A few errors per day seems much too frequent, unless you live at a high altitude.
Normal good DIMMs, at least when new, should not have errors more frequently than one error per many months.
Frequent errors may appear with memories that are not seated well in their sockets, or which are old, at least several years old.
Frequent errors may also be caused by more general computer problems, like a bad power supply unit.
Are DIMMs (a.k.a. UDIMM) still a thing?
I would think most servers and workstations would be RDIMM (Registered DIMM) by now and consumer stuff uses soldered down memory. Memory failing because it's old is definitely a thing, and very possible in this scenario, but I feel like I haven't seen errors due to physical insertion, that were not caught immediately by POST, in years.
But maybe it's just me. Happy to be lucky. :)
Curious to learn more here - why would altitude play a role here? And when you say high altitude - are we talking La Paz, Bolivia (~12k feet) or Denver, CO (~5k feet)?
Does this imply that the all plastic gamer PCs (that are more designed to be art projects than serious computers) are bad and that everyone should be using systems with solid steel cases to block radiation?
