Possible to unlock OC on Radeon graphics card?

Mellon Head said:

The card will stay at 400 MHz until it is put under load, then it will jump up to the OC frequency. Same with the memory clock.

Thx. I used Heaven Benchmark 4.0 to load the GPU while I monitored the clocks on CCC. And it does indeed jump in frequency to the OverDrive limits.

And your card is running way to hot to overclock. Just my $0.02

Yes, I see it is only a single fan card. Plus I was running it with side panel and side panel fan removed off case, at the time of measurement.

Thanks for pointing me in the right direction. I shall know better what to expect, should I go in the same direction next time.
