Here is my EFi for the X299 Dark based on Opencore 0.6.5.

I had posted a detailed guide for @dny87 which actually took me a long time but unfortunately it didn't pass moderation! No idea why.

Thanks for all who helped me on this platform particularly Loloflatsix.

Good luck with your builds.

Ian
What are the cooling components of your system ? Did you delid your CPU ?

no I didn´t. CPU runs with standard clock, I haven't tried to overclock it yet.
I have an AIO water cooling system from be quiet (Pure Loop 360)

In case that question was meant for me I have the A r c t I c L I q u I d F r e e z e r II 240.
The CPUY is a standard i9 7980 XE - not delided.I toyed with the idea of deliding but knowing me I'd knock some resistors off and get liquid metal on the electronics .... and for me it really isn't worth the risk
Amazed at the over clock ability of this amazing processor though - and more amazing is the price - cheaper than a 10 gen 19 10 core and almost twice as fast (arguably) arrived in 3 days f'rom the east" and bought on a rather popular auction site :-0
I had the EVGA OC Robot feature overclock it to 4.4Ghz with a AVX offset of 2 for Cinebench R23 and got 24000+ - temps were maxing out at about 90 degrees though probably as a product of EVGA auto overclock. Haven't had time to manually weak the o/clock settings yet. Waiting till new Sam S b-die ram arrives and with that I expect I'll be able to get a lot higher scores with a manual OC configuration.

EFI OC 0.6.5 Asus Rampage R6EE :
- SMBIOS MacPro7,1 with CustomMemory.plist ( To adapt for other configs with appropriate USBmap.kext, DeviceProperties, Custom SSDTs ( GPU, Thunderbolt, etc...), Serial Number, SMUUID, CustomMemory.plist, etc...)

Try RestrictEvents instead of CustomMemory, works great! And no hassle for new users to adapt.

Be aware that benchmarks ≠ real world usage.

I wouldn't push the CPU that far. If you look at the intel ark site for 7980xe the t-junct temp is 94c, which is much higher than the 9980XE and 10980XE because they changed the TIM to liquid metal I believe.

It's best not to push beyond the 94c level, I would even try keeping it below that to make sure it has longetivity in the long term.

But definitely agree that these are nice CPUs regardless of what's happening in the industry with AMD etc. It should last us for a while (that is 2 years max since macOS is dropping Intel support anyway haha)....

Good advice. intend run at a modest overclock for daily use.

Yeah I just have a x42 multiplier on the 9980xe on all cores with custom waterloop and it still gets crazy hot. I set a thermal limit of 84c so it does throttle, but that's fine. It's still as fast or faster than a 28core Mac Pro anyway, so I'm happy for now.

Our time is limited with Intel though, which is sad. But hey, this machine made me a lot of money so won't complain haha. Haven't had that much downtime so far. *knocks on wood*

Delidding the 7980xe might gain you roughly -10c, might be worth it. I see delidded 7980xe's on ebay all the time, maybe worth swapping?

I've owned the 7900x, 9980xe, 10980xe, and out of all of them the 9980xe is my favorite because Intel added risk mitigations to the 10980xe and it actually runs slower than the 9980xe even at same clock speeds for some reason.

Interesting. When I bought the 7980XE - before it arrived- I researched delding. taking the lid off looked easy,...and even someone as clumsy as me could apply the liquid metal without spilling it...but what put me off was the removal of the silicon which holds the IHS to the processor. And getting that off looked really risky in terms of knocking off a resistor.... But I must admit the idea of deciding is very appealing and I'm sure that I won't be able to resist the temptation forever! 10C is a big drop. But I would do it myself, I'd want to be sure it was right.

Building a hack ticks all the boxes for me ...challenging, irritating, time consuming it certainly is..... but the problem solving, learning curve and the elation when it all works is quite addicting.Then you have a "Mac" that outperforms the real thing for a fraction of the price - and those multi core/thread Mac Pro's are truly astronomically pricey.

Remember that heat especially in these processors is exponential. Intel has really optimized their 14nm process, but it's hit a wall. The wattage is astronomical as you push it further and then you have diminishing returns and there is no point to overclocking further.

Also an actual waterloop is recommended for the 7980XE especially if you are overclocking, so the -10c was an estimation with an actual open loop cooling system.

Closed loop AIOs are fine, but they don't move water quickly enough so it's not a good solution for overclockers.

For me I have 2 priorities:
1) Silent system
2) Speed

The 1st always is an issue because the quieter the system, the lower your fan/pump speeds are. So I found personally a perfect balance of performance with overclocking and silence with custom fan curves in the BIOS which took me many days and hours through trial and error (that's why it's painful for me to reset the BIOS ever, but I am able to save the BIOS settings as .cmo files and I can restore when needed).

I really think people need to stop benchmarking their computers. It's cool and all, but what matters is WHAT you're doing with your computer.

Anyway, PC building for me is finished anyway, I barely ever have time to troubleshoot, so most likely this is my last Hackintosh. At least I went out with a bang :)

I MAY build a Windows machine but it will be a small SFFPC with maybe a 3080 for not so often gaming. My main machine where I sit at every single day is 99% of the time a Mac, so very much waiting for new M-based Macs that are for higher end desktop users.
