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

..and did you measure the power-consumption on each GPU at such clock?

Nope. But I don't stake on those 7970: they are really hot for some reason comparing to any other my cards (7950, 390, 390X). Thermal interfaces were replaced, nothing helped. I bought them used and plan to sell as soon as I replace them by 390X (on order). Previous owner used them for hard gaming with SLI/CrossFire @1220 with original BIOS (they are BE, Boost Edition, and allow such OC). I just run them @ factory boost clock:

Undervolt by 100mV and enjoy -10 temps

It works on Windows. But I even asked here if someone managed to undervolt on Linux (w/o BIOS mod) and got no replies. I can reflash BIOS, and even did that. By default these 7970s have 1.256V max, and I patched in 1.100. It worked on Linux, crashed on miner start on Windows (did not use serialised init). With 1.150 they were stable. Still, I wish I find a way to undervolt them on Linux w/o BIOS mod, I don't believe there is no such tool, I just need to find it.

i mine at nanopool with 4.4 and 1 card, named "390" with a password of "x".  ive noticed that occasionally nanopool will switch to a worker called "x" for a few hours, then back to "390" IOW mixing up password and worker name.

its still the right eth addy so no worries but has anyone else seen this?

EDIT started looking through the logs with notepad++ and found "390" wasnt a good choice for a worker name when mining with one heh ill rename the worker to something else.

EDIT 2  ok now worker name is "Frodo" with "xyz" as password. should make log hunting easier.

EDIT 3 the .exe gets all info from config.txt and epool.txt. nothing on command line if that matters

Hello.
Great work Claymore.
But one question...
Version 4.1 works without problems for me and looks very stable. But 4.3 crash most times after hour (I was start using parameter -r 20  -gser 2 and -mport 3333 from this version) . And version 4.4 drops hashrate from 167MH to 33MH or less and give me this error:
server: bind failed with error: 10048, next attempt in 10sec...

Where can be problem ?

Thank you.

I can send all logs somewhere..

[markus124]

Seems like an easy to solve task but i can't get the alternative pools to work when the main pool is down.
This is the config i use in the dpool file.

POOL: stratum+tcp://dcr.suprnova.cc:9111 -dwal markus.markus -dpsw x
-eworker markus

POOL: stratum+tcp://yiimp.ccminer.org:4252 -dwal DskZM1YQeiqhWas2cVEHaRRabwZzQaJnc9G -dpsw x

and the epool config:

POOL: us1.ethpool.org:3333, -ewal 0x59c73395a50d79b2a675802581f34387a09aed** -epsw x

POOL: us1.ethermine.org:4444, WALLET: 0x59c73395a50d79b2a675802581f34387a09aed**
, PSW: x, WORKER: markus, ESM: 1, ALLPOOLS: 0

Today suprnova was down for a few min and i saw the claymore trying to connect the alternative pools and it didnt work. All red. What im doing wrong?

 thanks in advance

your ETH address... ends with "24" and the other ends with "25" ~ typo???

Yeah i changed the original eth and nova address just for here but it work good in the config.

Can someone post their suprnova and eth "alternative pool" configuration. Something that works . Btw im using windows 10 i dont know if that affects in something.  Thanks

Sure, but that's what I was asked for:

That is, it lists only 2 performance levels (0 and 1) and can change settings for them. But cards work actually at perf levels 2 and 3, and there is no way to alter settings. Someone wrote that he patched the tool to use perf levels above 1, but it did not change the voltage. It seems that BIOS mod is the only way to change voltages for 79xx cards (newer cards use version 6 of API and there is another utility for them that should work).

[fredeq]

Sounds like a patch is needed ineed.
Guess you have tried to change voltage with forcing `-P 3`, even if not listed by default?

Yeap, no luck.

Reflashed with patched BIOS, good results for now, yet have to see how stable they will be:

I'm having issues with undervolting, if I set the core voltage lower before starting the miner it crashes the whole system, if I do it after starting the miner it's solid until there's a disconnect/ reconnect for whatever reason, any workarounds for this? Maybe set a high power limit? Thanks.

[citronick]

Hi Claymore,

All my rigs are now with v4.4 and doing very well.

