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

[big_daddy]

MR Bigdaddy

Try and read some of the stuff in the previous pages you might just learn something more..


Your problem is that you have overclocked the cards too much.
leave the core clock frequency the same
change only the memory by adding only 300 mhz not more unless you have cards with samsung memory which can take upto 700mhz safely unless you dont win the silicon lotterry that is too.....

but I am using 1150/2050 on my msi 570 8 GB (Micron mem), getting only 28,5, with compute mode & last drivers
what core clock are you suggesting me?

Is the next version due soon?
Claymore seems to be not around as much these days?

he is super rich now and planning to retire..

1070 in stock v 11.8 how fast?

[hugomenezes]

I dont know why my Claymore i only get 22mh/s. I try all steps and still the same.
When i try change the GPU and MEM frenquency the mh/s still the same. Its strange!

Hi all,
I need some help to resolve a problem on my Rig.
My Specs is:
Motherboard: ASUS B250 Miner Expert with lastest bios
RAM: 4GB
HDD:320GB
CPU: G4400
VGA: MSI RX580 Armor 8GB + Gigabyte RX580 Gaming 8GB
PSU: 2000W
Miner: Claymore 11.8
OS: Windows 10 Pro

I had Windows 10 with all updates, the drivers all updated and my problem is the mh/s speed, i only get 22mh/s i try to put diferent clocks speed on GPU and RAM but the result its the same   22mh/s.
I build other RIG with the same hardware and i get 30mh/s on RX580 with clocks GPU 1250Mhz 0.950v RAM 2150Mhz 0.950v.

Anyone had this problem?
Sry for my poor english.

Regards

Did you switch your gpu workload from graphics to compute?
In Claymore 11.6 or newer you can: press "y" key to turn on "Compute Mode" in AMD drivers for all cards
That could be the problem.

Hi guys
anybody know what is going on on ethermine ETC pool

its 3 different deposit addresses

every day this happens two times

Hi, I get ETC, sometimes my rig reboots, and Claymor's log comes to an end with the line NULNULNUL... Sometimes one hour, and sometimes works and 30, I can't understand in what the reason. Somebody knows that he means if the ravine comes to an end with NULNULNUL...

Have you tried to re-download claymore?
Are you using the latest version? Maybe try another version and check if it gives you the same error...
Have you checked if you are using the right drivers?

everybody has same problem - just go check random address on etc ethermine org pool
cant understand this also  

mining ETH is no problem
mining ETC is problem with same tools

looks like some kind of attack in ETC

I been having problems with the ETC pool there too. I mine ETH just fine but when I switch to ETC it gives me the same problems.

[nikdd]

Why I cannot use Nvidia GTX 970 cards at full speed (18-22mh) instead of 3-6mh? I was tried so many solutions. I tested on Win7 and Simplemining ubuntu editions. In rare cases on win7 sometimes cards start mining at 17-18mh but in short time speed degrades to 3-4mh. Thank You in advance.

Remove "-minspeed" option

[UnknownTraders]

GPU hangs are usually due to running them faster than what the manufacturer has approved, principally on the memory or too much undervolt for that card. What may help is draining all the power from the condenser which also helps reset the GPU's and extenders after a crash. Switch off the gear, cut off the power to the power supply unit via the switch on the back and press the power button to drain all the power. Then wait about two minutes before turning it back on.

[Jeeperz74]

Looks like my problems mining ETC have gone away. It must of been a pool problem and the miner is running smoothly now.

[bigdaddymccarron]

@bigdaddymccarron, could it be your swap file is not big enough for the DAG files?  I'm no expert on Ubuntu, but sometimes we overlook the simplest things.

I will check that, I saw something the other day that indicated it should be 22 gb.

[DireWolfM14]

A reliable source recommends 2.6gb per card, plus another 10 or 12.

[skyline_king]

I want to know I have 2 GPU GPU0 1060 3gb and GPU1 1070ti
want to mine with GPU1 only and leave the GPU0 Idle
should i add -di 1 to your bat file (same line as the rest)

Claymore

Users are still reporting random crashes in -esm 3 mode.

This may happen in 2-3 hours hours, few days or even not happen at all.

Typical description looks like "I've connected my farm there, and got my Claymore's miner crashed few hours later. So I switched to another pool".

There is no such problem with -esm 1 mode, as well as no issues with another software running in EthereumStratum mode. Ethminer is rock stable, for example... Though, on the other hand, it has some hardware compatibility issues.

[ermis1975]

I have 2 1070 cards. I want to know the best claymore settings for mining with them.

[MaxMidnite]

NOTE:
If you use old version of the miner (less than 10.2) and mine ETH or ETC - please upgrade and use v10.2 or higher. Old versions don't support DAG epoch higher than #199, this value can be lower if you use non-zero "-eres" option value (it is "2" by default).
See v10.2 description in "History.txt" for details.
