ZCash Claymore Miner v.12.1


    A new update for Claymore ZCash miner is out, now at v12.1

Latest version v12.1:

– slightly improved speed for some cards, about 410H/s on stock 390X, 450H/s on stock Nano, 290H/s on stock 280X, 300H/s on stock RX480.
– slightly improved stability. If it is still unstable for you, reduce “-i” value.
– fixed issue with wrong hashrate when “-li” or “-ttli” options enabled.

    You should see a small increase in hashrate and it seems it solves some stability issues people were having.  There probably won’t be any significant updates to the Equihash miners – although you should watch zawawa’s Gateless Gate miner that we talked about before.  He may soon get the same speeds as claymore, but it is a free to use miner.

ZCash Claymore Miner v.12 and other updates


 Good news everyone, we finally have a Claymore Zec miner update.  We may have more in the future too.  This update, V.12, has a solid speed increase for almost all GPU’s.

Claymore's ZCash AMD GPU Miner.
=========================

Latest version v12.0:

- improved speed, about 405H/s on stock 390X, 450H/s on stock Nano, 290H/s on stock 280X, 295H/s on stock RX480.


NOTES:
1. Reduce intensity ("-i" option) if miner is unstable.
2. It seems there is no way to get full speed on latest drivers for Fiji cards, at least in Windows. So don't use latest drivers for Fury, use 15.12 or 16.3.2

    You can find the bitcointalk thread here.  So far a 280x gets 310 sol/s, a 390 gets 400 sol/s, and 470/480 get up to 270-300 depending on your settings.  If you take into account the fees, we are still pretty close to optiminer in terms of hashrate.

    You may also want to mine PascalCoin, which you may have heard of.  I haven’t talked about the coin here yet because of some problems with the mining software and wallets, but its a good alternative.  Read up on it here.

    Another really interesting project is Gateless Gate.  Updated by bitcointalk user Zawawa, he is using SGminer-GM.  So far his updates have made it almost as fast as Claymore or Optiminer for ZCash, and you can mine ETH, XMR and PascalCoin on it.  In fact, since its SGminer, you can mine pretty much anything on it.  This is an open-source project and I highly recommend you read up on it.  If you like it, please send a donation to Zawawa, it will encourage him to continue and he can also buy his wife nice things so he can spend more time coding 🙂  Find the thread here !

   Finally, if you are looking to expand your GPU rig operations we have some good suggestions.  We posted a while back a R9 Fury deal for 364$ on amazon.ca which is still valid here.  For USA people, there is a MSI Armor Rx470 4g for sale on newegg.com.  Its on sale for 150$ after MIR and you get the hitman game, which you can sell.   If you are looking to buy equipment and want advice or a second opinion on prices / gear, then leave a comment and I’ll be happy to help you out.

GPU deal of the week !


     For you Canadian miners out there, here is a great deal.  The Sapphire Nitro Fury is on sale again for about 360$ and free shipping.  And you can expect between 400 and 450 sol/s mining ZCash.  So ROI about 6-7 months depending on your electricity costs.  Its a solid GPU all around for mining and gaming.  Even in 4k.  Click on the link below to go see the Sapphire Amazon page (referral link).

Optiminer/Zcash v1.6.0 (GPU, Linux, AMD) Update


    Optiminer has released a new update, v1.6.0.  We are still waiting for Claymore’s update, but so far this is clearly the best ZCash miner out there.  Some users report up to 300 sol/s under linux for Rx480 cards.  We can report under windows up to 400 sol/s for an R9 390, and up to 230 sol/s for an R9 380.  As for the Tahiti 280x, we now get speeds of 300 sol/s (+-10% for all cards, depending on your overclock).  A lot of bugs related to the –experimental-kernel tag have been fixed.  We’ll update once Claymore updates his miner, but remember Optiminer’s fee is included in the hash rate you see.  We speculate the recent gains were in part due to the reduced fee, now believed to be 2.5%.  Go see the Optiminer Bitcointalk thread here !

All you need to know about USB Risers


    USB Risers can confuse people sometimes.  So here is a quick review of what you can buy and how they will help you with your GPU mining.  You shouldn’t buy anything below v.5, although that doesn’t mean they won’t work – It just means you aren’t getting the latest products.  For Molex connections, you should buy Ver.5c.  Then we have Ver.6c, which enables you to connect a 6 pin connector.  And finally, the Ver7.s enables you to connect a SATA wire directly into the riser, without the use of the sketchy molex/SATA adapter.   Remember never to overload your cables – You won’t have this problem with the 6 pin usually, but for SATA its better to have just one or two max on a single cable, and same for Molex.  In case of doubt, use less, and always check cables for heat while running.  If they are hot to the touch, then your setup needs to change.  Below are some sponsored links to each version that you can buy on Amazon.


Optiminer ZCash v1.4.0


    Optiminer ZCash v1.4.0 has just been released here !  Best results are on linux, maybe 10-15% higher for Polaris cards.  Fastest ZEC miner out there, and the fee is already included in the speed, so what you see is what you get.  No fancy controls like claymore, and no flashy colors – but – faster speeds.  For example (on windows) We can get 375 sol/s on R9 390 1100/1500 and 205 sol/s R9 380.  Only downside is you cannot connect to coinotron so far.  Don’t forget to set –experimental kernel command, run the .bat file with –help to see all the options.

Claymore’s ZCash GPU miner v11.1


    Another quick update by Claymore for ZEC.  V11.1 improves speeds by a bit and most importantly improves compatibility.

Latest version v11.1:

– improved speed, about 365H/s on stock 390X, 385H/s on stock Nano, 260H/s on stock 280X, 260H/s on stock RX480.
– improved compatibility.
– some bug fixes and minor improvements.

    On Linux, you should try Optiminer 1.3.0 and compare speeds.  What is important in this update is that for Polaris and Fiji cards, it may be important to switch to linux for future speed increases.  And if you have a Fury/Nano, you should have 15.12 AMD drivers or 16.3.2.  I Still get 390sols with a Fury on V.10.0, so if you don’t have linux installed, stick to that.  In any case for Polaris cards, its more profitable to mine ETH.
