Hi, just received a Z170 Gaming K6 with preinstalled 1.20 Bios. 6 total fans connected: one 4-pin CPU fan in CPU fan slot 01, one 3-pin fan in CPU fan slot 02, and 4 3-pin fans in the chassis fan sockets. If I enter the bios, and if I enter in Fan-Tastic Tuning, I can see the graph on the right and all the fan on the left, and I can do whatever I want, and the settings are applied correctly. After that, I updated to 2.00 BIOS, but when I try to enter the Fan-Tastic Tuning from advanced mode, the Uefi hangs. Tried 1.80 Bios, same situation. Reflashed 1.20 bios, and everything is ok again  Cleared cmos, updated again to 2.00 and again uefi hangs in this situation. For now, I use the preset Silence for each fan, but I cannot enter in fan-tastic and modify the graph because it freezes. So it seems to be a BIOS related problem. What can I do? |

Unfortunately this happens to me too. It also happens when you're just navigating through the settings. I reported this a few weeks ago, but even the newest BIOS version doesn't seem to fix it. I only hope that ASRock will keep an eye on this matter. |

This same situation happens to me. My UEFI hangs, update to v.2.00 don't fix this problem. This is kinda JOKE!!! |

I suspect the issue is being investigated. It seems not to occur on all configurations. If all of you experiencing this issue could share your full system specs that will likely prove helpful to Tech Support. It is also worth noting that BIOS freezing issues are not exclusive to ASRock products which leads me to believe that it may be a gremlin with Skylake itself. Regardless of where the problem stems from I am sure ASRock is doing everything they can to resolve these issues. -------------

Sure. These are my specs: - Core i5 6600K (OC to 4.4GHz @ 1.28 V, same problem with stock) - Corsair CMK16GX4M2B3200C16 (at 3200 xmp, same problem with stock) - Asus R9 390 Strix - Corsair RM750i - Samsung 850 Evo 500GB - Cryorig H5 - Cooler Master 690III - 2x Corsair Air Series AF-140 LED - Corsair Air Series AF-120 LED I do not have any other bios freezes, it happens only when I click on Fan-tastic |

Exactly same problem. And not only this one. Strange start up behaviour after power loss, unstable PC with bios 2.10 and more. ------------- Intel 6700K@4,6GHz (+70mV), Z170 Gaming K6+, 16GB Corsair 3200MHz 2T |

I have in bios set stay off after powerloss. But if my pc is off and power is lost, then after power is back online pc starts to boot. But after few seconds it shutdown itself, after moment startup again, but stay in frozen mode with black screen and power led shining. I have to plug out and plug in power cord, After this is pc able properly start and all next starts are OK till next power loss. ------------- Intel 6700K@4,6GHz (+70mV), Z170 Gaming K6+, 16GB Corsair 3200MHz 2T |

Bump? Should I contact the Tech Support to inform them about the issue? |

Hi, I've had the hang issue on the Extreme7+. But, many times, it unhangs after 30-45 sec and it becomes responsive again.

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. http://event.asrock.com/tsd.asp" rel="nofollow - http://event.asrock.com/tsd.asp ------------- http://valid.x86.fr/48rujh" rel="nofollow">

Updated today to BIOS 2.70, same issue: as soon as I click on "Fan-tastic Tuning", the UEFI hangs. I can only use the preset for the speed of my fans. |

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. ------------- http://valid.x86.fr/48rujh" rel="nofollow">

As I updated, I noticed that the VCCSA was indeed 1.250 with my Corsair CMK16GX4M2B3200C16, and prime95 gave me errors. So I put the VCCSA at 1.15V as it was in bios 2.00 before the upgrade, and now everything is fine in prime 95. But the fantastic tunig keep freezing again. Even with RAM at stock profile (not xmp at 3200) it hangs. Even if I move very slowly inside the UEFI interface. Maybe I can try to unplug one fan at the time and see if doesn't freeze, but the fact that with 1.20 bios the fantastic tuning worked great with the same hardware and fan configuration, it makes me think that this is a uefi related problem. The fantastic is an awesome utility, and using it only with the preset is a bit bad for me. |

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. |
