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

[Ursul0]

When I still had my 8-gpu rig consisting of MSI Gaming X 580 4gb elpidas, I'm having similar problems as you. They're smooth and all but they only hash 29.6 if all eight cards are connected.

If I only plug 4-5 cards, they hash a terrific 30.1 up to 30.3 each.

I've created a thread here, in another board and even in ethermining sub of reddit but apparently, not too many miners have 8-gpu rigs to contribute their thoughts.

I'm in the process of building 8x Nitro+ 580s on Saturday and I hope and pray that it's not going to be the same experience as the Gaming X's.

lol... I've got seven 570 rigs with 8*MSI gaming, 8*asus expedition, and 8*Nitro+ mostly elpida, some of those also have 2-4*1060 Palits 6Gb all on Asrock h100 btc.
The issues I'm having with dual claymore v10 & blockchain drivers:

1) the main problem is that some cards like to go down to 24-25 from regular 28-29. On some rigs first boot is almost guaranteed to be this way, often it's 28,25,25,25,25,25,25,25... but on anothers it may come in a few hours after reboot. (if it comes later the cards become very unstable and often crash, even on 1800Mem and 1080Core settings. Didn't check the stock timings yet...) Sometimes these all can lead to win hung, but now just installed watchdogs, so this is partially solved:)

2) Another issue is that Nvidia may fail to allocate dag and several reboots(sometimes even 5-6) may be required to get rid of this error. Also may lead to win hang.

3) And finally extremely irritating issue with EthMon: I've got one rig (one of the clones, so nothing special about it) that after 10-20 hours looses connection to EthMon, and will appear red, although working fine.
 

Curious what mobo do you use with your 8x gpu rigs?

Also, are you having a similar problem as mine? 8x gpus mine slower when all is connected ? or they mine the same as connecting a single GPU?

Using 8x GPU Nvidia GTX 1070 FE, on windows, Asus Prime z270-a works like a charm 32.100 Mh/s on each card total power 860Watt/h. but i had a big time hassle while i was trying to install the 8th card cos of the cheap m2->PCIe connector , everything  solved when i use a better m2 ->PCIe from amazon --->> Explomos M.2 Key

Nvidia drivers are more stable in general, yet now less profitable in a way. Also WinX(addiversary) will boot into blue screen if more then 8 AMDs installed.
MORE: to the above setup now out of 7 rigs: asus seems to be the most stable now at 1975-2000 and core 1120-1140 with 875mv. MSI gaming are really cool and smooth. Trying to exclude display (dummy/monitor issues now) some instability in 2-4 cards out of 64, including some vega pairs

@Claymore that would be awesome if you'd add another line with option for custom labeling (per GPU notes)  to the miner entry in the list. also so it would be possible to disable/enable such view (EthMan 3.4)

i have a gtx1060 6gb but my pc is lagged i think it's not normal   and i don't see my coins on etermine, what can i do? thanks

edit:w7

Please give us more detailed information on your system, at least give us your .bat configuration, PC specs, error encountered if any, or some screencaps will definitely do.

we are glad to help, but we do not do witch crafting with magic crystal balls knowing what is really going on to your system.

Why hashrate reported by Claymore and average hashrate reported from nanopool and ethminer have -minus 10% difference for me? Never had over reported hashrate for 24 hours.
That is noticed from 2 weeks, reported by Claymore - 394 Mhs, but average reported from ethminer pool 347 Mhs. That is too much, Rigs are only restarted 2 times a day for 2 min max time for reloading.
Who is giving us wrong values... pools or Claymore 10.0.
Is it possible Claymore 10.0 just pump hashrate to use it preferable to other minersoft?
Need users who have same difference .

Recently stale shares have become pretty high due to faster block times with Byzantium.  Some people are seeing up to 10% stale share while most are around 3-7%.

Hello,

does someone facing hard reboot (without any info .. just like on/off on PSU) with Claymore v10.0 on windows when mining (in dual mode) and connection to both pools get lost?

Regards

I get this after sometimes when the oc is too hard.

Okay, after 3 months of mining during the last couple weeks rig has been freezing and the last line of the log file indicates:

GPU got incorrect temperature 511 ignore

Thoughts?

I got this error when one of the fans on an RX580 failed. I don't know how long it was running with one failed fan but when I noticed the failed fan the card was very very hot !

