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

[monsanto]

Damn, my 290x (Hynix) keeps crashing (on stock settings) after few hours of mining. Program freezes so bad that I need to restart computer. I got 2 rigs each has 5 gpus (280x, 290x) and I only got problem with 1 card. I tryed the card which crashed on both rigs and I get same results. It works good on claymores monero miner. Is there anything I can do? Any ideas? I had this problem on all versions.

Have you tried lowering eth mining intensity with '-ethi'?  Default is 8, so use -ethi 8,8,8,8,7  with 7 where the bad GPU is, then try 6..5..4 etc until it stops crashing. Are you dual mining? if so try lowering intensity of whatever else you're mining.

UPD 2 Mr.Claymore I can repeat this bug now. It happens only with "big" config files and happens only when killing the EthMan.exe process in the Task manager. I also see that EthMan is trying to save the config file, even if it is killed abnormally. And I suppose it just has not enough time to finish the save operation and flush the disk cash.

Why do you kill EthMan from TaskMan? EthMan saves data at exit and it can cause this issue. EthMan cannot detect that you kill it abnormally, TaskMan sends normal WM_CLOSE message firstly, in Win7 it waits then, don't know about Win10.

Why? Because, as I said, I couldn't close it normally. It came to a state, when all miners were red colored as they were not available. And EthMan didn't respond to a "Close" command. It happens earlier or later, but it happens, if EthMan runs for a long time. Can I provide you with any additional helping info? Mmmm, may be... As I said before, I have two EthMan windows opened. Next time I see one of them hangs, I will check if this one gets config wrecked, not the second one, that runs normally.

P.S.But you have at least 2 options:

1) Wait 0.5sec before writing the config at exit
2) Perform a crash safe writing. So, write the temp file first, then make a copy of the current file as "*.old" and finally rename the temp file to a normal name.

after some testing it seems that when the sapphire ref cards get too hot the MH/s drops from around 31.5 or 30 (depends on card) to around 27-22MH/s and keeps on throttelling and jumping all around the place.

since now its winter here in germany, this isnt such a big problem for me, but i plan to take the rig with me to a much hotter country in the summer and im afraid this will be far from ideal setup.

also im currently using some XFX rx 480 8gb RS, where i just copied a memory strap. they seem to run stable at 28mh/s even when the sapphire cards start to throttle. so i believe they will be the right choise for me for the long run. also im about to get one sapphire NITRO+  480 8gb card and try to flash and OC it like some guy on youtube did to get like 30.5 MH/s.

question is, any of you guys are living in hot climate regions or simply run your rig in a hot poorly ventilated place? i would be interested to know what you think about the optimal setup for such places Roll Eyes

@claymore hi and thanks for those miners , you deserve your fees
but you have to improve the stability of this miner , i m new in mining with 4x rx480 8go actually

Ethdcrminer64.exe stop work at launch most of time when :

Code:

start building OpenCL program...

this problem is not new , i see some people have it to since older version  ....

this coming 4 time on 5 launch , i try windows 10 & windows 7 both have this issue with differents drivers, and follow the troubleshot ...

all visual c++ are installed , etc.

ZecMiner64.exe never stop like this, is fully stable. the only crash was on v7 when devfee mining sometime

please please  improve the stability of this ETH miner.  

seem the problem is with amdocl12cl64.dll

I used to be able to edit config.txt before.
in new version it says default is "read-only"

How to change back this behavior to change it to "read-write" so I can control my rigs on lan?
Thank you

Which "new version" do you mean? It is in ZEC miner, not here, isn't it?

