i always used samsung in the past
960 pro
970 pro

but this time i went with pci-e 4.0 and since i was building an aorus system

i also wanted the drives to be aorus

i know my board is only pci-e 3.0
but i get a bit faster writing speed by using pci-e 4.0 instead of pci-e 3.0

i think the 970 pro was only 2.2 writing speed

which in most cases might drop down to just 2 gbps

but by using a 4.0 drive on a 3.0 board, i get 3.5 in writing speed, it seems like 3.5 is the max, the pci-e 3.0 4x can handle

the good thing is that now my reading speed and my writing speed

both are at 3.5

instead of 3.5 and 2.2

the down side might be that my drive might not be supported on mac os

i had that idea on the back of my head when i ordered those drives

i will find out soon enough
if the drivers are compatible with mac or not

this was the last time i was running mac os until mr cook decided to ruin everything
Interesting
What is the brand and model of your PCIe 4 M.2 drives ?
EDIT
is it this one ? :

yes but the 1tb version
i have 4 of of them installed on an aorus card
i also have another aorus card and i was planing on buying 4 more m2 drives

the video i uploaded, i was using 8 samsung 970 pro in raid0 with 2 rocketraid 7102 cards

that was the last time i had my hackintosh running, then mojave came out and no support for nvidia, the rest is history, then after almost 2 years i decided to buy an amd card just to run mac os, even if i had to switch cards to game on windows

but now after i updated to the x299x aorus master there is a new problem with the board, i honestly haven’t tried to install mac os because i been super extra busy

but i think all i need is an extra week to finish my home project, then i will try installing mac os again

a few users had reported success with the x299x aorus master

my only doubt was the drives because those drives use a new m2 controller,
i don’t remember the name but i’m not sure if the controller is support it or not in mac os

i just ask because i didn’t want to waste time, but i think once i try to install mac os, i can easily find out if the drive is support it or not

thank you

thank yoy
thanks for the answer

EDIT
I finally buy one
I placed it in M2 PCIe gen3 4x
Number are impressive with HFS+ format :thumbup::
capture 2020-10-01 à 14.52.57.png
capture 2020-10-01 à 14.52.03.png
As impressive as the weight of the heater :lol:

The numbers goes down to 500 MB/s with exFAT format.
Any explanation ?

I followed @dolgarrenan instructions on his original post, Section 6.
Disassembling the motherboard is not complicated, but you need to keep track of all screws and where they came from.
I used this magnetic pad to keep them, marking it's areas with included marker:
https://www.amazon.com/dp/B00Q2NUXD8/?tag=tonymacx86com-20
I printed motherboard pictures from the OP to number and track screws.
Naturally you don't want to use any force as the whole pipe assembly detaches nicely after all screws are removed,
I did it without removing my huge CPU heat sink. I don't recommend this because you can't turn the board upside down and expect it to be stable.
Assembling back, you need to make sure everything is seated exactly like it was before. Otherwise it will overheat and die. I won't be responsible for any damages.

For the programmer part, first, I bought this programmer:
https://www.amazon.com/gp/product/B07SHSL9X9/?tag=tonymacx86com-20

Instructions:

I tried it on a non-essential motherboard and it worked, but, while it can provide 3.3v UCC to the BIOS chip, signals are still 5. I didn't feel like unsoldering a pin on programmer's chip and decided to take a RPi instead. I had RPi 3B already, so it was an easy decision. Mind that you still need a clip to connect to the TB firmware chip.

Here's a mini-guide on how to turn a RPi into a programmer, which I used:

Overall it was easier than I expected, but I came prepared, reading instructions and allowing enough time.
You really want to program the firmware only once... no, let me rephrase: you really want to disassemble and assemble back your board only once. Especially if it's already mounted in a case.

Good luck!


@teosoft Thank you for all that good info. Looks like I don't have a choice but to get dirty on the motherboard to get thunderbolt working. Was this a complicated process? Could you please point me to the programmer and all accessories you used so I could follow suit? I see the following: https://www.microcenter.com/product/460968/3_Model_B?src=raspberrypi

Do I need to purchase seperate cables/accessories to go with it?

Lastly, I was never able to get the OP's SSDT's to boot past the apple logo screen, yet boot works with with opencore's prebuilt SSDT's. The OP's ssdt's would load extremely slow and never complete. You think this issue is bios settings related?

