@JayCar - few things here, first, maybe regular pencil mod is not good enough for connect. What happens when you try to power on with Coffee CPU?
It's possible you may need to flash in mod ME FW (update to 11.7 via AIO Tool, then extract ME FW region and flash it in with ME FW update tool)
You may need mod FD flashed in as well, I am not sure when this is required and when it's not, ie what CPU's it is a must for and which are OK without mod FD flashed in.

Best bet is to get programmer and Flat Type IC chip puller if your BIOS is in a socket, or SOIC8 test clip with cable if BIOS is soldered to board.
Or, do pinmod (E.1 here) to dump FD with FPT and then unlock FD (via section B, spoiler two, image 1-2) then flash back mod FD, then all can be done with FPT
If you do pinmod, do not reboot until you've flashed back in unlocked FD with FPT, otherwise you will have to do pinmod again

I am not familiar with using the tool you mentioned, I prefer to use other one instead (it breaks BIOS less often, does less unwanted things etc, but I still only use it in advanced mode and skip microcode edit because it breaks BIOS too)
But, you should not run BIOS through two exe's anyway, AIOTool.exe will do it all from right there.

You should not have used stock BIOS for this process, due to the way you were flashing. Do you have ANY BIOS backup from before you did anything, can be made with ANY tool at any time in the past?
If yes, send to me, I will make you mod BIOS that should work properly, and will have your system details back in there too.
What is your skylake CPU model? For my reference later 8600K - 906EA U0

Hi Lost_N-BIOS, thanks.

When I install the coffee CPU, the mainboard lights up after power on, then immediately (~0.5 sec) turns off again. So it looks like it's hardware related and the board does not recognize the cpu?
Today I re-connected the 2 pins with even more pencil, but I can still measure 1.6kΩ resistance between the two pins. So maybe they are not shorted enough, as you wrote.

Any other methods to bridge the pins, if I don't have silver conductive paint in my shop?

@JayCar - Yes, it may just be that, not sure how much resistance should be there, I assume none once connected. You can tape off all other pins, and drop a light dab of solder in there, if you know how to solder good.
Otherwise you need heavy lead pencil (still not ideal) regular 2B pencil is not good enough, conductive paint pen, or silver or copper conductive tape (like thermal window strip repair tape). You can probably find conductive paint pen in your town at craft shop, or conductive tape/strip at Auto Store.

Or, if you google around your board model, and or look at other similar Asus Z170 board models, you may be able to find the SKTOCC hard mod to modify the board instead via solder/wire to ground etc
@revlaay @svarmod @dsanke @haru_ @Chinobino @PCGH_Torsten - - Do you know if there is SKTOCC hard mod for board publicly known for Asus Z170I Pro Gaming

I do not know. But I would guess not. Routing the trace to some easily acceassable place does require space and that obviously comes at a premium on ITX. Even if there are coressponding pad somewhere, it is guaranteed do be very close to other contacts, requiering very high soldering skills to properly mod. Just conductive paint/tape/glue/pen. With the right shops around that will be definitly faster and more secure in all cases.

Alright then, I'll order some liquid silver paint, will try again, and report. Thanks.

Lead pencil worked for me.

@Lost_N_BIOS I received the silver paint and re-connected the two pins, but it still won't work. The board shuts down immediately. I checked the resistance between the two pins and it's nearly 0 Ohm. So let's say my issue is something different for the moment.

I even tried Coffeetime as a 2nd CFL tool for modifiying my bios (with beta option: injecting code for ALL coffeelake models, does this work?), but this did not seem to make a difference.

What should I try next, flashing the BIOS differently, as you described? The Z170I's chip is a Winbond w25q128fv in a socket, so it can be removed for programming. Yes, I have a backup of my original BIOS, and I already saved my MAC and UUID.

edit: I checked wether I can do the pin mod on my board, but there's no Realtek audio chip on the Z170I, it has a "Supreme FX" audio. So I guess I want to flash the BIOS with a USB flashing device, and already ordered a CH341A USB programmer.

Thanks

Hello everyone,
I have an asus z170 deluxe motherboard. And, is it possible to run i3 9100f on that motherboard?

Hi, I need help,

It was doing fine until.......

ASUS Z270-dragon latest bios downloaded from official web site.

Thanks in advance.

@JayCar - Maybe just bad mos BIOS. Since you have programmer, there is no need for pinmod. Please flash Stock Asus BIOS using EZ Flash, then pull chip, dump it with programmer and send to me, I will make you BIOS
So I don't have to look back to find, when you reply with BIOS dump, please remind me what your old CPU is, and what your new CPU model and SSPEC is, as well as link to stock BIOS download page
For W25Q128FV use Colibri or ASProgrammer 1.41, both included in this package - http://s000.tinyupload.com/index.php?fil...213094641136166

Ohh, I see you don't have programmer yet Sorry! Please still link me to your current BIOS dump you first started editing, and tell me all I asked above again, as well as your current ME FW version in the BIOS onboard now (check with HWINFO64)

Hey folks, hope you're all well. New user here.