Readme :

-mport   remote monitoring/management port. Default value is -3333 (read-mode), specify "-mport 0" to disable remote monitoring/management feature.
   Specify negative value to enable monitoring (get statistics) but disable management (restart, uploading files), for example, "-mport -3333" enables port 3333 for remote monitoring, but remote management will be blocked.

so, make this must enable management :
-mport <positivenumber>
ex :
-mport 3333

Right now all of my miners stopped working (2g cards) is there some explanation, I tried reboot but same thing it doesn't work - OpenCL error -4 (0) - cannot create DAG on GPU


It's interesting that I have rig with 4 gpus all 2G and GPU0 works but the others - OpenCL error -4 (0) - cannot create DAG on GPU

Any ideas?

Just hit DAG epoch 90, so by default the miner will allocated enough space for epoch 92, which is the first DAG that is too large for 2GB cards.

Try -eres 0. That should buy you 1-2 more DAG changes. Reality as we have always known, is that 2GB cards won't be able to mine eth anymore quite soon.

Claymore vashym following a manual set miner .Set Crimson Edition 16.9.2 driver, a miner working 2 days. on day 3 system hangs ...
Once reinstalled driver Crimson Edition 15,12 betrayed oshybki system to terminate the miners ... After following the removal and so on. ..
When you create a restart file, the system refused to respond, with the outlet turned off ...
I can not find a solution to this problem ..

The same. My r9 270 GPU stopped working with claymore. I'm still mining ZEC.
qtminer runs fine with this GPU but hashrate is low.

Maybe I have to take this out of my rig.

Ok, but then why 1 from 4 cards working? Without any sets of -eres?

Hi! Is there a way to automatically restore -cclock -mclock -cvddc -mvddc settings after miner quitting? I use PC for gaming sometimes, and on miner I underclock and undervoltage GPU core to save energy. I need to reset settings manually in Wattman after closing miner.

Hello

I use the miner for the hetereum only,

But I would like to use claymore has 100% of its mining capacity.

What cryptomonism should I use to optimize my profit?


And we do not lose hasrate ethereum with double mining?

Thank you for your advice.

Thank you for your advice.

you loose a bit Hashrate , you have 2 % fee , and your watts are up. and it s not stable. continu solo , other cryto are too low

Maaaaaannnn,
This miner is awesome,, 2 years i go,, i started with then.
And now this new.. remote manager issss verry nice Thanks.. and guyys just pay the fee and be happy to target results mine.

I JUST WANNA ONE THING FROM YOU CLAYMORE..


Do a remote manager program to IOS and android =)


Thanks for your great JOB!!!!

  Hi King Claymore!!
Hi people!!

First of all thanks for this great miner ...
but I have a problem with 6 GPU...(with 5 GPU's all its ok)
Very often appears the miner sttoped I check the log and I can see GPU #5 hanged.

I have similar problem when I put 6 gpu to any rig that I have, its stop sometimes ... with 5 gpu, unlimited days without problems.

Is it posible to reset this GPU 5 when hangs occurs??
Or the whole miner...?

I try with ethos and only stops one GPU, with your miner I try some diferents version with the same result.

I try with identical all 6 GPU or combinations in my rigs.
sapphire RX 470 8GB
asus RX 480 4 Gb
MOBOs z97x-Gaming 3 with 4Gb RAM and Intel Celeron G1840 2,8GHz


thanks a lot in advance!!!

I think with the '-r' flag.  I read that '-r 1' should run a reboot.sh script when a gpu fails.  I think other numbers will let you reboot just the miner etc, (read the post on the first page for details).  I'm trying to get it to reboot the entire computer because it just hangs when trying to reset the miner.  I can't get it to call the reboot.sh script though for some reason.

Thank you so much for information. I have read the file. I am using a virtual desktop in my os x which handles my 3 rigs. I am using positive port number. I can observe/monitor all of my rigs but  still the dialogue for edit config.txt or edit pools.txt does not open notepad or any such editing software.

I guess the 6th riser for the GPU or the GPU ASIC itself may be an issue. Try to give some more juice to all the cards (+ 20mv to at the least  +30mv). And see if the card fails. I had similar issue. It was about 1 card hanging under pressure.
Best luck
