Hi Everyone,
I was in the same boat as a lot of people here. Once I udpated to the UEFI on my GA-Z68X-UD3H-B3 board, I wasn't able to OC even with a valid SSDT. Fortunately, I figured out what the issue was.
Previously, when overclocking in the Award BIOS, we would just enter the max turbo ratio we wanted for all four cores.
Ex:
1 Active Cores - 42
2 Active Cores - 42
3 Active Cores - 42
4 Active Cores - 42
This, combined with a SSDT and SMBIOS (preferably Macmini5,1) would give the desired overclock with speedstepping........ But this is no longer the case.
What needs to be done now is the following.
Ex:
1 Active Cores - 42
2 Active Cores - 42
3 Active Cores - 42
4 Active Cores - 41 <-------- THIS NEEDS TO BE CHANGED
-----------------------------------------------------------------------------------
[EDIT]
You can also do this:
1 Active Cores - 43 <------- THIS NEEDS TO BE CHANGED
2 Active Cores - 42
3 Active Cores - 42
4 Active Cores - 42
If you use this setting, you'll have to use the attached SSDT. The outcome will give you a "higher" overclock. I use this term lightly, because it only changes the 4 core OC by 100 MHz. This may not be worth it for some people.
Personally, I'm using 47, 46, 46, 46. I've attached the SSDT that allows this (pretty much just added the extra PSteps).
I'm also using a Macmini5,1 SMBIOS. You can use Chameleon Wizard to make this.
-----------------------------------------------------------------------------------
Also, they did away with Multi-step Load Line Calibration. This means that the voltage offset will need to be used. I have a 4.6GHz OC, so I use a +.2Vcore offset [after some tweaking I was able to get it down to a +.16Vcore offset, but your results may vary].... (everything else is auto). This can be tweaked more if you have a partition that will boot into Windows. (It is prime95 stable).
I attached my Extra folder contents as well as my Multibeast selections. Please post here with any questions.
