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

[Victorio]

1) I am using miningpoolhub coin switching and sometimes when DAG is recreated by coin switch or devfee mining it ends up with all cards having zero hashrate.
Can I prevent this somehow?

I have RX 570 ASUS Strix 4GB in my rigs and MoBos are ASUS Z270-A PRIME.

1. Just a speculation: the DAG of the previously mined coin is not unloaded from VRAM and when generating new DAG for newly-switched coin, the GPU runs out of memory, i.e. you mine ETH, the DAG is ~2.18GB, later the pool switches your task to ETC, with a ~2.25GB DAG. 2.18+2.25>4 GB, out of memory error, OpenCL crashes, 0 hashrate on all GPUs. That might be a Linux-sensitive issue, haven't met it on Windows.
Since you are mining on MPH, you are switching between 4 coins: ETH, ETC, EXP and Musicoin. Is all the hassle worthy the extra 5-10% you get over mining a single chain? Factor in all the time your rigs are not effectively mining.
BTW, I would mine only ETH or ETC. Screw Expanse and Musicoin, first is scammy, later is laggard.

Hi. Can anyone tell me if Claymore has a miner that can mine scrypt algorithm .. or Claymore, do you consider making one ? Thanks.

GPU miners for Scrypt algorithm exist:
ccminer for nVidia (CUDA)
sgminer for AMD
GPU mining on Scrypt has ceased to be economically viable when Scrypt ASICs appeared. First Gridseed ASICs were 400-600 kH/s, on par with mid-end GPUs of that time (2013-2014). Nowadays, typical Scrypt ASICs deliver from 100 to 600 MH/s, 1000x times in performance and 10x in energy efficiency more that first ASICs (Gridseed used 10-15W for 500 kH/s > 50 kH/W and Bitmain L3 uses 800W for 500 MH/s > 625 kH/w).
There exist Scrypt-N and NeoScrypt algorithms, that are ASIC resistant ATM and suitable for GPU mining.

zcash with gtx1080ti + 980ti i have this : (650watt consumption)

It is bad. You would be better off with Equihash coins - Zcash or ZenCash through EBWF or DSTM, mining on an exchange address with autosell option. Now Nicehash-Equihash looks more profitable in the short term than Zcash or ZenCash mining because there are many buyers for Equihash (BTC Gold), but that will fade away in a couple weeks.
I'd take ZenCash, as payouts would be more frequent, every day. Bittrex has autosell option, it sells the coins that get into your wallet for BTC. Or you can just hold your coins, waiting for a convenient exit price.
Don't forget about Power Limit, set it at 75-90%.

@oblione

4x vegas dual mining with no undervolt? That could be using more than 1200W. Check your consumption because you could be hitting the limits of your PSU.

@syncis

Not sure about cutting down on instances, but for the disk make sure you turn off the recycle bin, and if you're feeling adventurous you could turn off restore points. Each one uses 10% of the drive IIRC. Also the Claymore logs can add up after a while.

So would I need to set that in the wattman panel or by using the claymore config file?

Sorry pretty new to mining like this so am on a steep learning curve with these cards.

thanks for coming back so fast fella

You can check your real consumption with a wattmeter. You can use HWiNFO64, GPU-Z, or MSI Afterburner to get a rough "chip power" or "core power" reading (at least with any earlier cards...not 100% sure about Vega), but it will be less than your real consumption, because it doesn't account for memory or other subsystems of the card.

I would recommend latest stable Afterburner if you want to try undervolting if it will work (again...not 100% sure about Vega support). If not I guess you could use Wattman, but it's not the best tool. You could also try OverdriveNTool. Just google them for download links.

Hi guys,

I'm mining with MSI P106 x6.
However, 2 of my cards are not able to run at the fan speed that i've set in AF, which is 65% fan speed.

It appear to be 65% for the first 5 minutes when the miner first launched, then it turn to 0%, sooner it turn to 100% fan speed for 1 of the fan.

My concern is will running 100% fan speed on my GPU kill the card faster ?

As it generates more noise and consume more electricity, can someone share how can i fix this ?

Back then, when i was mining zcash with EWBF miner, i don't have this problem.

I've attempted to reseat all the risers. It appears to b fine for 2-3 hours. after that it went back to normal for the same GPU.

Someone please help. Thanks all.

Does anyone know the fix for the WATCHDOG: GPU 0 hangs in OpenCL call, exit?

using this version with a sapphire r9 380x

Looks like drivers reset because OC too high.  Dial back the OC.

I second that. When overclocking settings are too high, I get "NVML error: cannot get temperature" and "NVML error: cannot get fan speed" in Claymore's log file, and the hashrate becomes null on that GPU.

chanyewhau,
Ethash algorithm is more memory-intensive than Equihash and memory instability manifests itself faster. What is the exact memory frequency - check GPU-Z or another Afterburner skin, that shows the actual frequency? Try to run the miner at stock clocks and PL 80. Sometimes it happens that cards do not hold even a 10% clock increase.
BTW, what memory size and type is installed on your GPUs?
Fans running at 100% will not shorten the life of your GPU, though the fans might fail sooner due to increased mechanical stress (mainly the bearings run dry and might jam).

Hey guys,

Running a 6X480's 4G Nitro + Crimson Drivers, H81 BTC Pro, 8gb ram Win 10 Claymore V10.1 Virtual mem 32gb. Oc through Afterburner 2k 1150 (been stable for well over a month)

Have two rigs running with the same settings and they have been golden for the last 4 weeks. Around 28.5 MH while dual mining Lbry in Nicehash Pool. Then yesterday my second rig crashed and had to be manually reset (couldn't log on team viewer).

