I'm using sgminer with nfactor support.
http://www.sgminerwindows.com/sgminer-nfactor.php
Sapphire Tri-X R9-290 (not X). There is another card in my system (HD6450) just to render my desktop, disabled in sgminer by using -d.
Config (use your own settings for pools):
---
{
"pools" : [
{
"url" :,
"user" :,
"pass" :
}
],
"nfactor" : "11",
"expiry" : "10",
"log" : "5",
"queue" : "0",
"scan-time" : "1",
"api-listen" : true,
"api-allow" : "W:127.0.0.1",
"kernel-path" : "/usr/local/bin"
}
---
sgminer launch (the first figures in TC, gpu-engine, and so on, are for the disabled HD6450):
---
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_ALLOC_PERCENT 100

The Nfactor for rotocoin is:
minNfactor = 10
maxNfactor = 30
Which value is better to put taking your config as basis? 11, 10, 30?
