Equihash est un algorithme de hash spécifique qui a été créé par les créateurs de Zcash. Une de ses particularités est que cet algorithme demande une très grosse quantité de mémoire vive (RAM) et une grosse bande passante à cette mémoire pour que le mining soit profitable. Ainsi la production d’ASIC est à ce jour impossible et seules les cartes graphiques peuvent réellement le miner. (Il est également possible de miner equihash avec son CPU mais cela n’est vraiment pas rentable et il y a plus de perte en énergie que de gains.)
Pour overclocker votre carte, il vous faut tout d’abord un système de refroidissement efficace. En effet, la carte graphique va chauffer bien plus que dans une utilisation normale. Ensuite, téléchargez un logiciel d’overclocking avancé comme MSI Afterburner. Une fois sur afterburner, vous allez augmenter au maximum la Power Limit ainsi que Temp. Limit. Cette opération est sans aucun risque. (Nous n’allons pas toucher à l’overvoltage pour éviter que le GPU devienne instable.) Ensuite, augmentez petit à petit le Memory clock (c’est le plus important pour equihash) Normalement, vous pouvez augmenter sur plusieurs centaines de MHz (jusqu’à 400 MHz sur 1070 avant instabilité.) Si vous voyez apparaitre des barres au milieu de l’écran, votre carte devient instable. Redémarrez votre PC et refaites la manip jusqu’à la limite avant que la carte devienne instable. Ensuite augmentez un petit peu le Core clock (moins important mais il vous fera gagner quelques sol/s en plus) jusqu’à que votre carte devienne instable. Une fois les limites définies, laissez les paramètres et observez votre hashrate augmenter.
Claymore has updated his ZCash AMD GPU miner to version 12.5 adding support for the ZCash forks (altcoins using the same Equihash algorithm) as well as doing some more improvements to the miner. The latest version comes with improved fans management for latest drivers and Polaris cards, added shares-per-GPU statistics when “s” key is pressed, addend an option to use a password for remote monitoring as well as included EthMan v3.0 which supports passwords and email notifications. This is currently the preferred solution by most miners mining ZEC or other coins based on the Equihash algorithm for AMD OpenCL GPU mining rigs, the miner does not yet have support for Nvidia GPUs. Nvidia miners can go for some of the available options for CUDA mining such as the nheqminer, excavator or EWBF’s CUDA Zcash miner for mining coins using the Equihash algorithm on their hardware.
If you want to dual-boot and not just clean install you will need this step. Right click on the windows start menu, on the bottom left and select ‘Disk Management’. Select your main HDD or SSD that you want to dual boot from, right click on it and press ‘Shrink’. I suggest using at least 32gb just to be safe.
As you can see our current Hashrate is showing as 506.7 H/s, which is equivalent to the Sol/s reading on the miner. The avergae hashrate is showing as 494.6 and is the effective rate for the past 24 hours. I should point out that this rate is slightly lower than the average mainly as I shut this miner down a few times in the course of writing this guide. The final part are the valid and invalid shares. Obviously you want as near as 100% valid and 0% invalid as possible, but don’t be too concerned if your see 1 0r 2% in the invalid column on occasion.
I have put together a few videos that you may find helpful below. If your looking for a good written step-by-step tutorial I recommend this one. Building a good GPU rig will also give you the ability to mine other crypto-currencies like Ethereum.
Both brands of GPU can be good at mining Zcash depending on the model. It will take some research to find what the Cost/Performance/Electricity consumption trade-offs are. Here a list of places to start:
Pro tip: check out the following GPUs: Nvidia’s GTX 1060-6GB/1070/1080 Series; AMD’s RX 470/480, RX 570/580, R9 Series, or HD 7990/7950 (if used cards are available, try to get them from a gamer instead of a miner, with a warranty if possible). As with everything, do your own due diligence to evaluate GPUs based on their hashrates, power requirements, availability, and price.
Replace “eu” for your location, “ZEC-ADDRESS” for your zcash wallet address (transparent address), replace “-t 8” for the number of threads you want to use, and lastly replace “-og 0” for the number of GPUs you’re using (as in -og 0 1 2 if you’re using 3 GPUs)
The card should have at least 1 GB of RAM, or it won’t be able to properly mine Zcash. This is a correction from the video, as EWBF supports GPUs with just 1 GB of RAM, compared to Ethereum’s 3 GB requirement. However, many older cards may not be energy efficient enough to turn a profit, so check on whattomine.com by entering your card’s info.

