I'm having some trouble getting QE/CI working on my Radeon X850 XT Platinum and I was hoping that you guys could help.

Ive searched the issue a million times and tried just about everything I could editing Kexts and so on, but still, CI is software, and QE is not supported.

The device ID for the card is 0x5d4d1002.

Any help is great.

Bump....

Everything else is working fine....just need to get CI/QE working...

Shameless bump on not my own thread...with my thread:

Ahh we have the same card...

Finally someone else with the 0x54d device ID.

In Leopard graphics cards with X and 3 numbers (ie X800GT, X850XT) don't work, only in Tiger.

You can obtain change resolution with Calllisto 0.8 but not QE/CI (the Koverg Patch don't works in Leopard)

Sorry, Giorgio
