GIGABYTE GA-Z77X-UD5H DSDT Help

Hello,

 

I am looking for somebody who can optimize / patch my DSDT. I would like to do it myself, but I'm scared I screw up my computer by doing something that shouldn't be done. I already extracted my DSDT with MacIASL and included it as attachment.

 

At the moment I'm using Tony's (yes, indeed that one) way to set up a DSDT Free installation as that's possible with the board I have, but I think I can get it all just a little bit better by having a patched one.

 

While you're at it, could you also explain to me the differences between a DSDT free and with DSDT? I want to use Clover (still researching) as I'd like to boot UEFI into Windows. I have Clover already running on my laptop, so that's not an issue for me. I only don't want to screw things up, that's all.

 

If there is a volunteer who wants to take a look at it, that will be very appreciated.

 

Thank you very much in advance.

 

I also have an ATi Radeon HD6950. In Windows I use VirtuMVP (IGFX is enabled in BIOS and I'm working on that one in OS X, so the discrete don't need to be removed).

 

My system specs:

 

Mobo: GIGABYTE GA-Z77X-UD5H rev. 1.0

CPU: Intel Core i7-3770

RAM: Crucial 16GB DDR3 1333Mhz

Graphics used in OS X: Builtin HD4000

Discrete Graphics (not used in OS X): ATi Radeon HD6950

A DSDT file is only necessary if you need the table patched to activate or fix a feature (eg: graphics card injection for full QE/CI or Sleep/Wake support). However, it's not always necessary and some computer can run 100% Ok without patched DSDT. The patched table simply overwrites the original table read from BIOS but if the latter is sufficiently well written, patching is not necessary and OS X will simply make use of the table found in the BIOS.

If you want to try this, rename the file to "DSDT.aml" (without quotes). The file have ALC898 injection, you must delete HDAEnabler from S/L/E or E/E

 

Thank you very much for the patched DSDT! I cannot try at this moment, but sure will in the coming weeks :)

 

Thanks again!

Well, then I learned something too :) Thanks for the explanation. I thought that any system only runs fine with a DSDT, but that isn't true. Thank you.

I'm sorry to not respond for so long, but I want to replace my HD6950 (the thing just doesn't work) with a GTX 7x0 (maybe TI) series card. I heard that these will work natively. I guess that I need to extract my DSDT again, because of the change in GFX card?

 

I really wanted to try it, but it's just too much hassle with this HD 6000 Series card.
