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

[xeridea]

Claymore, run some test on rx480 to fix the fluctuation problem on rx480 cards.

I use stock cards for tests. Yes at some dcri value I can see memory controller load deviations in GPU-Z, it's about 90% but then it's 65% for a few seconds. For my Nitro+ 480 I see it at "-dcri 47". Try to increase -dcri value a bit, for me "-dcri 50" is stable.
Of course your values will be different if you use different card/bios/clocks.

Yes it is stable with dcri 50, however it decreases eth hashrate in greater amount.
Instead, if possible could you please double check miner code and see if miner works stable, without sacrificing ETH hashrate? For me "-dcri 30" is the most for ETH >> 29.3 ETH, 875 DCR but when using this value, gpus randomly have memory controller load deviations in GPU-Z, and this is seen through miner console. As a result lower effective hashrate is calculated on pool.

What if you use "-dcri 35"?

i tried that

with -dcri 30 i get 142 on eth and 4200 on dcr
with -dcri 35 i get 132 on eth and 4600 on dcr

it's stable but eth hashrate is much lower

What if you use "-dcri 33"?
Above I marked the key phrase ("try to increase -dcri value a bit"), but it seems I should say values directly...
I understand you'd like to see x2 hashrate and smooth work, but hardware has different opinion, memory controller goes crazy at some -dcri values and I don't see any workarounds for now (without losing hashrate).
For stock clocks/bios, increasing -dcri value +3 gave me -0.5% ETH of maximum but stable hashrate. May be it does not work for modded bios, I don't know.

I get 27.3 and 1150 on a Sapphire 480 8GB, 1750 straps mod, 1270 core, 42 dcri.

470 8GB 1750 strap I get about 27.3 and 720, but running 1100 core, 26 dcri.

For some reason Red Devil cards don't play well with v9.0, best I can get is ~1050 on 480, need to set -ethi 10, default 8 has rollercoaster ETH rates.  

Also, thermal throttling is very bad for v9.0, since varying speed via -ttdcr causes rollercoaster a bit, since miner takes longer to settle in, so may want to use lower clocks/volts/dcri if your ambient cooling isn't the greatest.

[hzavarce]

You have to edit the dcri value to try to find a stable setting in V9.0. While in runtime you can you + and - to change it, find stable values for each of your cards, and then set it in the batch file.

Tried - to change it going little by little but even when I reached the same speed I had in 8.1v it still gives me invalid shares to the point the pool disconnects, no idea if it is because of my custom bios, 173 MH/s ETH and 2603 Mh/s DCR on 9.0V 173 Mh/s ETH and 4812 Mh/s DCR (without modding) currently at 2600 Mh/s but 50/50 accepted and invalid share ratio so pool disconnects

use -asm 0

Here is my bat file

./ethdcrminer64 -epool us1.ethermine.org:4444 -ewal 0x95232B0E1a2dcE5AeDaA001C1135425afa2f306B.Eg1 -epsw x -gser 2 -wd 0 -tt 66 -fanmin 60 -dpool stratum+tcp://dcr.pool.mn:2255 -dwal hzavarce.eg1 -dpsw x -allpools 1


Tried -asm 0 but still same problem with bad DCR shares, I have 6 RX480 Sapphire with modded Bios

With 8.1v on Ubuntu 16.04 (Log from yesterday)

12:56:59:940   8d7fa700   ETH - Total Speed: 161.061 Mh/s, Total Shares: 64, Rejected: 0, Time: 00:29

12:56:59:940   8d7fa700   ETH: GPU0 26.821 Mh/s, GPU1 26.889 Mh/s, GPU2 26.802 Mh/s, GPU3 26.874 Mh/s, GPU4 26.855 Mh/s, GPU5 26.821 Mh/s

12:56:59:940   8d7fa700    DCR - Total Speed: 2415.912 Mh/s, Total Shares: 136, Rejected: 1

12:56:59:940   8d7fa700    DCR: GPU0 402.321 Mh/s, GPU1 403.329 Mh/s, GPU2 402.027 Mh/s, GPU3 403.105 Mh/s, GPU4 402.819 Mh/s, GPU5 402.311 Mh/s


If I only mine ETH I get 29.2 Mh/s

[nu1mlock]

Does anyone know if there's a reason for my GPU's not being fully utilized when mining?

For example: My two Fury Nitro's clockspeed is set to 1050MHz (default). However, they're only mining at about 970MHz.

However, if I undervolt them, they get close to default, being at around 1030MHz - 1040MHz.

At first I thought that it might've been because of the PSU because it's on the edge of being too little. I've got an EVGA SuperNova G2 750W. However, when I removed one of the cards, the one that is left is still doing the exact same thing so it's not that it doesn't get enough power.

I tested the cards with MSI Kombustor to stress test them but that works fine at 1050MHz even with no undervolting.

Any idea why the cards don't mine at full clock, but close to max if undervolted - even though they get enough power?

As a side note I should mention that I've got an i5 6600K so the CPU isn't limiting them either.

Thanks!

[Ursul0]

I run polaris cards heavily undervolted (850mv) and in order to get v9 asm stable looks like I need to up the voltage +10mv at least, especially Hynix with 1500 straps.

they are probably hitting their power limit.

