Hi guys to start this off I posted here because I have seen more polite & helpful here people than on other website so cheers in advance for advice

windows 10 pro
i5 4690k / processor
msi z97 gaming 5 / mobo
g-skill 1600mhz sniper 2x4gig=8 / ram (displays & runs as 8g)
msi 750gtx / gpu
cooler master hyper d912 / cpu cooler

So I have checked both sticks aswell as A stock spare third ram stick in all slots
Both dimms 1&2 work, 3&4 seem to register ram is in the slot but refuses to install/boot
Checked that the max ram for windows 10 box is unchecked
Cleared cmos
The mobo's LED debug reads between number ending at 55 if it stays on long enough before loop
Checked the ram sticks both register as 4g sticks
 
Solution
Make absolutely certain that the CPU cooler is mounted evenly on the CPU. If not mounted evenly, the CPU may tilt a bit and lose contact with some pins/pads which can cause memory and other issues.

Try the DIMMs in slots 2 and 4? Then maybe slots 1 and 3?

BIOS up to date?
