Ethereum GPU mining?

[Hitman928]

Heads up to my fellow Ubuntu/*buntu users with AMD cards: there's no fglrx/catalyst for Ubuntu 16.04, Xenial Xerus, and it doesn't look like there will be. Just found this out when trying to put daily build of Xubuntu running off flash drive on a new R9 390 build, and couldn't get the fglrx-updates driver as I usually would through "Additional Drivers" or apt-get.

You should still be able to download them directly and generate for 16.04 though, have you tried that?

I know I probably could, but it was quick enough to format and use 15.10. Didn't want to bother in case there are any other issues with 16.04. I'm only using Ubuntu+AMD for mining (for a few months more), and my main desktop has an NVIDIA card.

I'm using 15.10 in most of mine, but I find there's some pretty terrible issues with clocking the cards. Often aticonfig won't let me set fan speeds or clocks on the non-primary cards, or even use --odgt to get the temps. Does anyone else have issues with this/.

 

[Hitman928]

Do you get an error message MrTeal?

 

[MrTeal]

Do you get an error message MrTeal?

Yeah, something along the lines of ERROR - Get temperature failed for Adapter 1 - AMD Radeon (TM) R9 380 Series

The PPLIB commands to the second card don't always report an error, they just don't do anything.

2 things:

Have you done:
sudo amdconfig --adapter=all --initial
sudo reboot

After a reboot, if that doesn't work do this:

Use vim/nano/emacs or whatever to edit /etc/init/gpu-manager.conf

You'll want to comment out the start on lines like so:
#start on (starting lightdm
# or starting kdm
# or starting xdm
# or starting lxdm)

then reboot. You may need to do step 1 again.

Let me know if this works.

I rerun initial after each change, but I'll try the commenting out when I get home. Thanks.

 

[MrTeal]

The manual editing of the file seemed to do the trick, thanks.

I also managed to get fan control working right. My understanding of the pplib commands was obviously flawed.

I was doing
aticonfig --pplib-cmd "set fanspeed 0 100"
aticonfig --pplib-cmd "set fanspeed 1 100"
etc
That would set the first fan on the first card to 100 though, then the second fan, etc.

What I needed to do was
env DISPLAY=:0.0 /usr/bin/aticonfig --pplib-cmd "set fanspeed 0 100"
env DISPLAY=:0.1 /usr/bin/aticonfig --pplib-cmd "set fanspeed 0 100"
etc

Much better now.

Man we really need a sub forum or new thread for mining and break out all the good info into easy to read steps.

Sent a PM to the Big Man Upstairs (Perknose) humbly requesting a Cryptocurrency forum. The greater technology (blockchains) and affected areas (finance/economics, politics, software, hardware, consumer tech/IoT, distributed computing, security, etc) is too broad to be limited to VC&G, and more technical and serious than being limited to the OT catch-all (where some prior cryptocurrency threads reside). And simply spinning off more threads in this forum would probably start to annoy the non-miners.

Bitcoin and Litecoin have already proved interest, and it's been a few years since Satoshi Nakamoto released his Bitcoin whitepaper, so it's pretty evident the underlying tech and discussions aren't evaporating into the ether () anytime soon.

Would have posted it to suggestion box, but that's a ghost town.
There are a lot of forums already, though, so it may or may not be approved by the greater administration (Administrati? :hmm: ) ...can't blame them, really, if that's the case.

EDIT: I think the forum should be called Cryptocurrencies and Blockchains (or Cryptocurrencies/Blockchains), as that would be the easiest common identifiers, though "Decentralized Platforms" would be the most inclusive and forward-looking moniker (but would probably include Bittorrent, too, and may overlap some in theory with Distributed Computing).

Question: I've poked around in this thread, on Google, and elsewhere, and I haven't seen much information about why Linux users are reliant on fglrx for Ethereum mining. Is the OpenCL implementation of the radeon/amdgpu driver completely hosed?

Has anyone used or heard anything about this PCIE riser?

[DrMrLordX]

Haven't used or heard of it, but you may not require a ground wire per card using a riser like that.

Thanks Crono,

I suspect if this thread keeps going, administration will have to put us somewhere

The names you suggested would work fine. We could have sub forums for the most popular crypto-coins to keep it all in one place.

And if Perknose is reading this, yes there are other forums specific to mining but we have a lot of members here with interest and experience, so wouldn't you rather keep us here even if only for the advertising revenue?

That's the style of risers I'm currently using in my Milkcrate miner. They work excellent, just don't put them in backwards

I ordered several more yesterday.

I'm not an electrician but I believe the units are grounded via the molex to sata plugs provided by your power supply.

Yeah I have a rig going with 4 of those. It's the preferred type of riser IMO.

Bought a couple from that seller (post 331), but on ebay. Working great.

On those adapters, are the 12V pins from the 1x PCIe card edge connector attached to the 16x along with the SATA input, or is the 12V to the PCIe 16x powered solely from the SATA power connector?

The riser is powered from the SATA/Molex connector.

 

[MrTeal]

The riser is powered from the SATA/Molex connector.

That's good, it simplifies dual supply wiring. Most of the ribbon based powered risers have the molex input in parallel with 1x slot, so if you use a separate supply it will back feed power into the MB.

Does 400w for the total system sound right for a 390x?

couldnt find your system specs but my single r9 390 non X (a sapphire nitro) pulls 330 watts at the wall on my killowatt meter. 5 fans, 4 drives, 3570k, 12 gigs ram. pulls ~31 mhs. 1090/1500, -75mv. bronze PSU (antec earthwatts 650).

mine is non X but I cant see that being 70 watts difference.

have you undervolted the gpu?

Just a harsh reminder of the difficulty curve. I expected this to happen but not so quickly.

Sorry to be the bringer of bad news.

How long do we have left before our earnings drop by 1/2 due to a doubling in difficulty?

During BTC days, the market value of the coin adjusted as difficulty increased and it became more scarce. Seems like that's not happening with Ether at all. The unfortunate part is that even as AMD increased shaders with Fury X, the output didn't proportionally increase over 290/290X/390/390X. That doesn't bode well for next gen cards when in the past as AMD GPUs got 40-50% faster, their BTC output also increased.

I am staying tight for not and most likely not buying any more cards until GP104/Polaris 10 launch and re-evaluating the market based on their output (MH/$ and MH/watt). Also, it's just a matter of time before we start seeing big price discounts on old inventory (380X->Fury X should all drop in price 1st week of June, if not earlier).
