More than 64 threads Xeon E5-26xx v4 build

[JKGiova]

Hi everyone, that's my first post in this community. I haven't Hackintoshed at all yet so this also my first time hackintoshing. I have an old broken Mac Pro 5,1 from 2010 that I can't repair so I decided to imitate Linus Tech Tips by building a workstation Hackintosh inside it. I want more than 64 threads and as I've chosen to use two Xeons E5 26xx v4 (I'll define later the precise model) I want them to have Turbo Boost unlocked. The motherboard I'm thinking about is the Huananzhi F8D, a Chinese E-ATX motherboard. That brilliant guy made a GitHub repo with the EFI and a guide to reach what I want but with the 64-threads limitation. Is there a workaround for that? Thanks in advance

There's no workaround for the hard limit at 64 threads in macOS. Stop at a pair of 16C/32T CPUs, or disable extra cores in BIOS.

 

Note that for a first hack, you've set your target quite high. Modding the case to take standard motherboards will be a lot of work, and a dual CPU board from an old, now unsupported, generation is likely to give you some headaches.

and this is wellknown from many here (me and balamut talked in the past with pikealpha on this subject)

Yup, @fabiosun got a good memory. That was I think 7-8 years ago, I've managed to patch it in kernel, then went to the rabbit hole of kext patching from AICPU to two other kext if memory serves me correctly, but it was never ending battle, its integrated too deeply, at the end I just said screw it and just disabled few cores on each CPU.
