The image does contain the ME version, but as you said, the eeprom does not talk with the PCH.
I tried a lot of commands to initialise the ME with no luck at all.
The most complete guide is this one:

And here there is the author of th guide that try to help in a similar situation.

I am in the same boat, no command works.

RT8065ZQW Replacement (ASUS) and Management Engine
Hello,
thank you for this forum and to share your experience.
It helped me a lot.
One of the things I learned is that a dead motherboard could be fixed by changing RT8065ZQW IC (or it's equivalent), depending on symptoms.
On a Z97 Pro, this replacement was enough to make the board boot and work, but I see N/A on ME version.
It is not a minor issue as ME and it's spi portion is responsible for other things, such as cpu microcodes.
It seems that the eeprom is not able to correctly communicate with PCH.
Already changed eeprom chip and I did... -
Asus Gryphon Z97 00 code and PU1 position
Hello,
I need to fix a z97 Gryphon with bootloop, exactly what happens here:
[url]https://www.badcaps.net/forum/troubleshooting-hardware-devices-and-electronics-theory/troubleshooting-desktop-motherboards-graphics-cards-and-pc-peripherals/90134-rog-maximus-vii-ranger-power-cycling-boot-loop[/url]
I would like to try the same solution but the Gryphon appears to be different from others.
I cannot find schematics and I fail to find PU1 position.
Maybe it uses a different IC for the same function and in a different position.
I am sure the problem is the same.... -
Re: Asrock Z77 Extreme4 dead?? Maybe not?
So I should look at a component close to the 1117 group (one on the image uploaded) or the culprit could be something far?
I need at least a specific place to test, the motherboard is too complex to make tests everywhere.
Thank you for your support....Leave a comment:

Re: Asrock Z77 Extreme4 dead?? Maybe not?
Don't know if you mean this, but I did it.
It appears that the 1117 is taking 4,88v and outputting 2,23v.
Could this be the problem?
Not enough volts in output?...Leave a comment:

Re: Asrock Z77 Extreme4 dead?? Maybe not?
Hi again,
I found a guy who "reverse engineered" an electrical scheme of an Asrock H97.
It uses a volt regulator 1117 in the exact position as mine, maybe the function is the same as well as the scheme.
Do you think this can be helpful to troubleshoot my motherboard?
Find it attached, it is at section (13) 3.3 VSB Supply (PCH/LAN)
And here:
[url]http://www.edaboard.com/thread161775.html[/url]
it says that the 1117 is used often to lower 5V standby...Last edited by Uazzamerican; 02-05-2017, 03:43 AM.Leave a comment:

Re: Asrock Z77 Extreme4 dead?? Maybe not?
Ok I measured the pin3 also.
I get "1" , so no reading, whatever scale I use.
Just a note, I have a reading of around 300 on pin1.
I really don't know how to move, I was hoping to go to the technician saying him to change this or that smd/capacitor, because no one here will ever try to fix this motherboard without asking more than the price of the motherboard herself....Last edited by Uazzamerican; 02-02-2017, 07:08 AM.Leave a comment:

Re: Asrock Z77 Extreme4 dead?? Maybe not?
Ok I think I did the measurement you required.
Putting the red probe on the tab and the black probe on one end (or the other) of the 000 resistor, I obtain 475ohm.
The same if I invert the probes.
Did I made a correct resistance measurement?
That said, the trace clearly goes from the tab to the capacitor and from the capacitor to the resistor as far as I can see (you can see on the image as well)....Last edited by Uazzamerican; 02-01-2017, 02:14 PM.Leave a comment:

Re: Asrock Z77 Extreme4 dead?? Maybe not?
Thank you for the help.
Actually I see onboard only two 1117 regulators (both visible on the image uploaded).
How comes the readings are ok if they are different from one regulator to another?
Second, how can I check the resistance on the 000 smd? (Sorry... Treat me like a child please...)Leave a comment:

Ciao, spero che il messaggio ti raggiunga. Anche io ho un problema col regolatore 1117 ed un condensatore su una Asrock. La stessa identica disposizione.
Praticamente identico al tuo, incandescenti entrambi in stand by, nessuna accensione.
Purtroppo non ho la tua competenza.
Tu come hai risolto? Io sono di Milano... -