I've been looking through resources to guide me on how to mod my ASUS Maximus VIII Impact (Z170) so I can use it with an i7-9700f. As far as I can tell, these are the steps I need to take:
-Run revlaay's tool to generate a modded BIOS
-Flash the BIOS onto my motherboard (currently I'm a bit unsure about this, but I'll research how to do it further)
-Isolate/connect pins on the i7-9700f as necessary
-Install the processor and cross my fingers that the PC boots.

Is this everything that needs to be done or am I missing out some things here?

Additionally, has the ASUS Maximus VIII Impact been shown to work with Coffee Lake refresh CPUs before? I found mention of it being done on other ASUS boards when searching the forum, but not this one in particular. Its VRMs should be capable of it as far as I can tell.

Top work on these mods everyone, I'm really impressed by everything shown when looking through these threads.

EDIT: So, I've progressed a little further with this. The tool wasn't working with the latest BIOS for this motherboard (3801) so I reverted to an earlier version (2202) and it ran okay. However, there was an issue at the gop/vbios step as it couldn't find the vbios file. I continued with the process regardless and it all completed, giving me a modified BIOS file. Will this work since the gop/vbios step wasn't able to execute? Additionally, the file created is a .bin file, rather than .cap, how do I convert this in order to flash the BIOS on my motherboard via USB BIOS flashback?

@Lost_N_BIOS My USB SPI flasher arrived and I flashed the (same) modded BIOS with it. Now the CFL CPU immediately worked on my Asus Z170I. Now I have a running i5 8600k. I should have got this programmer right from the start, this would have saved lots of time.

Thanks for all your help and efforts! Now it is up to try how much OCing my i5 8600k can take. Edit: it runs 5.0GHz on 1.33vcore. Very happy with it!

Hey guys, I'm cross posting this from the other coffeelake mod thread since this one seems more active.

I've got a bit of a unique situation and I was wondering if I could get some help or advice.
I've got an Asus strix z270I and I'd like to mod it to work with a Xeon E-2288G I recently got my hands on.
The E-2288G seems to be identical to the i9-9900k other than the fact that it supports ECC memory and has a 100mhz higher base clock. From what I've read it seems that if I make the physical modifications to the CPU all that I need to do do the BIOS is add the correct microcode and update the ME firmware to a corporate version that will enable Xeon support.

I downloaded coffeetime 0.85a and used the advanced mode to modify the most recent BIOS for my board, v1205, I had to use advanced mode because it was the only way to add the 906ED microcode required by my processor since it is the R0 stepping. I received this warning message, which concerned me:

"Best way to use ASUS 200-series with 16-thread CPUs (even Xeons!) is manual porting bios from
compatible Z370 board. Automodifying is available for test purposes only.
Contact with CoffeeTime author to recieve ported bios variants for testing or wait this function
will be added."

I made the following changes to the stock BIOS in coffeetime:

s1151v1 BIOS updater for Coffee Lake CPUs v0.85a
[ 1 ] ME ver. - 11.8.60.3561 # Corporate
[ 2 ] VBIOS ver. - 1062
[ 3 ] GOP ver. - 9.0.1080
[ 4 ] PCIe x16 - Activated
[ 5 ] SKU hack - Activated
[ 6 ] Cores sync - Activated
[ 7 ] Init 16CPUs - Activated
[ 8 ] ACPI tables - Patched
[ 0 ] Microcodes - 906ED 506E3
[ H ] ME HAP-bit - ME ENABLED
[ T ] 12T blocker - Not found
[ N ] NVME fix - Installed
[ U ] FD Regions - Locks found!
[ M ] MAC-address - 888888888788
MCodes info - Found 2 microcode(s) in volume(s) 4, 5

I ordered a CH341A rom flasher and it should be here today. Can anyone tell me if the BIOS I made with the above modifications should work? Or do I need to get someone to back-port a z370 BIOS for me? Asus made a z370 version of my board that is almost completely identical so if anyone could help me with that I'd really appreciate it

The stock BIOS can be found here https://dlcdnets.asus.com/pub/ASUS/mb/LG...G-ASUS-1205.zip
And the Z370 version's downloads are here: https://www.asus.com/us/Motherboards/ROG.../HelpDesk_BIOS/

I'd really appreciate any help or advice anyone can give me, thanks! If there's anymore info I can provide please let me know.

@JayCar - great to hear it! Everyone really needs to have programmer before they get into this, or do pinmod, otherwise you can't flash in mod FD/ME properly

@emeraldx86 - Sounds like you need to ask @svarmod for test BIOS, from that message you received

@Rubl - What is your current ME FW version in the motherboard now? You really need flash programmer like CH341A + U Type Flat IC Extractor to do this properly, unless you are going to do pinmod and unlock the FD so you can flash FD/ME regions
What is your old CPU, I will make you mod BIOS with latest BIOS version.

Hello Guys

I hope I can find some help, I have a Asus Z270-A Prime MB and a i5 - 9400F CPU - it has a U0 stepping
I believe I already modded the BIOS, however whenever I install the 9th gen CPU the computer it does not boot, I have already connected the 2 pins on the CPU so that is taken care of,(I can upload a picture if needed), is there a way I can confirm if the BIOS is properly modded?

I believed is flashed properly since I had version 1009 and I was able to flash the version 1302 moded.

Please let me know what else is needed from me
I am currently running a i5-6500K and the system works fine with the i5-6500k