The CDM Manager is fantastic.

Can you consider these CDMM features for future versions?

1. Restart counter for each Rig/Miner (eg. how many times the rig has restarted - triggered -r switch)

2. Failover counter for each Rig/Miner (eg. how many time the rig has failover to backup ETH pool)

The features above, will be very useful for troubleshooting and ensuring mining operations are in tip-top condition.

Thanks

[drr0ss]

The DAG takes maybe 3 seconds to generate on the GPU in my SGMiner port - I'm assuming Claymore has similar performance.

Wolf0, were we can find your miner?
10x

Who said I released it?

@Ok Wolf0

Claymore, can you add truncate and log rotation of log file?
We can do this via task scheduler or cron, however is more comfortable miner to make this

going to be setting up an ubuntu box this weekend, it will have a 390 and 380, based on an old q6600 system. 850 watt seasonic.

which ubuntu? 14.04 lts seems to be the recommended.

any tips? i know just enough  *nix to make possibly better than average mistakes faster.

have you tried playing around with these switches:

-cclock   set target GPU core clock speed, in MHz. If not specified or zero, miner will not change current clock speed. You can also specify values for every card, for example "-cclock 1000,1050,1100,0".
   Unfortunately, AMD blocked underclocking for some reason, you can overclock only.

-mclock   set target GPU memory clock speed, in MHz. If not specified or zero, miner will not change current clock speed. You can also specify values for every card, for example "-mclock 1200,1250,1200,0".
   Unfortunately, AMD blocked underclocking for some reason, you can overclock only.

-powlim set power limit, from -50 to 50. If not specified, miner will not change power limit. You can also specify values for every card, for example "-powlim 20,-20,0,10".

@Claymore, is there a way to activate email notifications on f2pool? especially in epools.txt?

Thanks!

I could recommend trying GenEthOS distro: https://ethereum-mining.info/en/
It is ubuntu 14.04.4 LTS-based distro that includes many tools for ETH mining (proxies, miners, GPU tweakers and monitoring tools) and is free to use. Runs from USB stick (8-16GB) if you want it, or HDD/SSD. It does not contain CDM (since it is not an open source), but perfectly runs the binary. You need to tweak few files via ssh or using Webmin GUI. It also runs basic web rig monitoring UI that includes GPU temps, fans, frequencies and core voltages. The only disadvantage is that by default it uses Russian and most comments in files are in both English and Russian duplicated or mixed, you shoud change /etc/default/locale (or via web UI) to English if you like. Still, it runs very stable and unlike some other distros is free to download. I remember some other ETH mining distro that is sold on SSD using open source Linux, that's against GNU license.

Are you using a 290/290x/390/390x by any chance, they crash to a blank screen when undervolting? Maybe Nano, I've never used a Nano though.

I had the same issue. The problem with undervolting these chips using something like MSI AB is that the voltage adjustment is an offset and applied across all states(7 different DPMs). While I found all my cards would happily run with a -100mv adjustment at full load(DPM7), even at 1050MHz core, as soon as they went idle they would crash.

Why? This is because the offset is applied to the other DPM states of the core across the frequency range, and presumably the core isn't stable at these other states with the -100mv offset also applied.

I fixed the problem though! I went here http://www.overclock.net/t/1561372/hawaii-bios-editing-290-290x-295x2-390-390x and read about editing the BIOS.

I ended up setting custom voltages and frequencies for the 8 different states so I no longer need to set a negative offset in any software. Now I can run them at full load, at 1050MHz core, stable, with less than 1.1v. And they don't crash as soon as the miner stops running, because voltages for the other states are still high enough for stable operation.

I can provide an example BIOS if you want? I did it for my ASUS, XFX and 2 MSI 290x cards. Fixed the issue for all of them.

[Claymore]

@Claymore, is there a way to activate email notifications on f2pool? especially in epools.txt?

Thanks!

You should always read pool help because it is always pool-related. For f2pool the only info I found is:
....
How can I receive notification in case of miner failure?
Please check the mining notification service provided by BTCKan.
....

That is all that they can say.

[Claymore]

Well, when miner fails I want to see entire log, not some part only.

Ok, I'll add it in my todo list.
