I want pair new CPU 9600KF with Maximus IX Extreme. I looked all over the internet, but I cannot find SKT_OCC pin or guide to use this CPU, can you please help me a and show me the way? 
Have somebody did it on this MB and could give me short overview - HW mods and SW mods what I need? I dont want to modify cpu, I prefer to modify MB instead, but I am not able to find Nuvoton IO chip for SKT_OCC pin location. I am so desperate, that I will gladly pay for guide 
I have the same configuration as you do but as vast majority of people I went for CPU modification since CPU mod is easier to reverse. As for your question - I have not seen SKT_OCC for M9E either but I have seen this mod for similar board - M9F (Formula), you can find it here
[REMOVED - Your posts contains to many links. A maximum of links is allowed.]
I think there is very good chance this would also work for M9E as chip looks the same for both boards. Of course this is on you if something goes wrong … well you know.
PS I’m not allowed to put direct link to YT video!?! Strange so got to YT title is "How to run a Coffee Lake CPU (8700K/9700K/9900K) on Z170/Z270 Motherboard, 2020 Update" and at 9:20 author discuses how to do this mod.
Can’t vouch vor M9E, but when I worked with M8R I checkend onboard-mods from M8A and M9F and despite finding a similar row of contacts on M8R, I did not find a connection to SKTOCC pin. So be careful when adopting mods from different designs, not everything is c&p on Asus.
I have tried a few different options in the Coffee Time 0.92 tool, but I still can get mine to POST -it still restarts 8 second after powering on but before POST. Does anyone have any ideas as to what it causing it to fail? I have tried 2 different PSU units, with and without GPU attached (no hard drives attached.
Anyone have any ideas or anything I could try?
Regarding the pencil mod (connecting to 2 contacts) on the coffelake cpu, do I have to pay extra attention for the pencil not accidentally mark the other contacts? Are all the contacts at the side of those 2 pins used? What will happen if the pencil carbon touches those other contacts?
I have my i7-9700 booted and working fine on my ASRock Z170 K6 motherboard (a million thanks to everyone). But I’m not sure if I should be extra worry about the pencil mark.
Better stick to connecting AB35 with AC35. AC34 (“above left”, when CPU is positioned with A1 corner to the lower left) would be Ground as well, but the upper right (AC36) is DDR_VTT_CNTL, likely disrupting RAM recognition, to the direct right (AB36) is PROC_SELECT which probably has no function in a single socket system, but won’t give you the needed short from AB35 to ground. If you connect to AB34 (“left”), AA34, AA35 or AA36 (whole row below), you might frag parts of your VRM as these are VCCGT.
25% success, 25% indifferent/most likely no boot, 50% could be damaging. I am acutally not quite sury what happens if you connect SKTOCC to some powerplane. SKTOCC in itself is also a positive voltage pin and has hardly anything behind it except a low voltage drop out and sensor. If that line is tollerant to 1.3 V, conecting it to VCCGT would be just another “nothing happens” mod, causing no damage no matter what you do with SKTOCC. Starting out with the wrong pin however can get you into trouble: Connecting AB34 to AC34 instead of AB35 to AC35 would short VCCin to ground which might cause some fireworks as this hat the potential to cause a rouge flow of well over 100 A on some oversized high end boards. However such as mistake would imply leaving only one row of contacts between your mod and the contact free center of the CPU instead of the indendet distance of two rows. If your math is so bad that you cannot spot this mistake before installing the CPU, you should perhaps lower you expectations for your PC’s calculating speed as well. 
Your link btw is carying a fake title. AB35 is in the upper part of the shown CPU, the least damaged area. Most likely area to be damaged would be almost intact upper right, where Gigabyte and allegedly Biostar boards require extensive isolation. Left hand side does show some damage and has some isolation recommendations, but the pattern of damage and endangered contacts does not match and the board in the background should be a Strix Z270, which to my knowledge does not require any isolation at all. (the precursor Maximus VIII Ranger can definitly be used with just SKTOCC). But it does require SKTOCC mod to supply a CFL with power at all and the shown CPU has not been SKTOCC modded as can be clearly seen. The most grilled parts on the lower end in that picture therewhile are VCCSA, parts of one DDR-channel plus the neighbouring DMI and PCI-E section. So someone really blew out the I/O are of his CPU here, but there is no relation to 1151 (CFL) to 1151 (SKL) modding.
Actually I am kinda disappointed that Ian makes such a lapse on his twitter as he usually is extremely well informed about Intel tech.
That was a lot more answer than indended, guess I should go back to work
I need bios mod Meg Ace z390 7B12v1B1
Can you share me?
@svarmod , just a small message to thank you for your CoffeeTime application. It works really well and looks very polished. The tooltips were also most helpful to me.
Today I replaced my old i5-7400 with an i7-9700K in my good ol’ Asus Z170i Pro Gaming. I am a happy person :-). Cheers!
Hey folks, I’m trying to get a 9900k to work on my ASUS Z170 Sabertooth Mark 1. So I modded the 2202 BIOS with Coffeetime and flashed it with usb flashback on the Mainboard, I have done the Pin short and Isolate on the CPU.
But my problem is that it wont boot, nothing happen when pressing the power button.
Can you pls help me to find a solution?
My modded Bios: drive.google.com/file/d/1TPvJleZ3UX1O9KseINfqdN8wlPTV69_R/view?usp=sharing
My pin work: drive.google.com/file/d/12KvAxliN2wd9IjGljG2PeFM7JfwSYV2Z/view?usp=sharing
EDIT: Okay folks I got it, after redoing the pin short with silver paint for the third time it bootet 
Hi! Can you please help me with my M8i motherboard? Im currently using 6700k and would like to use a 9900k.
Is there anyway you can help me please?

You should be able to mod a 2202 UEFI with Coffee Time and I think there are even some more advanced/specialized mods done by hand cirulating for the Impact. But you will most likely need a CH134A flasher to read out your current chip and flash back the mod as almost all ROG Z170 have a locked descriptor region. At least I would not know how to perform an temporary unlock as the traces chosen by intel for this are part of the audio interface and getting at the contacts of M8Is audio codec during boot-up would be a very special challenge.

- Added 16-threaded CPUs support for any s1151 22nm boards (method provided by @dsanke ).
- Added fix to remove “ME abnormal” warning on MSI boards with disabled ME. (also by @dsanke )
- Added fix for Clevo Z370 with disabled ME to bypass auto shutdown. (also by @dsanke )
- Added possibility to setting up boot RAM freq to 2133 (may be usefull to starts high-freq RAM with 1440 CPUs).
Enjoy!

Is this as gerat as it seems? 16 thread support with any board AND any BIOS? Asus beyond 2202?

Exactly.
ASUS 100 v3xxx, ASUS 200, MSI 100/200, Biostar 100/200, ASRock 200, etc - now all boards can use 8/16 CPUs w/o restrictions.
This makes 100 series timeless. i9 9900 is enough for next few years.
