ASUS Z170 Deluxe cold boot problem

[Smokey7]

This new build has an i7 6700k, Corsair Dominator Platinum 16Gb, Inno 3D GEForce GTX 980Ti and Samsung SM951 512Gb PCI-e x4 boot ssd amongst other things. It doesn't like cold boots.
The pc is in my workshop where I assembled it and when I built it a few weeks ago the weather was warmer. The build and bios/win 10 setup went without any problems at all. I updated the bios from 503 to 1101, again without any problems and used the pc for several days. Then the weather turned colder. The following day I booted the pc and found the count on the m/b display ran up to 41 and just hung for 3-4 seconds with the cpu led on the m/b lit and then there was a click and it rebooted. (41 isn't in the user manual!) It did this 4-5 times and then booted normally into Win 10. This performance repeated each day I turned on the pc. The temperature in the workshop is around 11 deg C. After 4 days of this I pointed my fan heater into the side of the case for a minute or so before cold booting and it likes that - it boots perfectly every time.
2 Questions
Anyone know which component is the likely culprit here?
Should ASUS be persuaded to provide a fan heater with each m/b?

It might be a safety feature built into the motherboard which senses temperature. This to minimize 'wear and tear' on solder joints and/or capacitors (swelling/shrinking). This might apply to other type of components, Im not certain.

I'm guessing it's the cpu socket "pins".

Might try re-seating the CPU?

Go to the BIOS and then Advanced/boot.
Look for the option for 'boot after AC power loss'. If it's set on FAST, change it to NORMAL, and see if that cures the problem.

If that fixes it, then update the BIOS, as 1101 has a serious bug which sums the v-core adaptive voltage incorrectly, resulting in a very high v-core voltage, as high as approximately 1.5V.

The latest BIOS is 1203

Some are saying they are getting error code 55 with 1203. They have to disable Xmp profile for it to work. Is it me or does it seem like the generations has a lot more bugs and takes a little longer to boot?

I read about the XMP issue with 1203. I prefer to set my DRAM speed and timings manually, so I haven't found the issue with the 1203 BIOS.

It does seem like there are a few bugs still remaining on this new platform. Then again, there is a lot new on Skylake. The transition to PCIe3 on the platform controller hub, and DMI3. The transition to DDR4, and Intel have removed the voltage regulation for the CPU, from the CPU and put it back onto the motherboard.

I guess it will take a few months more for this new platform to mature.

So if i set my memory manually you think the 1203 bios is worth the update from 0901?

For me, yes.
I had issues with 901 coming out of sleep mode. 1203 has cured that for me.

If 901 is working for you, then I would stay with 901, as don't like to try and fix something that isn't broken.
