clear_me must be used before or after coffetime?
Guys, just a quick one,
Pls answer me,
Should I take this guide step by step to mod my Asus prime z270 a in order to run a 8700k or even 9xxxk?
Will it still be retrocompatible?
If so could you point me to the bios version to start with?
Thanks a bunch
I can do export for someone who will prepare me a bios. After downgrade the bios I have ME 11.6 do I have to use a programmer?
I can not use INTEL FIT
up
I have Asus G20ci h270, use coffe time and Revlaay automated tool for the mod and flash it with ch341a programmer, it works prefectly with i5 9400f (without cpu pin mod)
Then i purchased i9 9900k, but its not working, splash screen logo appear after swith on pc, but then just freeze, i turn off and turn on the pc again still the same, sometimes its just keep restart over n over again.
After all effort, finally I manged to get this i9 9900k working by disabling the hyper threading, so its only 8thread. Any idea how to make this i9 9900k work with HT enable?
Any help I ll be very gratefull.
llllllllllll
Hi i have an asrock z270 itx gaming planning in buying a 9400f for it. Do i need to buy a programmer? Any help would be appreciated.
unfortunately people don’t really help newbies here as I notice, they just tend to respond to hyper precise issues related to some “near death” experience while trying to fit cpus to their MB 
Even experienced users usually do not have tried more than 1-2 mainboards and CPUs. They know about technical backgrounds and can give advice on a specific problems, but they do not know whether specific problems are likely to occure with certain models. Even boards from the same generation from the same manufacturer, the same price segment and with almost the same layout can make a huge difference. Sometimes even the installed UEFI is important, because UEFI downgrade can be more difficult than an UEFI upgrade from a old board that has never been updated. E.g. I did not need programmer for Asus Z170 Sabertooth but for Z170 ranger.
One needs programmer when descriptor region is locked or when ME region is locked AND an ME too old or too new is installed or when one does not want to use illegal copies of UEFI flash tools AND there is no onboard flash function that does accept modded files. Only the owner can check which of these criteria do apply.
what about xeon E2100 series, they are also coffee lake.
Theoretical/technical possible and svarmod has integrated some Xeon options into the latest CoffeeTime, but I do not know how well they acutally work/anyone who has tried.
I’d love to run either a 8700k, 9700k or even 9900k on my Asus Maximus VIII Ranger (Z170).
I tried a lot with the All in one Tool as well as Coffeetime and both in combination without luck.
What do I have to do to get a working .CAP Bios out of the All in One tool? Since Coffeetime can make .cap files I thought I’d throw the .bin into Coffeetime but after USB Flashback the PC hangs at error code 31 (memory installed).
@Wolf_Larsen I saw that you have Asrock Z270 Gaming K6 with 9700k. What modifications did you do and how did you flashed bios? I’ll probably replace my 7600k with 9600k, but not until i’m 100% sure that i can modify everything without much hassle.
so am I, can’t find proper tutorial to do that, have you?
Hi all – I have an Asus Maximum IX Extreme that I’m trying to mod to run an extra 9700K I have on hand. I’ve done the pin mods (shorting plus isolating) on the CPU. I also used Coffee Time to build a 9700K compatible BIOS for my MB. I flashed the new BIOS using the Asus BIOS flashback feature and that flashback behaved normally. However, when I boot the machine I get a half second of power and post code “00” before it shuts off.
I also have a CH341A SPI programmer. However, I’ve been unable to read my BIOS chips (soldered) when I clip in to them. Anyone have experience with this board and able to provide me with some help? Thanks in advance.
@svarmod i gonna buy a MSI z170a gaming m3, i can put the i5 8600k only with two isolated pins from pin mod pic? No need short two pins for MSI mobo, right?

@ccassidy39 : I was able to read my Maximus VIII UEFIs with CH341A 1.4/1.31free Tools, but not with earlier versions. Beware of trojans, though. Post code 00 with a compatible 9700K UEFI suggest incompletely flashing, most likely descriptor region is locked.
Note that for some Maximus IX there are modified Maximus X UEFIs available. While the process to make these is much more complicated and specific, it is the superior solution if you can find a ready made version, as these UEFIs contain all coffee lake optimisations of a proper Z370 UEFI. (They still require CH341A of course)
Something with your bios, look in this side , just use early coffetime, just try

MSI Z170A_Gaming_M3 will not work with U0/P0/R0 Coffee CPU (8600K = U0).
It’s better to choose board from other manufacturer.

In most of cases 00 post = ME region not reflashed.
M9E normally works with 9700K.
- Update vbios to 1059 in Advanced mode of CoffeeTime by manual (required 1059+ vbios for iGPU in P0 Coffees)
- M9E bios flashes normally with attached clip. Make sure that you found right chip on board and clip connected correctly
- Use only v1.18 software for CH341A
- Completely match for bios chip names not required - different chars at the end of ID isn’t problem in most of cases
- Clear CMOS by button after SPI flashing

Unfortunately, M9E hasn’t bro from Z370 lineup. I tried make ports from all other Z370 boards (A, C, H, F) with similar VRM and they all partially works, even can boot in OS and work under load… But PCIe, USB and SATA lines has completely different configuration, so system didn’t work after restart.
