It was a combination of solo mining (I found 2 blocks), and then using the altcoin.pw pool, which has since closed.
The settings I was using for solo mine:
cgminer -o 192.168.1.103:8108 -u miner -p blah --scrypt -I 13 --shaders=2048 -g 2 -w 256 --thread-concurrency=8192 --gpu-engine 1050 --gpu-memclock 1700 --temp-target 75 --temp-overheat 85 --temp-cutoff 95 --auto-fan -s 5 --expiry 5 --queue 0
