EWBF's CUDA Zcash miner

[Arnold1990]

Hi guys i'm using EWBFS and i have 6 gpu in my rig.
the problem is when i use 5 gpu every thing is good but when i turned on the 6th gpu one of the gpu is shutting down and that gpu is not working untill reinstall the gpu driver. so does anyone know what is the problem?

What's your GPU types, OS, RAM, PSU ratings ensure that it could handle the 6th GPU.

check you clocks also, if the GPU is not identical, higher clocks may not be coped up to others.

my gpu is
2* Geforce GTX 1060 windforce Gigabyte
2* Geforce GTX 1060 6gt ocv2 MSI
1* Geforce GTX 1080 msi Gaming X
1* Geforce GTX 1070 msi Armour

my os
chekced on ubuntu 17
windows 10

Ram
4gb ddr4

PSU
1- Thermaltake smart se 730
2-Coolermaster 700 lite

Motherboard
Asrock h110 pro btc

So here is the first part of report, i have run EWBF with --fee 0 for ~28 hrs. on 6x1080 rig. Little exploanation:

On the right there is flypool stats with highlightet 24 hrs window start, below is miner screen at earlyest time i was able to scroll to (2018-01-28 ~11:00)
On the left same flypool but end of test highlighted + screen from miner at test end.

Dont look at miner heading it is coming from bat file naming istance, so i just forgot to change to flypool.

So even with --fee 0 real hashrate is ~2% less then reported.

Now DSTM will run for good amount of time and i check it somwhere on saturday.

It is big screen actually, so i leave full link https://imageking.eu/images/ewbfcompar.png

BTW --fee 0 or --fee 0.0 switch is working? I mean --fee 0 could not work? Or it is working but miner trottling de to --fee 0 is used?

I don't understand what You are trying to convince all of us here. You spent some time stitching 4 different screenshots. --fee 0 is working for me and there is no single devfee share with it. It is not "throttling" because GPU usage curves in Afterburner are same with or without switch. I believe You will find that with zm miner You have time window with 2% higher pool average hashrate than reported by miner.

I concur with chup. I'm runing two rigs, one on Windows 10 and the other on Ubuntu 16.04. I'm using "--fee 0.0" on both and I'm watching TCP connections as well as I've verified with the EWBM MITM that I'm not submitting any dev shares. I wonder if folks who are reporting 10% or some other amount and are using --fee 0.0 (or --fee 0) got a modded version? Make sure you check signatures! I don't know how else to explain these problems - but it's working as documented for me on both Win 10 and Ubuntu 16.04.

Yesterday I did my own test on each OS for 1000 shares - both Windows and Linux only submitted 1% of my shares for devfee (not 2%).

ALL OF THAT SAID: If the dev's do come back and start working on and improving the miners - I do pledge to pay FULL devfee royalties - but since both developers are long gone - I don't see the need to keep paying royalties "just cuz". They gave me the option to use --fee 0.0 - so I'm exercising that option for now.

That being said, I did briefly consider running the MITM to get the extra 2% - but it doesn't do connection failover to different servers - AND - it goes against the spirit of what the developers want - so for now I'll stick w/ using miner.cfg and --fee 0.0.

Ok so playing around a bit with EWBF again. Was using this, went to another one and now looking at it again.  BUT having an issue.

On my 1060 6GB card 0.3.4b version is NOT as hard on the GPU as the other miner I've been using.  Mind you the GPU is pegged but on the core clocks are lower.   That being said... is there a line command to make sure its utilizing it properly?  My clocks are roughly 25-50Mhz slower on the core vs the other one I've been using and drops my SOL's roughly 15-18 Sol/sec.  

This is what I'm using to kick it off.
miner --server us1-zcash.flypool.org --port 3333 --user XXXX --pass x --pec --fee 0.0

Edit Added info... out of MSI Afterburner
GPU usage = 100% (Same across both miners)
GPU FB usage = 74-75% vs 79-80% higher on the other miner! (Note FB = Frame Buffer)
GPU Core Clock = 1823Mhz average vs 1860Mhz average
Memory = 4200Mhz (Same across both miners)
GPU Power = 78-81% (Same across both miners) Set for 80% power limit

Been curious why another miner was getting better results constantly and now this would make sense why is that its not clocking the GPU as high yet same power/temps/clocking results for the switch between them.

Hello ! (sorry for the bad english)  

Can you tell me, or explain ?

Has there been an increase in the frequency of "devfee" ?

I actually advocated EWBF in DSTM thread, but sticking with DSTM now Test ended with average 3049 EWBF vs 3099 DSTM. 50 free hashes? Sounds good for me... --fee 0 didn't helped EWBF. And at least in my case i still see 2% less shares then reported by miner. And even some of tou say you see 1% it still does not save EFBW.

And this is GDDR5X cards witch presumably should have worked better on EFBW.

P.S. I am not related to DSTM or EFBW in any way, long time used both but recent discussion in DSTM thread pushed me to do a test myself. Believe me or not, this was exactly same machiene of 6x1080 (non ti) not tweaked in any way for one or another miner, and it was not even restarted during test period.

Has this project been abandoned? The OP and miner have not been updated in over 13 months. Last release of the program was December 07, 2016.

Where do you see that --fee 0 doesnt help ? There several posts on the forums here proving that it stops the shares.
Any proofs that it doesnt ?

Screen:

depends on difficulty. should still be 2%.

use --fee 0 and your fee will be 0%

[Justbecause]

Has someone done some test on the most profitable mining pool for zclassic?

[MonkeyShuttle]

How often should you see devfee accepted share?  I went through my miner and it seems its been just about every two or so.  For the whole time its been mining.  I dont mine paying to play but not sure how this adds up to 2% fees.

why does it bother you? If you are using the miner downloaded from the first page of this thread - then it's legit. Don't count dev's money. Just count your own revenues.

[shivgre]

I am seeing a lot of dev fee, in fact every 8 or 5 minutes it mines for 30 seconds or more. Does that count to 2%. Cheater, I know you  have developed this but why cheating by saying 2% fee when its more like 20% or even more.

I will try using this option though :

--fee 0

+1 for making me familiar with HUSH mining, but you should state your fees clearly to be honest.

On top of your groundless accusations (otherwise provide evidence: screenshots, logs), you are not particularly good in math. 30 sec every 5 min is not any close to "like 20% or even more".
Considering that is your first post I suggest you make it your last one on this forum.

Groundless accusation lol, are you mad or are you the developer? I wasn't sitting with a calculator to waste my time, I meant its more then 2%. Mining fee of 2 % = 72 seconds of dev fee mining in an hour, but I was seeing it doing it too frequently like every 5 minutes or so it mined for dev fee for 30 seconds. Dev fee mining is done continuously as I have used claymore ETH miner which does mine for dev fee but at 1% for 36 seconds / hour only.

I only registered here so that I can inform others.

Also after running this miner with --fee 0 option it crashed after 10 minutes and failed to restart automatically.

[geo25]

can i mine with cuda miner zclassic?

[Wotan Wipeout]

yes

[geo25]

do you know what i have to change in bat file for suprnova?

[geo25]

ok i done it. does anyone know if 1520 sols is good for 2 1080 ti or goes better?

[NoOneLt]

Guys ining ZCL what do you think about this? Initiative https://fund.zclassic.org/

[Sam San]

ok i done it. does anyone know if 1520 sols is good for 2 1080 ti or goes better?

strive to achieve 800 sols on the GPU, but it depends on the manufacturer and the OS settings.
