Z270 Supercarrier Issues on Reboot

I think this board is really a mistake.
I had a few pieces and they all had the same defects.
1) wifi card does not work (low sensitivity and does not connect)
2) some BIOS settings are not applied.
3) some of the usual BIOS settings are not exist
4) devices that you turn off in the BIOS (EFI) will not simply turn off.
5) The board behaves differently each time
6) After installing 4 graphics boards the board always dies.

Never in my life I have seen on my records damaged PINs on the socket. Here I got two boards with a damaged CPU socket.

I do not understand why they sell it at all.
I recommend that you stop wasting time, you have a faulty piece. If the BIOS reflash, reset to default and new settings does not work, return the motherboard.

There is no problem witch Windows!

sorry fot bothering you parsec, thats not my intention to offend you, not al all!!!

after days of testing i found these problems:

About the first problem:

Did you install the INF driver ver:10.1.1.38 and the Intel Management Engine driver ver:11.6.0.1126, from your board's download page? Both are essential for your board's basic operation, and should be the first drivers you install.

Disabling the CSM option should have no affect in fixing the restart problem. All that does is put the PC into UEFI booting mode, which won't work unless you installed Windows 10 in UEFI booting mode, and have the OS drive GPT partitioned. The CSM option may have reset to enabled automatically if you did not install Windows in UEFI booting mode. Did you check that CSM is still set to disabled? Every time you update the UEFI/BIOS, all the options are set to their defaults, and the default CSM setting is Enabled.

Your board has the Intel SATA III ports, and the add on ASMedia SATA ports. The Intel SATA ports are much better and should always be used for the OS/Windows drive. Booting from the ASMedia SATA ports will be slower and not as good as using the Intel SATA ports.

Did you have only the target OS drive installed in the PC when you installed Windows? If not, the Windows installer put the system/boot partition on a different drive. That can cause problems.

A Dr Debug code of 48 means a memory problem. Did you have your memory running at 3200 when that happened?

A Dr Debug code of 99 is a problem with a PCIe device.

Second problem:

The Aquantia LAN driver has been a problem since the AQC108 LAN chip began to be used with Windows 10. Windows 10 broke the Teaming feature of the Intel LAN chips, that has worked for many years. After almost two years, Intel has still not completely fixed the Teaming feature. That is just an example of problems Windows 10 can have with LAN drivers.

Since you are using Windows 10, I am sure Windows tried to install a Aquantia driver, but who knows which one. We have had the best results downloading this driver directly from the Aquantia website. Windows 10 has many different versions that are constantly changing, and Aquantia has been updating their drivers to be compatible with the Windows 10 changes and updates. Go to the page below to download the Aquantia AQC108 driver. Select AQC108 for the Part Number, and then complete selecting the Platform (Windows) and Language:

Windows 10 update has caused more problems when installing Windows then anything else I have ever seen. I do not connect the PC to the Internet when installing Windows 10, and do not connect it to the Internet until after I have installed all the drivers and software that is needed. I disable any automatic driver updates done by Windows.

You have a very sophisticated and complex mother board. It is too early to decide that the board has problems, you must install all the drivers and configure the UEFI options as needed before you can decide that the board is the cause of any problem.

If a hardware or driver problem prevents the PC from restarting, that does not mean the board is bad. You must install the two drivers I listed above. When Windows is being installed the PC restarts itself several times. If those restarts worked, why would another restart after installing a driver fail? Did you have the memory or CPU over clocked at that time?
