for those who don't know yet, you can mine SHA, Scrypt and X11 coins at
Altnuts.com and get paid out in Opal. Help us build the official SuperNET Multipool by mining with us at
www.altnuts.com...Here, no registration needed, quickly: copypaste altnuts address, add your opal address and the name of your miner and let it crush with the SuperNET Multipool !
For those who are new with mining, here is a complete guide:
Windows OS and AMD Graphic card
You need to:
have decent drivers: at least 14.6 ->
http://support.amd.com/en-us/download/download & install Microsoft.NET 4.5 framework->
http://www.microsoft.com/fr-fr/download/details.aspx?id=42642download & install AMD APP SDK (for Windows 32 bits) ->
http://developer.amd.com/tools-and-sdks/opencl-zone/amd-accelerated-parallel-processing-app-sdk/ go to the second board AMD APP SDK v2.9.1 and choose the correct one (for Windows 32 or for Windows 64 bits).
download and extract sph-sgminer x11mod ->
https://github.com/lasybear/sph-sgminer_x11mod (i like the 4.1.0)
Then you need to create the .conf file
(Remember the extension must be seen, to be sure):
Windows 8 : Open a File Explorer window and click the "View" tab and tick "File name extensions".
Windows 7/vista : Open Windows Explorer and click the "Organize" button towards the top left. Choose "Folder and search options" from the menu. Then click the "View" tab in the window that opens, then scroll down and untick "Hide file extensions for known file types".
So create a new text document with your notepad and copy/paste the following: (remember to edit oYOUR_OPAL_ADDRE55 and yourminername):
{
"pools" : [
{
"url" : "stratum+tcp://stratum1.altnuts.com:4333",
"user" : "oYOUR_OPAL_ADDRE55.yourminername",
"pass" : "x"
}
]
,
"intensity" : "16",
"worksize" : "256",
"kernel" : "x11mod",
"lookup-gap" : "2",
"thread-concurrency" : "8192",
"shaders" : "0",
"gpu-threads" : "2",
"gpu-engine" : "1050",
"gpu-fan" : "0-0",
"gpu-memclock" : "1500",
"gpu-memdiff" : "0",
"gpu-powertune" : "0",
"gpu-vddc" : "0.000",
"temp-cutoff" : "87",
"temp-overheat" : "83",
"temp-target" : "75"
}... Save this file as sgminer.conf in your sph-sgminer x11mod folder (beware not to save it as sgminer.conf.txt).
These settings work for AMD 7970, R9 270x, R9 280x.
You should change thread-concurrency, gpu-engine, intensity (usually 13-18) and gpu-memclock values to fit your GPU habits. (if you change thread-concurrency, delete the x11modXXXXXXg2tcXXXXwXXXl4.bin file in your sph-sgminer x11mod folder).
In order to change your gpu-engine and gpu-memclock value please read
https://litecoin.info/Mining_hardware_comparison, the "C" Column is for gpu-engine value and the "M" is for gpu-memclock values.
(remember that if you want to change settings when the sgminer.conf is saved you must right-click and choose edit, instead of open)
Now create another text document with your notepad and copy/paste:
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
sgminer.exe -k x11mod -o stratum+tcp://stratum1.altnuts.com:4333 -u oYOUR_OPAL_ADDRE55.yourminername -p x
... Save this file as for example Buyopal.bat in your sph-sgminer x11mod folder (beware not to save it as Buyopal.bat.txt) and create a shortcut that you cut/paste on your desktop: to start mining, just double click this Buyopal.bat shortcut ! be patient, first time it take 30 seconds to run.
