The CPU is Land Grid Array. (Very sharp metallic spring bites
into gold plated land.) Normally, this is reproducible any time
the CPU is removed and replaced. And the arm that applies pressure
is locked down. The pin sharp point, always goes precisely back
into the bite mark.

Is the CPU arm locked down right now ? You could have some pretty substantial
cooler on it, so sometimes inspection is difficult.

Land Grid Array works up to (so far), around 9000 contacts,
but I have no idea how the "pressing-force" is equally distributed
so all the lands have good spring contact. The hobby CPUs don't
have nearly the same LGA counts.

There have been CPUs that burned in sockets, because of poor contact.
There were two brands of sockets, Lotes (good) and Foxconn.
The Foxconn issue was not repeated on the next generation.

The generation I use here (AM4) is PGA or pin grid array. And the
socket is ZIF (Zero Insertion Force). Moving the lever on those,
provides side force making the "contacts touch the pins". When you
remove a heatsink on those, you can pull the CPU right out of the
("locked") PGA socket :-) That does not hurt anything. There have been
cases where PGA pins were crushed. A metallic ball point pen refill, could
be used to (carefully) bend a PGA pin upright again. And that kind of
surgery is not always successful (but, ya gotta try). When you make a mistake
and that happens, you can usually tell the patient is not going to survive
the attempt to straighten a pin.

DIMM socket pins, almost never foul...

It would take a determined individual, bent on destruction,
to do actual damage to a DIMM socket. The pins are very very stiff.
It takes mallet-level attempts to damage it, to mess it up. I
highly doubt there is any reason whatsoever, to be "cleaning"
the DIMM socket.

Similarly, the "pink eraser crowd", I'm not with them. Gold on
electronics, can be applied 10u or 50u. The latter thickness
is used on telecomm contacts. The former number is used
on computer industry equipment. Applying abrasives to
10u gold is a "mistake", doing more damage than good. There
are already pinholes in the finish, due to the thinness of
the plating.

There is so much wiping-force on DIMM insertion, there can't possibly
be a contact problem. Only a corrosive liquid (Kings Reagent would do),
could do a job on the contacts.

I just don't see a reason to be fooling around with the socket.
I'd rather reseat the CPU, then bash on the RAM (the RAM interface
is on the CPU package). There's no question something bad is going on,
 but it probably isn't the fault of the DIMM contact there. If you actually
managed to bend a DIMM contact (!), the DIMM would no longer seat and lock.

I've visually inspected DIMM sockets with a magnifier, and have
not had a reason to be suspicious of what I'm seeing.
