Z170 Extreme6 - debug code 99

Hi,

I'm using an 1-year old Z170 Extreme6 with a 6700K CPU. All is working fine with BIOS v1.20

Now I did a BIOS update to the newest v7.20 in order that I can use a 7700K on this board.

The update has been done properly.

After reboot, the bootscreen holds with debug code 99 and there is no keyboard command possible. I can reset and hit F2 to load the BIOS.. thats working.

After I went back to BIOS v1.20 all is fine. Win is booting and no probs at all.

Next thing I tried was to plug off all SATA drives, ext. USB drives, M.2 SSD, graphic card and 3 of 4 RAM moduls. Only the 6700K and one RAM is pluged. (RAM is G.Skill Ripjaws F4-3200C16Q-16GRKD / 4x4GB). After switching on, the BIOS is loading automatically without pressing F2. If I plug in at least one storage device e.g. the M.2 SSD .. it freezes with code 99

After this, I replaced the RAM module with another one. (G.Skill TridentZ F4-3400C16D-16GTZ / 2x8GB) - same state.. code 99.

Maybe you have a clue because I'm out of ideas.. the funny thing is that all is working properly with BIOS v1.20. But I have to update if I want to use the 7700K.

Here some screens:

Your links to the pictures show what I think is a registration screen in German for hardwareLUXX.

What method did you use to update the BIOS?

Code 99 is a problem related to PCIe devices, which is in your board's manual. I don't understand why you tried different memory.

Normally when POST fails and a code is displayed, you cannot get into the BIOS at all. That you have been able to get into the BIOS, before you removed your drives (I think) hints at a BIOS setting changed from its default value, compared to BIOS 1.20. I don't know if that is true or not. I'm going by the sequence of things you wrote in your post, which I assume is correct.

What M.2 SSD are you using? Is that the OS drive? Did you configure any BIOS settings for the M.2 SSD?

I know the CPU support list has BIOS 7.20 needed for an i7-7700K, but any of the 7.xx BIOS versions should work with it. Such as, 7.00 or the 7.10 Beta.

The M.2 slot shares resources with the SATA3_0 and SATA3_1 ports, in case you are trying to use both at the same time.

Why, it shouldn't be behaving that way in a Fractal Design case. Of all the cases.

After I pluged off all devices - except CPU and one RAM modul - I just tried another RAM modul to be sure that this curiosity is not caused by the RAMs. I'm using a Samsung SM951 with 512 GB as M.2 with an installed Win10 PRO system Like I said.. with BIOS v1.20 all is working and the OS is booting up. I just tested v2.xx. It causes the same like v7.20 .. freezing with code 99. I cannot do any keyboard actions until I do a hard reset. If I'm quick enough, I can press F2 to enter the BIOS. But dunno what I have to change there to get this working. SATA3_0 and SATA3_1 is not in use. Only CPU, 1 RAM and the SM951. When I remove the SM951, the system will activate the BIOS automatically. I supose that's okay because the board can't find any storage devices.. dunno.

Wait... wait...

Your first picture show the prompt to enter the BIOS, Press F2 or DEL, right? That is the normal prompt seen after updating the UEFI/BIOS. I've seen that screen 100 times.

The 99 code should mean nothing. If you are prompted to enter the UEFI/BIOS, POST completed successfully.

For some reason, your keyboard is not responding after any BIOS update after 1.20. Do you have another keyboard you can use?

What keyboard are you using? I assume it is connected to a USB 3.0 port? Is it wireless? Try putting the keyboard connection into another USB port, such as one at the top of the IO panel.

Yes, when the SM951 is removed, there is no boot device, so it takes you directly into the BIOS.

I can also press F11 to enter the boot menu. I can take a pick so the keyboard is working within this menu. When I press Enter after I have been choose a boot device - it freezes.
