estofan Posted February 24, 2010 Share Posted February 24, 2010 maybe somebody is fighting with the same problem i had... i tried 2 different boards until now: GA-EX58-UD4P and GA-EX58-UD5 and 2 different graphik cards: CLUB ATI radeon HD 4870 1GB and Saphire Radeon 4870 1GB with both graphik cards i had many sleep problems... tried many different kext extensions but nothing works for me... at least i removed the batery from the board and started again with the genius KAKEWALK installer, used the Build 10C2234 OSX installer from the new 27" imac, changed only the AHCI mode in the BIOS ......and surprise...surprise.... everything works out of the box !!! (with QE/CI open GL...) goes down to sleep and wake up again !! i think you have always problem with new hardware... but for me the best decision is EX-UD5 and the Radeon 4870 Link to comment Share on other sites More sharing options...
