I have a bug report for a problem on multi-card setup:
The output:
I:\Bitcoin\clocktweak>clocktweak.exe -a
===============================================================================
ClockTweak v0.9.2b - bitcoinX.com/clocktweak/
===============================================================================
Compatible GPUs found on these adapters:
Adapter#:1 ID:1 Name:"AMD Radeon HD 6670" Active:0 GPU:0
Adapter#:2 ID:2 Name:"AMD Radeon HD 6570" Active:0 GPU:1
Adapter#:3 ID:3 Name:"AMD Radeon HD 6570" Active:0 GPU:2
Adapter#:4 ID:4 Name:"NVIDIA GeForce GTX 560 Ti" Active:1 GPU:3
Adapter#:5 ID:5 Name:"NVIDIA GeForce GTX 560 Ti" Active:0 GPU:4
In reality I have "only" 3 cards - one of each type.
Further:

Interestingly, AMD's own tool (
http://www.techpowerup.com/downloads/1128/AMD_GPU_Clock_Tool_v0.9.8.html) also fails. The only program that I was able to use to overclock the AMD cards in this set-up, is Saphire Trixx (
http://www.sapphiretech.com/ssc/TriXX/)
I am really interested in a command-line tool as I am writing my own light-weight front-end (
Bitcoin Miners in Tray), that would overclock, run a selection of miners and then minimise itself to tray, capturing all stdout output.
