Also, some tips for mild OCing in osx.
Set vcore to 1.26 and vccsa to whatever your ram needs or 1.1 set vtt to 1.1.
Connect OC key. Boot into OS X and activate OC key. Run prime95 torture test for at leaset 15 min and make sure your CPU core package doesn't exceed 78c and your CPU temp (TCase) doesn't excede 66c. If either does, Use a ps2 keyboard to control the OC key and drop your vcore till your max cpu package is less than 77 or 78 and your CPU temp (TCase) is less than67c. The CPU temp from the OC key and in the bios monitor represent tcase which is usually 10-15c lower than core temps. At 1.26 my max core package temp is 70-74c. Next use the OC key to raise the multiplier till you crash or freeze.
Reset to get back to the bios and set the multiplier to 1 less than the number you lost stability at and set your vcore to the number you lowered it to, if you needed to. save and reboot. Run torture test and unigine heaven at the same time for 20 min. If you crash or freeze or if torture test shows errors, drop your multiplier 1 more. If you don't lose stability, stop and quit unigine and prim95. Restart prime95 torture test. Now start another CPU intensive app like rendering a after effects project to f4v and verify that prime95 doesn't get any errors on any of the workers (you should have 12 which you can condense into 1 window if you like). Remember to keep an eye on core and tcase temps. At this point if you're error free and haven't crashed, you're pretty stable. If you're using BIOS controlled limited speed step, you'll want to switch vcore to offset mode and play with the - values till your vcore maxes (under full load) as close as possible to the vcore you set earlier. Note: you cannot change the offset from the OC key so you'll need to go into the bios every time you want to change it. Now you'll want to run torture test (prime95) for 12 hours and make sure you are error and crash free.
all of this can be done without the OC key but you'll have to go into the bios to make every change.
