You have ME 11 correct (Verify in BIOS, F7 main section = ME Version), if yes then that is correct FPT

That's messed up, it says you need to disable write protection for the BIOS region and this is never disabled by Asus and it's not disabled in your BIOS currently either, so there should be no protection for the BIOS region to disable!

Let me flash with FPT on my end and figure this out, it's probably me and not you - I mean I am not super familiar with FPT because I always use a programmer myself, so I may be screwing up the command (Going by many posts on usage though, so it should be correct)
Give me a bit and let me figure it out over here with FPT or (USB Flashback). Sorry for the delay on this!

Try this while you wait on me, not sure if we tried this exact way yet? Make sure your in admin command prompt (you was previously, so same way)
fptw -bios -f 3401M22FixAll.rom

I will checkout flashing from BIOS first, then FPT - working on this right now.

I put your descriptor in stock BIOS and programmed it to my board, so aside from missing all my board details UUID, serial, LAN MAX etc my board would be in the same state yours is in now for this flashing process.
The only difference in your FD vs stock is ME region is set to no/no for read/write and stock is set to yes/no read/write. We aren't updating ME here anyway, so this is of no concern, but I noticed it so mentioning, unsure how your FD got set that way.

While you're having these issues, think of the future and all the BIOS mods you might want to do. Good starting point is picking up a CH341A flash programmer, that's all you need for Asus boards, and they cost $3-4
Get green or green/blue, don't get black gold - here's cheap one, will take 2-3 weeks or more to get to you, but you can purchase for 2-3x this price locally usually.

Will report back soon with my findings!

* Edit -

I couldn't get AFUDOS (Even ES Versions w/ GAN) or FPT to work, damn Asus!
You need a programmer from now on, it's so cheap anyway, then you can update more of the BIOS such as ME and microcodes etc later if you want.

I was able to get this EZ update / AI Suite to work for me http://dlcdnet.asus.com/pub/ASUS/misc/ut...10124-10015.zip

I unselected everything but EZ Update, let it reboot and it ran fine. If you can't get that one to work, maybe you may need .NET installed? That version works OK for me, if you can't run it, update windows or first install .NET and JAVA incase java is used?
I ran it on a testing system I use, not updated with recent windows updates, but I am not sure the latest update install date (Sometime in 2016 from my WIM image)
I do have JAVA 5 update 5 installed, and .NET 4.5 along with a bunch of C+ updates probably due either to .NET install or some of the 3D Mark Benchmarks, so maybe one of those makes it work OK?

Here, no matter what only use this new BIOS, edited once more back into a capsule and new .rom too. Throw away all other files, I noticed a settings error I missed previously.
When you get programmer you will write the .ROM file to the chip with programmer

Anyway no matter what I did, when I replaced the file using AI Suite before clicking update or after update and before flash, it always flashed the stock BIOS

You're going to have to get a CH341A flash programmer

Hello, both of you,

It's been a while, i was looking around internet to get HPET options in bios of ASUS Z170 ProGaming,
I just found this thread and im curious if you can do the same for me?

my bios version is unfortunatly not the same as Syntractrix so I can't use the .rar you uploaded.

my version is 3805

I would take any tips to restore my bios version to 3401 or anything if you can't unlock HPET on 3805 bios,
anyway I would like to thanks you

Regards;

Do you already have flash programmer? If not, order one now as mentioned above. I will make you BIOS tonight, and re-look into this flashing issue too.
BIOS region should be able to be flashed via AFU at very least

Still working on trying to figure this out, I haven't forgot!! 8-18
Going after this method now! https://www.insanelymac.com/forum/topic/...comment=1944166

Even AFU /recovery or /capsule methods do not work around this lock issue! AFU /GAN is a no go option here due to BIOS being too new to work with the older AFU ES versions (2.2, 2.3, 3.06) that support /GAN
If anyone reading this has modern AFU/AFUWIN that support /GAN and works with Aptio V based BIOS please PM me, thanks

@xetek & @Syntractrix - I figured it out! But, due to time is short for me tonight, I will have to write you out tutorial tomorrow! It is easy though, once you know what to do.
Flash right from windows using FPT, tested and confirmed working too!

@xetek & @Syntractrix - new mod BIOS 3805 will be here soon - Many settings unlocked, left CPU microcodes as they were in stock, if either of you guys want either of these BIOS with updated microcodes to test and compare let me know.
Coming as soon as I get it done, will edit this out when finished, but wanted to give you guys update here as I posted the guide. Fixing new BIOS for 3401 and 3805, so you may want to wait to flash 3401, or just reflash new once I'm done (More options available now!)

