tar -xf zecminer_0.3b.tar

It would be nice if I could point people to those instructions to pick up and run your miner - if they are using Linux (I now have the instructions, but think they belong in the main page so people trust the instructions..)

Thanks !

remove port number from server,

./miner --server us1-zcash.flypool.org --user t1Zp2sW7u79zga8JWqQTqqHRxJJCjuPjUnF.rig1 --pass x --port 3333 --cuda_devices 0 1 2 3 4

I have Internet connection :p that's what I'm posting with... and mining ETH works just fine

440W for 6x1060GTX 6GB  = 1500 sol (power 55  +150 + 500/). Silent   Yes not the fastest but had to set  low because of $l$ctricity. 440W is at the wall

AHHH thank you so much man

[infofront]

I know Eth miners often dual mine. Is it possible to do it on Zec without a dual mining program? Like running EWBF for zec + ccminer for decred?

Anybody here using G1 Gaming 1060's?
What's the temps on them?

[BadAstroZA]

Just started and getting about 240 Sol/s on:

• GeForce GTX 970 with 4GB
• Windows 7 Ultimate 64 bit
• 8GB RAM
• Intel i5-4690K @ 3.5GHz

Performance:


GPU-Z status:


Lots to learn about this still, but managed to get going on the https://zec.suprnova.cc Asian pool. Let's see how we do.

I'm using Jaxx for my ZCash wallet - any other suggestions?

EDIT: Not sure how to get my image to display as a picture and not a URL.

Could be that GTX 670 does not have the correct CUDA architecture and is simply not possible to use this Zcash miner?

Perhaps someone with more knowledge than I could confirm.

I figured that out, nonetheless the router could have been blocking the miner from accessing the web.

I think that you have to use an older version that support GTX 670. I do not know which version it is though.

Hi, yes new release coming soon. What new api features do you want to see?

Timestamps inside of miner.log would be nice also. (so could see time also when gpu has been restarted, etc.)

And somesort of watchdog (like on claymores miner, if gpu is stuck for X time, run specified command/script)

btw, thanks for good and stable miner, and is there any info on new version, speed improvement, features, etc. Or do we just have to wait until you release it

Dear EWBF,

is it possible to make dual mining ZEC + something?
