My hackintosh I5 2500k Asrock Z68 Extreme 3 Gen 3 8Gb Kingston 1600 OCZ Vertex 2 WD 500Gb green Gigabyte GTX 560 (not TI) Corsair CX 600 Antec Three Hundred I have installed Mountain Lion, Multibeast post intallation and upgraded to 10.8.1, everything looks all right, the system is stable. An overclocking would help me very much (i'm working with FCPX), but the problem is that I don’t have DSDT for Z68 Extreme 3 Gen 3 and because of that the OS is not reading the values from bios. Have to say that I add <key>SMexternalclock</key> <string>100</string> <key>SMmaximalclock</key> <string>4200</string> in SMBIOS.plist and OS read the frecvency just fine, but without a sign of better performance (9500 pct geekbench, 4.99 CINEBENCH 11.5 CPU). I've even tried SSDT i5/i7 for OC, but no results. If someone knows how and want to build an DSDT for this MB and would like to help me, I would be grateful. Thx!
