@davidm71 : Pin shorting is actually named correctly and meant to short the pins the socket, not the pads on the CPU. For some (Asus-)motherboards there are even onboard mods which short the traces leading to the pins, so no mod near the CPU is required at all. Shorting the pad is just an easy way to achieve the mod independed of board, but tape with a conductive outer side is completely suitable even if the lower side is fully isolated due to adhesive. Mind though, that there also copper-looking tapes available which are meant for pure decoration and might be (almost) nonconductive on both side.
Personally I used conductive silver which I had sitting on the shelves from old Athlon and some GPU mods.

@PCGH_Torsten Well taking an ‘If it ain’t broke..’ approach. Decided against it for now.

Hello I have Asus Z270I Strix that i wish to run i3 8100 on. I modified 0814 bios with Coffeetime but I am unable to flash the file to bios .

The flash utility in bios says its not a valid bios file and fptw says "Error 318: The host CPU does not have read access to the target flash area. To enable read access for this operation you must modify the descriptor settings to give host access to this region.
FPT Operation Failed."

I previously had MSi Z170 board and didnt have this problem. Is there something special I have to do with this Asus Z270 board?

This is BIOS-lock feature from ASUS. Described below appliable only for B0 Coffee (i3-8xxx etc).
Check actual ME version on your board by Intel ME Detection Tool.
Three options exists:
1) Your ME is already between 11.6 - 11.7 and it's ok.
In this case you need to reflash only BIOS-region from modbios.
Just use AFUWIN 3.05.04 for flashing, it will help to get around ASUS BIOS-lock problem. Command: afuwinx64 modbios.bin /GAN
Or disable BIOS-lock first and flash with FPT then. Command: fptw64 -rewrite -bios -f modbios.bin
2) Your ME lower than 11.6.
Update ME to 11.6 - 11.7 version by any official method, then go to point 1.
3) Your ME 11.8.
Use SPI programmer to reflash bios fully or try to unlock regions by HDA_SDO and then flash full image with any software tool.

@svarmod Thanks for that detail though I thought that there were certain regions besides ME that needed to be modded and unlocked which is why you either do a flashback with shorted pins or use a flash programmer. As far as unlocking the Asus bios locks this guide helped me: [GUIDE] Grub Fix Intel FPT Error 368 - BIOS Lock Asus/Other Mod BIOS Flash

Also, changing subject, on my modded Asus Z270-WS board I have noticed lately lower voltages and Asus running a 4.5 ghz profile on my 9700K. Was kind of confused because I thought the 9700K runs at 4.9ghz Turbo. In any case I believe I understand what is going on with Asus and its Multicore Enhancements feature. Turning that feature off brought the max speed reported in bios up to 4.9ghz. Not sure if the voltages were corrected by turning it off however I think the bios misidentifies the 9700K as a 7700K as does other apps such as old version of CPU-Z and Coretemp and others as the 7700K turbo speed is indeed 4.5ghz.

So I think this is whats going on when I set 1.275 vcore and I get 1.225 is because that 1.225 volts is what is appropriate for 4.5 ghz and not 4.9 ghz in consideration of an i7 7700K profile loaded in bios. According to the bios description even turning off Asus Multicore Enhancements loads Intel's defaults for that cpu which is probably what I want though not sure if the board can handle all the watts. Maybe it can I don't know. So fwiw I have turned on in bios VRM phase control to 'Extreme' and cpu power delivery to 110%. Too bad we can't mod the built in profiles. Any other ideas you guys have please share.

Thanks.

No, 11.7.0.1229 is OK.
Use for flashing AFU 3.05.04 with /GAN param.

Hi, Any way to mod the BIOS for 9900K but no need for CPU pin mod? I am asking for an Asus WS-Z270.
Thx.

CoffeeTime 0.85a released.
Nothing special.
Added universal ME for Xeon, Vbios base up to 1062, updated microcodes, unlocked Xeon autoupdate for most of 200-series boards and added pretty nice experimental function for ASUS boards.
Full list in readme.txt
Download

" Shorted CPU pins may be replaced to soldered bridge near to Embedded Controller directly on board."

Can you point out how do that on Asus WS Z270?

Thx.

@Bruno,

I got a working bios ver 701 for the Z270-WS modded with a 9700k if you want a copy.

Just thought of a great idea for simplifying the physicsl part of the coffee lake mod. If we could fabricate a thin 3d printed plastic plate that would fit in the socket under the cpu matched in size and direction and dimension with the proper pads either splinted or blocked out you could idiot proof the modding process. No more rubbing pencil or applying copper tape or silver paint. All you would have to do is drop in the matching coffelake cpu modding plate for an msi, gigabyte, or Asus motherboard into the socket and place your cpu right over it. Only thing left of course be the software mod. Think this is a great idea.

@svarmod thanks for coffeetime. I just buy i3-9100f (stepping B0), does coffeetime 0.83 support it ?
and if coffeetime 0.83 support, which target CPU do I need to selected ?

Modded bios 2202 on for my Maximus VIII Formula using CoffeeTime 85a using a 9900k, isolated the pins along with connecting the two. My system just shuts off right after I press the power button. I added the Skylake microcode and my 6700k still boots properly. What might be the cause? Using the suggest 11.7 ME.

@WannaBeOCer,

Try using the other simple coffeelake modding tool instead. Also maybe its a bad cpu or the blocking out + shorting pins wasnt done right. Maybe you failed to write to all of your bios sections. If you do a bios dump check to see if all your regions are unlocked? If so then use the simple tool instead to make new bios and flash via fptw after fd44 transfer. If not use flash usb programmer. Then try again. Give system time to restart as it will post over several times. Also please watch what your LED post codes are?
