    In fact.
    R9 nano is Tonga, like r9 380-380x-390

    No, it's not. It's a Fiji chip - in fact, it's simply an R9 Fury X that's been binned exceptionally well.

    Hey guys, question: I've got the deamon and wallet up and running. Benchmark blake256 with cgminer works just fine (1.5 GH/s on a single Radeon HD5850) but I can't get mining started on my pc. I am running Windows 10 64bit with 64bit CGminer 3.7.2 and when I try to connect cgminer to 127.0.0.1 it does not start mining. I've checked credentials, they are correct. (if i use non-existing user or pass it tells me) In the background I can see dcrwallet and dcrd connecting and processing blocks in the CMD windows that are opened up.

    error message when starting "cgminer --blake256 -o 127.0.0.1:19109 -u MYUSER -p MYPASS"

    JSON invalid data
    No suitable long-poll found for http://127.0.0.1:19109
    Most likely you have the wrong URL, forgotten to add a port, or have nog set up workers
    Pool 0 URL http://127.0.0.1:19109 user: MYUSER Password MYPASS
    Press any key to exit, or cgminer will try again in 15 s.

    this keeps repeating itself

    Do I need a specific cgminer with a specific blake256.cl ? I presume that if anything is wrong it would tell me what but I cant find out why this happens.. I'm missing something, I only used cgminer in the past for pool-mining.

    I'm no expert, but I believe you need to specify the port number when you run cgminer. "cgminer --blake256 -o 127.0.0.1:19109 -u user -p pass"

    This would be my guess, as well.

    Is there a way to check wat port it is using? I did not specify a port myself so it should be default.

    Since IMO, the official CGMiner hasn't yet been completed to the point where all the little nitpicks have been taken care of, likely it's using a default port that has nothing to do with Decred. Specify your IP and port like so - -o http://127.0.0.1:19109

    In that example, the IP is 127.0.0.1 (localhost), and the port 19109.

    Make sure you are synced and wallet connected without errors. What is your dcrwallet command line looks like? Plus use cgminer from Decred.

    My hero, seems to work just fine using this version of cgminer. Only downside is that this cgminer for Windows is a 32bit version. I'm now running at 950 MH/s compared to 1.5 to 1.6 GH/s on the cgminer 64bit version.. (benchmark)

    are there any settings for cgminer to make it run faster? In the past I tried setting worksize, intensity etc while mining other coins. This sometimes resulted in better performance while some settings did the opposite. Any advise? I us a stock Radeon 5850

    How to Setup and Optimize your CGMiner Config File


    Anyone who starts out mining Decred if you want to get the best Mhash/s from your GPU or GPU’s. This being said its not that difficult to get it running and optimizing it for your graphics card. I will explain the entire process of creating the config file to changing settings so that you get the most MHash out of your card possible.

    Setting up cgminer for the first time: (skip this if you already have cgminer running)

    1. Download the newest version of cgminer from its Git Repository (https://github.com/decred/cgminer/releases)
    2. Unzip cgminer to your hard drive (somewhere you will remember)
    3. Navigate to the cgminer folder and open cgminer.exe
    4. When it asks for your pool address enter it there with port (i.e. http://127.0.0.1:19109 -)
    5. Next it will ask for your Worker so enter that (i.e. username.1)
    6. Next enter your workers password when it asks and press enter
    7. If all information was entered correctly it should now start mining.
    Create a Config File for cgminer: (skip this if you already have a cgminer config file)

    1. After cgminer begins mining press “S” for settings
    2. You will have a list of options show up, next press “W” for Write Config File
    3. It will ask about naming the config, just press enter for the default name (cgminer.conf)
    4. You now have a config file for cgminer
    NOTE: if you are happy with the MHash you are getting at this point all you need to do is run cgminer.exe to begin mining the pool you setup earlier since its all saved in the config file you just created.

    Optimizing you cgminer config file:
    Decred mining uses your GPU core and not the memory so you will want to clock your memories core down and over clock your GPU core. Keep an eye on your GPU’s temperature when doing this as you want to make sure it doesn’t get too hot and damage the GPU. Most newer cards can run around 80-85 degrees celsius safely for prolonged periods of time but I would not recommend letting it get hotter than this.

    1. Lookup your Graphics cards default core and memory clock speeds first thing
    2. Navigate to and open your cgminer.conf file in notepad
    3. Change the intensity to 5
    4. Change the gpu-engine to your default GPU core clock
    5. Change the gpu-memclock to about 1/3 of the default clock
    6. Leave everything else the way it is and save the config file.
    7. Re-open cgminer via cgminer.exe and after around 5 minutes record your MHash
    Start Overclocking your GPU in cgminer to squeeze out MHash:

    1. Close cgminer if you have it open to edit the config file again
    2. Go back to your cgminer.conf file and open it again in notepad
    3. Increase your gpu-engine by around 50 and save the file
    4. Open cgminer.exe and again watch the MHash and Core Temperature
    5. Continue these steps until you have increased your MHash as much as you can while keeping a temperature under 80-85.
    Note: If you crash, see artifacts and/or go over the recommended temps then back off the clock 25 and re-test until you get to a stable working condition.

    There are other options that you can mess with in cgminer although everything mentioned above is the best way to get MHash to its optimal setting and keeping your card safe from burning out. Please also take note that I am explaining the process but am not responsible for using this information or misusing this information and damaging hardware. Good luck DECRED Mining and please consider a donation if this was helpful to you.
