EWBF's CUDA Zcash miner

[Temporel]

Which manufacturer and which driver versions are you using - Windows 10, right?

I have a rig of  6x Gigabyte Windforce GTX 1070s overclocked to +35 Core Voltage, 88% power limit, +137 core clock and +610 memory and getting the following:



That's on Windows 10 64 bit with GeForce driver 22.21.13.8494 from 7/18/2017

What's this display?

the built in api from ewbf.

add "--api 127.0.0.1:42000" to your batch file and use your browser to view it

Over the last few days I keep getting gpu 0 has stopped and my small rig just goes to sleep. Is there any way to loop the miner so it starts back up also happens when it loses connection to server.

 Indicates you likely are trying to overclock that card too hard, or pushing the power supply too hard - EBWF will try to restart on it's own, at least in the most recent version, but it has limits on the sort of issues it can handle.


 The base Aorus 1080 ti can probably get to 800 sol/sec without undervolting if you turn the TDP up to 300 watts or so (120% in Afterburner) with +100 core +100 mem clocks - I see 780 more or less at 250 watt stock TDP with those clock settings.

 I suspect any of the "3 slot" well-cooled 1080ti models will be in the same ballpark.

I found out that you're better to go with a medium overclock instead of going to the max. I don't recommend to use 120% electricity for a longer period of time.
For my 1070, I found out that 70% electricity with +150 core and +400 mem clock is way more stable and nearly as fast as a +200 core and +600 mem clock.
70% electricity gives me a return of about 3.5 sol/w and 100% td p is about 2.5 sol/w.

i agree with not turning the TDP up as it results to a very low sol/w. Also, your card's lifespan may be reduced as its on that state 24/7. On one strix 1080ti oc, I'm getting 690-720sols at 75% tdp, +105 core, +130 mem. temps stable at around 55degC.

Why has EWBF miner doubled its DevFee on Flypool? This occurred when Flypool cut earned shares in half on Sept 28th, DevFee shares did NOT halve like earned shares (DevFee is twice what it was on Flypool). I expect this is a bug due to how you implement the following:

Why does EWBF miner strongly scale DevFee with difficulty? Statistically this is not a 2% DevFee and is realistically very much higher. See: https://forum.z.cash/t/ewbf-dev-fee-almost-doubled-1-9-to-3-6-average/22460/4

I am all for DevFee's, you should be paid for your work. However, I have an issue with misrepresenting the real DevFee. That is dishonest, makes me not trust you, and want to switch to other miner software. Just tell everyone what DevFee is, and let them decide.

The dev fee shares are probably of a lower difficulty than the shares for your account.

You can also disable the fee without any penalties.

How?

disgusting work!
the most problematic miner.

never had a single problem with this miner. Both Linux and Windows release can mine for weeks with no issue.

After over 5 months using this miner, I have to disagree. What's wrong with it, in your opinion?

[Nippy-ua]

after stopping the miner, the system begins to terribly buggy.

Really, I'm a bit surprised, you disgusted a miner working greatly to us and stable mining for a months.

There you go, don't blame the miner, seems your system that is problematic indeed. anyways, you are free not to use it, if you deem buggy

I'm mining zec on flypool,.. but it looks very down.  https://cryptowat.ch/
Any suggestions for what you guys' are mining?

thx

For me nanopool was giving the best result 0.0105 ZEC every 8:30 - 9 hours average with 2 gtx 1080ti and one 1070 g1 rev1, but I strongly recommend zcoin at least for me is much much profitable

https://zec.nanopool.org/  ?

I'll check it out and see.  Thanks

Yes that is it

Hello guys i have very frustraiting problem ..
On half of my rigs gpu 0 is mining with 50sols less then the rest .
I did try everything , make the mobo integrated gpu as main does not help i have installet chipset drivera for mobo
Nothing .... any clue what it may be ?
I am using palit sjtr , asus rog strix , zotac amp extrm all 1070 rigs and all havng the same issue Gpu 0 low hash with 50 sols less , also gpu 0 consummg less electricity bit thats not the point .
Any help will be appreciated !
Thanks in advance

I think that's normal.
I also had that with 6 x gpu

even if you have access via vnc, you will also lose sol/s
but to your real problem, I can only say that it's apparently normal.

I think someone has explained this in detail before.

regards

That isn't normal,.. as I just had this issue today for the first time.  My 4th card was only mining at 70% 
To fix it,. I reset msi afterburner to defaults, shut down... checked connections throughout.. rebooted,.. and now it's running all cards properly.  (Also I made sure zcash4win was sync'd with the website,.. before running my ewbf .bat)

Currently mining (Nvidia cards) VTC, ZEN, Mona and ZEC

And those who believe in fairy tales are currently mining Zcoin, BitcoinZ and other obscure coins

i've set one of my rigs to mine BitcoinZ, but I don't think I believe in fairy tales.. But the possibility of it becoming a whale interest in the (near) future does excite me!

Im not saying you wont make money, but the dev is an amateur and he clearly doesnt know what to do next. There is nothing interesting about this coin like 98% of altcoins.

yeah it's actually very difficult to root out that 2% in that case.
but i think even amateurs can bring out some good stuff every now and then.

dstm's ZCash miner faster by 8 % !!!!  https://bitcointalk.org/index.php?topic=2021765.500

[oualid]

for me with Gtx 1070 armor i get 470~sols

[Sy_]

1080 gets 49x

[flip4flop]

Just started mining today on flypool with 4x 1070 MSI Gaming at around 1853 sols.  So far it seems to be working great!

[Plumbus]

How do I exit immediately if the connection to the pool fails? "--eexit 3" takes a long time to exit

[induktor]

Hi
Anyone tested it with a 1080Ti ?
it looks quite unstable, hashrate jumps up and down all the time, it is hard to find the best efficiency values

thanks

Another question.. (not mine)  what are all these additions?.. Are they for the 'config' file?  Looks like this person added it to his .bat file.

setx GPU_FORCE_64IT_PTR 1
setx GPU_MAX_HEAP_SIZE 100
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_SINGLE_ALLOC_PERCENT 100
miner  --server eu1-zcash.flypool.org --port 333 --user 48utjduvljnaluiornhjdgalkbhvjlaiubg.009 --pass x

THOSE "SETX" ENVIRONMENTAL SETTINGS ARE AMD SPECIFIC--

Some people erroneously think that they are required for nVidia cards.  They are not.         --scryptr
