Update for Claymore’s XMR miner

    Short post for Claymore’s new XMR miner, which has been updated to v10.2.  Although it features an improvement over his previous version (including nicehash support), it is still better on some GPU’s to use SGminer or XMR-Stak-AMD.  We will be waiting for his V11 update, which should bring more speed improvements and more bug fixes.  It is, however, the easiest software to use for new users.  Check it out here.

VEGA RX 56 Review

    Welcome to the future.  Well, a little late, but VEGA RX 56 is here.  Turns out for the most part the future isn’t so great 🙁  But fear not, there is hope.  Best profitability is with Monero, so here is our review of AMD VEGA RX 56 on XMR.

    First off all, you need the AMD blockchain beta drivers (always use DDU).  Once you have done that, you can stick with wattman for now.  Make sure crossfire is disabled, and enable HBCC (your system needs 16g of ram…usually).  You can play with the settings to see what gives you the best hashrate and the least watts, but here is what we found to be quite acceptable.

  • Frequency all the way down, -30%
  • Memory to 945 (see what is stable)
  • Power limit -21% (see what is stable)
  • Fans, fans, fans.  Must be around 3500rpm at all times, but check your VRM temps to see.  Core temp is useless.  Hashrate will fall if the memory gets too hot.

    Now you can run XMR-STAK-AMD, (well after editing the config file) and see your results.  Your config file is pretty straightforward.  You need to set gpu threads to the number of gpu’s * threads per gpu.  In our case, that is 2 threads per GPU.  It looks like this for one GPU:

  • { “index” : 0, “intensity” : 2016, “worksize” : 8, “affine_to_cpu” : false },
    { “index” : 0, “intensity” : 1600, “worksize” : 8, “affine_to_cpu” : false },

    We get 3800hs for 2 VEGAs, 400watts from the wall.  It is possible to get better results power wise using a registry mod.  You can check it out on youtube here (at your own risk).  A big thanks to Hellae and rednoW on bitcointalk VEGA thread.

Update for Claymore ETH dual miner

    Claymore has updated his ETH Dual Miner to V10.0.  Updated features include ASM mode for LBRY, seriously increasing hashrate for dual mining LBRY (AMD only).  Main change is also semi-fixed voltage and clock control by the software with the new blockchain compute drivers from AMD.  Check it out here !

– added assembler kernels for ETH+LBC mining mode (AMD cards only), major speedup for LBC.
– about 1% ETH speedup for Vega cards.
– fixed issues with voltage/clocks management for latest AMD blockchain drivers (not completely).
– new GPU sorting method for NVIDIA cards. Now GPUs are sorted by physical bus index (it matches AfterBurner list of GPUs).
– for ETH+LBC mining mode maximal “dcri” value is 1000 now.
– added “-platform” option.
– added “ESTALE” option support in failover file epools.txt (see “-estale” option for details).
– several minor bug fixes and improvements.

DeepOnion and airdrops

    We don’t usually talk about specific coins (we never do actually), unless there is mining software or hardware news related to it.  But after getting questions and emails, I’d like to talk about things new people can do to get started in cryptocurrency, other than mining.  In fact, airdrops are a great way to make a little money, which you can use to upgrade your mining operations.

    DeepOnion is one of such airdrops, where you can find on the bitcointalk forum, announcements section.  Usually, all you need to do is download the wallet of the coin, and then sign up for the airdrop.  Be careful and always install the wallet a separate machine, in case there is malware associated with it.  Always read other users reviews too.  Sometimes the DEVs ask you to promote their coin through various means, such as reddit or twitter.  In any case you will get free coins which may have some value later.  There are also coins like Lumens, Byteball, Bitcoin Cash, who have airdrops based on your bitcoin balance at a specific time.  You simply sign a private message from your wallet (easy to do with electrum) proving you own the bitcoin address, and they send you the free airdrop coins.

    DeepOnion is the most popular airdrop right now on Bitcointalk, but it requires the users to promote the coin through a signature campaign (that is like an ad you place in your signature on bitcointalk).  There are strict requirements to weed off spam and spammers, but if you qualify, go sign up !  There are 40 weeks total of airdrops and this is by far the most valuable airdrop to be in.  Check out new coins here, and check out DeepOnion Airdrop here.  Good luck getting your free coins and happy mining.

Ethereum Official DAG fix

It is possible to fix your AMD RX470/480/570/580 GPU’s from losing speed every single Epoch if they are mining Ethereum, as the DAG file gets bigger and bigger.  A new official driver beta release permits this, and it works quite well.  The procedure is as follows:

  • Use the latest DDU version to remove your drivers in safe mode
  • Install the New AMD Drivers (beta for blockchain compute)
  • Install the latest Beta MSI afterburner v.16 from guru3d

You may notice a change in power consumption, and you can adjust your voltage or clocks to compensate.  A 6 GPU rig will gain about 10mhs !

SIGT Skunk algo miner

    We haven’t talked about Signatum or the Skunk algo yet, but it is the latest coin that has wind in its sail.  There are many miners out there, but there is a recent update by tpruvot from yiimp and it is the fastest.  You can check out his github page here.  Expect 50-55mhs on a 1080ti.
