A Treatise on CUDAMiner

Thanks CBuchner for creating Cudaminer!

If this helped please upvote for other puppy miners!

I've added popular cards and configs to the bottom.

Disclaimer: I'm like every other shibe.. I can make mistakes, if something doesn't look right, please, please correct me! Thanks!

Some edits: A Minor Observation. -c 1 performs better than -c 2 generally.

Update: Place:

setx GPU_MAX_ALLOC_PERCENT 100

on a line before the cudaminer.exe line, you may get a little more performance out of the miner.

Hi! So you're looking to Mine using your Nvidia Card, don't know how to setup CUDA Miner?

The basic format for CUDA Miner's .bat file will be.

Stratum (For HTTP: Replace stratum+tcp with http):

Ex: cudaminer -H 0 -i 1 -l auto -C 2 -o stratum+tcp://xyz.yourpool.com:porthere -u username.worker -p password

What each flag does:

[-H] scrypt also has a small SHA256 component to it: 0 hashes this single threaded on the CPU. 1 to enable multithreaded hashing on the CPU. 2 offloads everything to the GPU (default)

[-i] list of flags (0 or 1) to enable interactive desktop performance on individual cards. Use this to remove lag at the cost of some hashing performance. Do not use large launch configs for devices that shall run in interactive mode - it's best to use autotune!

This setting set at 0 will cause your GPU to run at 100% and most likely will cause lag while even tabbing through your browser! Set at 1 if you're trying to use your PC while mining.

[-l] specify the kernel launch configuration per device. This replaces autotune or heuristic selection. You can pass the strings "auto" or just a kernel prefix like L or F or K or T to autotune for a specific card generation or a kernel prefix plus a lauch configuration like F28x8 if you know what kernel runs best (from a previous autotune).

[-C] list of flags (0 or 1 or 2) to enable use of the texture cache for reading from the scrypt scratchpad. 1 uses a 1D cache, whereas 2 uses a 2D texture layout. Cached operation has proven to be slightly faster than noncached operation on most GPUs.

In Depth & Getting the most out of your card:

Well, let me start off with a checklist.

Do you have the latest version of CUDA Miner?

If Yes then Move on.. If no (Or you're not sure), then go here: https://bitcointalk.org/index.php?topic=167229.0

Do you have the latest drivers installed for your video card? You must have R331 or newer for latest CUDA Miner

If yes.. carry on! If not.. http://www.nvidia.com/Download/index.aspx

Well then, now that that's done...

A few things you'll need to know before going on..

What video card do you have?

If you know.. Carry on. If you're not sure.. Then Install GPU-Z to find out!

http://www.techpowerup.com/downloads/SysInfo/GPU-Z/

Now that you know what video card you have, you'll have to find out what compute version it is using. Find your video card on this chart. (For ease, use ctrl + F on windows and then type in the # of your card)

Now.. Moving on and now that you know what version you have..

We now can find out what Kernel CUDA Miner is best suited to using!

Available kernel prefixes are:

L - Legacy cards (compute 1.x)

F - Fermi cards (Compute 2.x)

S - Kepler cards (currently compiled for Compute 1.2) - formerly best for Kepler

K - Kepler cards (Compute 3.0) - based on Dave Andersen's work. Now best for Kepler.

T - Titan, GTX 780 and GK208 based cards (Compute 3.5)

X - Experimental kernel. Currently requires Compute 3.5

(Copied from the CUDAMiner Readme)

For Legacy Cards you're best off using auto.

Now find the # of SM(X) units for your card here: http://en.wikipedia.org/wiki/Comparison_of_Nvidia_graphics_processing_units

Fermi is limited to 16 Warps per SM Unit Kepler is limited to 32 Warps per SMX Unit.

If you're on Fermi, with The 560 Ti which has 8 SM units your .bat file will look something like: cudaminer -H 0 -i 1 -l F8x16 -C 2 -o stratum+tcp://xyz.yourpool.com:porthere -u username.worker -p password

If you're using Kepler, with the 660 (Seems to be a popular card), which has 5 SMX Units your .bat will look like: cudaminer -H 0 -i 1 -l K5x32 -C 2 -o stratum+tcp://xyz.yourpool.com:porthere -u username.worker -p password

Titan should be the same as Kepler. (Although someone else may know more on this topic..)

Ta-Da!

To get the most out of your card, you can tweak the -H and -C with 0 1 or 2. I would not recommend using -i 0 if you are trying to browse the web while using your computer, things can stutter, a lot, and annoy you.