And here's how to fix this flashing issue. This FPT 368 error is due to "BIOS Lock" bit set in the BIOS itself, and this method can be applied to other BIOS HSFS register type locks such as SMI Lock, GPIO Lock, BIOS Interface Lock
[GUIDE] Grub Fix Intel FPT Error 368 - BIOS Lock Asus/Other Mod BIOS Flash

Good thing I showed how to on the IFR stuff, as soon as I posted that and updated to 3805 for testing, I found it's BIOS uses a different value to set the lock bit, so guide updated already.

Here is new MOD BIOS, both included here 3401 and 3805, no changes except settings revealed for many things, and then FIT table corrected post edit (no CPU microcode changes, hence two of three are out of date)

@Lost_N_BIOS Hi, can i use your modded 3805 with Kaby Lake (7700k)?

Hi @Flocc - yes, you can use that mod BIOS in post #19, both are past 3016 where compatibility for 7770K CPU was added. They are not modified other than what's described in this thread, meaning not updated microcodes or ME or anything like that.

Follow guide linked in #19 to flash if you do not have flash programmer. If you do have flash programmer you will need to edit in your board details (MAC, Serial, UUID, DTSKey etc), then confirm FIT table for CPU microcodes is still correct (If not, fix again)

Thanks @Lost_N_BIOS flashed BIOS, everything is working.
@xetek @Syntractrix what are your results/thoughts on HPET on/off.

Good to hear you got it all sorted out now @Flocc - in the future, you can make those variable changes in the BIOS modules before flashing on each new BIOS update via hex edit, switch enabled/disabled values for each lock, last four bytes (really only last byte in this instance).
That way you don't have to boot to grub each time, whichever way is easiest for you. If you do the BIOS edits, you'll have to do the grub unlock once more though to get the initial edited BIOS flashed in, then moving forward just edit each BIOS before flashing and away you go

If you need a good example of that let me know, I'll show you with some images.

Hello once again, and thanks for your amazing effort @Lost_N_BIOS .
I've came back to report good and bad news, lets start from the good ones first. Right, so I've successfully managed to flash the BIOS. And the bad ones are, is that my computer has been acting up lately, after overclocking my CPU the BCLK(?) is unstable . It keeps changing itself and messing with my clocks(they're constantly changing too) I cant get a stable clock ratio no matter what.

About HPET: Seems that ASUS has their own way of dealing with HPET already, even if it's enabled in BIOS your computer will not utilize it and use their own modified timer, but if you disable it the timers do get changed and I'm not exactly sure why.

Steps I've tried to fix this problem:

Disabling Intel SpeedStep
Disabling ASUS Multicore Enhancement
Disabling all of the C-states
Disabling EIST
Disabling any energy saving option
(I smell that turbo boost comes in place whenever the clocks keep changing)

I've also tried messing with the bunch of options that you revealed, albeit bunch of them are useless but some of them work.
Any help is appreciated





EDIT: Never mind, it's my motherboards fault.
By the way could you give me a list of the variable changes that you did while editing the BIOS? I'll tell you which are useless, and which of them to keep.

What variables are you asking about, or do you mean specifically BIOS settings? Variables I only edited the changes mentioned in post #19. As for BIOS settings, I made too many changes to note them all here, if you want to know compare in AMIBCP vs stock BIOS.
None I enabled are useless, maybe to you if you are not using them, but they all work and are all valid options to some people depending on what you are doing.

Did you get all the other stuff you mentioned figured out?

https://i.imgur.com/lDEdjKb.png
HPET OFF vs HPET ON (BIOS)
edit: did one more test (HPET OFF in BIOS + removed useplatformclock): interval:0.016, avg:236.18fps, max:22ms, load:98,30;99
edit2: HPET ON in BIOS + removed useplatformclock: 0.016us, 235.98fps, max ft: 20ms, load:98.05;99

I know nothing about HPET, so the images does not help me, nor does the info.
Do you need further changes in the BIOS, if yes I can attempt? As I mentioned before, some BIOS HPET is broken, even if disabling all three settings of it in BIOS.
In this BIOS you downloaded, I did not disable any, nor has anyone tested like you did, so I am not sure if this BIOS has broken HPET or only needs the other two hidden settings disabled.
If that is your goal, disabled HPET I can disable the hidden ones for you if you want?
