Boxing Day is upon us !


The are many pretty decent deals on Rx 470s and Rx 480s, but you really should go out and look for them yourselves !  A good place to start is Build a PC sales, and Build a PC sales Canada on reddit !

A notable deal however, is the Sapphire Nitro R9 Fury, (click to go to the product page, referral link) which is at 400$-60$+shipping over at newegg.ca for Canadian shoppers.  Plus if you pay with Masterpass and use the coupon code MPBOX25, you get 25$ off !  We’ll have a review of that GPU soon, so stay tuned !

 

Claymore’s ZCash Miner v9.2 released !


    The latest version of Claymore’s ZCash (ZEC) miner is out (v9.2) !  Hashrates have improved a bit.  We are talking about up to 5 to 10% increase in hashrate on top of the V9.1 update.

    We can report the following speeds:

  • Rx470: 208 sol/s
  • Rx480: 245 sol/s
  • R9 380: 165 sol/s
  • R9 390:  320sol/s

From Claymore:

Latest version v9.2:

– improved speed for some cards up to 7% (depends on card model). About 330H/s on stock 390X, 235H/s on stock RX480, 300H/x on stock Nano.
– several bug fixes and minor improvements.

    This update reduces speed on the 280x, so stay with the v9.1.  In the future Claymore will auto detect the proper algorithm.  This pushed ZCash back in profitability compared to ETH for GPU crypto miners.

    On another note, Boxing day is almost upon us so stay tuned for great deals !

New PandaMiner GPU kit


***Remember, No pre-orders***

    Pandaminer has come out with a new ASIC-style (not an asic) GPU miner.  You can mine anything you would on windows, runs with claymore’s software too.  Basically, its a mini computer, with 8 Rx480s (probably MXM-mobile), apparently 8gb memory too.  The advantage is the server rack configuration, which enables easy large scale development.

    So far its on pre-sale, so do not buy it.  Its a bit cheaper to build on your own (we recommend you stick to building rigs), plus you can resale your GPU’s, whereas this miner can only be resold for mining.  You can follow the bitcointalk thread here.  It seems nicehash miner does not work on this machine.

New ZCash crypto mining software update


    Its time to update your rigs again, we have updates !  First off, a few minutes ago Claymore’s ZEC AMD GPU miner has been updated to v9.0.

***v9.1 now available.  Dev Fee reduced to 2% if using SSL connection and added stability***

    Here are the details:

Latest version v9.0:

– improved speed by 3-20% (depends on card model). About 310H/s on stock 390X, 220H/s on stock RX480, 295H/x on stock Nano.
– added “-i 7” and “-i 8” values, about 1% speedup, but can be unstable in some cases.
– added SSL/TLS encryption support for better security, see “-zpool” option description in Readme file for details.
– added “License.txt” file that contains the License Agreement.
– added “-v” option.
– several bug fixes and minor improvements.
– EthMan: improved saving options.

    So far we can say that for Rx470/480 models you will see an 15 to 20% increase in hashrate.  For a 390, a 5% increase, a 380 a 10-15% increase and a 280x a 4-5% increase.  We’ll take what we can get, but we are hitting the maximum as far as optimization for zec goes.  Fortunately, there are other developments in the works, and it may be possible to hit 300sol/s with a Rx470/480 in the future, so stay updated !

   SilentArmy (by MRB, who won 10k$ in the open source contest for ZEC) is also being updated.  This is great news for the open source community.  V6 should be out in the near future.  User Zawawa is also working on a silentarmy fork that looks promising.  Finally, user NerdRalph said he will probably take a look at ZEC to try to improve mining speeds.  These are all very capable users and this is good news !

    For the Nvidia users, we have a new miner, EWBF’s miner.  Use at your own risk.  Users report good hashrate, but lots of rejected shares and some instability.  Will be updated soon.  We recommend you stick to Nicehash’s EQM miner.
