Epsilon however was able to boot into linux ok with his 270X, but not WB, he did get a a blank window with title bar. I'm sure he will post more info with his experience soon. Some 270s have 2GB of memory, Epsilon's 270X has 4GB, we were wondering if that was a problem with os4?

I purchased a brand new Sapphire R9 270X with 4GB memory. As sundown mentioned, it boots into Ubuntu Remix on my X1000 fine, no issues. I also put it into my Core I7 PC and confirmed it works perfectly in Windows 7 displaying up to 2560x1600 on my 30" display so it definitely works correctly.
Model details:
Sapphire R9 270X 4G GDDR5 PCI-E DVI-I / DVI-D / HDMI / DP Dual-X OC WITH BOOST
Product: 299-1E271-B00SA
SKU# 11217-04-41G
On AmigaOS4.1 Final Edition, I have the latest 2.7 Radeon HD drivers, Warp3D installed with the latest MiniGL installed from os4depot.net. Normally my X1000 has a Radeon 5450 HD and Radeon RV730 installed, with monitors for each, plus the PCIGraphics monitor needed for dual display (all in dev/monitors). Screenmode is 1920x1080 for both cards.
To have the 270X installed, I removed the 5450 monitor from DEVS/Monitors, and copied the Radeon RV730 monitor and modified it to have Monitor name "Radeon", Tooltypes changed board name of "Radeon" and COMPLENGTH of 6. DDC auto detect is not used - all resolutions are supported by the LG 24" monitor connected to it and are 60Hz.
I confirmed that with that new configuration file I could still boot the X1000 with the Radeon RV730 card installed by itself - it uses the "Radeon" monitor, even if the Radeon RV730 monitor is present too!
I then added the 270X and removed the RV730. On power on the X1000 boot logo shows, the AmigaOS4.1 Boot screen appears, and then a strange blue Workbench screen appears - link to picture here:

The intro sound plays over the top of this screen, but the background, icons, mouse and keyboard cannot be used.
Looking at the screen, it looks like the same resolution as the AmigaOS4.1 boot screen, which I guess is 800x600x256. So I put the RV730 card back in, booted up as normal and changed the screen resolution to 800x600x256 and changed the gfx card back to the 270x again.
This time the X1000 boot logo, AmigaOS4.1 boot screen appear as normal, and then it gives me a similar wb screen to the one above, but this time not blue, but looks like the colours are right. However the background, icons, mouse and keyboard still don't work:

(I also tested booting the AmigaOS4.1 FE install DVD and get the same screen as above)
I then changed back to the RV730 and removed all wbstartup items but no change when I put the 270X back in. I also tried removing non-essential stuff from the user-startup too but no change.
I tried DVI and DVI-D connectors (as I have two displays I connect both on each boot so I can see) - the display issue is the same on both connectors.
Looks suspiciously like AmigaOS4 is unable to init the resolutions on the R9 270X graphics card above the default 800x600 of the boot logo.
If I use the debug version, what am I looking for - does it output via serial port? I don't have a serial cable to capture it if it does I am sorry to say.
I can't return the 270x as it is not faulty. The vendor tests "faulty cards" and won't swap or exchange or refund unless faulty.
As you can imagine I am very frustrated with this whole situation and would like some help to fix the problem so I can use the Warp3D support with the R9 270X supported video card.
At this point I have no idea what else I can try. Any help would be greatly appreciated.
Catcha,
Epsilon