WOW! Much hash. http://s15.postimg.org/onsy6sdjf/doge2.jpg

General Mining Tips:

1. Be sure to find a good pool of course! Try to find a PPLNS Pool with 0-1% fee. I'm not going to suggest any, I don't want to seem biased. There are many good pools! (Thanks Crazypotatoes on doges.org for suggesting this)

2. Use GPU-Z to monitor temperatures on your card. If it gets too hot you may want to shut it down. Mining doges isn't worth it at the expense of your computer and or video card. (Crazypotatoes again)

3. Use MSI Afterburner to increase your fan speeds. (Don't Overclock if you're not sure about what you're doing. There are many guides on this but I don't think its worth it if you're not sure what you're touching.) (Yep Crazypotatoes)

Some cards and configs:

560 Ti: -H 0 -i 1 -l F8x16 -C 1 -m 1

660: -H 0 -i 1 -l K5x32 -C 1 -m 1

670:-H 0 -i 1 -l K7x32 -C 1 -m 1

780: -H 1 -i 1 -l T9x20 -C 2 or -H 1 -i 1 -l T12x32 -c 1

Hello dear friends.

We are just 3 days old pool (such young shibez), seeking for your kind help. We need more miners. Already found some blocks in just 3 days of opening and such big blocks! Help this startup pool to grow!

Why would you join our pool?

• Hashing power should be distributed on as many pools as possible to avoid 51% attack on Dogecoin network

• More pools means more stability against DDOS attacks (they can't DDOS all pools at once)

• Friendly and helpful people on IRC channel (there to help and support)

• We have very positive feedback from current users

(Crossposting idea to try to get a mod response) I sent the mods the following message about merging the two subreddits. Feel free to comment your thoughts on the matter.

I made a post on /r/dogemining which seemed to show community agreement in combining the two subreddits (http://www.reddit.com/r/dogemining/comments/1ts9zt/can_we_combine_dogemining_and_dogecoinmining/). I know there is a history between the mods of both subreddits but I would encourage you to put aside your differences in view of the larger goal -- getting shibes to the moon, together. Anyhow, I look forward to a response from y'all (on the thread would be nice).

Hi guys,

As most of you probably know there are 2 dogecoin mining subreddits. There was a thread several days ago where merging them together was discussed for the best of the community. The moderators of both subreddits have agreed this is the way forward for the betterment of the dogecoin mining community.

This subreddit will therefore be closed and redirect to /r/dogemining where me and /u/matthew_boyd will be made moderators.

Hope to see you guys over there :)

When you are mining, your computer is solving 'hashes' and once it solves one, it reports it back to your pool. This is the number "your valid" and has virtually NOTHING to do with the ACTUAL number of coins you will receive when your pool solves a block.

This, as others have mentioned, is simply the number of "solved" hashes that you have contributed to the pool.

Once a block is solved, your pool reports this to the dogecoin network. This is when you get an 'unconfirmed' account balance of some coin. This balance is calculated by taking the block reward that the entire pool earned, and working out what percentage of the total hashes YOU PERSONALLY contributed.

Then this is all verified, and basically there is a chance that another pool solved the block at almost the same time, but reported it to the network SLIGHTLY before your pool.

This means that the block you had 'unconfirmed' coin for gets 'orphaned'. When this happens you get nothing. Generally, the bigger the pool, the less the chance of solving an 'orphaned' block.

If your pool got it first, then the amount of coins is 'confirmed' and you can withdraw them.

edit Also, the hash rate you see on a web-based pool dashboard is an AVERAGE calculated over about 10 minutes. If you have been mining for less than 10 minutes, this will NOT be the actual hashrate you are achieving. If you want to know exactly how many hashes you are getting, look at the output from the miner you are using.

I think I may put together a beginners guide with screenshots today. Let me know if this would be helpful.

Hope this helps, feel free to delete this if it's unnecessary (but I've seen quite a few posts indicating otherwise ;) ). Also feel free to correct anything I got wrong (I was trying to make it as simple as possible).

Hellow friends. We much appreciate your help with mining and contribution to Doge family. We're especially proud of our IRC users. Such fellows, much helpful and kind!

We want to grow more and since this has been great experience so far, we'll be giving rewards to ten random miners when we reach next goals:

• 400 miners (10 x 5.000 doges)

• 700 miners (10 x 15.000 doges)

• 1000 miners (10 x 30.000 doges)

PS: We are working on a new feature which will help fellow shibaz with no mining rigs and no funds to get some Doges. More to follow in a few days. We want so spread Doges to as many people as possible, long live Doge, to the moon!

Hey doges!

So basically this sub-reddit is for:

• Posting your mining setups.

• Posting questions about mining.

• Generally helping each other.

• Be friendly!

