Asrock H170m Pro4 with1.80 BIOS

   Hello guys!

I have a few quick questions:

1. RAM OVERCLOCKING
Can it run my RAM at 2666Mhz? The Sport+ mode lowers the timings but it doesn't increase the Mhz.
Right now I'm running on Comfort mode with custom timings and voltage: 11-11-11-28@1.2v (2133MHz)
Anything below that and the PC won't boot. Are these results any food? Do you think I can improve anything?

2. CPU FAN SPEED
The CPU fan is not spinning at all if it's set below 50%.
At 10%, 20%, 30%, 40% the fan is not spinning at all. Is this normal?
Silent, Standard, etc. won't help.I use Custom right now:

3. CPU VOLTAGE
Can I undervolt my CPU with this motherboard? What does CPU Offset Voltage (mV) do? What value should I try?

Any suggestions are much appreciated!

	Is this the official AsRock support forum? Anyone?

	I don't believe you can run the memory faster than 2133MHz with H170. Regarding the cpu fan control, you're not alone and may be interested in this thread: http://forum.asrock.com/forum_posts.asp?TID=1392&title=h170mitx-dl-cpu-fan-control

	The best you can do on the H170 chipset is tighten your timings which improves RAM performance significantly. The bench results you posted are very good for 2133 frequency. From what I have seen it seems that is exactly what DDR4 OC does though I do not have supported RAM to test the feature on my own H170 board. Sadly my Corsair Vengeance kit does not provide the option.

	Thanks for the reply, guys! keeka, yes, we're all in the same boat with the CPU fan control problem. I'm still waiting for a solution to this hideous problem. Xaltar, can't you set your own RAM timings with the Corsair memory? If the AsRock Non-Z OC doesn't have a preset for your RAM modules, you should still be able to set your own timings. Anyone having any idea what the CPU Offset Voltage (mV) does and how it works? Can I undervolt my CPU on AsRock H170M Pro4?
