Claymore's Dual Ethereum AMD+NVIDIA GPU Miner v15.0 (Windows/Linux)

[ChrisJ123]

Whenever I run the batch file I get the following message using Claymore Dual Miner:  

ETH: Stratum - Cannot connect to us1.ethpool.org:3333
ETH: Stratum - Failed to connect, retry in 20 sec...

I have tried numerous pools.  I would really appreciate any help into understanding why this happens.

What is wrong with AMD GPU at Dual Mining ?

My Dual Mining Settings:
EthDcrMiner64.exe -epool eth-eu1.nanopool.org:9999 -ewal MyAdress -epsw x -dcoin sia -dpool stratum+tcp://sia-eu1.nanopool.org:7777 -dwal MyAdress  -dpsw x -ftime 10

Try to play with -dcri key. Set it about -dcri 10 and press + / - in miner window to find the best value

Thank you, i think it is ok now.

What are your clocks for your 1080ti? I'm only getting ~32.5mh/s Eth and ~2450mh/s Dcr while dual mining.

Can you access websites from the miner?

Is port 3333 outgoing blocked on your router?

Dual Mining is NOT stable.
I returned to the ETH only mode.

I have stability issues when dual mining too, sometimes the rig works for more than 24 hour and then without any problem hangs, nothing in the log. Sometimes it can't mine for more than 10 minutes and I was forced to return to ETH only.

You've used -ethi 0 and it's still not working?
The most low GPU load is "-ethi 0".

Is it normal to have only 16% gpu usage on HwInfo ? 

i'm getting about 230 Mh/s @ 1000watt ( 4 rx480 + 4 rx 580 )

That's awesome. How is this possible?
My 2x R290 needs 550W for 50Mh/s

Any chance to revert the new gpu indexing method? Or have a switch to change it between new and old. Claymore stopped working with NiceHashMiner after the changes, it is always the wrong gpu that starts mining, when nicehash starts claymore.

If you really need it, use "-dontsortgpu 1" option (undocumented).

thanx!

i think  i found a bug:

- on my AMD rig  the command -r 60 restart claymore every 60minutes like it should,
- on my NVIDIA rig the exact same command restart the whole computer... why ?

Can anyon e help me to avoid this?

My wife's PC is doing this everyday for few hours.
My PC is fine (same bat file, except worker name)

Thanks.

Check your network connection, if you use wireless, change it to cable.

Does anyone know what the most common/probable causes are for a gpu hanging?  One of my RX580s hangs after about 15 or 20 minutes every time.  Very frustrating.

^ lower the OC

Has anyone heard a timeline for undervolting on linux?  Seems like we are waiting on AMD to provide proper driver support, is that still the case?

THanks

It's on wireless, you might be right. While my main PC is on cable.

Hi guys, I have a noob question here. How do I set the following environment variables in Ubuntu?

GPU_FORCE_64BIT_PTR 0
GPU_MAX_HEAP_SIZE 100
GPU_USE_SYNC_OBJECTS 1
GPU_MAX_ALLOC_PERCENT 100
GPU_SINGLE_ALLOC_PERCENT 100

I know "setx" is used in windows, but how do I do it in linux?. I've tried Google search but could not find answers. TIA.

use "export"before the line

Are you undervolting at all on ubuntu?  If so, how?

USE THE COMMAND "EXPORT"--

At the top of your BASH script, place the following:

export GPU_FORCE_64BIT_PTR=0
export GPU_MAX_HEAP_SIZE=100
export GPU_USE_SYNC_OBJECTS=1
export GPU_MAX_ALLOC_PERCENT=100
export GPU_SINGLE_ALLOC_PERCENT=100

Please note that the syntax is slightly different.  An "equal" sign is required.         --scryptr

Thanks for the suggestion.  This GPU ran stably for three days straight before I shut down the rig to add a few more GPUs to it.  Now this particular GPU is hanging every time, so I don't think it's the OC.

Any other ideas?
