Thanks guys! I asked gigabyte for latest bios for Z97 D3H(ignore my profile build), told them i was having memory instability issues, and they instantly sent me f10c bios. Totally fixed my system, completley stable even from deep sleep - very pleased to be back! Stu

For anyone having issues with Z97 D3H system crash when waking from sleep, and does not have the recommended memory (by gigabyte) installed then get bios F10c from gigabyte. My system is totally stable now even from deep sleep Stu

Hi Rehabman, Thanks for all your effort in the community. I have been out of the osx86 game for a while but was recently asked to build a machine for a friend. It was early days el capitan and I used z97 d3h gigabyte board with intel graphics. We agreed he wouldn't need USB 3 at present so I...

10.8 / How to enable HD4000 Just wanted to say cheers for the original posters! Just managed to get DVI and HDMI working smoothly on my z77 ds3h using the 01620005 string

Oops, forgot to mention, this was on a z68xp ud3 bios 10

i Just simply changed the multiplier to 42 for 2600k and left everything else on auto Then i used Mac Mini 5.1 smbios from multibeast and i7 ssdt from multibeast in /extra folder You also need dropssdt=Yes in boot.plist s

FYI - I was under the impression that you need only type UseKernelCache=No in once Someone else might be able to correct me but I think that the cache of kexts will be rebuilt after this and you can then go back to UseKernelCache=Yes for faster boot Stu

Article: HDMI Audio on OS X Mountain Lion Toleda rocks!

So, there is no such thing as a DVI D to VGA adpator - Do not believe anyone whio tries to sell you one! My Z77 DS3h works perfectly with DVI and HDMI using HD4000 and MAc Mini system profile I really need VGA and HDMI.... anyone with any ideas? Stu

Just use the Intel HD4000 graphics that come free with the i7 chip. This is plenty for most LR PS and FC uses. You can always drop in a good Nvidia card later when the price falls my two pence Stu

Thanks Toleda, made a well deserved donation to the site, a great resource!! Stu

might we see a Z77 ds3h uefi update too?

Thanks for the heads up on that! So currently the 2 pin header on the ds3h can not be used with co-ax or optical to a dac? I would have to edit AppleHDA v2.3.0 to get any signal from the header? or am I wrong? Stuart

Progress! Evening Toleda, Applied the edits and the DSDT compiled smoothly, cleared HDAEnabler1.kext and fixed permission - rebooted At first I could see it in system report but not in preferences So then I manually changed the Layout ID to 3 and I now have HDMI audio, you are a genius...

remove AppleHDA.kext and Enabler***.kext from S/L/E reinstall the kexts from multibeast but only the non dsdt ones How have you connected the SPDIF? did you use the 2 pin jumper on the z77 ds3h motherboard?

Yes, I run an A660 i5 almost perfectly with Lion, have not tried Mountain Lion yet, the i7 should work

My mistake Toleda - sorry... Not back until thursday, but I just assembled a new dsdt from here and confirmed the edits had been made this time, Not sure how I managed to not patch the original last time! Will get back to you with ioreg when i return home... cheers Stu

Thank you for your time... I have reinstalled HDAEnabler1.kext (is this correct?) I have used a clean DSDT and applied hdmi_audio_ami_efi_hd3000.txt patch without any edits Rebooted and saved ioreg I have attached the new edited dsdt and ioreg cheers Stu

hi Toleda, I have Z77 ds3h and HD3000 (2500k) Just wandered if you know whether the incompatibility between Z77 and HD3000 will cause any unforseen issues with this guide. I have succesfully enabled the graphics by changing the MEI device ids in AppleIntelSNBGraphicsFB.kext and...

Yes, Not inclined to buy old technology, I feel that Z77 is the way to go as well. Although Gigabytes range is not that great and there are actually NO Z77 builds in the Golden Builds forum??? The Z77 ds3h is one that I have worked with and it works well but is very basic and has no dedicated...
