Claymore's ZCash/BTG AMD GPU Miner v12.6 (Windows/Linux)

[GabryRox]

Firstly, big thanks to Claymore for getting this great miner out to everyone!  I know you mentioned that you still expect you can get better rates down the road but I think I am not alone in appreciation for you publishing this version now so we can mine more efficiently than other options currently available!

I have only read about half of this thread so sorry if I am repeating anything here but I did have a few observations and questions that I wanted to post.

- I have 4 MSI RX 470 4GB (strap 1500 mod, overclocked, undervolted) averaging between 40-42 Sols/s each using your miner. This is a vast improvement over the 13 I was getting using nicehash the last few days, so really appreciate the extra sols!

- I noticed that the power draw for this miner is much lower than your ETH Dual Miner.  Even just solo mining ETH my rig was using ~625W at the wall, while your ZEC miner is only using between 400-450W!  This of course increased the profit margin over ETH mining even more, which is great, but I have a question about the power consumption.  Is it just that mining this coin is inherently less power-consuming than ETH?  Or, does the much lower power draw mean that there is still a lot more headroom to work towards increasing Sols/s even more?

- Finally, after running your ZEC miner stably for about an hour this morning, I launched nicehash miner to use only its CPU ZEC mining function. Unfortunately, almost right at launch, it cut the Sols/s rate in your miner by about 25% on each GPU.  Then after about 5 minutes, it crashed my system. Then crashed again after reboot, so I haven't tried it again.  This seems a bit weird to me since I have used other CPU/memory intensive programs like Claymore Crytponote CPU to mine XMR and plotting & optimizing BurstCoin plots on HDDs and neither affected your ETH GPU miner.

Normally, I wouldn't even bother about CPU but this rig has an i7-6800k that was pulling 23 S/s, which equates to more than half of a GPU, so I hate to waste it idly.  Anyone here been able to CPU mine ZEC with NH and GPU with Claymore successfully?

i7 3770 and 1x amd fury almost 11 hours stable now.. -t 6 ..win7 x64, 16.10.3 driver

You're using Nicehash for your ZEC CPU mining?

I get from 80-100 H/s with Genoil.

I can not get this miner to work at all with Suprnova!

Code:

ZecMiner64.exe -zpool zec.suprnova.cc:2142 -zwal <miner.name> -zpsw <password> -allpools 1

This miner seems completely broken and started losing me money.  I get 0 H/s on Suprnova with this miner.

The 7950/7970/280x were always the best mining cards due to their large memory bandwidth.

If it wasn't for the DAG file in ETH they would still hash at 27MH/s.

During the Litecoin days they hashed at 80% of the speed of a 290 and cost only 60% of the price. They were forgotten with ETH mining but are now back and killing RX480s.

the easy answer for the RX480/ 470 owners your cards only have a 256-bit memory bus while the HD 7950/ 7970 & R9 280X have a 384-bit memory bus, so even with the slower memory they still have a greater bandwidth at 1750Mhz they bet  a Rx 480 at a clock of 2500Mhz in total bandwidth.
In addition the color compression, i.e. frame buffer, was also reduced in the Polaris cards it went from 64 to 32, so without the software being written to take advantage of the memory optimization, on the RX series the memory just isn't utilized as efficiently.

Did you set your nicehash miner using -t 6 ? (6 = 6 threads)

Nope... thanks, I will give that a try and see what happens.  Out of curiosity, how exactly would you do that?  I know how to make that kind of change like in a .bat file (such as exists in Claymore's work) but I only see EXE and DLL files in the NHM directory.

what is the hashrate for 7990 alone?

[CoinPro69]

I have around 60-65~ Sol's with my computer.

For now just 1 470 4gb nitro 42-48~ with claymore

and a 6600k 18-19~ with nicehash

running both together stable.

Will get 24 GPU's soon... letz see how it will roll then

I got this error. Try uninstall and install driver again but not working.

[molitar]

This miner is more unstable than genoil.exe. 

It stops mining and stops responding more than genoil. It does not even run for 5 minutes!  So my hashes never go above 58 plus when they should be around 121 H/s.

GPU 0: R9 280x (3GB) 43.x S/s
GPU 1: RX 480   (8GB) 44.x S/s
GPU 2: R9 380x  (4GB) 30.x S/s

i have those and works fine. I tried to mark them on paint but that fucked up the resolution (no idea why). i hope u can see them the txt and bat file.

Please somebody give another link to claymore... google drive is overloaded 

[ryantc]

a big thanks, that's a big speed improvement for me.

BTW, all my cards are pointing to suprnova and it seems fine so far.

now my 7950s are doing 37
two 7970s are doing 41
the other two 7970 may need some tweak as they are only doing 35....

You're using Nicehash for your ZEC CPU mining?

yes. nheqminer_v0.4b version

use the nheqminer.exe github download link at nicehash "getting started" page

nheqminer.exe -l stratum.zcash.nicehash.com:3357 -u zcashwalletaddress -p x -t 6

How many threads were you running using the Nicehash CPU miner? You need to leave some room on the CPU for OS and other programs. With your i7-6800, I would recommend using 9 or 10 threads at most using the -t command line option.

Thanks very much! I can see it fine when zooming in. So... I checked that directory and I do not have that .bat file in it.  Did you just created that yourself and use that to launch nheqminer in a command window (meaning that you not not use the GUI)?  Or, do you create that .bat file, then launch the NHM GUI exe and that will pick up this new command?  Thanks again, I am still learning this stuff

[pwpwpw]

while monitoring nicehash on their site, the miners never seem to be running for more than an hour, is that because of devfee disconnects ? Also I had about one failover disconnect / hour on nicehash, it's not offline so there must be some bug receiving work from their pool.

ZEC: Received unknown response: {"id":null,"method":"client.reconnect","params":[]}

ZEC: Stratum - socket send failed 10053, disconnect

Is this coming from the miner or their pool?

[doktor83]

[sanyok]

I will check it, probably I will release an update in a day.

Linux version ETA?

One day.

Temporarily running Windows, it's a bomb miner!
Hope to run it on Linux soon

THX!

[rockyforever]

I am pretty sure its the pools you guys are using not the miner. I am using flypool and have been running claymore stable since he released it. All the complaints about an unstable miner seemed to be linked to an unstable pool. Please read the forums on zcash to determine which pool is the most stable because its annoying to keep reading these individuals problems......
