Which CPU microcodes do you need to insert to ?
Coffeelake ofc !
Use EUFITool, extract the microcode file body, edit via hex, reinsert body. Then correct FIT via similar method extract (As-is, not body), hex edit to correct, then reinsert as-is, not body
I would have done the mod for you as I replied here, but still donât know what microcode you want added. Please specify exact microcode you want inserted, not CPU general model name, if you are unsure give CPUID for exact CPU model
I want to add the microcode 72, just want to put i3 8100 on this board 
hi.
I cant get line of "update cpu microcode skylake".
mb msi h110m pro-vd and i3 8100.
@sickyturtle - Which microcode do you not need anymore, one must be removed due to space constraints. 506E3, 906E9, or 506E8
@470m1c - this thread is about getting rid of skylake 
Be specific, which CPU Microcodes do you want in BIOS, list them all, and I can do for you.
Also, same as above, please note which one you are OK with removing in case one needs to be removed.
Hi!
I have your own motherboard (asus impact VIII), could you post the bios you used?
Unfortunately, I have the latest BIOS version (3801) is a problem?
Did you have to do anything special besides what is written in this guide?
Thank you!
M8I modded bios:

Comments:
1) Flash with SPI programmer not bios flashback
2) Before flashing use F44Editor to fill in unique board details -this step is not compulsory
3) 8700k will probably require HT to be turned off to boot
4) make sure to do good job on isolating 2 pins + bridging 2 pins - Kapton tape + electrically conductive tape is recommended
Can you re-upload this file?
Thanks you
ok then remove the 906e9 and any kabylake cpu related since I dont have any kabylake cpus. Thanks alot !
Thanks for the reply back, here you go @sickyturtle - BIOS only contains >> 506E3 - C6 / 506E8 - 34 / 906EB - 72
thanks alot !
maybe I will need to try to do it myself so next time will not try to bother u xd
Seemingly the pencil trick didnât work in my case. I have tried to get i5 8400 work on my board but always when I push the power button the fans just try to start spinning. The ME version is 11.6.0.1126 and this mod bios works with i3 8350k. I have also updated the microcodes, of course. Maybe there is some kind of conductivity problem between the âshortedâ pads. I used several 8b pencil though.
probably ME issue, see post #367
How could this be a ME issue if everything works with my i3 cpu? The resistance between the shorted pads was about 100 000 Ohm.
I tried again with the cleaned cpu and the booting experience was same.
@oldirdey I know that but it can be a shorting issue too (the post #162). Maybe I have to test some kind of copper tape / conductive ink. I didnât change the SKU, but that shouldnât prevent the board booting?
@Dnatwork did you try to boot your system with failed cpu shorting? If so, was the reaction similar compared to my case (#392)?
@mcf at first I didnât know I had to short those two pads, so the fan spun up momentarily and shut off. I used a 2B pencil to short the pads. The first time it worked great probably 200 ohms), but then I changed the fan and did something to the cpu, and it stopped working. I had to try several times to get the resistance back down low enough to work. It would not work at 500 ohms.
If you really meant 100,000 ohms, thatâs way too high.
Some people say to use conductive ink. Silver is best, carbon should work.
I have an ASRock H110M board. If yours is some other brand, they probably set it it to work with a different amount of resistance.
@mcf yes, if 6 core is used than you need to clean the ME or change sku to 370, otherwhise it will fail to post. The sympton is the same as not shorting the pads. read post #367 from s.napi.
Try to get some conductive tape. It´s much more reliable then the pencil mod.
@Dnatwork this is an Asrock board (H110M DGS R3) so maybe the problem is too high resistance between the pads. Whatâs the ME version you have used?
@mcf I have 11.6.whatever. It came with 11.8.5, so I had to downgrade it using gnu grub according to the post by @MOB. I canât remember the number, but someone just quoted it above. If you need that, also look for my response where I gave very detailed steps to make it work. Maybe you donât need them.
Someone just said to change the SKU to Z370. I did that because I was told to, and it made everything work very badly. USB was flipping out, system kept hanging. I reverted to the first BIOS mod I made (using BIOS downloaded from ASRock site, dated October 2017, and I think microcode 72 for the i7-8700), and all problems went away.
I suppose one problem could be if you have the wrong microcode, or a newer one that Intel has updated so it wonât work on old boards. (I know thatâs what ME does, but I donât trust Intel.) I had difficulty finding the right microcode for the 8700, and there was even less info available about the 8400 when I was looking in March. But they should all be available now.
