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

[TunerDude007]

I have the same issue as Coyn on 2x RX480, since upgrading from 9.0 to 9.1: Siacoin mining speed doubles, but Ethereum mining speed is very unstable and often drops. The cards do not appear to be throttling, temperatur is normal and there is sufficient power.

Adjusting dcri does not help, even with low numbers Ethereum mining speed is unstable. Currently I use -asm 0 to fix it, but of course that causes much lower Siacoin mining speed.

I also use -asm 0 but got the dcr mining back up past 5500mhs by increasing -dcri to 65. Is that dangerous guys? Seems to be running stable tho...

I have 5x rx480's and cant seem to get past 27ish on 4 of them and one is locked at 24. The 4 that are at 27 have 2175  memory clock w/ core clock at 1100 and the 5 is 1100/1750 ... so the question is- how can I modify them? Every time i try they revert back and dont want to budge.

Could you please explain step by step what you are doing so we can try to spot the error...

Solo mining ethereum using claymores v9.0 with: a b250f strix mobo and 1200w psu, 4gb RAM, 5 rx480's (I have 6 but apparently b250 chipset dosent allow 6 even though there are 6 pcie slots). In MSI, GPU's 0 through 3 are all synchronized at 1100 core/2176 memory and any I time I try to change theses values, even with small increments the GPU's stop and I have to restart PC. Same thing goes for GPU4 except, GPU4 is clocked at 1266/1750, any modifications results in the same thing and I have to restart only to come back to their reverted values. When I first had 2 GPU's I could get 29/30 no problem while over clocking in MSI but now GPU's 0-3 are stuck at 27ish and GPU 4 at 22-24ish mhz. My config is as follows:

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
EthDcrMiner64.exe -epool eu1.ethermine.org:14444 -ewal <address> -epsw x -r 34

The restart timer is just an arbitrary value I play around with. In BIOS all I changed was PCIEXx16_2 configuration from auto to x2 (before this only 3 GPUS would catch in device manager), System agent configuration to Above 4D Decoding [Enabled] and changing the primary Display to CPU graphics. I have the 17.4.2 drivers installed for AMD and the latest/most up to date BIOS.

Well. According to your post your have enough knowledge and experience to figure it out yourself
In my opinion you are trying to achieve 2 contradictory parameters - stability and overclocking.
Finding the balance between these 2 is through experiments, like you are doing.

I were you I would revert everything to stock figures. Find the most stable config. Overclock step by step to find a culprit.
I would use 16.11.5 driver - more people using it, it has less issues.
Use DDU and reinstall.
Is your swap file >16GB?

Sorry guys for my noob question but how to actually use it on ubuntu... How to install it?

I may seem knowledgeable but it is deceiving- I am a noob :]. For instance, swap file, is what exactly? If you are referring to virtual memory i set it to the recommended 16gb as per claymores advice. I also tried the recommended claymore driver with no improvements but I will try with the one that you recommended. And as a last resort yes I was thinking of reverting everything back to scratch, but only as a last resorts as it does take time since it looks like I have to restart at every increment of change. I will try DDU as well and get back to you, thanks for the reply!

Hello guys, I have a question. While I am successful mining ETH, I am totally unable to dual mine . Probably is something very stupid I am missing in the options settings, but I am receiving constantly an error from the DCR or LBC pool:

“DCR: Job timeout, disconnect, retry in 20 sec...”

I am introducing as options settings like these:

-wd 1 -r 1 -epool eth.coinmine.pl:4000 -ewal myuser.myworker -epsw mypass -esm 2 -dpool stratum+tcp://dcr-us.coinmine.pl:2222 -dwal myuser.myworker -dpsw mypass -allpools 1

-wd 1 -r 1 -epool eth-eu.dwarfpool.com:8008 -ewal MYWALLET -epsw x -dpool stratum+tcp://dcr-us.coinmine.pl:2222 -dwal myuser.myworker -dpsw mypass -mode 0 -dcoin dcr -allpools 1

-wd 1 -r 1 -epool eth-eu.dwarfpool.com:8008 -ewal MYWALLET -epsw x -dpool stratum+tcp://lbry.suprnova.cc:6256 -dwal myuser.myworker -dpsw fulgor -mode 0 -dcoin lbc -allpools 1

Even using the examples on Claymore's first post with his own wallets I still get those errors

Do you see something wrong that may explain it? Maybe something related to my router or internet provider? :-(

I have the same issue as the above post. I'm fine with mining ETH on DwarfPool but I can't get dual mining with DCR. Always get the exact same issue as described above.
I'm running 9.1 miner on Windows 10 Pro
I have firewall exceptions for the miner and exceptions for folder in Defender.
Are there any prerequisites for DCR mining?

