Hey guys

I have installed a new cpu cooler (212 spectrum v3) and new thermal paste
after that the ram doesn't work as well (i have 2 sticks of 16gb each)
and my pc reco only 16gb , when i put the second stick my pc keeps restart it self back and forth

any idea ?

I have tried a1+b1 and a2+b2

This is gonna sound weird but, try a1+a2 and b1+b2.
I know it won't run well, but if it boots that'll indicate a faulty memory controller.
