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:
