Hi, I got a strange problem. Please help

my config:
i7 4970k + CM212EVO
Asus Gryphon Z97 Armor
MSI GTX 970
RAM: 4x4GB Kingston HyperX FURY DDR3 1600 Black
PSU: Corsair CS650M

This was a working config without any problems from day one, running for a year or so. Yesterday I replaced the stock cooler with a new one (CM212evo) and after reinserting everything i just won't boot. DRAM LED is solid red, MEMOK! doesn't do anything. I tried all kind of combinations, removing the newly added cooler, reseating etc. The strange thing is it will boot with just 1 mem stick (works with each individually). Then after I messed with CMOS reset it wouldn't boot with any. Then after reseating everything it booted with just 1 stick again and I'm writing this from it.
I can't use my other 3 sticks, everything else seems to work normally.
Help?
