You mentioned 24 GB of RAM.
This is an unusual number - I've never heard of anything other than 4, 8, 16, 32, 64 and for very lucky people, 128.
Is it possible that you should have 32 and one bank of 4 has failed?
Such a failure would slow everything down in the manner of a flat tire on a car. The other three might be perfect but...
That is addressed in the opening post.
If theres some special procedure for it, that possibly the OP neglected to follow, maybe you could dig deeper into that !
