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

[adamvp]

bad issue with SSH linux strikes again

To remind: When I want to end/break/kill screen session miner don't want to hear me
Today I noticed that then GPU hangs and miner restart info..
In previous versions everything was OK...

armyman your PSU isn't enough. You shouldn't run a PSU at more than 80% of it's rating. rx480's can pull up to about 225 watts each, which is 1,350 watts. You have up to another 150-200 watts for the system also, excluding the vid cards. So you are over 1500 watts on a 1200 watt PSU. Of course it will not be stable. A 1600 watt PSU will run 6 480's and the system....just. It is still pushing the limit a bit much when you factor in the 80% rule....but it will run stable.

480 draws ~165w stock (this is by card, not at the wall).  If you don't change power limit, the cards would draw ~ 1000w, and other system parts maybe 50-100, so PSU shouldn't be overloaded, but is higher than you would want for 24x7 operation, and may be slightly less stable near full load.  You can undervolt to save ~20-30w per card.

Claymore,
i got many Share Accepted and SHARE FOUND msg when i use dagger hashimoto.
i didnt get so many msg if using ethpool.

is this normal?

ethpool is solo, right?

I mine at ethpool and I can say that its not outright "solo" - however behaves like solo.

The devs call it "predictable solo mining"

if you have a few hundred MHs or more, ethpool IMHO is best pool to be, as you get 5++ coins per every round.

How can I reproduce this issue?

I thought Claymore said that he would fix the limit in next release.... so your 19 x GPUs may not work yet with current release.

You should take some pictures to share with us - its an amazing project

It seems now AMD drivers have problems because OpenCL does not work, miner asks OpenCL about AMD platform and it returns nothing. So the reason is in drivers.

yep
I'm trying to install a new system
thanks

Claymore,

Will it help if Ubuntu 14 instead of 16.

Seems v16 doesnt have the complete AMD drivers.

I don't know if it was any  backend changes,  but V 7.1 introduce colors.  There is no big problem for me now, because I have only one linux rig, but if I will make more in the future.. or you could add "on the run" pool management in any future realease

Oh yes, live pool switch please

another issue with Linux version, from few days it constantly switching SIA pools every 30-40minutes..
Windows version is ok, even if I revert rigs :S

Code:

SC: http error #28.
 SC: Failed to check work on pool, retry in 10 sec..

This error code means "operation timeout".
I can say again and again: don't use Linux if you can use Windows! Most problems are related not to miner but to Linux itself and I have to find workarounds all the time.

The miner doesnt start - this isnt a problem by psu power. If psu power fails, the system shuts down.

It is the PSU, during start up and DAG process the system draws more power. His ETH process is starting, but stops. Easy way to find out.....disable all the cards but one in the command line options, then enable them one at a time until the crashing starts again

I have tried as you said and it did work!

Unfortunately I have just been able to modify the setup from my phone through remote control, but apparently with one card only it was starting mining....I have noticed that it the beginning the hashing speed was 0, is that normal?

Which software would you suggest to undervolt/light overclocking? Wattman? Is it possible to download it somewhere?

Thanks

I am going to mirror the sentiment that intensity needs to be reduced during dag generation. Previous memory OCs were stable, now with the latest epoc they are no longer stable during generation. Please add the ability to reduce intensity on the miner during DAG generation.

I can generate the dag without a memory OC just fine then OC the memory after the miner is running and it works. If I try to generate the DAG while the memory OC is in place the GPUs crash.

Ok, in next update I'll add "-lidag" option. New version will be available in 1-2 days.

Appreciate it dude.

purpose of repost 1 hour later ?

He posted between my original post and when I posted again. I reposted as he more then likely missed the original post in the sea of other posts. I thought it was very pertinent information as someone else mentioned having a similar problem. Having discussed a similar option with Genoil, I think it would be prudent in Claymores miner too.

Although thanks for policing. Your service is invaluable to this thread.

Weird to see a developer who isn't singing praises about Nix and wearing his Nix badge of honor around. Almost like there is more to the OS then just one is better then the other.

Yes that is normal, until the DAGs finish..

Wattman is part of the driver.  Just go to Radeon settings, Global Settings.  There is a tool someone made called WattTool, I haven't used it though, wattman works just fine.

It comes with AMD drivers. IIRC, you go to AMD Settings | Gaming | Global Settings.

Anyway, I hate those fancy messy gamer apps. WattTool is much faster and easier.