I'm always happy to help. I believe the clip is available separately but the programmer comes with a number of other goodies you might find useful later.

One more advise? Try to be at your middle level of confidence :)

@teosoft Understood. I am feeling brave. Thank you for the wealth of information. I will be ordering the rpi programmer and the the programmer you iniatially purchased so I have the clip ready. Seems all should be fine long as I am organized. Will update with results once completed. Appreciated.

Did you manage to make it sleep? Mine doesn't even try :(

I have my RAM running at 3200 and I see as much on "About this Mac" and in "System Information, Memory" as well.
I'm running OpenCore 0.6.1 and I just upgraded to 10.15.7


Allright, it looks like i have everything working the way I want it. Only one odd issue:

My bios has the xmp profile enabled and shows 3600 mhz (my max ram speed), but once macOS loads, it only displays the RAM speed as 2133mhz. This is not an issue I had a couple weeks ago. Anyone know if there is something else that needs to be changed in the BIOS for it to load at max ram speed properly? No idea why it's doing this all of a sudden.

I, like yourself, just enabled XMP.

Can you post your EFI folder so that I compare it with mine? Mine never went to sleep; the display goes dark but I see lights on the GPU and on the motherboard, and the fans spin. None of which happens in the proper sleep state.
It also might be a BIOS setting.

The restore you did likely brought back the kexts that you did not have before restoring. If you were to do it again, i.e. from a fresh install, you could've restored it *without* System folder but then some of your plugins and apps would not work.

@teosoft what did you do to make it run at 3200? Just enable XMP profile? If so, that literally does nothing on my end. Show 2133mhz regardless.

So on my end, I restored an actual Mac backup from my 2013 mac pro. That's what is running on my opencore disk.

Regarding sleep, I just went to make it sleep via the apple logo>sleep and it slept fine. However, I didn't hear the computer hardware actually sleep, so i'm not sure if it's actually sleeping or not. Otherwise, my hardware seems to stay on like yours as well.

With all this said, sleep did work properly, along with my ram speeds weeks before I did the restore. Perhaps if wasn't using this restore, both would work fine again. It is not something i'm willing to do though as I have way too much data and software plugins (6 years worth) i'm not willing to reinstall.

Hey, @teosoft!
I did not have the time to write for the last couple of weeks. Sorry for that. My system is really sleeping. It takes a while till everything shuts down, but it does. Wakeup by pressing the power button or a key on the keyboard works: the fans start to spin and LEDs light up. But the screen stays black and it seems that I get a kernel panic at that moment. Unfortunately, I can't find a real log with information on what's causing the crash.

I read in Big Sur threads lot of people saying that it fixed sleep issues without doing nothing. Let's hope Big Sur fixes this random behaviors. I cannot test it as still I am very far away from my hackintosh and since we got the bloody Bios Failure I cannot reboot it.

Hi all

I'm shortly going to be buying my first new PC in 10 years. I've saved up some cash to get a pretty decent system, hopefully to last the next 10 years.

I first thought about AMD Threadripper, but then I learned that there are compatibility issues with various apps, requiring special patches. I really don't want the hassle of maybe finding a key app won't work, or having to wait before I can update an app until someone has worked out the right patch. So I'm going to stick with Intel.

I'm looking at Intel 10980XE, 128GB RAM (3200 or 3600, 4x32GB) on the Gigabyte X299X Designare 10G. I particularly want Thunderbolt 3, and the dual 10GBe will be useful too once I switch over my network to copper 10Gbe (currently I'm using Intel X520 10GBe NICs on fibre). Iniitally I'll run it with my existing AMD Vega 64 8GB GPU, but later hope to get one of the new Big Navi cards when they're out and supported by macOS.

Before I spend a boat load of cash I just wanted to check that you owners would generally recommend this motherboard? I've read the first post and most of the last 10 pages. Seems that people generally have things working pretty well? I know that I'll probably need to flash the Thunderbolt firmware to get fully working TB3, and I'm willing to do that. I already have a Raspberry Pi, so I'd just need to order the ROM flasher stuff.

It'd be good to hear from someone who has this motherboard in their Hack to confirm whether you'd buy this motherboard again if you were in my position?

Thanks in advance
