This is not what I'm reporting...and I do know that much about PCs after 25 years.
If you can please take a look at the initial post and the pic, you will see that, in the left screen, speccy reports as installed RAM the RAM available (to the OS), and does not report spd, whereas in the right one, it reports the correct installed and available RAM + the spd.
In that pic you see two speccy instances for the same PC...and that is erroneous RAM reporting!!! It should have been the same at all times.
By the way CPU-Z reports the RAM and the spd correctly at all times, i.e. there is nothing wrong with the laptop, that's why I created this post, to report a possible speccy bug.
Thank you. Dimi
