Guide says to use:
--anu-freq 270
This should be amended to:
--rmu-freq 270
You can see the freq in the top. If you use AMU, nothing changes.
--anu-freq is correct, but Rockminer's 4.3.3 build has an issue with frequency settings. You'll need to either build it for yourself or use the version of cgminer included with my installer.
