New Faster EWBF CUDA Zcash Miner for Nvidia GPUs

7 Dec


There is a new miner for Nvidia CUDA GPUs available for mining Zcash (ZEC) promising a slightly faster hashrate than the currently fastest implementation of the NiceHash EQM Zcash NVIDIA miner. The most important thing about this new miner is that it is not limited to only mining on NiceHash, so even with the same speed it is still a nice thing to have as it supports Stratum mining on other mining pools besides NiceHash (it does seem to support NiceHash’s Extranonce Subscribe as well). According to the author of the miner it is designed for Nvidia Pascal GPUs, but should work on older Compute 3.0 or higher Nvidia GPUs with at least 1 GB of video memory. Do note that the miner is not open source and there is only a Windows 64-bit binary release available at the moment, it does not seem to be based on other popular codebase and is not being reported as malicious software by antivirus products. You might still want to have something in mind as the user that posted it on Bitcointalk is a new account and not an established miner developer, even though it seems that the miner does work pretty well.

The EWBF CUDA Zcash Miner has a built-in developer fee that is set at 2%, meaning that every 10 minutes the software will switch to a different pool and mine for the developer some shares and then get back to mining for you. The author of the software claims speeds of about 250 H/s for Nvidia GTX 1070 while the NiceHash EQM miner does currently about 220 H/s on the same GPU. Our quick tests showed a hashrate of about 235-240 H/s average (up to 250 H/s) on stock GTX 1070, so still slightly faster, but not as much as you may want it to… then there is the dev fee as well and it seems that we are seeing somewhat more rejects than, especially when switching to mine for the dev fee. So while this may be an interesting alternative for users willing to mine outside of NiceHash, the actual performance that you may get poolside may not be much different than with what is currently the fastest implementation from NiceHash (taking into account the dev fee and the rejected shares)…

750Ti = 52
GTX960 = 106
GTX970 = 177

no reject with coinmine at all=)works on 660 ti – 46-47 sols. 1070 – 275-280 sols OC.and it’s workin with pools!much more profit to come=)

Best pool works for me on no rejects full speed

GTX 1060 = 175

I have changed my graphic card with Radeon and now again Nvidia is rising…. :'(. No hope for all of this….

Hate to make it worse but new NHM EQ miner gets 336 SOL/sec on overclocked 1070 :)

asus GTX 1080- 267 sol

Does this look normal for the card i have?

I would love to buy a new Nvidia GTX1050 or Radeon RX460 ?
Please can somebody suggest?

Do i have hope in mining with those cards for a few dollars a week?
if it was say 5 dollars a week? not even sure if it is worth it .

Pretty weird that people get only 200-240 sol/s, because I get 400-500 (sometimes peaking at 700) with my Asus Strix 1070)

What do you think?

I’ve done a search here and no one is talking about Bminer a new Equihash miner released last month.

I started with EBWF then I discovered DSTM which was the tits with the higher hashrate but it was fairly unstable if I tried to adjust the vid cards through MSI AB giving me hard freezes or bsods. Sometimes they happened a short while after I walked away after adjusting a setting to give it time to settle. Sometimes hours later.

I saw this post:

and tried it out.

Using the exact same stable msi AB settings I dialed in with DSTM, I tried it out for 24 hours and didn’t get a single crash and rejected shares were single digits out of almost 3k shares submitted and my overall hashrate went up +60 sol/s. I’ve also noticed it doesn’t mind when I’m tuning the graphics cards while active and have never gotten a bsod or frozen pc in days now. Cherry on top is that I personally like the telemetry screen which is a bit nicer to monitor over dstm’s. Devfee is the standard 2% same as all the others.

Just wanted to share because I know we’re all trying to find that razor’s edge of performance in our rigs.

I set –intensity value be 32(allowed value is 1-64),so i think my gpu load should be 50%,but it is still 100%.I don’t know why. And i want to reduce my gpu load,what should i do,thank you.
