GUIMiner-scrypt: A GUIMiner for mining scrypt coins
« on: August 12, 2014, 09:52:19 PM »
The program is a frontend for reaper and cgminer and is intended to simplify things for new miners and remove yet another barrier to entry for scrypt/litecoin mining.

Supports scrypt mining (Litecoin, Dogecoin, etc) and scrypt-n mining (Vertcoin, etc)

Download link:

 :) :)

To upgrade from old versions, delete the entire contents of your old folder (settings are saved elsewhere) and replace them with the new zip file contents.

Source on Github:

Please ensure you have the following dependencies installed
• Latest AMD drivers:
Known working for all cards AMD driver (12.8):
12.8 32-bit
12.8 64-bit

Q: How do I use the stratum proxy?
A: Enter the host and the stratum port and click start.  It should announce that the proxy is connected.  Then, point your miners at host: localhost, port: 8332.  Run your miners as normal; you should see shares/hash rates reported.
Also note that cgminer has its own stratum support built in.  To use that instead, select "Yes" for Use stratum in the miner tab and point the miner directly at the stratum port of your pool.  If you still want to use the stratum proxy with cgminer, you must select "No" for this option.

Q: How do I update cgminer to the latest version?
A: Download cgminer and dump the contents into the /cgminer/ folder, replacing the old version of cgminer.

Q: Why are my speeds not close to those reported in the original FAQ?
A: In addition to tuning the parameters of the program, you will need to tune the GPU core speed and memory.  For 5xxx/6xxx cards a good ratio is 0.70 - 0.80 core / memory clock speeds.  For 7xxx cards, ratios are best under 0.68, with the 7970 preferring ratios at or under even 0.57 in reaper.
To find your memory speed from the core speed, simply divide by the ratio, e.g. 900 MHz core / 0.68 = 1325 MHz RAM.

Q: Shares reported by the stratum proxy are not the same as shares reported by the card.  Why is this?
A: It is a bug to be fixed in a later update.

Q: I hit the start button with cgminer for the first time and nothing happened!
A: Wait for 2-3 minutes and see if mining begins.  The reason is that cgminer needs to build the kernel to run.  If nothing still happens, post in this thread as it may be a bug.

Q: I'm getting lots of stales with cgminer and high thread concurrencies; why is this?
A: The current cgminer kernel seems to have trouble with high thread concurrencies.  If it throws lots of reject shares that come up at the pool as invalid, try switching to reaper.

Q: I'm using an nVidia card and it doesn't work, why is this?
A: You need to install the CUDA toolkit for the kernel to compile.

Q: My miner windows doesn't appear onscreen!
A: Delete C:\Users\You\AppData\Roaming\poclbm\poclbm-scrypt.ini.

Q: Why does my cudaminer miner tab hang on "Connecting"?
A: Because python's subprocess can not see cudaminer's output no matter what I tweak on it.  If the author of cudaminer releases a new version in the future that has stdout streams compatible with python 2.7, I will fix this.  In the meantime, if you navigate to the "/cudaminer/" directory, you'll see that a batch file is added after you press start that you can check your performance from.

Q: Something is wrong and cgminer isn't giving me helpful output to GUIminer-scrypt.  What do I do?
A: For more verbose output, run the batch file ("your-miner-name.bat") in the /cgminer/ directory.  This is generated whenever you hit the "Start" button and will show the cgminer console so you can better troubleshoot your problem.

Q: How do I setup a backup pool?
A: Add a second pool with "-o stratum+tcp:// -u user -p pass" in extra flags.  You can add as many as you like in this fashion.