Also, make sure to have a look at the sidebar, it has all the information you need to get started posting here!

Many thanks, so grateful,

The Dogecoinmining team! ;-)

I feel the community really needs a resource like this. Because if I had a Doge for every-time taught a newbie how to Mine on Ubuntu, I would be a very rich doge!

EDIT: Sorry if it looks funny, Reddit doesn't like the numbers I put in for some reason.

If you have Ubuntu you have likely not upgraded because you think you cant mine on 13.10, and while that has been true in the past, a few people have got it figured out. So feel free to upgrade. If you are not on Ubuntu, Seriously you should consider using it. Even if its just on an older desktop.

Alright, so lets get a few things clear, I am assuming that you just FRESHLY installed Ubuntu 13.10 x64 on your system. I am assuming that you have no drivers, and no miners. You will need at least a key board and a mouse. The guide will be done in several parts, this first part is for most AMD Graphics cards. If you have an Nvidia, or just want to mine with your CPU, please check back later for those guides!

When reading this guide, please remember that as I give you commands to type into the terminal, Anything between { and} must be included. Do not copy and paste the {}.

Lets get started, If you have not already done so, Install Ubuntu 13.10 64Bit From Here (http://www.ubuntu.com/index_asus.html)

*1. Lets start by making sure you are up to date. Open up the terminal and enter this:

{sudo apt-get update && sudo apt-get upgrade}

Let that run for a bit.

*2. Once that has finished we are going to download some applications we will need:

{sudo apt-get install dh-make dh-modaliases execstack libxrandr2 libice6 libsm6 libfontconfig1 libxi6 libxcursor1     libgl1-mesa-glx libxinerama1 libqtgui4}

*3. Once that has run its course we are going to install the ssh server. Remember this command is going to make your computer shut down. While it is shut down, carefully install your graphics cards. If you don't have any experience with this, I suggest you 3 minutes to watch this guide, because failure to install a graphics card the right way can destroy it.

(http://www.youtube.com/watch?v=O9x097QRXeA)

{sudo apt-get install openssh-server sudo shutdown now}

*4.Install your Card(s) and turn the computer back on.

*5. Make a new folder called "AMD DRIVERS123" inside of your download folder. Downoad the following 3 things into that folder. (1. AMD Drivers: http://support.amd.com/en-us/download/incomplete) (2. AMD APP SDK: http://developer.amd.com/tools-and-sdks/heterogeneous-computing/amd-accelerated-parallel-processing-app-sdk/downloads/) (3. AMD ADL SDK:http://developer.amd.com/tools-and-sdks/graphics-development/display-library-adl-sdk/)

*6. Ok, now we need to unzip and compile those drivers. So, open a terminal my right clicking inside of "AMD DRIVERS123". The enter this:

{unzip amd-catalyst*.zip
chmod +x amd-catalyst*.run}
{sudo ./amd-catalyst*.run --buildpkg Ubuntu/saucy}

*7. Now we need to install the drivers. Enter the code exactly as you see it, don't worry, the first command will fail, we are expecting it too.

{sudo dpkg -i fglrx*.deb}
{sudo apt-get -f install}
{sudo dpkg -i fglrx*.deb}
{sudo reboot}

Your computer should now reboot.

(If this failed, you probibly need to remove the old drivers. Do this

{cd /etc/default
sudo pico grub}

Change the line:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset"

Now save by pressing [CTRL+x]

{sudo update-grub} this will make the change perminent.
{sudo reboot -n} Reboot with new settings. Once it starts back up try installing the new drivers again.)

*8.GREAT! You are really on a roll! Now we need to update AtiConfig

{sudo aticonfig --initial --adapter=all}

*9.Time to install the APP ADK:

{tar xvf AMD-APP-SDK*.tgz}
{sudo ./Install-AMD-APP.sh}
{sudo reboot}

*10. WOOT! You are so close to diggin that sweet Doge!! Its time to download CGMiner. IMPORTANT NOTE! You need to get CGminer 3.7, IT IS THE ONLY ONE THAT WILL WORK. Do not get any older or newer, Just this. :

{sudo apt-get install git unzip
git clone -b 3.7 https://github.com/ckolivas/cgminer}

*11. Ok, now go back to "AMD DRIVERS123", Unzip AMD SDL SDK 6.0. Once you have it unzipped, go the file called "include", open it up, copy everything inside, then go find CGminer. Copy these files into the CGminer file called ADL_SDK.

*12. To install CGminer, we are going to need a few things. Get all of these.

{sudo apt-get install build-essential autoconf libtool libcurl4-openssl-dev libncurses5-dev pkg-config libudev-dev}

*13. Lets go ahead and compile CGminer.

