Ideal SMBIOS for Skylake system

[kristofpetho]

Hi All,

I understand this has been discussed, but I haven't been able to find a definite answer.

I have an ASUS Z170 Pro Gaming mobo with an i5-6500 processor. As a GPU I'm using an nVidia 760 GTX card.

Two usage cases:
1. Using the 14,2 SMBIOS everything works, including second stage boot screen with a logo. Since I have a generated SSDT for the CPU everything works.
2. Using the 17,1 SMBIOS everything works, except no second stage boot screen, and I also need to use the 17,1 fix in config.plist to be able to use my 760 GTX card.

So the question is as follows:
- Do I actually gain anything by using the 17,1 signature? Or should I just use 14,2 as that seems more compatible with my GFX card?

Thank you!

Use iMac 17,1 if you want full compability for CPU states ( it is Skylake iMac after all ). Use iMac 14,2 for less hassle ( the new Mac Pro 3,1 anyone? )

Thanks. Based on this I dumped CPU states using both SMBIOS'es and indeed when using Skylake 17,1 it show almost double the CPU states. Thanks again!

Hey man,

 

What's the 17,1 fix in config.plist that you mentioned? Im using iMac 17,1 because i have Skylake cpu but Im having the issue of the black screen when I boot with my GTX 980 ti card 

 

Just in case this is my machine:

 

- Asus Z170-PRO

- Intel i7-6700K

- 32Gb G.Skill DDR4 Ram

- EVGA GeForce GTX 980 Ti 6GB CLASSIFIED

 

I've been trying a lot of things but I still cant get it to work and it's getting really frustrating

 

thanks in advance!

The fix is for exactly that
