Stratum Based Open Source ZEC ZCASH GPU Miner - ZOGMINER

[giagge]

Here's a compiled Windows version of nheqminer for CPU and GPU:

https://github.com/ocminer/nheqminer/releases/tag/0.2a

can you upload the 3a for your pool? it hash faster

Yes pls compile v3a for nvidia cuda windows work on stratum+tcp://zec-eu.suprnova.cc:2142 pls ? .

nheqminer_v0.3a_suprnova is producing only invalid shares it seems. Thousands of "unconfirmed shares" in the dashboard. In the terminal it says something like "low difficulty share".
That's with R9 Nano under Win7 64bit and 15.12 drivers.

Hi!

If I downloaded the compiled version for windows and want to try this out with my CPU and GPU (Nvidia) should I create a .bat file? And what should it contain?

Been some time since I've mined on my own PC lol.

Just edit the .bat 1-8 in the folder and try everyone if some working your a lucky one

How can enable more than 1 card, with -cd option, only 1 card start?

-cd 0 1 2 3 4 5 to enable all 6 cards

Is this the option for zogminer ??

Can I use this miner with my old macbook pro (model from 2010)? Or will it not work?
(I installed Linux in Virtual Box, so no problems with OsX...)

I have 4 rx480 in one rig. Do I have to run 4 instance of zcash-miner like below??

./src/zcash-miner -G -S=0 -stratum="stratum+tcp://stratum.zcash.nicehash.com:3357" -user=t1xxxxxxxxxxx -password=x
./src/zcash-miner -G -S=1 -stratum="stratum+tcp://stratum.zcash.nicehash.com:3357" -user=t1xxxxxxxxxxx -password=x
./src/zcash-miner -G -S=2 -stratum="stratum+tcp://stratum.zcash.nicehash.com:3357" -user=t1xxxxxxxxxxx -password=x
./src/zcash-miner -G -S=3 -stratum="stratum+tcp://stratum.zcash.nicehash.com:3357" -user=t1xxxxxxxxxxx -password=x

You could try, but in general, any kind of mining on a laptop is a bad idea. They are not built for long term cpu-crunching and can be damaged due to overheating.
If you would like to try for the learning experience, sure go right ahead and try mining for a half an hour. The macbook will not survive a long term mining though and the components or motherboard could get damaged.

Hello everyone

First of all, thanks a lot for all the work and effort for creating this software. I am running Zogminer with Ubuntu 14.04, installation went fine thanks to a few good guides.

I've been doing some testing and I have two questions so far:

I'm not sure how to mine with 2 gpu's at once. Right now I have two terminals running. I executed these commands:

Code:

homas@thomas-B85M-D3H:~/wolf-xmr-miner-master/zcash/zogminer$ ./src/zcash-miner -G -S=0 -stratum="stratum+tcp://eu1-zcash.flypool.org:3333" -user=zcaZo9xjVvCTysk27gLzDizYMLntF4cBffHKGa8JHtPijjP5pdthNbsXizAQTicgsSpfWyyPXcT6vBnRZw4QEwApBc23RD5

and

Code:

thomas@thomas-B85M-D3H:~/wolf-xmr-miner-master/zcash/zogminer$ ./src/zcash-miner -G -S=1 -stratum="stratum+tcp://eu1-zcash.flypool.org:3333" -user=zcaZo9xjVvCTysk27gLzDizYMLntF4cBffHKGa8JHtPijjP5pdthNbsXizAQTicgsSpfWyyPXcT6vBnRZw4QEwApBc23RD5

                   ^


Kernel run took 94 ms. (12.1063 H/s)

I don't understand the error on line 288. Anything I can do about that? Am I actually mining under these circumstances with both cards?

- Sometimes I seem to be getting an error:

Code:

Kernel run took 114 ms. (21.4216 H/s)
Kernel run took 79 ms. (21.4188 H/s)
Segmentation fault (core dumped)

What could be the cause of that? Is one of my card faulty of could it be a bug in Zogminer?
Oh yeah, don't mind my directory structure. I fucked that up for real, but I'm glad it's working

Keep up the good work. If there is anything I can do to help, let me know.

EDIT: I checked the temp on both cards. They are both mining, I believe:

Code:

thomas@thomas-B85M-D3H:~/wolf-xmr-miner-master/zcash$ aticonfig --adapter=all --od-gettemperature

Adapter 0 - AMD Radeon R9 200 / HD 7900 Series
            Sensor 0: Temperature - 49.00 C

Adapter 1 - AMD Radeon HD 7900 Series 
            Sensor 0: Temperature - 46.00 C
thomas@thomas-B85M-D3H:~/wolf-xmr-miner-master/zcash$ 

[lpedretti]

It's indeed very cpu intensive, with a dual core athlon x2 5x rx 470 8gb around 34s/s each card, the same setup but changed to a sempron 140 single core reduces it to 24sols/s each

May be hash cpu validity checking?
If that's so, it may be turned off at the expense of some invalid shares in the pool.

Best regards!

opened this one, anybody here can tell me where to change the CL location in the sources?

Built on Slackware-current 64 bit linux(has only mesa, no proprietary AMD driver), but not works:

Code:

./zcash-miner -G

Should OpenCL work with MESA 17.1.2?
