Hey man, I’m having a lot of trouble flashing a new unsupported bios (it’s a .bin file) on to my z270i

I would appreciate your help so much.

@jordanpchome
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.

Hi everyone,

My MB: Asus IMPACT VIII (micro-ATX i guess)
Bios: 3xxx
My 6700k died. I guess the Delid i did 1y ago killed it today because of TM not well applied. My fault...

In the past i spoke already with @Lost_N_BIOS and @svarmod . Really appreciated all the time you guys spend sending pm's and helping people here.
I did some homework in the meanwhile but didnt move forward.
I got a CH341A programmer and i took my BIOS chip out.


Since i dont have PC, im using the laptop from the office. I'm planning to get a 9900k or 9900kf today. I got good deals from people changing to ryzen 5xxx series.
I've downloaded the coffeelake 0.92 tool and based on my 9900k or kf choice i know from the .ru table that i need a 2xxx bios.

1. I also believe @svarmod already uploaded a bios for Impact VIII but i dont find it and the one i found the link was broken.
2. I think i have my Mac address on the MB box! Otherwise what can i do about since i dont have the MAc address due to no system at the moment ?


3. I've open the 0.92 tool and used the cap bios 2202 file from asus. I see a lot of reds. PCIEx16, SKU hack, sync cores. The only hack green is: init 8 and me recovery

So, what do i need to do here?
I guess:
a. patch pciex16
b. patch sku hack
c. patch sync cores
d. patch acpi tables
e. fd locks i guess its only needed if i want to flash thru ez flash usb pen correct? I could do that way instead of ch341a programer? And what about SPD write protection on the extra?
f. i dont need nvme and this board doesnt even have that
g. pcie 1440 i dont know what this is and i dont think i need it


ME shows enabled and 11.0.0.1168. Should i change to 11.7.0.1229 ?
vbios +gop i dont know what this is. Default here is 1033 orom and 9.0.1042 orom
MAC1 and SN are empty but i will try to get that from box. UUID is also empty.

Then i guess i need to save image and flash it correct?
Anything else?
BTW, can i then flash thru EZ ?

I think the bug is windows related.
I have an older win10 version and run with admin. The 0.92 version did the vbios patch to 1062 properly and 9.0.1107 version

hi

why can't insert new serial number ?

thanks

@Vapochilled: I've never seen a pattern when PCI-E mod is needed, but I also now of no disadvantages, so I would add it to the list. Likewise NVME – you cann plug m.2 into the PEG using an adapter or HHHL-SSDs directly. While this might not seem attractive as long as you are runnning a decent GPU, it might be handy latter when the ITX board has been passed on from the main system to an office or multimedia rig, where IGP suffices.

FD unlock: I consider it a must on flashback enabled boards as it will allow you to work without ch314 hassle in the future. Unless you are one of the lucky few who have a an unlocked@stock Asus, however, you have to use ch314 once to flash the unlock itself.

Regarding MAC I would just use flashback to put 2202 on to the board as regular update, than dump that image using ch314. This way you start your modding with a preindividualized 2202 including all personal parameters.

@Vapochilled
The Asus M8I board does support NVMe via a U.2 connector that is on the board. There are U.2 to m.2 adapters available on e.g. Ali. That will allow you to use m.2 drivers, or alternatively you could look at U.2 NVMe SSDs - e.g. Intel 750 SSD, or some of the newer ones (these tend to be data centre oriented and pricy however).

Correct, file must be renamed and iirc the name was board specific on Maximus VIII. So it will probably something like "m8i.cap", just check the manual. Flashback will than be able to flash the !unlocked! parts without need for a running/already compatible CPU. But Flashback cannot write to locked UEFI segments, so for 1st write to FD you will very likely need ch341a. And also in your special case you need it for dumping - once the system is up and running (and unlocked) you can dump via software and flashback is just the more comfortable and safe option as you will not have to circumvent integrity checks or worry about instabilities as with software flashers.

Microcodes: It has been 1.5 years since i worked with Coffee Time, but iirc you can select the microcodes you want in a list.

@svarmod, can you elaborate on what the asus 12t blockers patch does? Is it required for z170 2xxx bioses to support >8t (on top of init 8+ cpus)? thanks

just picked up an open box 9900k. works on 3xxx with ht disabled as expected, but the additional 12t blocker patch doesn't help. Any ideas on ht with 3xxx? Or maybe porting over some modules from 3xxx to 2xxx for better ram support? I'm running 4 dimms, and with 2xxx can't seem to post higher than 2133.

Still experimenting, but preliminary testing seems to suggest this 9900k is a better clocker than the two 9700ks I've tried. Still finding c6+ states to require significantly more voltage, but limiting to c3, I'm able to run 5ghz @ 0.9 ia ac/dc loadline, for ~1.26v non-avx / ~1.32v avx. I suspect the STIM may be poorly soldered on this chip though. With the exact same settings, I was seeing peak voltages in the low 70s with throttlestop's ts bench. This chip has 2 cores spike to the upper 80s. A heavier avx2 load like p95 immediately sends these cores to 100c => thermal throttle. Probably why it was returned. Not that big a deal since I plan to run 120/150 power limits anyway which should keep those cores just short of throttling

@ziddey
Thx for the info about problems in running 4 dimms at higher speeds on the 2xxx bios.
I am curious as to what is so special about the 2xxx bios in that it can run 16T fine while the 3xxx bioses cannot and whether the module / modules that make this happen can be transplanted from the older bios to the new 3xxx builds.

@mtothaj just remembered one of your old posts: [GUIDE] Coffee Lake CPUs on Skylake and Kaby Lake motherboards (8)

did you ever explore further? maybe I should research if there's an analogous z370 board to mine and go that route

@ziddey
I sold the Maximus 8 Impact a while back, currently have a Maximus 8 Formula board.
At least from my experience and reading , cross flashing on Asus boards is a pretty risky process due to possibility of TPU being bricked during the update.
In any case, crossflashing is not really feasible on Z170 since the differences vs Z370 are just too great. On Z270 on the other hand it is a possibility, on condition that you have a Z270 board where there is a Z370 equivalent - in that case it will generally work fine, minus a few possible hiccups e.g. aura rgb not working.
So generally - Z170 gives possibility of running 16T when using an old bios version. Z270 gives such a possibility via cross flashing a Z370 bios region - provided an equivalent Z370 board is available.
My preference would be that a method is devised where you can use the latest bios build and Coffeetime - just as you can do now for e.g. 8600k or 9700k. This just seems to be the most stable / guaranteed way of modding - you sacrifice nothing and gain performance on par with a standard Z370 / 390 board (minus possible power saving states etc.). The bios region cross flash method or running an old bios build seem like an inferior option in comparison but then it seems that at the moment until someone works out what the problem is these are the only two options available to run 16T at present on Z170 / Z270.
