I don't want to bring anyone's hopes up but it appears to be extremely related to the CPU clock + PCI card + the power line of the house going to your system + the quality of the Active PFC on your power supply unit. ( Did i just mention like 90% of the components, lol)

So what i did first was bought a voltage regulator that connects my rig + monitor only and as soon i fired it up it registered that my line was overvolting and the unit was correcting it. Next i lowered my CPU down to 4.6 ghz and left the voltage a little bit higher - same as for my 4.9 ghz stable clocks. Ram was set to 2133mhz Cl7 as with its specs. At these settings my machine was having problems cold booting before w/o the voltage regulator but now it seems to be running fine for the last 2 days w/o any cold booting issues. At the same time i noticed a bit higher values for the 3,3v line from ET6 with the voltage regulator which suggests that the Active PFC of my power supply was not coping properly regulating the voltage from the house line. Also i noticed that BCLK exactly at 100mhz was making things more stable than to let the mobo default it at 99.8mhz.

First i would suggest to try and lower your CPU speed down to like 4.4 ghz with memories at the right specs and slowly build it up multi by multi until it starts cold booting or if it is cold booting w/o any CPU overclocks try and get a voltage regulator - it is always better to have one anyways (~30$). Right now if i increase the CPU multiplier to 47 it has issues cold booting from the first time but it is stable once it boots to windows, up to 49 multi with 2133mhz ram. This is all still testing things but so far i had like 5 successful cold boots w/o any problems with 2133mhz ram (XMP - profile1).
I had cold boot the first time I turned it on (with PCI cards). And now, even without overclock sometimes it still boot twice when restarting or turning on. Most of the times it did not have any issues, but there is that 1 out of 5 of twice or three times booting-re-booting. And I intentionally still haven''t passed 3.9 Ghz overclocking.

I was saving my money to get one of this CyberPower 1500EAVRLCD
Still long way to go

Once while doing memtest my RAM was read wrong even if in the post and then OS read it right But anyway, I noticed a new problem: CPU-Z grayed out my RAMS??? For Instance I can't see my RAM in any of the 4 slots.. All grayed out.

If after reboot there is still this problem gonna reset CMOS tomorrow.
