ATI 7650M & Mavericks - Almost Working - Need Final Help

Recommended Posts

All,

I have a Sony SVE171E13M which has a ATI 7650M 2Gb graphics card.
The Sony BIOS is locked right down, so using the HD4000 on the CPU (i7-3632QM CPU (Ivy Bridge) isn't possible, as there are zero BIOS options for GC settings.
I have Chameleon 2.2SVN r2377 installed with 10.9.2 along with Chameleon Wizard.

When I use Graphics Enabler = YES - The system picks up the card correctly 7500/7600 (Pondweed) and I get full functions, however it will only output to the HDMI Port. The laptop screen goes blank.

When I use GE=No - The system won't pick up the graphics card correctly and shows Display 7Mb, but the laptop Screen works.

I've had no luck with Clover as a Bootloader working with the GC. Chameleon is the closest to work, except for this little issue.

I'm hoping this is something simple or that the forum can provide simple terms / help in sorting this final issue out.

Any help on sorting this out would be gratefully received.

@drax101 IMO, Clover is the bootloader that can properly enable the card.

You have to dump your Video ROM from aida64 in windows, In OSX, Rename the .dmp file to 1002_6841.ROM

Then place the ROM in the ROM folder in /EFI/CLOVER/ROM.

Then open up Clover Configurator and in the Graphics section check the following options - Load Video Bios , FB name = Pondweed / Ipomoea, Video Ports = 3, Inject EDID, 

 

Dump the Video Rom from aida64 as shown in this picture (right click on bottom bar)

If you need further help, please reach back.

Devonic,
I've done as noted above plus I had to tick Inject ATi, however the system now sees the Ati Radeon HD 7650m, but only with 7Mb of memory and not the full 2Gb it has.

Any ideas please ?

The 7650m doesn't have 2GB of VRAM it has only 1GB. the other 1 GB is for the intel card. Use the ATI ROM v2 file from OSX86.net. I hear it fixes a lot of similar issues.

This graphics card has 2Gb of memory - Sony says so, Windows 8.1 says so.
I've tried the ATI ROM v2 file before which doesn't work.

 

Even Chameleon says 2Gb (see HDMI output.RTF), which is from OS X via a screen dump via the HDMI port.