In that case, the temperature was so high that the card itself couldn't measure it and that's why you got GPU got incorrect temperature 511.
That's my guess.

No, the card didn't respond - so it returned an code meaning invalid, which is what you see.

I see. I guess that there are several reasons why card didn't respond.

His implementation does a little better than the ethminer (genoil or otherwise) ones when it comes to speed on the compute side - i.e. the computations. He also benefits from a technique I also use - somewhat poorly implemented on his side, yet likely somewhat effective - that is, executing some operations "for free" because the memory read is being done at the same time. This also increases the speed relative to the other public miners, and the side effect is (of course) the ASIC is idling less of the time... resulting in your raised power consumption. Appears to be touched up output from the AMD compiler ( well, almost certainly, seeing as it left the little love letter "@(#) OpenCL 2.0 AMD-APP (2442.12).  Driver version: 2442.12" as well as another noting it was used with the compile option "-legacy" )

ohh is that what's he's doing, no wonder it seemingly has very hard to find sweet spots profiling measurements and parallel processing through asm optimizations, under loads is very effective, yet less scalable and stable under various conditions than 'clean' implementation. - proper (not fine tuned for specific results asm optimizations that can benefit from compiler targets optimizations as well. but then he uses his own custom environment ...

EDIT: looks like on various timings and clocks [increasing the core clock then should be generally good solution for 24mh drops] it can also produce "interlaced like" fragmented memory load [mem read is done, but the filled in stuff isn't:)] and thus power draw inconsistencies. will check though with adding more RAM, so maybe not. AMD blockchain and new API is not very nice. Is there an update we should expect from him in a few weeks?

make sure you have your windows os installed in UEFI mode, that may ease your pain. z270 has lots of pcie lanes
EDIT: I'm sorta blind occasionally I guess...

yep. also fast ping times becoming more important eth matures slowly, important not to get too fat and lazy

[Vann]

The problem is the share difficulty is too high for the current block times of <14 seconds. By the time your worker gets the new job and sends back the result, the network has moved to a new block more often now, which results in a stale share. Pools need to adjust the share difficulty to match the current block times.

[delwig]

Has anyone else been getting less speed since yesterday on amd cards? I lost about 5 Mh/s on my rig

Make sure Windows didn't update the drivers automatically. On Windows 10 Pro you can set Windows Update to not include drivers. Type 'gpedit' in the search box and in the Group Policy Editor navigate to Administrative Templates ==> Windows Components ==> Windows Update and set 'Do not include drivers with Windows Update' to enabled.

Awesome miner works awesome with stock Windows

nah no driver changes, I dunno it is weird.

I have 3 RX580 4GB and they have been mining at 29 mh/s for almost 2 months now. I didn't see a drop nor and increase.

GPU mining wont be profitable soon, save up and wait for FPGA/ASIC. They will be expensive.

Hi Everybody!

Please help me this my issue. Ive been mining for a long time with rx 470 4gb using AB to undervolt. Setting -100 mV and getting -96 mV on AB menu . Well, okey.

But in monitoring graphics in AB I see different values of core power on each GPU:  0.968 , 0.937 , 0.981 , 0.943 , 1056 mV. I was fine with that cause I lowered power consumption on whole rig.

But why is that ? Why different values ?

[Victorio]

But why is that ? Why different values ?

Different ASIC quality. Each individual GPU chip has its voltage level needed to maintain a set frequency.
It is also called "silicon lottery".

[voidwalker]

Hi. So I bought 8 vega 56 to make a rig, thinking it would be no different than a 1080ti rig.
I can only get 5 cards to work on asus z270-a, the rest are not recognised, and sometimes a 6th comes up with problems in device manager only disappear at the next reboot. very strange.

Do you know what motherboard/driver etc can get 6+ cards running on windows ?

On linux I couldn't even boot with more than 3 cards, it would give me some pci express errors.

Also, what miner works with vega on linux with the 17.40 + rocm drivers ? or is there any way to enable old opencl for vega ?

Please advise. thanks.

it's even more as he's changed his address in mid 2017, i found some old logs with the previous address . And he has some other miners, which add to his crypto diversified portfolio.
In regards to your question - if it was me I wouldn't answer on such type of question, no offense here. I hope you realize difference between 'yours', 'his miner's' and all 'others's in between (environment&hardware) related problems. On top of that, you always have a choice - looking into someone else's plate will almost always lead to a depression...
