Title: GoldCoin: How to mine with a GPU using CGMiner
Post by: Stouse49 on August 05, 2013, 10:02:39 PM
This guide covers GPU mining with CGMiner (BFGMiner can also be used with this setup guide)

CGMiner Setup (Windows)
1. Download CGMiner (http://ck.kolivas.org/apps/cgminer/) (Bitcointalk thread: https://bitcointalk.org/index.php?topic=28402.0). 
2. Extract the zip folder.
3. Create a shortcut to cgminer.exe, edit the properties of the shortcut and append to the target the required parameters mentioned below.

CGMiner Command Line Options:
The standard command line options are as follows.  This will connect cgminer to a pool and start mining.
Code: [Select]
--scrypt -o [poolurl]:[port] -u [username].[workername] -p [password]
Example of Pool Mining:
Code: [Select]
--scrypt -o stratum+tcp://gld.cryptocoinmine.com:2020 -u Dayne.1 -p xExample of Solo Mining (While Goldcoin Client is running):
Code: [Select]
--scrypt -o 127.0.0.1:8122 -u <goldcoin.conf user_name> -p <goldcoin.conf password>
Useful optional parameters to set are:
-g~Number of threads to use.  Sometimes 2 is faster than 1.
--shaders~Set to the gpu's amount of shaders, google "gpu name shaders".
--thread-concurrency~Better version of --shaders, should be a multiple of the gpus shader count.
-w~Work size (try 64, 128, 182 or 256 (maximum).
-I~Intensity (12 generally works best).  High Intensities can slow down hashrates .

Example Setups
nVidia GeForce GT 630M:
Code: [Select]
--scrypt -o stratum+tcp://gld.cryptocoinmine.com:2020 -u Dayne.1 -p x --thread-concurrency 6144 -g 1 -w 128 -I 12
AMD Radeon HD 7870 (350 Kh/s):
Code: [Select]
--scrypt -o stratum+tcp://gld.cryptocoinmine.com:2020 -u Stouse49.1 -p x -I 12 -g 2 --thread-concurrency 8000 -w 256 --gpu-engine 1075 --gpu-memclock 1500 --lookup-gap 2 --expiry 1 --queue 0 --no-submit-stale -s 1
CGMiner Configuration Files
Settings can also be specified in a configuration file.  In such a case the command line arguments are:
Code: [Select]
-c <config file>Here is example config file that contains all three of the currently working pools.  If one pool goes down, cgminer will switch to another pool and keep mining.
Code: [Select]
{
"pools" : [
{
"name" : "Goldcoin VirCulPool (gld.vircurpool.com)",
"url" : "stratum+tcp://gld.vircurpool.com:3331",
"user" : "username.workername",
"pass" : "password"
},
{
"name" : "Goldcoin Cryptocoin Mine (gld.cryptocoinmine.com)",
"url" : "stratum+tcp://gld.cryptocoinmine.com:2020",
"user" : "username.workername",
"pass" : "password"
},
{
"name" : "Goldcoin Cryptopool (gld.cryptopool.info)",
"url" : "stratum+tcp://gld.cryptopool.info:3355",
"user" : "username.workername",
"pass" : "password"
}
],
"api-allow" : "W:127.0.0.1",
"api-listen" : true,
"expiry" : "1",
"failover-only" : true,
"queue" : "0",
"round-robin" : true,
"scrypt" : true,
"intensity" : "12",
"worksize" : "256",
"no-submit-stale": true,
"scan-time": "1"
}
Start Mining
Execute cgminer with all the necessary and optional parameters in a shortcut, batch file or through another software such as CGWatcher.

Many thanks go to Dayne for starting this guide.  If you post your settings and hashrates, we will add them to this post to build a database of cards, speeds and settings.

HI!
I am newbie here and would like to ask about solo mining.
1. What are the user pass options for cgminer?
2. How can i configure goldcoin.conf?

More detailed instructions on solo mining please...!

Regards!

When I try downloading the cgminer script I get the following malware blocked message

From Avast

Infection Blocked

URL:   http://ck.kolivas.org/apps/cgminer/cgminer-3.8.2-win...

Infection:   Java:Malware-gen [Trj]

Is this normal?

I did a search in the bitcointalk.org thread for "malware" and found his explanation:

It's also worth noting that even GPU mining has been used lately for botnets so cgminer once again is being flagged inappropriately as malware or a virus by various "authorities".

looks like 3.7.2 is the last official release with GPU support for cgminer anything newer is for asic only

When I started mining LiteCoin last week, the info about mining LTC says, that cgminer 3.5.0 is the latest version which supports SCRYPT. If someone knows more, please answer.

Questions about solo-mining:

I edited the Goldcoin.conf and set a new username and password. After this I created a GoldCoinSoloMining.bat in the cgminer directory and after this I switched into GoldMining Wallet and opened the tab "Mining". Here I added the server 127.0.0.1, Port 8122 and my username and password. I clicked the "Start Mining"-button in the Wallet. And I started the GoldCoinSoloMining.bat...

Is this correct? Do I need this bat-file or am I fine only using the .conf-file and the wallet settings and start it from wallet. I am confused.

Anyway, my GLD-wallet says I am mining @ 5500 Hashes...

Latest cgminer is 3.7.2 that support Scrypt.

Post by: punkrock on December 02, 2013, 06:50:41 AM
EDIT: The problem is solved. With cgminer 3.5.0 you need to start it in console with "cgminer.exe -server". With cgminer 3.7.2 it works without starting it in console.

-------------------

And could you please explain in some steps how I get started  solo mining?

My mining.bat:
Code: [Select]
cgminer.exe --scrypt -o 127.0.0.1:8122 -u conf-username -p conf-password -I 13
My goldcoin.conf:
Code: [Select]
rpcuser=username
rpcpassword=password
rpcallowip=127.0.0.1
daemon=1
server=1
gen=0
maxconnections=64
dns=1

If anyone has problems achieving good ks/s with a radeon 7870 ( I certainly had), use this setting:


cgminer.exe --scrypt -o stratum+tcp://pool:3331 -u username -p password  -I 12 -g 2 --thread-concurrency 8000 -w 256 --gpu-engine 1100 --gpu-memclock 1250 --lookup-gap 2 --expiry 1 --queue 0 --no-submit-stale -s 1

I was using very similar settings and was getting about 360 KH/s with my 7870.  My GPU settings were --gpu-engine 1075 --gpu-memclock 1500.

i'm a newbie here and i have a problem when mining by cgminer

it manifasts this:

then i have nothing to do but close cmd...
i just cannot start mining...so what's the problem?

What is your hardware setup specifically what brand video card and model numbers are you rocking and then what pool are you using?

well...it's ATI Mobility Radeon HD 5470
seems not good for mining...
as to pool, I've tried minepool and cryptcoins but they have no difference when it comes to cgminer

How can you figure out the correct values for these options?
--thread-concurrency
-w

Is it true that the higher the values, the more GPU power you use?
