In Topic: AMD r9 270 problem

20 May 2015 - 04:27 AM

Hi I have a XFX Double D R9 270 with 1x DP, 1x HDMI and 2x DVI-Dual Link. I have (3) Monoprice WQHD monitors, two of which is connected directly to the graphics card through DVI-Dual Link. The third is connected via an active DP to DVI-Dual Link adapter. I was using a HD 5850 before the upgrade so I know that this configuration works.

 

Here's what I have done so far:

1. I modified the kexts with the correct device ID: 0x6811.

2. In Clover I have InjectATI enabled.

3. I also set the FrameBuffer to Hamachi, replaced the framebuffer with the following:

 

00 04 00 00 04 03 00 00 00 01 00 00 22 05 01 02 DP

04 00 00 00 14 02 00 00 00 01 00 00 11 02 05 05 DVI-DL

04 00 00 00 14 02 00 00 00 01 00 00 10 00 03 06 DVI-DL

00 08 00 00 00 02 00 00 00 01 00 00 12 04 02 03 HDMI

 

The values are based on Vlada's tutorial and the attached ROM file downloaded from https://www.techpowe...048-131119.html

 

So far, only the monitor connected to the DP works. For the ones connected to the Dual-Link DVI ports, one does not receive a signal at all and went into sleep, the other one displays a black screen. However, all three monitors show up in System Information.

 

Wonder if anyone has the same graphics card and is able to help?

 

Thanks.

Did someone here get Sigmatel 9247D (D975XBX2, badaxe2) working?
