Hello! I've got a deal on a 9900ks and was wondering If my ASUS z170-a has The capability to run it? I am specially worried about higher tdp of The ks model. Or am I just better off selling my mobo and get a new one. If The vrm is sufficient and all is otherwise green, i'm gonna short the skt_occ pin to ground and do the BIOS mods. And is it absolutely necessary to isolate the couple of pins on The cpu?

Giving coffeetime 0.92 a go for an asus z170 pro gaming/aura + 9700k without nvme. Are there any downsides to throwing the kitchen sink at it? Don't need init 8+ cpus, acpi tables, nvme fix, or asus 12t blockers right now, but they'd be useful if I ever want to swap in an 8700k/9900k. Or would patching/not patching acpi tables be the cause for low vids / unstable with >c3 without excessive voltage set?

Programming a spare chip now to test

edit: Looks like behavior is the same. On default settings, everything seems stable, but the worst case vid table is too aggressive: load voltages around 1.45v. Setting best case (0.01 ia loadline), llc3 (slight full load droop) with a +0.075v offset, and limiting c-states to c3, and we're back in business. Adaptive turbo vcore is still broken. Could this (and inability to run deeper c-states without excessive voltage) be affected by the acpi patch?

I haven't tested, but to run full c-states requires far more offset.

I tested fixed voltage a while back and found 4.7ghz to need ~1.24v actual. I believe this was done with c-states disabled. With the current offset and llc3, I'm seeing ~1.27v with a heavy load and a max vid of 1.34v (lighter loads obviously closer to 1.32v). If anything, llc can probably come down another notch to get heavy load voltages down further

edit2: I read up on the acpi patch. Doesn't look like it

edit3: Decided to try running it close to spec: llc1 (lowest), 1.6mohm ia ac/dc loadline, auto voltages. Still saw idle/transition whea bsods. Then realized this psu is old and cheap and probably can't handle c6/c7. Disabled c7/c8, and reported vcore seems to bottom out the same at c6 as at c3. Another bsod and c6 will go off as well.

CoffeeTime 0.92
--- Download ---
----- Mirror -----

- Improved compatibility with CFL 1440
- Added replacement system of all existed VBIOS/GOP modules
- Couple of extra mods:

• Removing SPD Write Protection
• Unlocking maximum RAM 128Gb
• Replacing cores/threads count display type in BIOS from hexadecimal to decimal

This case described in CoffeeTime changelog in readme.txt - AMI table has custom name changed by vendor.
All you need is create "data/custom/aminames.txt" and write a string with table name from info window: "GBTUACPI".
Then try patch ACPI again - it should be ok.

Try this bios for M9E - it's most complete modbios variant for 9700k at the moment (use SPI programmer).
But I think your problem not linked with coffee mod. Did you tried plug in GPU right into board w/o riser? Same troubles?

I'm using this variant of svarmod

Hi @svarmod , i want use i3 8100 with mb asrock z270 extreme4 , so i mod bios by CoffeeTime to create file bios then i copy file bios in usb and flash by instant flash of asrock but it notice instant flash secure so i use UBU to remove instant protect flash . I flash bios done but when i place i3 8100 in main ,it not working .Can you help me solution this problem . Tks you so much

@hongthaihp95
First thing you have to do is to unlock all regions to read/write in spi on your mainboard. Do backup of spi via programmer, unlock regions of this backup in CoffeTime and flash that image with programmer. Since that moment you can flash any image via FPT. Of course remember to flash images with unlocked regions only.

hi all, can someone with more experience guide me to not to brick the motherboarad?

I have an asus z170i pro gamng itx board with an i5-7600k. / 3085 bios

and want to upgrade with a i5-9600k

so the steps are

1. use coffetime to make bios
downgrade to 3610 bios and SRELU stepping
2. extract bios chip from board
3. save original bios file
4. put modified bios on chip
5 hardware modification on cpu

i have the Ch341a programmer and chip extractor

and thats all?

thanks in advance

BIOS internal flashing tools can't redlash image fully.
You need to use SPI programmer to made it.
Also, check your current ME version and CPU 8100 revision.

@kixezi
You have other PC to flash chip, right?
1) Backup current bios, using SPI programmer.
2) Modify latest bios from site with CoffeeTime.
3) Transfer personal data from backup image to modbios (MAC, UUID, SN).
4) Flash modbios using SPI programmer.
5) Make pinmod for CPU
6) Profit.
