crisorlandobr 1 Posted January 13 Posted January 13 Hi I gave up Big Sur because of compatibility with some programs (Specially Parallels with a lot of bugs and no updated working version with USB fix) and decided to go back to Catalina Installed everything fine, and Opencore Sanity Checker is ok (The only issue here is SSDT-PLUG that does not work with Ivy Bridge (but I tried to check if overclock would work ok) with some warnings but everything is stable I created all SSDT in Windows including the SSDT-PLUG just to make sure it would make my overclock work I am sending a link with my EFI folder and screenshots from geekbench5, Valley benchmark and Intel power gadget that only shows 3.6GHZ Max when the CPU should be working at 4.4GHZ There are some big differences from Windows and Mac regarding CPU and GPU performance and the GPU is very slow comparing to Windows (Using MS drivers and no AMD applications) This model had some issues with green screen and it happened in Windows and Mac, but I downgraded firmware since the update one had a factory oveclock that was making it too hot and causing it to shutdown and after downgrade it is working fine, but still very slow in Mac and with no temp showing My machine I7-3770K, ASUS Sabertooth Z77, 4x8GB GSKILL TridentX 2666Mhz (Working at 2600MHZ) System drive is a Corsair MP510 2TB NVME using PCI-E (BIOS is patched to boot PCIE NVME) CPU Overclock set to 4.4Ghz and had to OC RAM settings to use 2600MHZ even with the RAM being faster (Platform limit) I send the folder to sendspace since it would not fit here Ps: Cinebench R15 goes to 777 in Windows and 579-615 in Mac if attached file does not work here its here too https://www.sendspace.com/file/syi2j0 Tks Olarilai7-help.zip Quote Share this post Link to post Share on other sites

Big Sur new version only fixed network with some plist configuration changes but USB was not working at all But Catalina is working well and stable The only issue is GPU speed and lack of temperature monitoring and CPU overclock not working even with all SSDTs dumped Tks Quote Share this post Link to post Share on other sites
