I don't know. It lists a lot of stuff. Are you using SSDT for USB? If not, I suggest starting there. Also, did you rename your dGPU to GFX0?

Yes to SSDT, posted above. The list of patches do not show dGPU to GFX0. Can you point me to that patch?

Please enter the following in Terminal and post the output:

pmset -g log | grep -i failure

Should USBInjectAll.kext still be in L/E when using an SSDT for USB?

probably would not work for my set-up but this is unfamiliar territory for me.

Well we have the same mother board, we have the same CPU, unless you need the one yellow usb and the built in wifi card I am not sure why it would not work on your setup. Do you have a setup that is not listed? I am hesitant to post stuff here since this is Pastrychef post and we have a different board then he does do not want to confuse the issues. However there is a post for our board if you make a post there it will signal me and I will post me EFI there for your review and use. Sleep works fine for me.

Wouldn't Whatevergreen do those renames maybe he does not need the GPU renames in clover.

Put all your hack kext in clover---->kext----->other

Yes.

Yes, it's supposed to, but it was discovered that sometimes it doesn't work so I have it in config.plist just in case.

I find that my GPU rename to GFX happens way after PEGP when I use WG and that if I do it myself it renames PEGP but where WE names GFX0 shows Display. I notice that when I do this rename myself in clover it causes issues with Movies on iTunes working correctly. By allowing WG to do it iTunes works correctly with IGPU enabled and plays movies.

Yes.

Thank you. Will see if that works.

To The Nines!!

My Rockit Cool Copper IHS arrived today and I finally have my i9-9900K installed.

Here's how it's running:
All cores 5GHz @ 1.310v
AVX offset = 0
Ambient Temp: ~25C
Idle Temps: 36C
Max CPU Temp: 83C (Prime95)
System power draw from the wall: ~312W (Prime95)



My old i7-8700K ran at:
All cores 5GHz @ 1.380v
AVX offset = 0
Idle Temps: 33C
Max CPU Temps: 80C
System power draw from the wall: ~307W

It's clear that the i9-9900K runs hotter than the i7-8700K. Although the numbers above show only a a few degrees C higher, the fans in my system run about 200-300rpm higher at full load. Fortunately, even with the increase in RPM, noise is still very manageable.

I think my delid job is very successful based on what I see in temps vs what reviewers reported. Also, power draw is very similar to that I got with my old i7-8700K where reviewers saw massive jumps in power consumption when overclocking the i9-9900K. The delidding was definitely worth the time and effort. I've done quite a few delids and this took the longest, by far. It wasn't "difficult", just more time consuming due to the method I chose to use for the solder removal. While I don't suggest anyone try to delid the i9-9900K, I do recommend getting it done. There are huge improvements to be gained.

Some reviews went as far as to suggest using 360 or 480mm water cooling solutions. I feel that delidding is far more elegant and I'm seeing better temps than what some were seeing with 360mm water cooling systems with far better power consumption with my little ol' Noctua air cooler.

Seeing as how almost all of the new Z390 motherboards have added power connectors for CPU power, I was a bit concerned that the Z370 would not be capable of delivering sufficient power to the i9-9900K. I'm sure that having a delidded CPU helps, but in my personal situation, power delivery to the CPU does not appear to be an issue at all. By the time I push my overclock to the point where power delivery is a concern, I would probably need a far more elaborate cooling system for the CPU.

I converted a video in Handbrake with my i7-8700K and it took about 4 hours. That same video converted in approx 3 hours with the i9-9900K. Times are approximated because I was afk when the conversions completed.

@corint1 reported that hardware acceleration was broken with the i9-9900K IGPU and macOS Mojave 10.14.1 and this was true for me as well. However, I fixed it by spoofing Coffee Lake IGPU. He also reported that macOS 10.14.2 beta fixed this.


I'm positive that my particular CPU has much more headroom for overclocking, I just have to find a good balance between power consumption, heat, noise, and stability that I'm comfortable with. I will mess around some more with this in the coming days, but, for now, I just want to enjoy the two extra cores. So far, I'm extremely happy with the upgrade!!


Update November 28, 2018:
Last night I decided to see if I could lower the voltage required to maintain a reliable 5GHz overclock. I'm currently at 1.290v with all cores at 5GHz and I just completed a 2 hour Prime95 run.
Update November 29, 2018:
I had to revert to 1.310v because, at 1.290v, the system sometimes didn't wake from sleep. Didn't have time to try 1.300v yet. Needed to get everything working for now so I could use the system.
Update December 1, 2018:
After lots of troubleshooting, I figured out what was causing instability. It was my RAM. Gonna have to RMA it...
Update December 21, 2018:
The RMA process to get my RAM replaced left me without RAM for exactly two weeks. I was victimized by the inefficiencies of the USPS. Anyway, the replacement RAM is working great. I was able to overclock my i9-9900K to four cores at 5.1GHz and four cores at 5.0GHz @1.310v. Idle temps are at 36C and full load (Prime95 testing) temps are 85C. I did not try 5.1GHz all cores because I do not want full load temps to exceed 85C.