Thanks, I think...
What is your opinion on the specific issue anyway?
I see that someone else has encountered the same issue:

Re: Asrock Z77 Extreme4 dead?? Maybe not?
Thank you Momaka for your support!
I have done the tests you suggest me, I tested both the 1117 regulators, to have a control.
On the (maybe) broken one I have no readings regardless of the scale I use on the multimeter:
2black>3red = "1" on the screen
3black>2red = "1" on the screen
On the functional one, with 2000 scale I have:
2black>3red = 1263ohm
3black>2red = 1247ohmLeave a comment:

Re: Asrock Z77 Extreme4 dead?? Maybe not?
Second attempt:
I set the "2000" scale and now I get proper readings.
It says 474 ohm on the 1117 tab.
If measure the other 1117 (the one on the top left of the image) it says 498 ohm.
I wish I know what that means.Last edited by Uazzamerican; 01-31-2017, 03:27 AM.Leave a comment:

Re: Asrock Z77 Extreme4 dead?? Maybe not?
1) 2) and 3) are the little pin on the 1117, from left to right.
I followed entirely the guide on this forum on measuring voltages on 1117.
I have a cheap digital multimeter, I hope it will be enough.
Putting the black probe on a ground washer space (or on the I/O connection metal case) and the red probe on pin 2 or the fat tab, I obtain nothing but "1".
The same for another 1117 on the motherboard.
Maybe I am not using a proper "ground" point??
If I put the black...Last edited by Uazzamerican; 01-31-2017, 02:13 AM.Leave a comment:

Re: Asrock Z77 Extreme4 dead?? Maybe not?
Hi!
I just tested (I think...) the voltage regulator, following the guide on this forum.
I used as ground, a space for motherboard screw (plated).
Here the data:
First line: 1117
Second: 21601k
1) 1,42
2) 2,23
3) 4,88
Now, from the guide the second reading value should be the first plus 1.25v
It is not, so the regulator is bad and should be changed. Right?
What you suggest me to test?Last edited by Uazzamerican; 01-29-2017, 08:33 AM.Leave a comment:

Re: Asrock Z77 Extreme4 dead?? Maybe not?
Ok
I verified the 1117 and it is hot indeed.
I cannot tell if the heat it produces spreads to the caps OR they spread heat as well themselves.
Anyway, should I change the 1117 as well?
As far as I can tell, it is an adjustable regulator because I don't see any suffix after the number 1117. Am I right?
Should I change (or look for)anything else?
I need the more info I can get before I go to the technician (he doesn't care...).
Thank you !!Leave a comment:

Re: Asrock Z77 Extreme4 dead?? Maybe not?
The only thing I know is that the bigger gold cap is hot as hell, just plugging the power cord (the system won' t turn on anyway, no fan, no beeps, nothing).
It is possible that the 1117 thing is also hot, I should verify, but I cannot see damages on it.
But what does that means? What should I change?...Last edited by Uazzamerican; 01-26-2017, 01:18 AM.Leave a comment:

Re: Asrock Z77 Extreme4 dead?? Maybe not?
Well I am no technician, but it is something encouraging.
I cannot find anything wrong in the motherboard (and I was able to spot a fried diode on the Maximus), but I must say also that the CAP seems to be perfect, except for the crazy temperature it reaches just plugging the cord.
I will try to replace it, maybe both just to be sure.
What type of caps should I search for? I would like to use the same type for both.
Thank you for your help.
Any other will be...Last edited by Uazzamerican; 01-25-2017, 12:23 PM.Leave a comment:

Asrock Z77 Extreme4 dead?? Maybe not?
Hi all...
After attempting (with no success) to repair a Maximus IV Extreme, I am now trying to fix an apparently broken Asrock z77 Extreme4.
The board seems really perfect, nothing to report.
Except that it is dead.
No beeps, no lights, no fan. Only thing it's on is the led on keyboard.
After a full inspection I found that a gold cap near the internal power button gets extremely hot when I power on the PSU.
Maybe the problem is the cap? Se the attachment.
It says "LF 560 j 25C" on it.
I don't see damages on...Last edited by Uazzamerican; 01-25-2017, 09:05 AM. -
