Z170 Gaming K6 and Fan-Tastic hangs in uefi

Of course! The more complaints seen about an issue makes it much more likely that the issue will be tested to see if it is true or not.

While I have had an occasional hang or freeze in the UEFI on my Z170 Extreme7+ board, I've rarely had it happen while using the new FAN-Tastic Tuning GUI interface. I use that to configure custom fan profiles, and it works great in general.

While the following is NOT an excuse for any freezing in the UEFI/BIOS, in my experience it seems to happen when I have my memory at its highest speed, 3200 for my Trident Z. Just wondering if you also have a higher speed memory in use.

I'm wondering if this is related to the VCCSA (System Agent) voltage, and the related (for memory) VCCIO voltage. VCCSA voltage is not a type of voltage that simply needs to be increased for stability, reducing it (from an XMP programmed value) can result in better stability. I've found my G.SKILL Trident Z 3200 memory has a very high value in the XMP profile (1.250V!), and I can reduce it to 1.160V at 3200 without issues... in Windows that is. There can be a difference between what is stable in Windows and what is stable while using the UEFI UI.

Another thing I think can cause the freezing in the UEFI/BIOS (again, NOT an excuse ) is if I am moving around in the UEFI UI very quickly. As I navigate around the UEFI, I try to pause a bit between mouse clicks, which seems to help.

A work around like this should not be necessary, but if it reduces any freezing, I'll trade that for the frustration of the freezing. Saving your UEFI settings in a profile immediately after configuring one or two is a good idea.

Tried to unplug all fan except cpu fan and cpu fan 2, same behaviour

I do not know what to do

An update

I switched to the second BIOS using the jumper, then I installed the latest BIOS (2.70). Using the second BIOS, I can enter the fantastic tuning and, even though the graphics is still corrupted (i see only the cpus and chassis fan 1&2, I cannot scoll down, but chassis fan 3&4 are selectable anyway using keyboard arrows and enter), I can modify the behaviour of any fan, even using the graph, without any hangs.

Notice that before the upgrade of the second bios to 2.70, the 1.20 was mounted, and the fantastic tuning worked well, even without graphic corruption.

Quite strange to me.
