@thanh25896 Great you're all recovered!

So, I checked ME of Z87 Extreme6 and Z97 Extreme6, and both have ME 9.1.xx with same VCN (Version control number), so you can backflash to this ME version in Z87 manually without issue using ME FW Update tool, so will be no issue if flashing it in without programmer does not work or you can't unlock FD etc.
I will help you do that once you flash BIOS, and check if ME reflashed or not, I will include the clean/backdated/settings transferred ME extracted from BIOS too, you'll use that with ME FW Update tool from following.
Intel System Tools Package V9.1, please download now if you don't have, don't use FTK package - https://mega.nz/#!uQV12IxD!KGAUutQZrdL7T...SugQhzGkt5K5EWU

Microcodes almost same too, except 306C3 19 instead of 24 in new one, ES microcodes are already same in both BIOS. So, either this microcode 19 is the key, or the slightly older ME version 9.1.2.1010
Here is BIOS with both the older ME and the ver 19 microcode. Your BIOS is difficult to modify in a way, so please be ready to recover from failed BIOS possibly, sorry. That maybe why BIOS from BIOS-mods failed too (Hopefully I made mod other way instead
If this fails I can mod other way instead, but this way looked better maybe, who knows though maybe other way is better? Change log included in file.

Put in non ES CPU for now, until we are done with this process.

Please flash twice (Flash, reboot to BIOS, flash again), unless asked if you want full or partial BIOS update, if asked you want full.
Once done with second reflash, please shut down, remove power supply plug from wall, short CMOS pins with jumper and leave there or remove battery, press and hold the power on button for 10-15 seconds
This is to ensure ME state is reset. Once done, remove jumper or put CMOS battery back, plug in power supply and boot to BIOS, load optimal defaults and the set SATA settings how you need, boot to windows and check ME version (unless you can see in BIOS, if so check there).
If ME version is 9.1.2.1010 great, we are done, you can test other ES CPU now. If ME version is not yet 9.1.2.1010, then do as noted below.

Go to Intel System Tools Package >> FWUpdate folder >> Local-Win << select that folder, then hold shift and right click, select open command prompt here.
Put ME file I included into the Local-Win folder, and then run the following command from the command prompt we opened at that folders location
FWUpdLcl.exe -f ME_Region.bin

If this method is used, you do not have to do any of the power drain stuff I mentioned, but you can if you want. Hit BIOS once done, load optimized, set SATA, load to windows, shut down and put in the ES CPU (Of course, once you've confirmed the ME updated to 9.1.2.1010)

Hi all! I'm glad to be here because i see people who know what they do.

Don't know if i can write my post here, but ill try.

My rig is Gigabyte B85 D3H rev 1.0/1.1 and i also have QDE4 B0

My bios is F15.

What can i do to CPU will work on my motherboard?

Can anyone add microcodes? How to downgrade bios if it is needed? How to enable K o/c mode? My motherboard can overclock 4670K, 4770K only with multiplier but here i can't.

You need ME and microcodes as discussed in this thread. To downgrade ME you need to either do pinmod to unlock your FD and then reflash with unlocked FD. If not pinmod, then you need flash programmer (Such as CH341A or EZP2010 or EZP2013), and a SOIC8 test clip cable.
Then you can flash any ME/BIOS combo you want with FPT.

On your K overclock issue, please explain more, is this for the B85-D3H you can't overclock, or what board? Confused because you said you can, but then can't? This also depends on ME/microcode versions too.

My mobo have option to o/c but this option don't work with QDE4 B0 because board don't see this CPU as "K".

This is my options when K is inserted. This options don't work with QDE4 and even don't show in menu like "K OC".

I don't have any knowledge over this flash programmers. I only can update from software.

Is QDE4 K-CPU? If not, then it may never matter if you can set K-OC or not anyway. But, I can force that "K OC" to always be visible for you if you want.
But first, please research and decide what ME and microcode you want in the BIOS, I will do it all at once for you. I assume, it may be same as we discussed here already.

