What is the best overclocking tool? (windows)

[0815miner]

Ok, there are many tools out there.

Some can bring your GPU higher and memory lower than the ControlCenter
SAPPHIRE TRIXX did best for me

But other Tools work good with multi GPU rigs
like MSI Afterburner


Did anybody find a tool which can do both?

MSI Afterburner can if you edit the config file.

what do I have to do in the config?


With MSI Afterburner I have an other strange problem.
I can't get the memclock lower than GPUclock - 125MHz on my 6990 rig
Anybody solved this?

UnofficialOverclockingEULA   = I confirm that I am aware of unofficial overclocking limitations and fully understand that MSI will not provide me any support on it

It's in the bottom of the MSIAfterburner.cfg file.
Should be located in the folder where you installed MSI Afterburner

thx for the hint, the second line I found myself. 

Problem is this made my trouble worse.
After adding the EULA-Line the memclock is nailed to 1250Mhz.
Up it goes but not under the stock speed.

changing the config file doesn't always unlock your vid card for msi ab, if you can't change it I suggest using AMD GPU Tool. It will let you change the clocks but it doesn't have a fan feature, so use it to set clocks and then use MSI to set fan. This was the only method that worked for me because MSI wouldn't work. Had to scoury alot of oc forums, and this combo really works if you can do it alone with MSI AB.
