rayap Posted August 16, 2013 Share Posted August 16, 2013 Replaced my HD4850 with a HD7770. The old card worked perfectly in ML and Mavericks, except for the occasional ID modding. With the new card, the first problem of booting from a GUID disk was overcome with a boot0af file. The second problem was when HWMonitor was launched, system crashes and was overcome by yanking out GPUsensors. The third happened when waking up from sleep, an empty desktop bereft of icons appears and system freezes. This can be resolved by replacing the AMD kexts from ML but the white screen problem reappears as in ML. Anyone out there having similar Wake from Sleep display freeze and system crash with HD7XXX cards in general or HD7770 in particular and is resolved.

k3nny Posted August 16, 2013 Share Posted August 16, 2013 Hi, GPUSensors has a known bug causing the system to freeze when used with HD 7000 series. You should remove this plugin and rebuild caches. Link to comment Share on other sites More sharing options...
rayap Posted August 18, 2013 Author Share Posted August 18, 2013 Resolved. Guess the default Framebuffer caused it. Added back PEGP dsdt code (removed for old card) and set Chutoro. Thanks to an article by rampagedev. Link to comment Share on other sites More sharing options...
rayap Posted August 31, 2013 Author Share Posted August 31, 2013 With GPUSensors of HWSensors 5.2.779, GPU Die temp is OK and no crashes (though history graphs do not seem to draw). Link to comment Share on other sites More sharing options...
