[Guide] CoffeeLake CPUs on Skylake and KabyLake mainboards

Using Asus z170m-plus and 9600k. Modded bios made by Coffee Time. All works fine. I can do only 4.6ghz safely because of the temp of vrm, but it’s totally sufficient for me.

Thanks to everyone who contributed to this!

Is this silver ink pen conductive I wonder: https://www.michaels.com/krylon-leafing-…cB&gclsrc=aw.ds

Thanks

Hey you guys do you think copper tape is best for splicing two pads together?

Used pencil and its working fine but for how long…

Thanks



Copper foil is better.

My Windows installation just became corrupted. Wasnt a fresh install. Had pulled the drive from other machine just to see if windows would work and was able to get in windows a few times but made a change to XMP profile and all of a sudden have an Inaccesible boot device blue screen. Going to have to reinstall. Possible auto settings not stable. Board auto overclocked the chip to 4.5 ghz. Probably next time going to have to manually dial in settings. Thanks.


Can You provide BIOS for Maximus VIII Ranger? Many thanks in avance



Try this:

(Microcode for 9900K and 6700K were inlcuded for sure, cannot remember whether Kaby Lake and lower core CFL as well. Check before use to be sure.)



BSOD during booting is normal for memory overclocking. I don’t think the system files are corrupted. Why would anyone write to the system files during boot?

Is the short next to the Bios chip on the Asus Max IX still necessary? And hows the VRM temps with the mono block and a good cooling setup?

No I don’t think it was from memory overclocking. My VID voltage values are like really low! Like 0.9 - 1.008 volts at 3600mhz fixed on a 9700k according to HWInfo and coretemp! Cpu-z is the only app that reports voltage at what I set it at wether it be 1.275 or what ever but not sure how to tell what actual voltage levels are at as I understand VID is more like the CPU telling the motherboard what voltage it wants and not what it gets. Little confused there.

Thanks

PS: Going to cross flash the bios of an Asus Z390-WS Pro onto a Z270-WS and study the effects if it works. If anyone has advice on performing that mod please do so.

1. Update VBIOS with settings from Z270;
2. E98D33CD-1AEB-46B1-A4B6-0BB4CC655C26 -Replace body PE Image with same guid from original bios;
3. BC327DBD-B982-4F55-9F79-056AD7E987C5 -Replace body PE Image with same guid from original bios;
4. 611F7FDD-C7C6-4CFE-8072-2155D7B25A80 -Replace raw section with same guid from original bios;
5. Remove GUID 63F23E9D-5FDA-415E-9C2A-64C4E2A6ECE8;
6. Replace codes after "PCI0.SLIC" within DsdtAsl module with those in Z270 which contains the SLI license;
7. Update Microcodes;
8. Update ME;
9. Replace main BIOS region in Z270 with the modded Z370 one.

Changing SKU is probably not needed on Asus Z270 boards. The FD already has it.



It’s not necessary if you can flash without USB Flashback. VRM temp is below 50 C.

Thank you so much for taking time to list out the steps but I just found out from Dsanke that because that bios is a 14nm bios its not backwards compatible, and because Asus didn’t make a Z370-WS not that I am aware of that wont be possible.

So right now I have a working Z270-WS Stock bios ver 602 modded with Coffee lake Tool however my VID’s are really low. Bios reports 1.008 vcore after reset and setting higher vcore only shows up in CPU-Z and HWINFO Vcore reading. Otherwise the VID volts are below 1.008 volts most of the time. Not sure how to fix…

Thanks

If you change anything to Vcore in UEFI, VID becomes completely meaningless. So just adjust your Vcore with basic offset, adaptive voltage and LLC (see my post in other thread) and be fine. 1.008 on UEFI is not far off by the way. This is at idle clocks without load, so a low voltage is acceptable.



Right now I have manual voltage of 1.275 volts set and bios reports its at 1.232 volts. So its a little low. Playing with LLC not make much of difference. If I set adaptive offset turbo voltage of 1.275 then bios reports 1.008 volts. Obviously I need to figure out how to manipulate IA AC DC loadline values. Will respond in other thread for the rest. Thanks.

Adaptive turbo voltage only kicks in when core ratio is higher than maximum turbo boost. 1.008 V is set by VID when core ratio is 40 in BIOS.

Would u pls guide me for modding Asus Maximus IX Formula?

I want to modding the VIII Ranger (bios 3504) to use 9700K. I do the following steps:

1. I run the coffeetime 0.83, 2. Choose the original 3504 bios, 3. choose 2 i7 9xxx/ i5 9600k, 4. choose 1 - autoupdate, choose 3 skylake/kabylake support, 5. choose 2 - unlock regions, 6. choose 3 - mac address, transfer mac address from this pc, 7. choose e - finalize, 8. choose usb bootable bios. 8, moding the cpu, 9. flashing the bios by usb flashing method. 10. insert the cpu and power on. Every steps runs perfectly.

Is this the right process? When will it support the new cpus :9700K R0 stepping, 9700KF?

Thanks

Almost except unless your board is fully unlocked to begin with your going to have to short two pins on your motherboard to allow unrestrictive flashing. May even have to rename the rom to creative.rom or something i think. Not sure about that.



It will probably only support 8 threads. Follow the steps in my post.

You can extract microcode from a BIOS that supports R0 stepping and insert it to yours with MMTool.