Any help with this would be greatly appreciated.

Thanks,
Hoobski

Sorry guys for my noob question but how to actually use it on ubuntu... How to install it?

first you need to install amdgpupro driver (16.40 or most recent 17.4.?)
go to google drive in first post, download tar.gz file (default to downloads)
drag the file to home folder, double click on it, it will ask "extract" yes to home folder (by default since archive is now in home folder)

in terminal:
export GPU_FORCE_64BIT_PTR=0
export GPU_MAX_HEAP_SIZE=100
export GPU_USE_SYNC_OBJECTS=1
export GPU_MAX_ALLOC_PERCENT=100
export GPU_SINGLE_ALLOC_PERCENT=100

then right click on Claymore's folder in home directory and from the pull down menu choose "Open in terminal"
then use command strings from ethermine.org and add whatever you want from the OP's first post in this thread
just make sure that command is formatted properly (./whatever)
use -mode 1 just for ethereum
use -etha 2 for amdgpu pro drivers

Is there a nvidia start thread ? i dont know whats missing or its just the driver but i cant start the claymore miner just dies right a way, we still need the cuda 8 and visual studio right sorry been some time since i was mining
i have 2x970 that need work

Hi people, first sorry for my bad english, my problem is that i buy 4 saphire nitro (no plus) RX480 8GB, and i think i did a very bad buy becouse this model https://www.amazon.com/gp/product/B06VSWDK2H/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc=1  it has only 1750 mhz of memory clock and i think that it dosent have doble bios option. I buyed becouse i did not know that there where 3 diferents models of nitros... my question is, how much less hashrate will i have with claymores miner? and does standart bios mod for nitro+ work in this version or do i need a different one?

PD: I read that peoples gpus are dying for using dual miner ether/+ and for mod the bios, i do not want to happen to me, does it really damaged your card to mod the bios and do dual coin mine?

You have to create an account on Coinmine, log in and create worker and worker's password so it matches with your miner's bat/config file

- Its not a BAD card. Its is a cheap card. This is why you chose it in the first place. So you already saved some money. Why regret now?
- You still can mod Bios. But modify it yourself rather than use someonelse's. Follow step by step instructions bit by bit (can be easily found via google).
- You should ask questions on the forums where you read "that peoples gpus are dying for using dual miner". I did not see anything like that in this thread.

[stanis_r]

claymore ethereum v.8 and v.9 for some of my cards shows fan 0% or -1%. what is the problem. i uninstall MSI AB and the problem is the same.

i have a visiontek 460 that shows 0% fan in cdm. different drivers, several versions of cdm. all read 0% for the 460. my others cards, 390s and 470s read correct.

msi ab shows correct speed and i let the cards manage their fans so i just ignore it. runs fine otherwise.

How much mghs I can get on R9 280x?

How much mghs I can get on R9 280x?

14 or 15? You're better off mining Expanse or Zcash or something else than Ethereum.  Expanse is more profitable because you can mine it so much faster that even though it isn't as valuable as Ethereum you can mine more of it.  You can even dual mine with Expanse and DCR or PASC or whatever.  Expanse simply replaces Ethereum.

This is a pretty good run for me.



a lot of incorrect shares though. :/

Dcr will have an unusually high number of rejected shares, dont fret. What DCR settings are you at? This looks like 40+.

[crypsy]

can  you share your  batfile

This is a pretty good run for me.

Mines are at 107:05 now
Pretty sure I got some sick number few days ago, but power shortage resetted the counter.

Thanks dude, well actually y buyed not only becouse it was cheap but becouse i saw in the forums that its the most used card for mining, but i didnt know that this particulary version it dosent have dual bios and the memory its lower, im asking if they will reach 30/31 mhz has the other models or if it is better to sell them and buy another one before i open the box.

And yes for example in pag "479" someone said "6 msi -  3 sapphire nitro and  2 sapphire reference cards died all during past 3 weeks.... I dont even know what to blame now. Bios mods... motherboards.... PSU or claymor v9"

[Qazo]

is this to much incorect shares for ether?  rig is stable as rock for almost a week
speed fluctates too much for my taste, but that is "normal" on rx400 series, on pool average hashrate is 6-7 mhs lower than reported, i think it's ok
