EWBF's CUDA Zcash miner

[crypper]

Hello to everyone,

I got an asus strix 1070, msi gaming x 1070 and zotac 1070ti amp working on the same rig. From time to time I'm getting this weird error when I'm starting a EWBF miner. Miner starts normally can find CUDA 0,1 and 2 devices. But when it comes down to solver it can initialize only Solver 1 and 2 not 0 which in my case zotac 1070ti. Then it is a BSOD witch nvlddmkm.sys error with header VIDEO_TDR_FAILURE. Cards are underclocked so there are no power issues at most with a 700 W aerocool PSU.  

Looks like driver or overclocks problems. I would start with DDU, reinstall driver with only one problematic card in the miner (1070ti). When it works move to other cards.

I removed and reinstalled all drivers. Changed all risers with new ones. I run each one of the GPUs one by one with both overclocking and without it. They work ok. But when I try to make them work together they fail again. Still got no solution. Could this be power related? Got a 700W aerocool psu and kill-a-wat is at 450 W max before it raises an arror. I got the same PSU in another rig with 3 strix 1070 OC and they do fine. I'll switch PSU's and check if this one is defective. And I'm still open to more help.

Thanks.

Well, if you have another rig, then just replace one of 1070 with a problematic 1070ti in that rig and see. It could be power issue as well, but 700W should be plenty for 3x1070 (unless the power supply is faulty). Some people complained about power consumption spikes during initialisation of the cards. Try lower intensity settings. Alternatively try  DSTM's miner, I believe it initialises the cards one by one.

Well he did a great job. So he deserves it.
Great job because: he has not updated the miners in months and it run faultless with any cards in any rigs on any OS. The number of complaints is minuscule (ignore those noobs who cannot set it up properly). And now consider claymores miner: yes it's full of features, but the amount of bugs and complaints is enormous. He released 4 updates in just a couple of weeks; and they were not speed improvements but bugs fixes. So I prefer something simple but solid (I don't need all those features claymore offers).  EWBF runs solid for weeks/months (I think I only restart rigs when I decided to do so, occasionally). TBH EWBF is the best miner I ever used.

Having said all, he should come back and support us. He gets tons of money and dont support us which is a shame.
Also...I see him active on the forums, but he just seems to be avoiding us

wow thanks for this interesting share, EWBF makes 800k+ USD / month on dev fees; gives a lot of clues as to overall miners in ZCASH, and obviously how insanely profitable writing a competitive miner program is !!

[Biodom]

What driver is the most stable driver?

Ubuntu Linux 16.04 with the recent kernel, EWBF 0.3.4, nvidia 375= working for 3-4 wks (or more) at the time with no interruption.

As it seems that Terraman didn't support EWBF dev anymore.

And apparently he's quite rich now (in zcash at least)...

You can do a MITM attack on our own rig (no scam as you do it yourself)...

This MITM will also help you to verify that the announced 2%fee (or custom one from --fee argument) is never respected...

Enjoy!

just out of curiousity, if the 2% fee or custom fee arguments are never respected, what is the effective fee we are paying when we just use EWBF regularly (ie when we don't use the suggested MITM solution) ?.. I suspect the MITM would bring its own stability problems into the mix, although I've never tried that as a workaround before. We know for a fact that for example Claymore's effective fees are also higher than the alleged 2 %, or the miner ends up mining less than an effective 98% because of all the interruptions...

Indeed, like Claymore the fees are almost always over the one announced.

i'm new with this.. just came from eth , Which is better with it
higher memory speed or gpu core speed ?

[QuintLeo]

Depends on the model of GPU and sometimes the specific card.

just a little zcash benchmarky site that might help show things to under and over I'll leave here. some entries are a little silly in that it's not single card hashrates but might help nonetheless.

1070's and 1060's

1070:
Core: +100
Mem: +500
Raising core and mem further may or may not increase hashrate. Core +200, mem +800 is probably the limit for most cards. Just try it with your cards and find the optimum settings. Power should usually be 65-70%, but that again depends on your cards.

Don't bother, --devfee 0 will have the very same result as MITM. Can't You recognize trolls repeating same things without single screenshot confirming?
BTW Looking in someone else pocket is bad habit. Speaking about is even worse. Can't help, but some things person is learning up to 7 years...

bro your English sounds a bit weird, I don't know what you are objecting to, but the discussion was about profitability and efficiency, not fairy tales of pseudo morality from 17th century...

no it doesn't do the same as mitm, in windows that --devfee 0 is broke its something within windows has to do with how windows looks at it. in Linux though the --devfee 0 DOES work correctly as its supposed too, not to mention everyone knows the miners do take a little more than there advertised 2 percent, claymores miner does, so pretty safe to assume other miner programs do as well

Hi.
I just registered to confirm something.
I just set --fee to 60, that should mean 60%, and I got many messages like this
INFO 03:54:46: GPU0 DevFee Accepted share

however when set to 0, I dont see any of these.

Does this mean, with --fee 0, there are no fees, as we dont see any of these "INFO 03:54:46: GPU0 DevFee Accepted share" ? Not sure...


I saw a post once where they suggested to use 0.1 (0.1%) to see some difference.I also saw a post saying that if that is set to 0, then it will just generate some random number instead of 0. Idk if true, but like I said I dont see any "INFO 03:54:46: GPU0 DevFee Accepted share" with fee 0 but on the other side, idk if this is a good enough proof that proves that there are no fees.... 

(I am using Windows 10 and 0.3.4b miner)

Read my post above and tell me what u think
