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

[Claymore]

About low hashrates in dual mode - it seems I need to combine some of my messages into one and add some more comments about ETH+LBC mode.

1. AMD cards always handle dual mode better than NVidia. Especially 290(X)/390(X) cards, they are the best. RX480 is good too. Other cards are not so good in dual mode.
2. Lbry is not so good for dual mode as Sia or Decred, it takes too much GPU time, therefore ETH suffers. So only powerful cards are good in ETH+LBC mode. Do not use it on 280, 270, 7xxx, etc. On these cards ETH+DCR or ETH+SIA is better.
3. My test rig: 6x390, stock clocks, gives 172MH/s ETH in ETH-only mode.
In ETH+LBC mode, "-dcri 16", it gives 167MH/s ETH + 167MH/s LBC.
If you have 290/390 cards and see big drop on ETH even on "-dcri 16", make sure you use 15.12 drivers.
So I see -5MH/s ETH but +167MH/S Lbry, i.e. dual mining is working. Unfortunately, there is no way to get 0% drop on ETH if you mine ETH+LBC. Why? See item #2.
4. Why I added ETH+LBC if it causes ETH hashrate drop? Because this mode is good anyway for fast cards like 290/390/480, you get small ETH drop but good LBC speed.
5. Why I added ETH+LBC if ETH+LBC has less profit than LBC-only mining? Because in future ETH+LBC can have more profit than LBC-only.

Claymore, thanks for adding more and more altcoins, even thou i can't do dual mining LBC because i have 380's.
Anyway, thanks

I'm running 3x XFX Radeon RX 480 GTR Black and 1x XFX Radeon RX 480 GTR on one Rig using the latest Crimson driver and claymore's 6.3.
The hash rate per card is approx. 25.5-26.5 with some slight overclocking on the memory.

So far the system runs more or less stable. What difference would a switch to crimson 15.12 make and is it even possible/recommended with a rx 480? I've read they improved the energy consumption significantly with the latest version.

Also, has anyone been able to achieve higher hash rates with the 480s using claymore than what I got? If so, how?

I have a RIG with 3 GPU RX470 and 2 GPU HD7970,
Is it possible use 2 istance on the same RIG in this way:

- 1 on 3 GPU RX470 ETC+SC
- 1 on 2 GPU HD7970 ETC+LBC

Thanks

Hi,

Using v7.0 under linux as of today, but getting seg fault on one rig. Tried older versions (that i know used to work), same.

What could be wrong ? Faulty GPU ? Would be weird as they mine xmr fine usinf wolf's amd gpu miner.

Other useful info : Ubuntu 15.10, GPU are a mix of R9 280x and HD 7970

Any help would be appreciated.

Thanks,

Khad

The best are Fury and Nano (29.6 eth + 1186 sc)

290x has only 29 eth + 586 sc

but Nvidia more profitable on LBRY (1070 get 312 mh, Fury get 252 mh only)

Unfortunately, there is no way to get 0% drop on ETH if you mine ETH+LBC. Why? See item #2.

Fury not drop on ETH at dcri 30

Getting exactly what you are Claymore on my 390 sets.  167 167 with DCRI at 16

Your RX 480s would not be useable anymore.  
(supported from 16.6.2 on AFAIK)

Also, has anyone been able to achieve higher hash rates with the 480s using claymore than what I got? If so, how?

Yes. At least 26.6 Mhash/s ETC + 465 Mhash/s SC is possible on a (cheap and not so great) XFX RX 480 XXX without BIOS mod. More would be possible if the memory was not that picky.
How? Simply more undervolt, more overclock...

@Claymore

Is it possible on a sigle RIG with different GPU (I have RX470 and HD7970) run 2 different processes 1 for RX470 that mine ETC+LSB and another for HD7970 that mine ETC+SC ?

thanks

Yes, create two config files (or use two folders), specify "-mport 0" to disable remote management (or use different ports), use "-di" option to select cards in every miner instance, that is all. However, often it's a bad idea to mix cards of different generations since some of them may work slowly because driver is optimized for some one generation usually. You can solve it by copying appropriate OpenCL driver files (amdocl64, amd_opencl64.dll) to the folder with miner, but I'm not experienced in such things (last time I did it ages ago), you can search on this forum for details.

Anyone dual mining with a GTX 1060? What kind of speeds are you seeing for ETH + SIA?

GTX 1060 3GB Zotec ZT-P10610A-10L Samsung memory
OC: core none uses boost by default temp set to 85 Celsius, default is 83 Celsius; fan auto; memory +946
ETH only 22.3 MH/s
EXP +Sia 20.9 MH/s + SIA 418 MH/s DCRI set to 90
EXP + SIA 22.1 MH/s + SIA 218 MH/s DCRI set to 30

Thanks for sharing, not many people using these cards.

[joaocha]

@claymore It is possible to add a remote management from webinterface or from your remote app, where you can change dcri , turn mining on and off, and change settings on the go?

Is 15.12 still the driver to use?  If so, where is a good place to download it?  It looks like AMD removed it from their list of downloads.

AMD page - manually select driver - (select OS and card) - "download previous drivers & software" on the right

Of course useless for newer gen. RX series...

So does 15.12 NOT work with a RX470?

What is the most stable driver version for a RX470 card then? I seem to get that my miner stops mining and says there is an issue with the nanopool.org pool. Sometimes it would just quit.

I have a Powercolor Red Devil RX470 4GB

SOmetimes it runs for 6-8 hours just fine, then other times it would just stop.

Thanks for any help!

Dear Claymore,

Would it be possible to implement monero (CryptoNote) into the dualminer as well? I know, that you already have made another xmr miner, but to have such a profitable coin implemented would be really good. What do you think about it?
Actually, I am using your linux 7.0 build running on my amd rigs configured to mine eth+lbc. And for 5 x R9 NANO the results: ETH 120MH/s + LBC 200MH/s.

I use 16.8.3.  They are stable though the Red Devil cards don't seem to like undervolting, at all, so there they throttle ~1150MHz, secondary coin goes a little slower.  You can increase power limit though.  If there is an issue with the pool, that shouldn't affect miner, I use nanopool and never had a crash.  You can set up backup pools if you want (see OP).

15.12 does not work on any Polaris card, they need like 16.8.x or newer, RX 470 needs like 16.8.2 or 16.8.3.  15.12 is recommended for the 300, 200, 7000 series. Perhaps OP can be updated to clarify?

@claymore It is possible to add a remote management from webinterface or from your remote app, where you can change dcri , turn mining on and off, and change settings on the go?

If you use the config files you can change all settings on the go.

Right click and "edit config" on the rig you want to change. You can then edit settings like -dcri -tt etc.  Then save changes. Then right click and "restart miner" so the changes take effect.

yr welcome I wanted to get RX 470's as the ref design was supposed to be around $150 but no ref design @ launch so the price is garbage and the 1060's slap the RX 480's and RX 470's around in other algo's meaning you'll have better longevity than AMD for the moment imo

as per my understanding.... ETH and XMR are both using memory intensive algorithms (Ethash and Cryptonight) - so ETH + XMR maybe a bad idea. However XMR + DCR/SIA/LBRY combo like CDM is more realistic. In the XMR thread, Claymore already said that there is no plans for 2nd coin for XMR.

As it does not work with the 480 I don't think it will work with the (later) 470. I ordered one for testing today...

ATM I use 16.7.3 on Windows 8.1 64bit which is stable for at least days. The latest driver version two of two times made trouble with mixed multi rigs. (but this could be random, did not investigate further)
