PC isn't working after adding fourth RAM stick, three are fine, Asrock Z68 Pro3 Gen3

PC:
CPU - Intel - Core i5-2500K 3.3 GHz Quad-Core Processor
Motherboard - ASRock - Z68 Pro3 GEN3 ATX LGA1155 Motherboard
Memory - 4x Goodram DDR3 4GB 1333MHz CL9]
Video Card - Asus - GeForce GTX 970 4 GB STRIX Video Card
Power Supply - Thermaltake - Smart 630 W 80+
Operating System - Microsoft - Windows 7 Ultimate 64-bit




Problem:
I had 2 sticks of 4GB Goodram DDR3 1333MHz CL9, today I decided to buy another two. The problem is that PC isn't working when all 4 slots are populated. Two sticks in work, three sticks in work, but it isn't working with four sticks in. There are few different scenarios:
1. PC starts, shuts down after few seconds (nothing on screen, no sound) and this proces loops forever, untill I plug out power cable
2. PC starts, and nothing shows on screen, no sounds, and just stays in this limbo forever, holding power button shuts PC down
3. PC locks on POST
4. PC goes past POST and break on booting up windows (7 and 10 has the same result), something with checksum error and winload.exe, 0xc0000211 code, google says it's hardware problem
5. PC goes past POST, tries to boot, but during windows loading it restarts



What I tried:
Let's say that A are old sticks and B are new sticks. I tried multiple ways to check if it can be slot or sticks fault, but it all works fine, I tried:
0A0A
BA0A
BAA0
BA0B
BAB0

BABA and BAAB aren't working.
At some point I thought that maybe it has to do with my overclocked CPU, so I loaded my normal BIOS profile, but it didn't work. I loaded default setting, nothing. I also tried: normal OC settings - 46 CPU multiplier and raised up CPU voltage; normal OC settings and raised memory voltage; no CPU oc and raised memory voltage, nothing helps. I also removed MOBO battery for like 15 minutes, then I hold power button for some time and after this tried various BIOS settings - nothing. Slots are fine, sticks are fine, CPU OC isn't the issue. Any ideas? I'm fighting it for past several hours and I'm going crazy.

This is very odd, i had to re-read this a few times it seems like you've done your due diligence, have you tired running memtest with those configs that will post? if so, i may speculate maybe trying a different/newer cpu, since from what i gather the memory controller is located on the cpu in this chipset.

The motherboard or cpu probably degraded to the point where the furthest rams slots couldn't boot up. I had a similar problem with an old z68 with analog vrms which ran abit hot which probably contributed to failure in the furthest ram slot.
