Radeon HD6970 (Cayman XT)

[xeno74]

I have bought a Radeon HD6970 (Cayman XT). I successfully tested it with ubuntu MATE 16.04.6 LTS PowerPC and with Fedora 27 PPC64 today and the hardware 3D acceleration works great on both distributions. The Cayman cards are the fastest and last released Radeon cards with support for hardware 3D acceleration on Linux PPC Big Endian. New cards are working but without hardware 3D acceleration.

Hi All,

I have bought another Radeon HD6970 (Cayman XT). This time for the X1000. I successfully tested it with ubuntu MATE 16.04.6 LTS PowerPC and with Fienix today and the hardware 3D acceleration works great on both distributions. The Cayman cards are the fastest and last released Radeon cards with support for hardware 3D acceleration on Linux PPC Big Endian. New cards are working but without hardware 3D acceleration.





Cheers,
Christian

I have one of these cards and tried it in my X5000 running Fienix. I boot into the uboot menu, go to Command Line and enter the commands to boot Fienix and as soon as I hit Enter the screen goes black and there is no signal to the monitor. Trying to boot AmigaOS does the same thing. MorphOS will boot, but the display is very flakey. I am currently using a Radeon 6670 which works okay for all three but I would like to use the 6970.

Any ideas?

[Fogg_80]

This card is very hungry of power, do you have a suitable PSU?

[akmar1]

It's a 550w PS which meets the requirements of the graphics card. It's possible that's the problem but I don' think it would be that big of a power load just booting. There is no signal to the monitor as soon as I hit Enter.

[xeno74]

The latest git kernels don't boot with Radeon NI graphics cards. I created a patch for solving this issue.

@Xeno79
Did this card have HDMI output and if so did it work? Or only DVi?

Also dd you buy them second-hand from different people or from some shop?
