EWBF's CUDA Zcash miner

[webdelver]

Funny, I've got the opposite, I dropped my mem clock by almost 150 on each card +40 core, +25% power and I am consistently getting around 780 sol/s per card
- 2x Aorus GTX 1080ti xtreme edition
- Using GFE, AfterBurner doesn't let me adjust it properly

What is GFE?

He is probably talking about Geforce Experience, the addon program (that I don't recommend). Best and most simply OC tool to use is Nvidia Inspector by Orbmu2k. Portable and does not clutter up the system.

 I make a point of NEVER installing Geforce Experience. Horrid excuse for a program, even more worthless than Wattman (and I have no use for Wattman)....

Afterburner might be a solution to tweak a setting or 2. I've gotten mine setup for my 980 ti, added 150 mhz on the core, not on mem because it does nothing in my case. Result 550 to 600 sol/s. adding more voltages or mhz doest do much either. Key might be that i keep it cooled very well. which results in good card performance.

We've been on Version 0.3.4b for so long now I wonder if we'll ever get a newer more efficient version?

What is GFE?

My mistake, I meant gigabyte xtreme gaming engine.  Which, in my opinion is not the best, but I have found it works for me.

I had 2 of those myself - the overclocking was linked to the power level, at least for mining.  I ran mine at 133% power, at which point the core was ticking at 2ghz and the memory I had overclocked to about 12.5ghz stable.  I didn't overclock the core to achieve that boost, it did it automatically.  I picked 133% because any higher than that didn't give any faster hashrate, only burned more power.  Seems the EWBF miner maxed out at about 125% TDP, but occasionally would hit the power limiter if the power level was set to that exact level so boosting it to 133% gave me 780-800sol/s. 

Without the power boost they would get about 740-750, so I ended up dropping it to normal levels just to save power cause the extra sols weren't substantial enough to warrant the higher bill.  But I was never able to overclock the core by more than +50 at any power level, I guess because gigabyte binned the chips and overclocked them in the hardware so pushing them more destabilized the system.  Memory I could overclock to 12.75ghz pretty stably, but ran mostly at 12.5ghz since that seemed to be the peak of gains for mining.

When I start up the miner, one of my cards says that it isn't selected. How do you select it?

what is in your startup .bat?

what type of card is the one that's not starting up?

[parker423]

The miner stops working after a few hours.

There comes a red line in the miner.

[nUm81]

try to reduce your overclocking.  If that doesn't help set up the .bat file to restart when the card fails.

[parker423]

How to add restart?

[nUm81]

.bat needs to contain some sort of loop

:start
timeout 30
miner --config miner.cfg --api
ping 127.0.0.1 > nul
goto start

and make sure you set the -eexit 1 in either the .bat or .cfg file to trigger the restart when the miner stops.

[parker423]

miner --server zdash.suprnova.cc --user xxxx --pass xxxx --port 4048

:start
timeout 30
miner --config miner.cfg --api
ping 127.0.0.1 > nul
goto start


like this text in the bat ?

[nUm81]

:start
timeout 30
miner --server zdash.suprnova.cc --user xxxx --pass xxxx --port 4048 --eexit 1
ping 127.0.0.1 > nul
goto start

Like that if you don't run the config file

I made a small GUI for this miner (open source) that is able to plot the mining performance and restart miner if necessary. The script and windows binary can be found at: https://github.com/K4P11/GUI-for-EWBF GUI in operation shown in picture: https://github.com/K4P11/GUI-for-EWBF/blob/master/GUI.png

looking very good, thx

My issue:
I had two rigs with 1060.
Rig1 - 2 x 1060 6gb - gave me 270sols/card (at my settings)
Rig2 - 2 x 1060 3gb - gave me 250sols/card

Now I switched all 4 cards into one rig, I'm using the same clock/power draw setting as before but getting less Sols
Rig1 - 250 sols/card
Rig2 - 235 sols/card

Any idea why is that?

Before and now running win7 x64.

[Gaglam]

Will there be any update again?
Great miner btw

Have you changed from being in 16x PCIE slots to 1x PCIE risers?  I did notice a small decrease in hash from testing a 1080ti in the 16x vs running on the 1x riser.

Yes I did.
Didn't know this has such an impact on hash rate.

I'll have to try raising the power limit to 133%, I have noticed very similar results for mine and would like to make the most out of these cards since that is all I use them for.

[nUm81]

I think from memory that I lost about 50 sol/s moving the 1080ti from the 16x to the 1x riser.

useless for mining but the Shadow recorder is really great for gamers who need it.
