[Guide] CoffeeLake CPUs on Skylake and KabyLake mainboards

Please, open your output modbios in CoffeeTime again, but now in Advanced mode and update vbios to 1059 (only this one).
All P0/R0 Coffee Lake CPUs (it’s most of 9xxx) requires vbios 1059+ to work iGPU. But v0.83 update vbios to 1054 in automode. I’ll fix it in next CT build.
Using SPI programmer for flashing - best way to get success.

Found a bug maybe with the CoffeeTime utility. When I tried to mod the bios of an Asus Z270-WS bios ver 701 it failed to change the SKU for some reason.

Heres the file: http://www.mediafire.com/file/mv4valb2l4…S-ASUS-0701.zip


Despite that I was able to mod that version through other means. Just wanted to share the file fwiw.

Thanks

If you used CT_0.83, than it’s ok if SKU wasn’t changed.
Some time ago SKU changing was replaced by SKU-hack.



Thats interesting. It just made me worry when I saw the error. Anyhow got it up and running. Thanks.

@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 ?

I wait for the 9700K R0 stepping, so i have time until the updated coffeetime release. Hmmm EFI programming, i never do that earlier. The usb programmer is not so expensive, but i think to order a new bios chip from ebay, and the seller programming for free, and i have a backup plan, if anything goes wrong.

Thanks for using CoffeeTime. :wink:
A you sure if 9100f is exactly B0? All photos i saw in net shows that 9100f has U0 revision.
Anyway, you can recognize revision when cpu will be on hands using image of revisions comparison from CT.
For 9100F-B0 (same as i3-8xxx/G5600) choose "5" in CT_0.83 main menu.
For 9100F-U0 (same as i5-8xxx/G54xx) choose "4" in CT_0.83 main menu.



Most/all ROG seem to be locked, my Ranger was definitly, so unless you know an unlock-pin-mod for that board (I couldn’t find any), you will need SPI-flasher. For old steppings this process worked, including 16 thread operation if you want to go beyond 9700

so I need an efi bios chip programmer (like: LCD Flash SPI USB To TTL 24/25 Series EEPROM CH341A BIOS Writer USB Programmer) to overwrite fully the bios chip, with the cap file, which is generated by the coffeetime. I see now.

Capsule restoring required only for ASUS USB Flashback flashing method.
For SPI programmer you need to dismiss capsule restoring at finalizing and use .bin.

I wish we could flash bios and run, don’t need to pinmod in any stepping :slight_smile:

Hi,

Just bought copper tape and was testing the under surface of the tape for conductivity considering theres adhesive which is not conductive and noticed that I had to press hard with my probes to get a reading.

So wondering if the pencil mod is working for me why bother and does that adhesive cause issues?

Thanks

Do u have any modded bios for Asus Maximus IX Formula?

Where did you get the M10E bios file for flashing?

You can mod the original bios file with coffeetime 0.83, and flash back to the bios chip manually by an efi programmer, like ch341a. This is the safest method. You can order a new bios chip on ebay for 15 usd with the moded bios (sent by you). It is a safest way: switch the bios chip on board manually, you cannot bricked the board this way. Read back the forum little, and it gets clear.

@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.