ME you may need to purchase a flash programmer, I'm not sure, can't remember how Gigabyte flash tools react to ME back flashing. I will dig out my board like this tomorrow and see if you can wait, I'm sure I have one of these somewhere
I do not have K CPU though, only Pentium/Celeron for Z97

Yes. QDE4 is engineering version of 4770K.

I don't know which microcodes we must add to be fully functional with K OC options (like on the screen). Maybe it have to be identified as 4770K? I don't know. I have never changed that things.

http://www.cpu-world.com/sspec/QD/QDE4.html

Probably ES code, unless there was never ES code used for those during testing period and retail code always used. I can force the setting for you if you want to try that, I mean it will be there but you enabling or disabling may depend on certain ME or microcode.
QDE4 not listed as ES for 4770K (QE6S / QEH6) - http://www.cpu-world.com/CPUs/Core_i7/In...20i7-4770K.html

Where do you see it used and overclocked as a K CPU?

Here https://item.taobao.com/item.htm?spm=a23...ucket=14#detail

And all listed here https://s.taobao.com/search?q=4770+es&ty...utton&catId=100



you can translate it from google chrome automaticcly

There is no 4770K in that first link listing, only 4770S or 4770T shown in that listing image (#1-2 is 4770S/4700T). No QDE4 = 4770K in the search there either

Show me CPU-z of your CPU, main tab. I think maybe you purchased wrong # item there, or they sent you wrong one possibly?

https://gd2.alicdn.com/imgextra/i1/13322...png_400x400.jpg

NR5 is ES 4770/4790K 2.8Ghz QDE4

After translation:

Package 5: I7 4790K 2.8G Unlocked multiplier can be overclocked

4770K and 4790K have one ES

When i get back my CPU i will try to run CPU-Z (because motherboard don't identify it does not always start)

4770K and 4790K will not be same S-Spec, that seller is trying to trick/take advantage of buyers probably. I looked around in google, I see this is very confusing and not usual for these ES in 47xx series due to C0/B0 stepping and more varying ES than usual.
So maybe it is 4770K after-all, at least like 4770K

I know CPU-z doesn't identify correctly, I only want to see how it looks in CPUz-z. Do you want me to go ahead and force K-OC to always be visible for you in BIOS, no matter what CPU is installed (Even Celeron/Pentium it will still be there)
As far as it being unlocked fully, that's going to come down to certain Intel ME version, and certain microcode version. See if you can find either of those mentioned in posts on forums about this QDE4 and look on many of the for sale listings too, some might say which versions.
You could also ask the seller you purchased from, he should know what microcode and ME version work best for these CPU's

Ok. You can enable this K OC without B85 board?

Yes, I can enable settings without the board, but I do think I have one of these boards somewhere here. I mentioned having a board to check for you about how to backflash ME version, for that I will need to check for you unless you have a flash programmer (Hardware, like CH341A).
Settings I can do without having to get the board out at all, here is BIOS with K-OC and non-K OC always visible (Along with several other settings I enable for you too HT, ProcHOT, realtime CPU control in OS, CPU PLL selection).
Flash with Qflash or EFIFlash in DOS, please do not use @BIOS.

https://www.sendspace.com/file/7ajl7k

ME is already 9.0.30.1482, so you don't have to worry about backflash to older version, but if you want to update to 9.1 version we can do that via FW Update tool or BIOS mod
Either way should be OK, I was concerned before if you had to flash backwards to older but you're already using older ME.


Once you get info from research or asking sellers which microcode is best to use I can insert that or you too. But I think from this threads research already, version 19 was the good one to use, and it's in this BIOS already (And v 12 too).
Check with HWinfo or AIDA64 and see what CPU microcode gets loaded in windows, if 12 we can remove so 19 gets used instead (if above that, then win10 or OS update is overriding and you'll need to lookup how to stop that) ES 306C1/306C2 are also already there

Ok, thanks. I will send a post when CPU arrives

@Lost_N_BIOS

Hi. I have this CPU now.

CPUID is 000306C2 and Family 6 Model 60 Stepping 2

Revision FFFF0006

I cant overclock it multipliers.
