Sry for late reply, but yeah.
Overdrive comes w/profiles pre-installed for a 955.
If you look in the AMD/Overdrive {default} dir you will find "955BE_RB-C2.xml"
Make a copy of this as a backup, rename copy or original and open the XML up and edit for your needs...I renamed mine "965BE_RB-C3.xml" and Overdrive picked it up...
There were a number of games for the 955, sometimes I just tryto make an educated guess on what I need.
My Rule of Thumb is:
check CPU Core affinity 1-3, leave core 0 unchecked
check Boost State
Set core Voltage to 1.5v {careful w/ this one! - make sure you are not over volting}
Set P-State to P0
Core Multipliers I leave at default as I have increased Mult. via Bios. {+4}
When I open Overdrive I usually do a quick sanity check on various temps, etc. - and bump voltage to 1.5v...
Overall, has been pretty Stable, though not 99.99%...some games stress things too much lol, BF3, etc.
For Fan control I enable just Fan xPert in AI Suite II...and for GPU I use ATI Tray Tools {luv that lil program}
In addition, I sometimes run "Process Lasso or Game Booster" for that added oomph...
Getting about 100 fps in WoW w/ max settings, view distances, etc. Not a really taxing game, but it is a little finicky w/ the core affinities.
One last thing: make sure your NB voltage is able to supply what your RAM wants....Can tweak this in OD too, if BIOs is default...
