[BUG] Memory size doesn't show the number I expect #2026
Description
Read the FAQ first
- I have checked the FAQ but the issue is not covered
Description
I have a machine with 64 GiB of RAM installed. Fastfetch displays it as 62.40 GiB.
I tried changing binaryPrefix, thinking it was just a matter of GiB vs GB, but with si I get 67.00 GB, with jedec 62.40 GB.
--format json gives:
...
"type": "Memory",
"result": {
"total": 67004215296,
...Which converted from B to GiB, indeed gives 62.40.
cat /proc/meminfo gives: MemTotal: 65433804 kB
For reference, htop also shows 62.4G.
However, if I go in GNOME Settings, then System > System Details, it displays:
Memory
64.0 GiB
I have no idea why GNOME is the only one that gets it right, and would love for fastfetch to get it right too.
