Well, I got this Hightech Excalibur R9600 (nonpro) and any utility I
use for OC, it has no effect on this card.

Actually, the freqs I set manually are holding only for 10 or less
seconds. WTF?

I tried Powerstrip, Rage3D Tweak, Radclocker... No use.

Is there any other way to overclock this card?

I know that Sapphire Atlantis 9600 i OC-able enough but can someone
send me BIOS image from this card? Maybe that would help, what do You
think?
