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

[kenbeannet]

From what I have read (After 60 pages), I cannot seem to find any answer on the error "GPU#X Got Incorrect Share".  Can anyone explain how to resolve this?  I have been lowering MEMORY clocks slowly, but they dont seem to be disappearing.

Thanks!

Yep. Claymore supports 10 GPUs max. Try running claymore for the 470s and ewbf (equihash) for the 1050s - you'll make more that way anyhow

This is factually wrong. . Claymore supports more then 10 GPUs obviously as most of my rigs have 12.

Hello,

Trying to set up multi gpu system.

8 NVIDIA 1050's and 5 AMD RX470's on Asrock H110.

Is there a claymore GPU limitation I am missing?

If you read Claymore´s README file you will learn limit is 32 GPU and not 10 GPU

Hello,

Trying to set up multi gpu system.

8 NVIDIA 1050's and 5 AMD RX470's on Asrock H110.

Was working well with 8+1 but after adding the last 4 the miner now hangs on startup.
Tried versions 9.7 thru 10.2, no luck.

Is there a claymore GPU limitation I am missing?  All cards are installed properly in windows and patched blockchain drivers for the AMD.

The nvidia are a bit older drivers but seem to have the best luck with them for many months.(newer ones were not stable).

I tried the -gser settings but just delayed the hang.

Claymore loads the AMD cards, and them pauses, then eventually locks the entire computer.

Any ideas? 

Thanks so much!  Any suggestions are greatly appreciated.

most probably your PSU is not enough and it is not a GPU limit issue (Claymore limit is 32)

Most issues I have seen were due to inadequate or failing PSUs.

@Claymore: I'm getting some weird behavior on machine where I test possibly faulty raisers see log below:
Note: sometimes I also experience the "lost from EthMan worker" issue - after some hours of work it disappears(now on v10.1) from EthMan 3.2-3.6 (while the worker itself is hashing just fine) are there any (EthMan?) logs that I can enable so I'd get some idea as to what is the problem?

This is not the case anymore since 17.10.1 drivers, please do not confuse people

who can help me?
i own 18x 1060 3gb

i always mined eth or whatever ethash alghorytm with this cards

lately about 20 days or so.. i get big drops hashrates why?

i have 4 rigs and all do the same i tried with overclock, stock, low overclock, changing drivers, i treid all, but i get big drops.

1 rig does 143mh (24.7mh *6) about, every 1 or 2 minutes claymore say 80mh and the cards show they are doing 13mh why? this happen with 4 rigs and never happened before there i s some reason of this?
in the pool i cant see a constant hashrate but high and low hashrate.
thanks who can help me

Double up the PSUs on one of the rigs and see if that stops it, PSU & GPU power efficiency can drop significantly as they age.

no problem with gpu

i have 4 rigs and all have hasrate drops

OC settings does not work with 17.50 (17.12)

I did not found any other utility that can set OC for AMD graphic cards from commandline in windows (or linux)

you should try overdriven tool for windows: https://forums.guru3d.com/threads/overdriventool-tool-for-amd-gpus.416116/
it works just fine for my AMDs

[Ursul0]

overdriven tool keeps my polarises where I want them.

and well... yeah. the 17.12.1 makes temps & fans speeds invisible to claymore.
I'm no worried though(even too lazy to downgrade drv version) as there no reason for me to use claymore for polarises fan control/temps in the first place:)



P.S. this forum is half dead ..too much crowd here...

Any chance of dual mining eth and cryptonight?

I would not imagine it could be possible without significant downgrade in performances of both.
The reason dual mine is possible with eth is that this algorithm is memory read intensive, so I presume claymore works this way: during the times that core is waiting to get data from a memory read (during all mem latency clocks)  it actually hashes other non-memory intensive algorithms.
And Cryptonote is somehow both core and mem intensive

Is it possible to just mine the '2nd' coin with claymore?

I want to straight mine decred on a few cards rather than run eth+decred.

I remember Wolf0 to claim in Eminer (another Ethash miner) topic that he works on a private dual miner for Ethash+Cryptonote.

No, Claymore supports the dual coins only additionally to Ethereum. Solo mining Decred via sgminer or ccminer is less profitable for AMD Polaris, I've run benchmarks.
IDK about other cards.

Hi!

I am dual mining ETH + LBRY and it seems that my rig lacks electricity to work well. After a few minutes, lights start flashing and the rig is hashing very poorly. I don't have this issue with Sgminer.

I don't understand as I only have 8 x RX 570 4GB at 950 vlt so it should not exceed a 15A circuit. I even tried to split 4 cards on one breaker and the other 4 on another one.

Any suggestion? Thanks.

8 RX570 dual mining @.95V should draw up to 1600-1700W, 15A@110V.

Do you know what home wiring you have? Copper/Aluminium, wire gauge? Grab a power meter and check the consumption.
Lights flash because the voltage drops. It's a potential fire hazard (voltage drops, power stays the same, current increases, wires heat up).

Thank you for your answer Victorio! Wow I was not expecting it to be that high! I have no clue about the wiring unfortunately. If the voltage drops it means there could be an issue with wiring or something else with the electricity? Sorry I am kind of noob with electricity haha. But with only 4 cards on a breaker the lights should not be flashing no? I mean it should be max 850W.

Thanks.

120Volts (USA) x 15 A fuse.  1800watts.
you can safely load up to 80% which is roughly 1450 Watts.  Anything above you risk.

Do not forget that you may have other things on this fuse as well, it is not per socket, but per room or rooms.
i.e. even if you use two sockets in the same room, they would be on the same fuse/breaker.  Sometimes even 2 rooms can share this 15A (i.e. 1x 15A for 2 bedrooms)


RX580 Dual mine is power hungry and is using way too much.  
Try single mining and you should be ok.

tadeus1  Right! so in your opinion it's not worth it to dual mine? I do ETH + LBRY.

[tadeus1]

I agree that RX570/580 is very good on the LBRY when dual mining with ETH, but for me its not worth it.  Too much electricity, too much problems if you have 6+ GPUs and your electrical system is not scaled for this.
dual mine vs electricity usage Works much more efficient on nvidias. But thats my opinion. That is why I dont dual mine on my ATIs, only on my Nvidia.

example:  RX570 - single mine ether, 125Watts,  dual mine ether+lbry  goes to 180-185watts.
Nvidia 1060 stuck at 85-90 watts (with lower TDP but still efficient mining hashrate).  dual mine eth+lbry.
