"Now a question for connoisseurs ..." Who is lying? :)
Someone, you can write a full description of the memory strips installed in your Vostro, with timings, frequency and manufacturer.
Or even better, if possible - a full (or almost complete) report of hardware from Everest, for example.
I will be very grateful
