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

[Dowper]

Hi Claymore. Im using your miner and often see this in log files: "DCR: weak share, skip". What does this mean? Im loosing money or it is normal?

Same here, I mine DCR on coinmine.

So, I have a problem.

I have Ubuntu 16.04 with two 4Gb rx 470s (red devils) in pci-e slots. Miner hangs after the "1 DCR pool specified" line. Before open CL initializing. I was able to make it work randomly, but it hangs with "DAG buffer allocation" error after a few minutes.
If I remove one GPU from the slot it works perfectly fine.
I have similar rig with Sapphire rx 470 and 480 in two pci-e slots. It works fine.
Maybe, I need configure a driver?
I cannot work out a solution. Please, help!

Ok. I have some additional information.

Code:

For some reason second card has no driver. Any suggestions, please?

Is there a dual miner ETH/zec scheduled ?

There is no point in an ETH/ZEC dual miner because both the algos stress the GPU similarly. Dual miners only make sense when one algo is only core focused, and the other is only memory focused. That being said, you can run both claymores ETH miner and ZEC miner together if you reduce intensity for both, but its half assing the whole thing and doesn't make a lot of sense.

I don't understand, it happens on regular bases, miner is working with 3xRX480 and suddenly one card drops to 7MH/s-4MH/s and then the OpenCL error appears, why it happens or what is the cure ?

Most probably you're over-clocking too much or under-volting too much. If that's the case, try mining with some less values.

Else see the temperature of the graphics cards, check if any of those is getting over-heated. If everything's alright here and there, you might have to change the driver and OS.

The thing is that they are working since the September without minor issues only, like hangs and stuff, but now most of the rigs hang with no reason, I mean the OpenCL errors are more constant, GPU hashrate drops as well. I haven't updated anything on some rigs, nor drivers, as I said they are working since September.

[doktor83]

so if you did not change anything, why do you think the miner that was working so long is the guilty one here ?

what do you mean under guilty one? All I wanted to say that nothing was changed on most rigs which were working almost perfectly and now 30% are getting low hashrate and opencl errors

[BogdanCo]

Claymore it's possible to have a dual mining ETH+DMD (Diamond)? DMD lately became very profitable to mine... Thanks!

Have you considered ambient temp changes as well as epoch advances?

Hi! how to launch miner for AMD card only? my nvidia760 restarts miner all the time...

[pulec777]

This is good miner.

RX 470 Nitro+ 8GB (samsung) bios mod strap 1625 timing, -96mv, core 1050, mem 2050 = 74w @ 28,4Mh/s ETH

Use the -di option

Trying to run this under linux.

Stock 16.04-server system

I installed CUDA drivers as described here:
http://ethereuminfo.blogspot.ca/2016/03/mining-ubuntu-server-1510-bare-metal.html?m=1

When launching the claymore miner (which I have working ok under windows so I believe my config flags are correct) I get the error:

./claymore/v8.0/ethdcrminer64: error while loading shared libraries: libcurl.so.4: cannot open shared object file: No such file or directory

Also:
$ sudo apt-get install libcurl
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package libcurl

$ sudo apt-get install curl

Reading state information... Done
curl is already the newest version (7.47.0-1ubuntu2.2).

What am I doing wrong?

It appears that 8.0 has a severe memory leak.  The miner reached 13GB of memory usage. This is no small leak that is a major leak. When it got that heavy it stopped sending out hashing power even though it was mining the remote manager said it had no hash power.

[Antonious]

Good morning. Is it really possible to decrease the incorrect share's on Etherium, not rejectet, but incorrect ones? According to WHinfo, there are no errors on memory, but still 1.5% incorrect share's on etherium, and 2% on Decred rejectet share's. The pools are coinotron and coinmine. Does it depend on the pool? What do I do to reduce losses? Removed overclocking, lowered the frequency of memory, but it still happens. 6x SAPPHIRE NITRO+ 480/8Gb. 177 Mh/s on Ether + 4400 Mh/s Decred, dcri 50.

EDIT: I am using QTminer successfully for the time being until i am able to resolve this

HELLO THERE! I am a noob to ethereum but claymore has easily caught my eye to being one of the best miners... however
it seems I am stuck up on being UNABLE TO USE IT

FIXES THAT I TRIED
I have downloaded the latest NVIDIA FILES
I have also downloaded CUDA 8.0
And at the settings bellow all the stability features of the software i have added.
change page file to 16GB and 20GB (by cryptomined on youtube but did not work for me)

However.... the mine will always restart itself.

Here is the rundown on how the software would stop (and restart) it would always be like this

GPU 0, GpuMiner cu_kd failed 8 (0), invalid device function (ERROR ISSUE)

After restarting the error would loop. any suggestions?

You need videocard with 4 Gb RAM. 2 Gb not enough to create DAG file!!!
