RivaTuner and 4870 clocks

[Messerschmitt]

Hi there,

I am posting here as it seems no one in the guru3d forums is able to point me in the right direction, IF any exists, not even unwinder.

Anyway, the problem I have with RT and my HIS 4870 512mb is that RT detects my 2D clocks (200 core and 500 memory), and allows you to modify between 100-300 clock and 250-750 memory in the low-level hardware overclocking. My 3D clocks are 750 core and 900 memory.

A lot other people that do have 4870's, does not have this problem, as their RT detects the correct 3D clocks, and they can OC around the correct clocks.

I have tried a full removal of CCC and Catalyst drivers, and RT, and re-installed the drivers, and RT without installing CCC, yet RT will still only detect the 2D clocks.

Does anyone had this problem and managed to make RT detect the correct 3D clocks of 750 core and 900 memory?

What version of RivaTuner are you using?

Have you tried any other tools?
