Claymore’s ZCash AMD GPU miner v10.0 and Optiminer Update


    Quick update for ZCash, v10.0 is out.  Small speed upgrade, but more speed is on the way this week.  You can now select your algorithm with -a.

Latest version v10.0:

– improved speed for most cards, up to 8% (depends on card model). About 340H/s on stock 390X, 255H/s on stock RX480, 320H/x on stock Nano.
– added “-a” option to select best algorithm implementation for your GPU.

    Optiminer v1.3.0 is now faster for linux AMD users.  Remember speeds include the fee, so what you see is what you get.

Expected speed (stock card, linux):

  • Nano: 390 S/s
  • R9 290: 285 S/s
  • RX 480: 260 S/s

Claymore CryptoNote miner and EWBF’S ZCash CUDA update


    For the Nvidia users out there, remember you can use EWBF’s CUDA ZCash miner.  Very decent speeds.

EWBF’s Zcash cuda miner.
Expected speeds 380 – 400 sols/s gtx1070. 260 – 270 gtx1060. Stock settings.
Writen for pascal gpus but works on cards with at least 1Gb memory, and Compute Capability 2 and higher.
Miner contain dev fee 2%.

    For the XMR update, Claymore has updated the CryptoNote miner, with a fee reduction to 2% if using SSL.  The speeds are the same, but he has added all the usual features that were lacking in the XMR miner.  Next update may have a speed increase.

Current version: 9.7:

– reduced devfee, it’s 2% now if you use secure SSL/TLS connection, currently miningpoolhub pool supports encrypted connections, see Readme for samples.
– added “allpools” option, use it if your pool requires Username.Worker instead of wallet address, or if you mine some fork of Monero.
– now all options can be stored in “config.txt” file.
– changed format of “pools.txt”, now you can specify own settings for every failover pool. Since format was changed, failover pools file was renamed to “epools.txt”.
– now “r” key reloads failover pools file, “s” shows current statistics, with digit keys you can disable/enable GPUs.
– improved support for EthMan, now all commands are supported.
– now remote management is working in read-only mode by default.
– added SSL/TLS encryption support for better security, see “-o” option description in Readme file for details.
– improved “-tt” and “-r” options.
– added “-fanmin”, “-fanmax”, “-tstop”, “-powlim”, “-cvddc”, “-mvddc” options.
– added HTTP support for remote port.
– added “-retrydelay” option.
– added “-ftime” option.
– a lot of minor improvements.

Bitcoin hits 1000 $ USD


    News from the new year !  Bitcoin is now worth 1000 $.  With further capital restrictions in China due to capital flight and a continued devaluation of the Yuan, Bitcoin will be increasing in popularity in 2017.  And when we have increasing popularity, we have increased price.  Lets just hope something happens to resolve the matter of blocks being full, which is increasingly becoming a brake to bitcoin adoption.

Sapphire Nitro R9 Fury Review


    Happy new year everyone !  A new year brings a new GPU to Cryptominingtalk.  Today, we review the wonderful R9 Fury from Sapphire.

    These are on sale pretty often with the new generation coming out in a few months, we picked one up for 340$ + tax and shipping (CAD, newegg.ca here, referral link).  Out of the box, we get 31.5mhs on ETH and 380-400 sol/s on ZCash.  At 55c and fans running at 48%, this GPU is silent and cool.  You can under-volt it way past -100mv for optimal performance, and overclock the core up to 1200mhz.

    We couldn’t let this GPU just mine all day, so it went into the main gaming rig.  Due to high demand from gaming, you can’t under-clock it as much if you want 100% stability.  But so far at -66mv stable and overclocked to 1100mhz, we have a power consumption right at 210w.  You can bring this down to around 150w.

   This GPU features a dual bios button, triple fan cooling, and amazing gaming performance as a plus.  Its simply beautiful.  If ZCash stays relevant, this is a no-brainer, 360 sol/s for 150watts makes the R9 Fury a great choice, that is, until VEGA comes out.

Just released, Claymore’s ZCash GPU miner v9.3


    We have a minor update for the ZCash miner from Claymore.  Here are the details.

Latest version v9.3:

– improved stability and compatibility with various drivers.
– slightly improved mining speed for some cards (1-2%). About 340H/s on stock 390X.
– fixed issue in Linux version with GPU SEGFAULT and high CPU load.
– added support for round robin DNS.
– some bug fixes and minor improvements.

    So far we can see a nice improvement on R9 390s (and 290s) for about 5%, bringing hashrate to a comfortable 330-335 sol/s.  Some users report dropping hashrates for 280x and Rx470/480 series, some report improvements, so just download it and check it out yourself !

Monero Mining Guide


    If you have AMD GPU’s, you will usually be mining Ethereum or Zcash.  But you can also mine Monero !  Indeed XMR is a great choice for mining, as it uses 10 to 15% less power than ETH.  Here is how to get started.

    First off, you will need a miner.  Of course as per usual Claymore offers a good product, but it comes with a 2.5% fee.  It is the Claymore Cryptonote GPU miner.  There is also Wolf’s XMR GPU miner, and Sgminer-GM.  Wolf’s may be fastest for Polaris models.  Try with 2 threads, 4 workload and 504 rawintensity

    Once installed, setup is with a .bat file as usual.  Note :  for XMR, you can mine directly to an exchange, but you must put your “payment ID” after your wallet address, and not all pools allow it.  Plus some pools have really high minimum withdrawals, so you may be better off mining to a web Monero light wallet and then transfer funds from there.

    For pools, there are many, one of the biggest is Dwarfpool, which you can find here.  Instructions to connect are simple and straightforward (2% fee).  There is also MoneroHash.com and MoneroPool.com just to name a few.

    XMR is most profitable with the Rx470, as it can hash out almost 800 hashes, almost as much as an Rx480.  Don’t forget you can also CPU mine XMR, see the claymore page for a link to the miner.  You can also CPU mine with this awesome new miner, XMR-Stak.
