EWBF's CUDA Zcash miner

[Psynthax]

Anyone had an issue where when you close the miner system would lag for few seconds and the miner would shut down, but when you start it again or any application that requires GPU windows notifies me that "Application has been blocked from accessing Graphics hardware" ?

I presume it has to do something with the drivers or what? Its the newest ones but all other versions behave the same.. 

Any fixes for this issue? ..since I am using this machine as my daily driver and I would like to be able to quit mining when I need the machine and continue when I dont without restarting, since restart fixes it until I quit the miner again.. very annoying..  Thanks

I fixed a similar issue by reverting to stock clocks first before shutting down the miner.

Is it true memory overclocking doesn't impact the hash performance?
Unlike to ETH mining where mem OC do the work.

What is the best OC values with 1060s?

 ZEC is a lot less memory-dependent than ETH is, overclocking RAM has very little or no effect on sol/s - depending on the specific card.

Overclocking my GTX 1070 above 200 core clock makes the GPU crash on Zcash. I've seen similar mentions about this on this topic. Perhaps it could be stickied for new miners.

Are there any good combinations of OS and driver version for 1080ti for EWBF?

 That will vary depending a lot on the model of the card, and somewhat on the specific card and the cooling setup FOR that card and the rig it's in.

Hello, I'm noob with overclocking. I have a 6 GPU rig with GTX1060, out of the box they are doing 280 Sol/s (average) 72C (average) with 115W (average), not sure if this is good or below par.
Can anyone share your overclock settings especially on GTX1060?

Thank you very much, it seems this fixed my issue.. will test more..

Hi all,

Running this miner version 0.3.4b on Windows 10 family 64-bit.

Motherboard is ASUS PRIME Z270-P.

GPU's are all Gigabyte GTX 1070 WF OC edition.

For some reason, GPU0 runs slower than the others GPUs most of the time.

I actually have two exact same rigs with the exact same hardware, 5 cards in each one, and GPU1-4 are running at about the same speed (roughly 435 Sol/s each) on both rigs, but GPU0 misbehaves.  Sometimes I get 350 Sol/s, sometimes 150.  Sometimes "solver 2" is selected and it drops under 100 Sol/s.

The problem occurs on both rigs.

Power supply is 1200w.  Rig drains about 950w out of it.

It actually also happens with 2 cards installed.   Doesn't happen with 3 cards.  Didn't test with 4.  Did test with 6 but rig became unstable (I suspect not enough power supply).


I did try to switch cards around.  Didn't help.

Tried PCIe Gen1 or Gen2.  Didn't change anything.

Reinstalled the drivers 40,000 times.

Any ideas?  This is quite frustrating.

Oh and the mobo bios is updated.

Have you resolved this issue? First, disable motherboard graphics display in device manager. Next, don't use any display on your GPU's once you've setup your system and having it running. Login with Remote Desktop and start your miner. Close Remote Desktop and let the miner run for a few minutes. Now, reconnect with Remote Desktop and immediately scroll up through the miner console window and check the hashrates that were reported when you had no display connection at all. In other words, running a display and even running Remote Desktop will slow down GPU #0.

If GPU #0 still runs too slow, switch that card with another card in your system and try the test again. If the problem stays with the same motherboard PCIe slot, then swap/replace the riser card and cables and power cables used on GPU #0 and test again. If the problem still persists you may have a bad PCIe slot on your motherboard. I use ASUS PRIME Z270-AR motherboards and had a bad PCIe slot on one of them. No matter what I did, everything ran poorly in that particular PCIe slot. MSI Afterburner would show terrible looking power and core clock plots. I returned the motherboard and got a new one and everything worked perfectly.

Good luck!

hi everybody, and  thanks a lot EWBF_ for the best miner

I found several issues on ubuntu 16_04, nvidia-drivers version 384.47, 0.3.4b


1) miner starts with such combination --pec --log 2 --eexit 3 --api 192.168.0.204:1070 --logfile /opt/miner/ewbf/miner.log
looks like  --eexit 3 is not working. Miner always tries to restart in case of any errors and it takes about 5 min, but sometimes it start working with 0 hash rates  for hours.

2) Every time when miners restarts "ERROR: Api bind error" occurs.  "netstat -l | grep 1070" show no listen host\port during restart.
3-5 restarts or stop|wait|start can help.


miner starts as a service.
[Unit]

Can anybody confirm the issues?

Hey guys

Running 0.3.4b on Win10 64bit
6x EVGA GTX 1070 FTW
Getting 450-470sol/s  total avg 2700sol/s
Temp 66-71C
Core clock +0
Mem clock +585
Power limit 75%

So far so good 



Cheers

Any evga 1060 owner  can share their setting ?

[BLNT]

I've got 1 month of ETH mining experience under my belt - Running Win 7 with 1070's/1050ti's -- Claymore 9.7. I manage close to 1.5GH/s at ethermine.org.

I've dabbled in dual mining w/Claymore (using suprnova pools) but would like to try switching one of my rigs to mine Zcash.

Is it as "simple" as what I've been doing already.... just install this miner and point it to suprnova?

Can anyone provide some examples of their text/bat files to configure the miner?

Any suggestions, hints, tricks, and/or tips would be most welcome!

THANKS

Any evga 1060 owner  can share their setting ?

70% power limit, +200 core, +450 memory = 300 sols

Do you know what's the equal of %70 powerlimit in Linux because I use simpleminerOs?

Thank you for this monitoring tool. I've been using it to monitor my rig.

Hey guys,

I've started running 0.3.4b on Windows 10 64 bit.
Supposed to test it with 6x GTX1060 but unfortunately only 2 risers arrived and the rest will be sometime later next week.

So, running 2x GTX1060 (1x Gigabyte WFOC, 1x Zotac Amp) gave me.

Temp: GPU0: 74C GPU1: 73C
GPU0: 316 Sol/s GPU1: 285 Sol/s
Total speed: 601 Sol/s
+-----+-------------+--------------+
| GPU | Power usage |  Efficiency      |
+-----+-------------+--------------+
|  0    |    130W       |  2.43 Sol/W    |
|  1    |    120W       |  2.38 Sol/W    |
+-----+-------------+--------------+

Temp 71-75C
Core clock +100
Mem clock +500
Power limit 116% (max)

Still tweaking to get maximum hash rate taking advantage of my cheap electricity.

Are you in the US or EU? I have a store, I mostly drop ship but I keep risers in stock. I can express them. I had to wait 2 weeks for risers for a rig so decided I'd keep them in stock.

Thanks, unfortunately I'm in Malaysia. I'm going to find some tomorrow.
