hey everyone,
so I've been following this bios mod topic for sometime and finally decided to upgrade my 6700k to a 9900k on my M8HA but even after some reading i still have a few questions:
- I have seen it mentioned a few times that M8H does not need the insulation mod but shorting of SKTOCC pins are necessary which can be done on the MB side near the super I/O chip. does this apply to M8HA aswell?
- M8H uses a novutun NCT6793D super I/O chip does the M8HA use the same chip ( i have found a datasheet for NCT6793D which indicates pin #102 is the SKTOCC pin)
- from the info that I have gathered, on asus z170 boards to get 8c/16t working you will need a bios ver 2xxx , my board is currently running 2202 is this the optimal version?
- i have found on a Chinese forum(chiphell) a modded bios version 3801 for M8HA with 8c/16t support , is this possible? has anyone tested that version here?
- on the latest version of coffeetime (v 0.92 GUI) which of the patches do i need to apply to mod my bios i understand to add cpu support i have to add specific uCode but what do I have to choose under "patches" and "fixes", also do I have to disable ME( most of the guides use the older versions of coffeetime or AIO tool and they simply apply everything I`m not sure what to choose on v0.92 gui version and prefer to use the latest version of the tool hence why I`m asking).

sry if some questions are stupid or have obvious answer I`m trying to be as cautions as possible to not screw up.

See my screencap of CoffeeTime on previous page to know what patch yo need on an ASUS Z170 board.
Microcodes depends on which CPU you ant to mount.
Here is the 3 I have included:
906EC Coffee Lake S (Refresh)
506E3 Skylake
906E9 Kaby Lake


Yes, BIOS 2xxx are the only one to be able to works with 16 threads.
There are some experimental BIOS mods by svarmod (the author of CoffeeTime) that are able to boot on 3xxx BIOS with 16 threads, they reportedly works but no USB device are working before the OS loads, that means you need to plug a keyboard on the PS/2 port. I don't have found one for my mobo.

alright,
cpu is gonna arrive tomorrow in going to some testing and report back.

ok so an update:
Last two days i did the mod on two motherboards an Asus Z270-g and an Asus z170-M8HA.
on z270g i used a ported bios that i found on oveclockers.ru it was latest dsank rom ports updated with latest micro code. was pretty easy 9900k was working in no time. 4 sticks 8GB each gskill 3200mhz ddr4 worked nicely with XMP enabled.
on my m8ha i tried a beta 3801 version that dsank posted on a chinese forum , it booted usb was working however i could not boot from my nvme drive , my drive was recognized by the mb but even when i manually selected boot override it would simply return to bios setup screen ; because of that I used a 2202 mod that I myself created and its working fine with 9900k my two sticks of 8GB each gskill 3200mhz ram worked fine with xmp enabled.

some notes : my 9900k (m8ha) is running quite hot even at stock (~1.25 V core boosting to 4.5Ghz all cores) , my 360 AIO struggles to keep it cool at stock settings. i think i got a particularly sh*tty sample. though im not much of a pro in cfl OC scene might be able to make it run cooler.

Regarding boot up: Did you check CSM? What you report is the typical behaviour if UEFI tries to boot GPT from MBR drive or vice versa. Do you know whether the Z270-G mod was from an existing late Z270 BIOS or from a related Z370? I really would like to see progress on Asus UEFIs beyond 2202. (For M8R though, not M8H :-))

@PCGH_Torsten
yes csm was disabled , and my boot drive is a plextor m8peg 512GB nvme ssd which is GPT, drive is showing up in bios but it simply wouldn't boot.
I believe z270g was a port from z370g because it was showing up as z370g in bios you can find that bios in russian forum.
I cant read russian so i can`t dig too deep there but there might be some improvement to the latest mods for z170 boards there too (m8h,m8r etc.) . you can also try latest dsank mod from Chinese forum see if it works on your board.

one other thing that I just noticed in my modded 2202 bios the option for is AVX offset is not available i have to work on getting that back .

right now im trying to coffeemod hp prodsek 600g2 sff and im not having much progress there .

Contrary to popular believe, NVME can be MBR to. I am using that combination myself. :-)

Regarding prefab mods, m8r is hardly ever considered, so I only experimented with coffeetime modded 2202, but I plan to make a permanent upgrade this year and 38xx would be much apreciated for extended RAM compatibility and a couple of security fixes.

6 core cpu needs to modified ok, but i wonder 8 core cpu need to modified? ex. i7 9700f?

I have an Asus Rog Maximus IX Extreme. I want an Intel 6 core processor. How to do it? I don't know anything about it. Please help me.

Thank you for this guide.

For anyone interested in removing the mods getting rid of the lead pencil marks was harder than I thought. Actually had to use an eraser! Lol.

guys is there a bios port for M9C with support for 16T cpus (qqls to be exact )?

@svarmod
Could you please upload M9E BIOS once again?
Previous file you uploaded has been deleted or expired.
Sure it will be appreciated by more owners of Asus ROG Maximus IX Extreme.

I just got a i9-9900k during a sale, and now after reading like 30 pages of this thread, I'm not sure if it would work on my Asus Maximus IX Extreme. Did anyone else tested this combination?

I am using the M9E with an i9-9900K with 16t active. Everything works fine. The BIOS modified by Svarmod is here:
