I'm glad everything is working.
If you're happy everything is stable then crack on with the overclocking.
Quit the patronising and get back on track with the OP's problem.
Loosen each of the 4 screws holding the H80 block onto the CPU by 1 turn and see what happens then.
Overtighening the CPU cooler can distort the motherboard and affect the RAM slots.
Nice catch.
done all that now
Considering overclocking the CPU today
Re-read the thread.
That's how to help the OP with their problem
you really are an irritant..like a flea!
