On my linux rig with 12 cards i'm getting a lot of "Duplicate share" messages, on windows i dont see this message. Is this normal? Question for the dev.

Yeah, me too. At least 30% of my shares are duplicates, that’s why i haven’t switched from dstm. I also run 12 GTX 1070 but on Windows, haven’t tried it in Linux.

For 30min mining almost half of the shares are rejected, this is no go for 12 cards rigs back to the old miner. Hope the dev will address this issue.

hmm.. I tested it extensively on 6 card mining rigs and did not encounter any issues. I don't have a 12 card rig right now but I'm interested in looking into it deeper.

As a work around can you please try run two bminer processes which different device IDs? For examples,


bminer -devices 0,1,2,3,4,5
bminer -devices 6,7,8,9,10,11


Please let me know the results. Thanks.

This does seems to work no ""Duplicate share" messages, probably there is a threshold above which the threads syncing is getting messed up.

Can someone help me with my miner.bat file

@echo OFF
SET ADDRESS=mywalletaddress
SET USERNAME=worker1
SET POOL=us1-zcash.flypool.org:3333
SET SCHEME=stratum
START "Bminer: When Crypto-mining Made Fast" bminer.exe -devices 0 -uri %SCHEME%://%USERNAME%@%POOL% -api 127.0.0.1:1880
Error: End of file. Nounce


EDIT: I figured it out. Link below for sample miner.bat configuration.
https://www.bminer.me/examples/

Side note: anyway to find out average hashrate for gpu device over time please.
Thanks bminer

Did some initial testing on my 1080 ti Aorus in the gaming rig - and not real impressed.

 +100 core +100 memory same as I use on EBWF

 60% (150 watt) and 70% (175 watt) TDP settings - EVENTUALLY settled in at same-to-1% higher than EBWF, but took 2+ minutes to get there.
 80% (200 watt) setting - eventually settled in at a hair LESS than EBWF after 5ish minutes of waiting for it to get there.
 90% (225 watt) setting - never got above 740 where EBWF gives 760 and took 2 mins to get to the 740 figure which didn't improve in the 5ish mins after that I waited on it.

 CPU usage showed some serious spikes on a Ryzen 1700 - not enough to be a problem on THAT CPU but I can see it causing issues on low-end dual-cores running multiple cards.

 Even where the hashrate was higher, it wasn't ENOUGH higher to make up for EBWF fee configurability.

 I'll do some testing later on lower cards, especially the 1070 ti that is my current "go-to" option for ZEC mining.

Can't believe how many ungrateful persons are there. Man made a free miner (with a fee, but it's free) and you are complaining like he owns you something.
No miner is perfect when it comes out, those things always need testing and polishing. I don't doubt that CPU usage will be fixed in some of the next versions.
Good job dev.

 fee to use = NOT FREE.

 Unlike EBWF where the fee is by default but can be configured to be lower or zero.

1070's max power isn't 250W, not sure where you got that from. It's 150W. Thus 65% would make it run at 98W. Yours runs at 161. You'd never be able to run it at above 180W, let alone 250.

250W is 1080Ti's max power.

Like it says on the top of the specifications in your link, the 150 W power limit is for the reference cards. The Zotac AMP! Extreme 1070 is a dual 8-pin card with a max power of 250 W.

 Quite a few 1070 models have a default 180 watt TDP.
 MSI makes at least 1 and I think 2 with a 240 watt TDP in their "Gaming" series.

 This is WHY I keep trying to tell folks "specify watts, NOT PERCENT" on TDP numbers as % means NOTHING unless you specify the specific card model and even THEN it's confusing.

Probably a noob easy question but after looking for 30 minutes I didn't find the answer so here it is. How do I append the -polling=true in the command line? AKA how do I open the command line and then append it. Whenever I click the bat command file it just starts mining but I can't type anything.

Please don't laugh. Everyone started at some point Wink

Right click on the .bat file and select "Edit" from the dropdown list.

Getting message temperature 86c, slowing down for 2 seconds.

Oh, so they shifted the power limit for it... That makes mentioning the setting in percentage misleading. That being said, the card will throttle down hard if pushed above 180W anyway.

In either case I was originally wondering about being able to reach >500 sol/s at 3.4 sol/J; now that I know it's not a sustained figure it doesn't matter. I was thinking perhaps your card was really well-manufactured or you won the silicon lottery big time with it, but ~510 sol/s at 162W is something achievable on mine as well (~508 at 158 here).

250W is the 1080Ti's default power limit. Max power limit you can set to is 330W or 360W if it has a 280W default limit.

Ah, that explains it: your power limit isn't actually in effect, which is demonstrated by the card consuming up to 161W, or 107% (not 65%), performing at 3.15 sol/J. Those are expected values for a well-made 1070. I thought the 503 sol/s at 147W was a sustained figure, which it doesn't appear to be. Got my hopes up for a second there. Cheesy

The 65% power limit is in effect. The max power is 250 W, 250 x 0.65 = 162.5 W. As long as the extra hash is profitable the extra wattage is irrelevant.

Can confirm that Slushpool works now. On my GTX 1070 with 8960 MHz mem clock, 105% power limit, and CPU polling disabled in the miner, I'm getting about 508.5 sol/s (3.22 sol/J), or ~6 sol/s more than on the DSTM miner on average. (Note that this setup is optimized for maximum profit rather than maximum power efficiency because power is very cheap here.) I also enjoy the fact that it keeps desktop applications sufficiently responsive by default without dropping too much performance (I see a ~4% drop when e.g. watching a YouTube video, which is perfectly acceptable) and without having to manually tune intensity settings. Good job there!

Although by a small margin, this is, indeed, the fastest miner around. At least until DSTM turns off the dev fee. :p

Could any 1080 Ti owners test this miner on their highest stable clocks (without voltmod) and report the sol/s values they're getting? I'm interested in investment opportunities. If my estimates are correct, it should be possible to push some 810..825 sol/s with this miner.

Awesome update. On 3.0 I'm getting 1080-1090 Sol/s with a GTX 1080 and 1070 @ ~300 W! The high CPU usage is now gone with ~30% usage on a G1840.
Is this with CPU polling off? What are your 1070 clocks? I don't think I've ever managed to go above 500 at 98% power limit (which I assume is your setting).

Zotac Amp! Extreme GTX 1070. Core +100 MHz, Memory, +500 MHz, Power Limit 65%, CPU polling off. Running stable almost 2 days. With EWBF 0.34b I get ~460 H/s and with DSTM v0.5.7 ~495 H/s with the same settings.

"only" for all 5x 1070 together

with the 2% fee, EWBF is still more profitable for me
You might need to check your math. In order for a 2% fee to be a net loss compared to 100 less sol/s your setup must output over 4900 sol/s, which is outright impossible even if you have five 1080 Tis.

More realistically, I'd expect each of your five 1070s to work at around 480 sol/s. That's 5×480=2400 sol/s, or 2400+100=2500 sol/s with bminer. Deducting 2% dev fee, that's 2500×0.98=2450, which is 50 sol/s more than EWBF.

For me it's only 100 Sol/s more than EWBF
"ONLY"  Grin for what GPU - 1080ti?
