Hi adriants
Which of the Corsair coolers are you using? Anything less than H105 and you can have problems.
Regarding a 4pin cable, You can very often split apart an 8pin plug and tie the other half back. It will be essential if you want to OC and helps with stability. If not, you will have to buy one which are easily available.
Your DIMMs, neither the Corsair or G.Skill, are listed on the ASUS QVL, so they may or may not work.
Try with just one DIMM in first slot to test and try switching around. You may have to test using Memtest86+ to eliminate that possibility.
If these things once checked, do not find the fault, You will have to remove the MB and benchtest your system outside your case, incase your MB standoffs are shorting. Should it come to that, I can give you the fault finding procedure. One step at a time and adding one component at a time.
At each startup, make sure to observe your Qcode to see if any changes and report them.
