I’m having this strange behavior where my system reports 62.3GB of RAM instead of 64GB. Does anyone have any idea why this is?
In the BIOS it says the usual 64GB.
Simply different systems of measurement.
Try sudo inxi --admin --verbosity=8
OK, that helped. Now I see 64GB total. Thanks.
Memory: System RAM: total: 64 GiB available: 62.38 GiB used: 6.92 GiB (11.1%)
Very strange. I’m pretty sure the system used to show 64GB everywhere. Now I see 62.3GB everywhere (KDE System monitor, btop, inxi, etc.). Was there a change in how RAM is reported with one of the kernels?
Did you notice the sum after the 64 does not work?
There isnt supposed to be a sum.
These are all different numbers.
The total installed RAM
The amount of RAM actually available to the system
How much of that available ram is being used (and the percentage; 6.92 is 11.09329…% of 62.38).
If the question is ‘why is not my whole RAM being made available?’ … its because it is reserved. Most notably for Video RAM (the memory allocated to the GPU) for integrated GPUs that have no memory of their own.
How much memory is reserved vs available to your operating system is variable along with the hardware, and sometimes even configuration options such as may be found in the BIOS.
