Radeon HD 7750 XFX glitchy after 10.10.3 Update

[mikeyo]

Using the old kext doesn't work. Did you try reinstalling the update and then doing the changes os the Info.plist file inside the new kext?

I just tried this and now everything is back to normal

thx

thanks you but I need to update a little bit:

After update as JayBIOS2, my Yosemite 10.10.3 with ATI HD7750 seems freeze sometime, from Console log, kernel said GPU reset.

After reinstall and change Info.plist in AMDRadeonX4000.kext, my Yosemite box (HP Pro 6300) works fine:

<key>cail_properties</key>
<dict>
<key>CAIL_DisableDrmdmaPowerGating</key>
<integer>0</integer>
<key>CAIL_DisableDynamicGfxMGPowerGating</key>
<integer>1</integer>

Has anyone with the 7750 tried upgrading to 10.10.4 yet?
Would love to hear your observations – does this hack still work?

Just F.Y.I.

My Sapphire Ultimate HD7750 start working again on Yosemite 10.10.4.

Please refer to the POST#12 above. It seems that we need to change the "CAIL_DisableDrmdmaPowerGating" from 1 to 0 on 10.10.4.

Thanks a million to JayBIOS2 and luckascesium !

You have to repair file permissions, otherwise the kext won't load again.
