Hello, guys. I have 2 x 7950 GPUs ready to go. But after searching for like 30mins i can't start minning. Using cgminer 3.7.2 and this pool -
http://utc14.yacoin.club/index.php?page=gettingstarted only gives me low share difficulty errors. Every share is rejected. Seems something wrong with algorithm beind used. Help me star mine this cool coin. Thank you
This may help - I only CPU mine. But for GPU's CGMiner needs a patch for Scypt Jane Chacha (Note UTC is NF14 now)
https://bitcointalk.org/index.php?topic=727023.new#newCGminer 3.7.2 patch which adds support for "scrypt-jane" (or scrypt-chacha if you prefer). This is used to mine coins such as QQC (and Ultracoin).
* NEW Kalroth Builds *
I've released builds of the Kalroth CGminer with integrated Scrypt-Jane support. This means you can use things such as "xIntensity" and "rIntensity" (raw intensity) settings to get the most out of your miner. Please note that these builds are brand new and I've done very little testing with them. If there are any problems, please let me know.
The patch is an attempt to implement the scrypt-jane algorithm while preserving the functionality of the standard scrypt algorithm. In english, this means you should be able to mine either scrypt or scrypt-jane with your patched cgminer, instead of having two separate mining programs.
The patch is based on ybcminer 3.3.1-yac2, which was in turn based on cgminer 3.3.1.
Tested and working with a QCC pool and a standard scrypt mining pool. You can not mine standard scrypt coins and scrypt-jane coins at the same time. You need to restart cgminer with the correct command-line arguments.
This patch adds the following command-line arguments to cgminer:
--scrypt-jane Use the scrypt-jane algorithm for mining
--sj-nfmin <arg> Set min N factor for mining scrypt-jane (default: 4)
--sj-nfmax <arg> Set max N factor for mining scrypt-jane (default: 30)
--sj-time <arg> Set StartTime for mining scrypt-jane (default: 1376184687)
Alternatively, as of patch version 0.03, you can set the same options as above in your cgminer.conf file, e.g.:
Example Scryot-Jane Config for CACHeCoin:
"kernel" : "scrypt-jane",
"sj-nfmin" : "4",
"sj-nfmax" : "30",
"sj-time" : "1388949883",
Example:
cgminer --scrypt-jane --sj-time 1387769316 -o stratum+tcp://stratum.cipherpool.com:8842 -u <username>.<workername> -p <password>
... and you'll love this: you'll most likely need to re-tune your graphics card(s) to work optimally with scrypt-jane.
The developers of ybcminer and cgminer did all the hard work. I just did a bunch of copy/paste and some re-factoring.
Here's a table of settings for various YAC clones for use with this patch. The settings were taken from Here. If you know of more please let me know by contacting me through my Blog.

Build Instructions (Linux): CGminer 3.7.2 Patch Build Guide
Revision History:
v0.01:
Never Released. I had various versions of v0.01 around so decided not to release any of them. That said, v0.01 and v0.02 were made within hours of each other, so don't feel like you missed out :-)
v0.02:
Initial public release.
No known bugs, seems stable.
v0.03:
Added support for cgminer configuration file options.