August update on my mining farm, proudly joined the 30,000 club with over 30k sols / hash on equihash which I am currently mining Zcash or ZEC with. I am using the 1080 TI, 1080 TI, 1080/1070/1060 Mini Trio GPU DIY Rig build.
You need to take in to consideration the system which requires another 100w. 1080 with 80 percent power and 2 1060 also at 80 percent power should be fine. If it doesn’t work try to reduce power further to 75 percent. I have my 1080s set to 70 percent power.
Theres a few more things we need to do before we can start running the miner. First of all, we need to add this string of code to the config.txt, especially on 1-2GB video cards. This will ensure everything runs smoothly. Add this code to your config.txt file:
After letting your newly setup miner run for about 20-30 minutes, you can check the pool to confirm you shares are being counted and see some pool-side statistic of your mining progress. On the top right of the Flypool Zcash homepage (shown above) you can enter your Zcash wallet address and click on Check Status to get to your own wallet personal statistics page.
It’s worth noting that the AMD solutions tend to have a better ROI than than what you’ll get with Nvidia GPUs. However, if you find good oppers on Nvidia GPUs, don’t hesitate to choose those over the AMD alternatives.
It is advisable to put the fan regularly on a certain percentage so that the heat of the card is about 60 degrees (note that during the day the house is warmer and the temperature will rise accordingly).
Zcash makes use of the Equihash algorithm – a Proof of Work algorithm that is unique to Zcash for now. It was invented by Alex Biryukov and Dmitry Khovratovich, and makes use of Wagner’s algorithm to provide the PoW that’s required for consensus in the Zcash Blockchain.
We’ll be starting the miner using a simple text file that tells the operating system to launch the mining It also allows the configuration of settings when EWBF starts. These files can be created an edited with any text editor. On the Windows platform, the correct file extension is .bat. On Linux, it is .cmd.
Difficulty this is the measure of how hard it is to generate a new block in the blockchain. The difficulty is designed to adjust every 2,016 blocks (roughly 2 weeks) to balance out the rate at which blocks are created. The difficulty has an absolute minimum of 1, but not such limit exists for the maximum.
Below is an example of a batch file that we use on one of our Windows-based mining rigs. Everything is contained in a single line in the .bat file. That single line specifies the program to be run (miner) and a few settings that customize the miner’s activity. Finally, and most importantly, one of Zcash wallet addresses is specified so mined Zcash goes to the right place. Here’s the .bat file that we are currently using to start mining. Scroll to see all of it’s contents if necessary.
This is a list of the most popular Zcash Mining software for each platform, some of this software contains a built-in developers fee. I try to keep this list up to date as I can, if there is a broken link or missing software please drop me an email.

HVAC is a serious additional expense when used to cool a mining or folding rig, it will add rough ballpark 40% to your electrical cost (somewhat less if you have a VERY high efficiency unit in the 15+ CEER/SEER range as opposed to common units that are typically 9.3 or so)

hi， bminer also faster than other miner around 10-15%, but reject data it’s so high, i using on nicehash to mine, reject data around 3% to 5%, i will try direct to mining zecoin later and report of bminer.
I use the MSI GTX 1080 TI AERO. These cards are the best in performance and cooling. They have from to back airflow that keep these cards cooler than most. Note: Do not buy the Gigabyte version of these. They have firmware issues and crash.
There are a lot of user-submitted crypto mining benchmarks out there. Our methodology is simple. We ran these systems 24×7 for 72 hours and averaged the last 12 hours. That is an important feature because NVIDIA Pascal GPUs will throttle under heat so the first 20 minutes of mining can be much faster than full heat-soak. We have a nvidia-docker mining container to simplify mining so we can deploy it on our cluster machines and provide consistency.
Hi Marilyn, Imgur.com is a good site for image uploads, just as a tip. The Mega page won’t load for me for some reason, probably due to my browser config. Google Drive works though. The one you want to download is Zec miner 0.3.4b – or whatever the latest working version mentioned on the forum page happens to be. I’m not really understanding the problem. Sounds like you downloaded the miner OK, just it’s named differently? That won’t be an issue. I suggest you run some virus scans on the miner you downloaded and then proceed with the rest of… Read more »
Now with all that said, it also does not mean that a mining program cannot contain a virus, or that it isn’t a virus itself, so don’t just blindly trust it either. It is just that there is a valid reason for a high rate of false positives when it comes to such software. Just as a general rule, I would not load any mining software on a machine that contains a cryptocurrency wallet, or one that you do any type of financial work on. It is best to play it safe and keep your mining rigs separate from your important information, so a separate machine is best that is dedicated to mining if possible.
Now that you’ve got your hands dirty, just sit back and watch your zcash roll in! Be aware that you are mining to a transparent address (it starts with t). You can follow this guide to learn how to create a private and transparent wallet