But for some reason now I can't run my rig for more than 5 minutes without it getting a hard crash... I've tried running V10 but that also seems to be crashing now. Not really sure what could or might have changed to be causing it to crash now.

Any ideas as to what could have happened? What can I check or change?

Following settings for start.bat
setx GPU_FORCE_64BIT_PTR 0
setx GPU_MAX_HEAP_SIZE 100
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_ALLOC_PERCENT 100
setX GPU_SINGLE_ALLOC_PERCENT 100

.exe etc....
-allpools 1 -estale 0 -esm 3 -ftime 10 -cvddc 980 -dcri 42 -ttdcr 79 -ttli 81 -tstop 85


Edit: Is there a new blockchain driver? AMD settings are saying I should update to 17.11.1 from 17.30. What is the Enable compute options under global settings? I'm not seeing that as an option anywhere

Hello everyone!
I got x4 1060 6G  with pentium 4400 cpu

Im sorry if my question is dumb but i saw an update today (been using 9.8 before) and decided to update my miner.

Features states: - Supports new "dual mining" mode: mining both Ethereum and Decred/Siacoin/Lbry/Pascal at the same time, with no impact on Ethereum mining speed. Ethereum-only mining mode is supported as well.

I tryed it and when i mine ETH+DCR i get ETH hashrate drop.

ETH only i have 98mh\s on a rig
ETH + DCR (- decri 5 as lowest) i get 94.7 mhs + 159 h/s

So eth still drops as before. Is it supposed to be so and i understood a feature wrong or im doing something wrong?
Thanks in advance

[kkourmousis]

@BoostOrDie

Mr. Claymore claims that

- Supports new "dual mining" mode: mining both Ethereum and Decred/Siacoin/Lbry/Pascal at the same time, with no impact on Ethereum mining speed. Ethereum-only mining mode is supported as well.

but I am also detecting a performance drop for ETH. Of course it is relevant to -dcri (and probably to -ethi as well). However, even with the performance drop you mentioned, dual mining should still be more profitable than solo

Post the last lines of your log files.

ETH + DCR (- decri 5 as lowest) i get 94.7 mhs + 159 h/s

Try "-ethi 16 -dcri 15" and "-ethi 16 -dcri 30". Post here the result.
If your electricity cost exceeds 0.10 USD/kWh, dual mining has a slight profitability edge over single mining on nVidia GPUs at the moment. For me, it's not worth the increased power consumption and hardware wear.

I had security set to restrict write access had to remove that and let it run to get a log. Typical it has gone on to run for the last hour no problem

-ethi 16 -dcri 15 Gives 94.2 Eth + 471 Dcr
-ethi 16 -dcri 30 Gives 92.5 Eth + 925 Dcr


My electricity cost is $0.03 per kWh
Power Consumption is the same with ETH only and ETH + DCR = 473Wh  ( On ZEC it raises up to 525Wh)

Fans running at 100% will not shorten the life of your GPU, though the fans might fail sooner due to increased mechanical stress (mainly the bearings run dry and might jam).

The memory size is 6144 MB, memory type is Hynix.
My current OC setting is Power Limit 75%, Core Clock +50, Memory Clock +300, Fan Speed 65%.
With the current OC setting, the cards are running at GPU Clock 1566 MHz, Memory 2152 Mhz. (Based on GPU-Z)
The default clock is 1506 Mhz, Memory 2002 Mhz.

The problematic fan that runs at 100% automatically has the lowest temperature even it is running at 65% like the other cards.
So i dont think the fan switch to 100% due to overheat.

No one likes Hynix memory on nVidia - it has too high latency and does not hold very well overclocking. It's a surprise to know that 6GB GTX 1060 also use Hynix chips, I thought they carry only Samsung and Micron.
Your fan goes 100% because of driver error, that is caused by unsustainable overclocking settings. Since you overclock by MSI Afterburner, check-out the Synchronize settings across similar cards and define lower clocks for the problematic GPUs.

Hello, thanks for your advise.

So i should untick the option in MSI Afterburner to sync the same setting to similar cards.
And define lower clocks to the problematic GPU?

Like probably running at core clock +30? Memory clock +200?

I Got 4 1060 6gb Aorus with samsungs.

I was beating about 3 weeks with strange instabilty wit h my rig. It works OK then BAM! cpu gets loaded up to 80-90% and hash rate drops. Cards seemed ok.
I reinstalled win 7 and win 10 dozens of times. tryed dozens of drves versions and settings.

The problem was EASY - too much overclock!
If you are used to artifacts and freezes due to ooverclock - so in in mining it is strange instabilty. First  sign is MSI AB or any system proces start to use 60-80% of CPU even if miner is stoped! Reboot and lower OC by 5 pints  backwards. watch your rig again until it is stable. then do another -5 and this is you stable OC.

Second sign of GPU error - fan speed in Claymore i 0% i logs.


And dont OC the CORE. ETH needs only Memory OC. Core can be undeclocked for coolnes..

I got 50% power limit, -200 core, +765 Memory. I get 98.2mh by x4 GTX1060 rig power consumtion it 472wh!

You're so on point !
I started to wonder, how come everytime i launch my AF, even with my claymore closed, it takes forever to launch the AF.

Let me try your OC setting. I will come back with the updates.

Thanks alot !

Straight to the point! I had by myself such problems at the beginning, having overclocked my GTX 1060 3GB Samsung to +800 Mem Clk and spent hours parsing the logs, drawing charts, until I said - screw that 1.5 MH/s difference, my tranquility costs more than 5$/month that I'm chasing.
Working at +700 MHz like a charm (2249 MHz).
