@mcf you may have too many pins masked. It should be only two power pins, not four. See the picture in this thread:
Fixing PCI-Express for Coffee Lake CPUs on Sky/Kaby Lake non-Asrock(and some new Asrock) motherboards
And I had a much thicker layer of pencil on and between the two shorted pads. You have to get down to 300 ohms or so. I scraped the pencil over them, spun it in place, but I pressed very lightly. Pressing hard actually scrapes the graphite off the surface. It had to be rather thick, so the pads and the area between were basically black. Any lighter, and it did not work for me.
@Dnatwork if I have understood right those pins should be reserved and hence not problem. But there are so many details I have ignored that I must do some research.
@mcf in my experience (asus), with sktocc not grounded, system will not power up at all. ME caused immediate shutdown. I believe wrong SKU did the same, but maybe it was only no post. Not sure what missing ucode does (4c is 906eb while 6c is 906ea)
@oldirdey are you saying you donāt need to change sku to z370 if you clean the ME? I know I tested not changing SKU (with known good 11.6.xxxx ME) and it did not work. Changed SKU to z370 again and all is good.
@ziddey exactly. Maybe there are other ways to get 6 Core CFL working, but I only know these 2 Options. Even with vBios and GOP Update CPU will not post if SKU is not changed/ME cleared.
@mcf
In my BIOS, I have stripped ME (me_cleaner) and SKU changed to Z370. I donāt know if changing SKU only/cleaning ME only is sufficient and I canāt experiment now. But wrong microcode/pcie fix/vbios will let the board power on - it will probably not POST but the fans will be spinning/leds flashing. So in your case it is probably ME issue or 2 CPU pins not connected/shorted. On my ASUS board, turning power button without connected pins resulted in no draw of power from wall socket (no led on board turned on), with connected pins but wrong ME/SKU there were very brief (fraction of second) draw of power (and some led lighted up).
Hi!
I would like to buy a new, better motherboard instead of my existing b150m-ds3h type. Currently it runs with an i5 6500 processor and 2X4 gb 2400 ddr4 (with 2133 moboās limit).
I want a right card that supports my current processor BCLK tuning. And if I get a multiplier-free processzor later, then that too.
Also, later on I would like to keep the machine in the longer run, so it would be good if I could include the 8th (possibly 9th) series I7 processor in a new one with some mod. (as in the previous configuration: 775-771).
The amount for the mobo would be about 30000 HUF
Which motherboards are recomanded?
Z170 ones compatible with the i7 8700k with HT?
My old motherbord compatible with the coffee lake cpus?
Thankās for the help!

@mcf there is a whole section about Management Engine here in the forum.
Special: Intel Management Engine
@Martin97 I would recommend a z170 if you are planning to BCLK OC your current CPU and plan to OC your next. The Z170M OC Formula is the best of the best, but kinda expensive. The ATX version is pretty much the same. The Z170 Asrock Fatality Gaming K6 is what I personally have and itās such a beast. I managed to snap it up off Amazon Warehouse for 40 euros. You should look for a board there or off craigslist in my opinion. I wouldnāt pay more than 100 USD personally.
Thank you for your help.
Will the Z170 Asrock Fatality Gaming K6 supports 6 cores coffee lake cpus? Itās more inportant for me than the bclk oc.

With the mod done properly, yes.
Fine. Thankās for your help. 
I looked around the online market And I found them to be of a fair price:
ASRock Z170 Pro4S; GIGABYTE GA-Z170-HD3; ASUS Z170-A; ASUS Z170-E; GIGABYTE GA-Z170-HD3P; ASRock Fatal1ty Z170 Gaming K6
Or from the Z270 ones: GIGABYTE GA-Z270P-D3; ASRock Z270 Pro4; MSI Z270 PC MATE; MSI Z270-A PRO; GIGABYTE GA-Z270-HD3P; (Maybe but these motherboards are a bit expensive ones: MSI Z270 SLI PLUS; GIGABYTE GA-Z270-Gaming K3; ASUS PRIME Z270-P)
So what do you think witch is the best for me? Multiplier and BCLK oc, so i need a strong VRM.
And maybe someone can help me in the mod? Iām a bit beginner. Iām only make a mod for my old 775-771 system.
If you have money to buy a 8700K but not a z370 motherboard I think you have some issues elsewhere.
Do not harrass people here with your spamming request (all your 7 posts here) asking for help for something you still not have and not understand.
Thanks
Iām sorry for spamming. 
My current motherboard is dying. Now I can only afford a new motherboard.
Later, I will buy a new processor (if i have the cash) for my new motherboard. And i wouldnāt like to buy a new motherboard again.
I will buy a z170 motherboard and thatās all. Thankās for the help again.

hey guys. Following the aforementioned steps to add/update CPU micricode of AMI Aptio 5 BIOS. I hit a wall when updating GOP driver of my BIOS using UBU.bat tool. Getting an error stating āfunction called with invalid parameter.ā Anyone got any ideas or solutions to help with this error?
I am using the most recent (v1_70_rc5_2) version of the bat tool. All prior steps to update the VBIOS have completed successfully.
I think this question is relevant to the current thread but I apologize in advance if I shouldāve started a new thread for my issue.
Get the GOP GUID either from UBU or find it manually in UEFITool or MMTool and extract and replace in MMTool or UEFITool
In either, be sure you put back same way you extract, and be sure to extract so that the file matches how the new one looks in hex (ie first line looks same, header there or not etc))
Has someone tested a ASRock Fatal1ty Z170 Gaming K4 and can report how it worked out? I could get one for cheap and would try the mod for fun :). I would like to test one of the 6 Cores like the i5 8400 or the i5 8600k!
so iāve extracted the GOP from the bios with MMTool but what do I replace it with?
Subtype GUID: 380B6B4F-1454-41F2-A6D3-61D1333E8CB4
hold on, I went to the forum page for intel efi and gop drivers and downloaded the latest update and im using that.
Work in progress, bear with me. I am unable to update or change my microcodes with the UBU tool the same way it is outlined in the guide. However I tried adding microcode files and now im stuck with only one cpu microcode instead of the two I had. Im trying to figure out how to change one and keep the other but there is no option to do that.
on the GOP, you have to open each in hex editor before you replace. If first line does not look similar (header) then you may need to remove it or add it etc.
How you extract is what you need to check, because you will put back that same way, if there is header when extracted then file you insert needs header too, if none on extract then make sure none there on insert.
On the microcodes, it may be due to one is no longer used (ie both combined into new one). You can also do that exchange with MMTool probably too, delete one, insert itās update, delete the other, insert itās update, done.
If you are confused about the above GOP stuff I mentioned, please upload your BIOS here, along with the GOP you want updated to BIOS and I can do for you, or better explain/show you with images what I meant.