{cd cgminer}
{./autogen.sh}

*14. Ok, when you did that, it told you GPU was not supported, time to fix it.

{./configure --enable-opencl --enable-scrypt}

(if you did it right you should now get this: OpenCL...............: FOUND. GPU mining support enabled scrypt...............: Enabled ADL..................: SDK found, GPU monitoring support enabled)

*15. If everything has been good so far then

{make}

*16. MATHEMATICAL! Now lets get it set up to run a test.

{nano test.sh}
{!/bin/bash
export DISPLAY=:0
export GPU_MAX_ALLOC_PERCENT=100
export GPU_USE_SYNC_OBJECTS=1}
{./cgminer -n}

*17. Now save by hitting [Control+x][y][Enter]

*18.Lastly lets CHmod test.sh

{chmod+x test.sh}

*19. TIME TO RUN THE TEXT!!!

{./test.sh}

(If your output looks like this your ready to go!!! CL Platform 0 vendor: Advanced Micro Devices, Inc. CL Platform 0 name: AMD Accelerated Parallel Processing CL Platform 0 version: OpenCL 1.2 AMD-APP (1214.3) Platform 0 devices: 1 0 Tahiti GPU 0 AMD Radeon HD 7900 Series hardware monitoring enabled 1 GPU devices max detected)

*20. Excellent! Now we have it installed, its time to pick 2-3 pools, and get accounts set up at each of them. I currently use These 2, and If I find another I like I'll update. If you have a really awesome pool you would like me to include on the list, feel free to message me.

Pools: http://doge.cryptovalley.com/ (great community, server not super stable, but they have a chat. I hang out here a lot under the handle 'StrongBad' feel free to stop buy and ask questions)

https://dogehouse.org/ (Super stable pool, Great contests, super friendly, and they pay your miner a bonus if you find the block!)

Choose your pools, go to their sites and sign up. VERY IMPORTANT!!! Use different usernames and passwords for every mining site. If one site gets hacked, you don't want to give them a way to steal everything!!!!! Don't worry about the worker names and passwords being unique or complex tho, the most they can do with this is mine for you.

*21. Ok, now go to the CGminer folder, and open up a Terminal Window.

{sudo ./cgminer}

This should start ./cgminer up with some really basic settings, and not pointed at any pool. Lets fix that: First press [p] to go to pool settings Now [A] and enter the information for the 1st pool. For instance if you are signing on for dogehouse: (Input server details: stratum+tcp://stratum.dogehouse.org:3333 Username: 'yourusername.workername password: 'yourpassword') If you got no errors, you did it right! Your miner should now connect and start to mine very slowly.

Now, do the same thing for all your other pools. the reason we do this is because Doge Coin pools are constantly being DDoS attacked, and this way your worker automatically switches over to a good pool if one go's down.

*22. time to save your current settings press [Enter] to get back out to the main menu, then [s] to bring up settings. Now press [W] to write a Config file. Name it DogeCoin.conf, and make sure to save it in the location it directs you too.

*23.OK! So, now we have everything set up to its basics. What you need to do now is sit down, and fine tune your Card(s). Its really early in the morning, and I need to get some sleep, I will add more on how to tune your card tomorrow in another post, and link it HERE:

Or, I will help you find the best configuration for your card(s). However as this is quite a bit of work, I do charge a small fee. Contact me with your card(s) information and I will get back to you right away. I generally let you decide how much to pay me.

This is my first ever guide on reddit! If you enjoyed it, or if it helped you please remember to upvote! I am going to start doing an educational YouTube series about Bitcoin, and will likely be doing a side program about Doge, if I find time and funding!! You can find that here: All tips are appreciated! DPTwcQreASwzt6TeWBWFb6Kz9ZU5Sezvr9 If you have any Questions, feel free to ask, I will get back to you ASAP.

Happy Digging everybody!

I just opened a coinbase wallet. They allow you to send and receive dogecoins to your username instead of using a long address. My username is @dogecoins

But how do I mine and get free coins to add to the wallet? I’m new to this.

There are many guides all over the 'net for building a mining rig.
The "holy grail" of any mining rig is to have:

1. the highest hash-rate-to-purchase-costratio and

2. the highest Kh/s-to-watt ratio.

