Its free for now on amazon kindle, soon to be on paperback. Check it out ! It goes over the how, why and if a crypto currency mining operation is profitable or not, and how to value it. It helps the reader decide between different types of hardware and how to to compare them. Let me know what you think and happy mining to all.
Here are a few miner updates from the past few weeks that can improve your mining uptime and performance. For Nvidia users, you should always check out NemosMiner and the various ccminer updates here. For AMD users, we have new updates from Claymore. We have an update to the ETH Dual miner, now v.10.3. These updates mostly fix issues with the latest Adrenaline AMD drivers. The Cryptonote update is now at v.11.2. And Zawawa has updated his Gateless Gate Sharp to v1.1.16, which is now becoming a very interested free software.
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.
Nicehash has updated their Excavator software, now to V1.2.11 Alpha. Included in the update is support for Titan Xp, new algo support (Lyra2rev2) and AMD bug fixes and improvements. Check it out here !
Welcome to the build from hell. There has been a lot of despair and confusion with the parts contained in this build and I will show you how to make it work. Lets talk expectations : This is a low-cost solution that is semi-portable, fits into a 15A dedicated socket and will be dual-mining Pascal and Ethereum. Let’s get to work !
The rig itself is a cheap rack from Walmart, all metal and easy to setup. It costs 26$ (all prices will be in CAD). I have inserted a piece of wood/shelving that somehow (the crypto gods have smiled upon thee) fit just perfect. Whatever you do, do not put any exposed components (motherboard…) directly on metal. I have also purchased a 3000+joules 6 foot cord surge protector from Newegg, for about 20$. The rest of the parts are straightforward. 8gb RAM DDR4 2133mhz, Pentium G4440 CPU socket 1151, 120GB Hynix SSD, 5 RX570 MSI Armor 4g and 1x RX570 ASUS STRIX 4g, EVGA 1000GQ PSU and of course the infamous MSI Z170A SLI motherboard. All these parts were chosen because they were on sale and at a good price, and two, because they work well for rigs (except the motherboard mind you). The reason I have chosen this cursed motherboard is because of non-availability of 6 GPU motherboards. This particular model was also on sale, plus a Mail in rebate and was too cheap to ignore. I can suggest doing a 5 GPU rig, it may be much easier to do.
Now we assemble. First is the CPU, which is easily placed into the socket (do not assemble on the anti-static bag, because it is only anti-static INSIDE), then the stock CPU cooler, which is also very easily installed. Next install the RAM by pushing firmly down on it. I have sourced case screws and used them to prop up the motherboard so it leaves a gap under it to permit airflow, although that is optional. At this point set up your PSU and install all cables. Connect the motherboard main cable, and the CPU 8 pin cable. Then insert your first GPU in the x16 slot. Connect your SSD to the SATA port. You are now ready to plug in your screen, mouse and keyboard.
Start it up ! Press del to enter the bios. You must enable WIN8/10 mode in the options, and set the PCI to GEN 1 (or gen 2). Set 4G decoding to disabled. Save and reboot, and install WIN 10. Once that is done enter the bios again and disable the WIN8/10 mode. We won’t be needing that anymore. Set Power ON after reboot/power outage. Install your remote monitoring software, Claymore dual miner, GPU-Z, MSI Afterburner, SRBPolaris V2.6, ATIWinFlash, DDU, ATIPixelPatcher, and download AMD drivers. In this particular case, you need to download an older version – such as 16.9.1 or 16.11.x, and a newer version, such as 17.4.4. Use DDU to reboot into safe mode. Select shutdown option.
Install all your GPU’s and connect them with the USB risers. No more than 2 on a single cable. Don’t use the Molex adapter if you can. Start it up again. Open device manager, you should see all 6 GPU’s, with little yellow triangles. All is well so far. Now, thanks to atanas012 on bitcointalk (if i’m getting the source wrong someone please correct me), this is THE ONLY WAY I HAVE FOUND TO MAKE IT WORK on this mobo. Read it here. Open the older driver install file, and extract it. Once its extracted, close the installation window. DO NOT INSTALL IT. Then, do the same for the newer driver. DO NOT INSTALL IT. As atanas012 puts it: “Copy and replace all content from “C:\AMD\Non-WHQL-Win10-64Bit-Radeon-Software-Crimson-16.9.2-Sep21\Packages\Drivers\Display\WT6A_INF\B307117” to “C:\AMD\WHQL-Win7-64Bit-Radeon-Software-Crimson-ReLive-17.4.3-Apr17\Packages\Drivers\Display\W76A_INF\B313057” (Basically you copy the old driver over the new)“. Go in your device manager again and right-click on the first GPU with a yellow triangle. Select update drivers, and manually select the newer driver folder (in this case, the 17.4.4). It will install and tell you that all is well. Don’t forget to accept when it tells you its a weird driver.
Reboot and enter BIOS. You must now enable 4G decoding. Save and reboot.
Now all should work. Run MSI afterburner and GPU-Z to check your ASIC quality for an indication of how low you can put your voltages. The thing with this Frankenstein driver approach is that you may not be able to modify your voltages anymore (EDIT: You can still modify your GPU BIOS to have the voltage you want, 0.88v is a good place to start). But you can use Afterburner to reduce your clock speed, and that will change the phase and lower the voltage according to the voltage table. Put memory clock to 1900 or above to start. Set up a custom fan profile, and select overclock on startup. Save profiles. You should get voltage at full load around 0.87 to 0.97mv. Your claymore .bat file should look like this:
“set GPU_FORCE_64BIT_PTR 0 //optional for 570/580
set GPU_MAX_HEAP_SIZE 100
set GPU_USE_SYNC_OBJECTS 1
set GPU_SINGLE_ALLOC_PERCENT 100
set GPU_MAX_ALLOC_PERCENT 100
EthDcrMiner64.exe -epool pool:port -ewal user.rig -epsw x -esm optional -allpools optional -dcoin second coin -dbg 0 (for logs) -mode 0 or1 (dual mining) -mport -3333 -dpool pool.port -dwal user.rig -dpsw x -dcri depends on GPU -di 012345″
Run the file and check your voltages, and power usage. Once that is done, close it. Run ATIPixelPatcher now. Open ATIWinFlash. Select your GPUs, and save a copy of the BIOS for each different GPU. Now in the ATIWinFlash, you can only see 3 GPU’s at a time. I suggest you use the command line, its better. Its Atiflash -p GPUnum filename.rom to flash. Check your GPU’s with atiflash -i. But first, open up SRBPolaris, and open your saved .rom files. Go into memory timings, and copy 1500 to above. If you feel like it, you can try other options, 1625 to above, or even input your own memory timings and test things out. I will keep it simple. Save to A DIFFERENT FILE NAME. Next, use atiflash to flash the bios to all your cards. Reboot.
Run Claymore again. You can now play with the memory clock, 2000mhz is a good starting point for most cards depending on memory type and memory timings. Everything should work fine. If your rig crashes, open the log file and see which GPU froze. Increase the core clock and reduce the memory clock of that GPU, and try again. Check your power usage with a Watt-meter. I can get anywhere from 930 watts dual mining Pascal, 170mhs and 1500mhs depending on voltages. Good luck and happy mining ! I hope this guide helped you, and please consider donating to the people who made this possible on bitcointalk and elsewhere, to the people who made the tools you use to make it all work, and if you feel inclined, to me 🙂

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.
