Some tips for miners to get started quickly:
Vertcoin Miner 0.5.2 and 0.5.3 will work fine.
Here is a sample 280x/7970 Config (340Khs) 980/1480
vertminer.exe --scrypt-vert -o stratum+tcp://caishen.leetpools.net:3333 -u user.1 -p x -v 1 -w 256 -I 13 -g 2 --lookup-gap 2 --thread-concurrency 8193
If you are having problems launching the miner or if some of the cards are showing 0Khs, or are just having problems in general make sure:
You have sufficient ram. (I am running 5 280x's on 4gb of ram). ALSO INCREASE your virtual memory. I was able to fix all the issues I had with getting all 5 cards working by setting my virtual memory to 16GB
A GREAT RESOURCE for configs regarding scrypt-n:
