1  Alternate cryptocurrencies / Mining (Altcoins) / Re: RX480 gpu0 reports 4Mh/s only on linux on: September 13, 2017, 09:21:03 PM
I just ran into this. For me, the solution was to use:

Code:
GPU_FORCE_64BIT_PTR=1

Hope this helps someone.

I've created a repo of sgminer-gm configurations. Right now it only has XMR configs for R9 cards, but I'm hoping for some contributions from the community to increase coverage.

You can open an issue or create a PR with your config and hardware specs.

Question for the Ubuntu team:

Can i install the server edition (no X, etc.) and then add all the drivers - SDK ?

Or do i need the full installation ?

Thanks


Yes, a server install is fine.

Anyone know how to install ADL on Ubuntu 16.04 such that the library is found?

Code:

linux guys,

what OS/drivers are you using to mine? Actually, I've mined sgminer/claymore earlier, so, I'm still standing on f21 with fglrx 15.12. And now, using this miner I've got:
Code:
[GPU 0] T=-1C A=-1% sols=16.957
[GPU 1] T=-1C A=-1% sols=16.936
[GPU 2] T=-1C A=-1% sols=16.010
(ST/INV/DUP): 4317x 0ch(8/0/0)
per 3 x R9 NANO cards miner (small one closed chassis that I've got few). But reading the forum I'm coming to think that the mining speed seems is lower than usually taken with amdgpu-pro drivers.


I'm using Ubuntu 16.04 with amdgpu-pro 16.30.3.

Just adding my results. Ubuntu 16.04, amdgpu-pro, 0.2.4 silentarmy.

Sapphire R9 380 - sols = 29
Sapphire R9 390 - sols = 38
Sapphire R9 390x - sols = 42

eXtremal, payouts aren't working.

The one page in the admin area where i shows dropbear port 22, that's what allows putty to connect right so if I changed hat to say 2013 I would use 2013 in the port box on putty to connect via ssh ?
So, anyone ?

Yes, that's correct. It changes /etc/config/dropbear and restarts.

config dropbear
   option PasswordAuth 'on'
   option RootPasswordAuth 'on'
   option Port         '2013'

I have 2 S3s that are now over-clocked. I'm using a Corsair RM850 to power both, with 4 dual PCI-E cables. I didn't have any luck getting them to run stable at 250Mhz, so I backed off to 237.5Mhz.

Results after 1 day:





Both miners have settled in to an average GH/s of ~478, but there's a lot of variance as you can see by the graph. Still, very pleased with the results and the lack of hardware errors.

Hello to all you p2pool node operators. I've forked p2pool, added an adaptive difficulty patch and exposed some additional bitcoind RPC calls. You might want to check it out:

https://github.com/jramos/p2pool

I've also added an updated web interface. It provides:

  • Audio and text notifications for new shares and blocks (on most modern browsers)
  • Automatic conversion of BTC to USD
  • Integration with Blockchain.info APIs
  • Detailed information about each share, block and transaction
  • All the graphs you know and love