Starting with the first metric: If you build this 6 GPU mining rig with the suggested R9 270, you will have a hash-rate-to-cost ratio of 1.5 hashes-per-dollar (2,700Kh/s divided by $1,800). However, if you build the same rig with five of the R9 280x (suggested alternative GPU in the guide), you will have a lower (worse) ratio of 1.42 (3,700 divided by $2,600). So even though you get a higher hash rate from the R9-280x vs the R9-270, the R9-270 is the better deal. Based on this first metric, here is a cost analysis for a build with each of these cards using a base hardware cost of $370 for motherboard/cpu/ram/hdd/etc and only modifying the cards and the psu(s):

• 6x AMD R9-270 | $200/ea | 1.3kw psu | total: $1.8k | ratio: 1.5

• 6x AMD R9 270x | $250/ea | 1.3kw psu | total: $2.1k | ratio: 1.3

• AMD R9 280 (why isn't this card released? should be a rebranded 7950 according to tech powerup

• 5x AMD R9 280x | $400/ea | 1.6kw psu | total: $2.6k | ratio: 1.42

• 4x AMD R9 290 | $600/ea | 1.6kw psu | total: $3.1k | ratio: 1.06

• 4x AMD R9 290x | $670/ea |1.6kw psu | total: $3.1k | ratio: 0.82

• 5x AMD 7970 | $475/ea |1.6kw psu | total: $3.1k | ratio: 1.2

• 3x AMD 7990 | $1k/ea |1.6kw psu | total: $3.1k | ratio: 1.1

Moving on to the second metric: Here's a list of commonly used mining GPU's with their associated Kh/s-to-watt ratio, assuming average results with under-volting. Higher is better:

• AMD R9 270 - Kh/watt: 3 - 150w/ea - $200/ea

• AMD R9 270x - Kh/watt: 2.5 - 185w/ea - $250/ea

• AMD R9 280 (unreleased... re-branded 7950 according to tech powerup

• AMD R9 280x - Kh/watt: 2.7 - 250w/ea - $400/ea

• AMD R9 290 - Kh/watt: 2.75 - 300w/ea - $600/ea

• AMD R9 290x - Kh/watt: 2.7 - 300w/ea - $670/ea

• AMD 7970 - Kh/watt: 2.65 - 270w/ea - $475/ea

• AMD 7990 - Kh/watt: 2.85 - 470w/ea - $1,000/ea

Based on both metrics, the R9 270 wins first place.

What do you think of these calculations?

We've updated the "under $1k" Budget Mining Rig Guide to reflect the current market availability of GPU's, motherboards and other relevant build components.
Feel free to check it out, use it, critique it and make any suggestions to improve it!

Just a few days ago I was pulling ~1k an hour. Now I'm getting a lot less coins, in smaller groupings. Sometimes I'd get 300 at once, atm the average seems to be around 80.

Is this the pool (Dogehouse), me (480kH/s), or dogecoin?

very noob question: do i need to keep the dogecoin wallet application open all the time if i have auto payments set up with pools? if not, would it be correct to assume that any pending auto payments will appear the next time i sync the app? much thank very appreciate

If you are interested, I created a Windows application that uses the cgminer API to run your GPU's through different combinations of engine/memory clock speeds to find where you're getting the best hash rates. It helps to fine tune your configurations and squeeze out a few more Kh/s. I'm calling it CGBenchmark.

I've used it to optimize my Sapphire R9 280x's and MSI 7950's. I found each individual GPU achieves the optimal hash rates at a slightly different engine/memory combination. I have tested it with cgminer 3.7.2.

You can either run it locally on your mining system, or remotely from a different computer. I find running it remotely works better. It is explained in more detail in the readme file, and the interface is pretty self-explanatory. It started as a simple script, and has evolved into its current form.

Below is a link to download it. It is just an executable and a readme file.

Anyways, I just thought I'd share and give back to the community a little. Hope you find it useful.

I've been mining off-and-on at the doge.cryptovalley.com pool. Let me start by saying that I've always received a prompt payout upon request; and, in general, have had no problems with them at all. However, last time I went to log in I had forgotten my password (that's what I get for making all my passwords unique). So, instead of looking at my accounts spreadsheet, which had the password, I guessed a few times. That was the wrong thing to do. After a few guesses I was told that my account was locked and to contact the site's support. Upon clicking "Support" in the sidebar I was greeted with the following message:

This product comes 'as-is' without any warranty. Please check the Apache License, Version 2.0, for details.

So, I then just issued a password-change through the form provided. I was sent an email with a link to click in order to complete the password change. The change was successful, but I am still told that the account it locked and to contact support. I tried (long shot, I know) responding to the password-reset email and have not heard anything back. I don't know exactly how much of my Doge is caught-up in limbo (probably 500-1500). As a last attempt to get in touch with the site admin, or at the very least warn others about this situation, I am posting here.

Again, I'm not accusing anyone of malice; if anything it's probably just an oversight.
