[REQUEST] Bios mod to get 8700k running on GA-Z270N-Gaming 5 (rev. 1.0) motherboard

I’m not very knowledgable in programming, I hope someone can help me get the bios modded to get my 8700k running on this board. Thanks!!

@mu7ashi - What BIOS are you using, and what is your current older CPU?
You do know you have to tape off the CPU on certain pads to prevent connection to socket, and possibly solder or connect with conductive paint/tape two pins on the CPU? You may not need to do the latter (connect two pads on CPU), but you can only find out by testing
If you did not know about this, please see here, section #3 >> 3.1 & 3.2 - https://forums.overclockers.ru/viewtopic…602278&start=60

Thanks for the link! Yes I had seen about the shorting of the two contacts, I’m willing to do it. The current bios on the board is F6d, current cpu is a 6700k.

You’re welcome! You may not have to short the two pads on CPU, I didn’t on two different older gigabyte boards (Z170N and B150N), so they probably already shorted SKTOCC to GND on Z270N too.
But, you will have to tape off (isolate) all the other pads on bottom of CPU shown in the 3.2 image labelled in RED For Gigabyte. Otherwise you can damage the board/CPU Socket and or CPU too.
This is tricky to do, unless you order one of those pre-cut stickers on ebay. It took me an hour or more I think I used kapton (Polyimide) tape, cut tiny “one pad width” strips and laid them in rows with needle tipped tweezers, the worst part is the large diagonal area
Or, you can also use clear acrylic, but that can get messy real quick

Thanks for info, I will work on BIOS for you and get back to you soon

* Edit @mu7ashi - Here’s is mod BIOS, this contains ONLY microcode for CPUID’s 506E3 and 906EA

Before installing Coffee CPU, you MUST isolate the pins marked in red at the 3.2 CPU image section of the link I gave you in post #2.
I assume you do not need to connect the pads on CPU (SKTOCC mod), test without this first, it’s probably not needed since it was already done on Z170 boards I tested (even cheap B150N)

With 6700K CPU installed, put BIOS on FAT32 USB at root (not in folder), enter BIOS and flash mod BIOS (Z270NG5.F6d.CFL-Sky1FIT.bin) with Qflash (If asked partial/fast or Full/In-Tact choose Full/Intact)
Reboot to windows, flash FD + ME with FPT from V11 ME System Tools using order and commands below

1. FPTw.exe -desc -f fd.bin
2. FPTw.exe -me -f me.bin
3. FPTw.exe -greset

After #3 above, be ready for immediate reset/reboot (automatically), so save all open files before this

Here’s how to use FPT if you don’t already know, it MUST be ran as Admin and you MUST use CMD not powershell


Go to this thread and in the section “C.2” download the V11 ME System Tools Package
Intel Management Engine: Drivers, Firmware & System Tools

Once downloaded, inside you will find Flash Programming Tool folder, and inside that a Win32 folder.
Select that Win32 folder, hold shift and press right click, choose open command window here (Not power shell).
At the command prompt type the commands given above one at a time, enter after each

If you are stuck on Win10 and cannot easily get command prompt, and method I mentioned above does not work for you, here is links that will help (I suggest just using the registry edit below).
Or, copy all contents from the Flash Programming Tool \ DOS folder to the root of a USB Bootable disk and do the commands from there using FPT.exe instead of FPTw.exe

Or here is simply registry edit that adds “Open command window here as Administrator” to the right click menu
After this, just select the folder that contains the FPTw.exe and right click, open Admin CMD prompt here
Double-click to install, reboot after install may be required