That might be the case. Anyone else having speed issues with stock bios RX series?

yea look through the pages since the 9.0 release seem like RX's are suffering

my 2 rx480 arent very stable as yet i've still not found the best dcri value

While they may seem like they are suffering I did the math. I still made more money on 9 than 8 with my RX 480 dual mining. The increased performance from DCR was worth the fluctuating hashrate.

[jackbox]

My hashrate fluctuates and is slightly lower than with a solo miner (genoil) but the Pascal Coin I am mining in dual mode is more than making up the difference. I tried mining DCR but all shares were rejected. With Pascal Coin on Nano pool I have had no rejected shares and also no rejected shares for Eth also on Ethermine.org pool.

Hey guys, I am new to Ether mining and the cryptocurrency community but am looking forward to the experience! I just got my rig built and am trying to get connected to Nanopool to start mining. I have read and read and then read some more before getting into this. I have followed the instructions to the best of my knowledge but can't seem to get Claymore to operate properly. Below is the most recent log from trying to run Claymore along with my current setup below that. What am I missing and what do I need to fix to get this best running? I am sure it is something so simple and I have just over analyzed my issue. Any help is much appreciated and thank you in advance for your knowledge and insight!

Your wallet address is in the incorrect format. You need to put "0x" in front of it so your command string to start the miner should be as follows:

12:53:31:314   1908   args: -epool eth-us-east1.nanopool.org:9999 -ewal 0xb3995a07324ye6b0c8z61937fc36d430adcc6fa1 -epsw x -eworker -allpools 1

You can also add a worker ID and your email to be notified if your worker goes offline.

12:53:31:314   1908   args: -epool eth-us-east1.nanopool.org:9999 -ewal b3995a07324ye6b0c8z61937fc36d430adcc6fa1/WorkerID/youremail@domain.ext -epsw x -eworker -allpools 1

and sure your your bat file you use to start the miner has the following lines before the execute command

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

WOW...thanks SO much jackbox...I knew it had to be something so simple! That worked and shares are already being found!

ANN: In 2-3 days I will release new version with assembler kernels for ETH+SIA and ETH+PASCAL modes, with similar speedup as for DCR.

Thanks however can you also add this feature for people who mine with both ZEC and ETH with your miners.

If a rig has 6 GPUs say ( 280X,280X,280X, 480, 480, 480)

The 280X usually mine ZEC and the 480 usually mine ETH

However if someone runs ZEC with the first 3 GPUs (GPU0, GPU1, GPU2) and runs ETH with the rest ( GPU3, GPU4, GPU5)

Then the second program ETH-Miner will incorrectly label the GPUs. Instead of GPU3,GPU4, GPU5, they will start at GPU0,GPU1,GPU2 and it will read the temperatures from the first 3 cards and not the latter 3 and if GPU0 from ZEC overheats, then GPU0 and GPU3 will also throttle (using TTLI)

THis is hard to explain, let me know if you need photos.

Is there any reason to upgrade to 9.0 if you've got old GPUs? (280/290 etc)

Huge DCR performance boost on 290 when dual mining, you might be power limited though.

I've got a 5 GPU R9 290 Ref rig.. when I use dual mining with DCR.. my Eth mining goes from 31MHS to 24MHS... I've tried a lot of different -dcri settings.  Do you mind sharing your bat file?  Thanks!

Which is the best ethereum pool for Claymore, i use coinotron, but my hash rate fluctuates too much, and my ethereum count on coinotron is slow compared to gnoil for example. Is it normal, i do prefer Claymore is the best, but my minining rate is slo with it, maybe is the pool?

Thanks

Best Pools:

For <500Mhs is ethermine.org  can set the payout
For >500Mhs is ethpool.org cannot set the payout, but gives uncles occasionally

Good Luck!

Nothing special in my bat really, most likely your cards are throttling. Have you tried really low dcri? Monitor your core clocks when mining, are they steady at those clocks you set?

If not you need to do something to get power usage down.

Use "-gmap" option to manage list of temps/fans.

Does anyone know if there's a reason for my GPU's not being fully utilized when mining?

For example: My two Fury Nitro's clockspeed is set to 1050MHz (default). However, they're only mining at about 970MHz.

However, if I undervolt them, they get close to default, being at around 1030MHz - 1040MHz.

At first I thought that it might've been because of the PSU because it's on the edge of being too little. I've got an EVGA SuperNova G2 750W. However, when I removed one of the cards, the one that is left is still doing the exact same thing so it's not that it doesn't get enough power.

I tested the cards with MSI Kombustor to stress test them but that works fine at 1050MHz even with no undervolting.

Any idea why the cards don't mine at full clock, but close to max if undervolted - even though they get enough power?

As a side note I should mention that I've got an i5 6600K so the CPU isn't limiting them either.

Thanks!

Cards throttle due to power limit. Some activities take more power than others.  Dual mining is very power intensive. Cards used to just burn up when running programs such as Furmark, vendors started doing power limits to prevent damage.  Undervolting usually stops throttling like you have noticed.  You can also increase card power limit, at your own risk.
