Hello!

I have just bought two PowerColor HD7950 PCS+ for building new rig.
Problem is that I cannot downclock their memory lower than 625MHz.
625MHz is the best result using MSI AB 2.2.1 with UnofficialOverclockingMode=2.
I've tryed to restart MSI AB, but memory clock borders stay the same - from 625 to 2250MHz.
On 7870 and 5850 borders changed after restart...
I've tryed to manually modify profiles, but no clocks lower than 625MHz apply...

I'm using win 7 x64, Catalyst 12.4...

Any ideas?

UPD: Problem solved, I've just deleted folder /profiles in MSI AB folder, after next start it was possible to set clocks lower than 625MHz.
