I just noticed that my GPU has "Lost" its over clock and back to stock clocks with the installation of 11.12 drivers!:mad:
Before I had it unlocked and over clocked to 940 Core and 1400 Mem, using RacerX program.

I tried again with racerx and Asus smart Doctor as well but to no joy!
I did the whole uninstall drivers, clean with driver Sweeper and install 11.12 again routine before trying the RacerX and Smart Doctor but still the max clocks on CCC is 840 for Core and 1325 for Memory!

Any one know how to do this? :confused:

EDIT:
GPU - HD6950 with unlocked shaders using Asus Bios.

Does MSI AfterBurner still restrict your clocks? Might be a better option if it works.

MSI AfterBurner has a strange effect since the driver update!
My display goes off as soon as AB loads up!(Even at stock settings).
Boots up fine but with AB it is just black screen! So I had to uninstall AB.

Are you using MSI:AB Beta 10?
 
ok... jw, loads of people having a problem with beta 10... i am about to install it mind, see what it's like.

erm... i never heard of drivers, only bios updates messing around with clocks.
 
Yep I did a clean install for 11.12!
But now I cant do what I did earlier with Asus Smart Doctor or RacerX software.
MSI Afterburner works fine for now(it seems)
But CCC still shows the limits at 840 for Core and 1325 for mem.
before, when I used Smart doc/RacerX I could adjust the limits using CCC as well, with out loading Afterburner.
 
You have to mod the afterburner configuration file to move past the 840/1325 limit, after that you're golden for what clock and voltage you desire. Beta 10 working strange for me too, on occasion its only clocking one card leaving the other at ccc limit of 840/1325.

Use msconfig to stop CCC from loading and make AB load up on start up instead, so it dont get overwritten from CCC. Atleast until someone is able to unlock it; Either that or go back to old drivers that worked.
 
.cfg file is edited for the unofficial overclocking and CCC doesn't over right AB setting at the moment.
So far this is a work around, but it seem to work.
Thanks guys for all the input.

I will give RacerX another go later as I would like to do this with just CCC(with out starting AB on startup) That way, I can change the Power control feature & overclocks for some benchmarks, using just CCC.
