Hi, As you can see in the pic I have the same bug on my hack as those with flashed PC version or those who use netkas injector. I'm trying to fix that but for that I need some help from a user that have both original and flashed GTX 285 card best way, or from different users with same mac pro specs and one original the other flashed... What I need is IOReg dumps(only device tree) and/or device-properties dump, so I can compare them and see what can be the problem. For device-properties dump in terminal: Code: ioreg -l -w0 -p IODeviceTree | grep device-properties > device_properties.txt For IOREG dump in terminal: Code: ioreg -l -w0 -p IODeviceTree > IODeviceTree.txt or you can provide only a diff from those...if someone have both cards. I know this link speed issue has been discussed and may be just cosmethic, but since I get in openmark bench worst results then HD3870 on 10.5.7(8) or snow (dunno if is the drivers fault) I still want to fix it. Thanks. Edit: As netkas said seems flashed one dosen't have this issue, so the second dump(ioreg since device-properties are injected by netkas injector) must be done with a non flashed card.
