CentOS relatando menor memória total em comparação com outros na AWS

Eu tenho uma instância t2.medium em execução na AWS no CentOS 7 AMItop e notei freeque ela está basicamente relatando 3,45 GiB de memória total. Se eu iniciar uma instância com o AWS linux (acho que tentei o RedHat também), ela relata cerca de 4GiB de memória. Olhando pela web, não consigo ver mais ninguém dizendo por que isso aconteceria. Alguém sabe por que eles relatam de forma diferente ou se é um problema que pode ser corrigido?

CentOS: KiB Mem : 3619008 total, 1096408 free, 1218216 used, 1304384 buff/cache

AWSLinux: Mem: 4049884k total, 459488k used, 3590396k free, 11440k buffers

EDITAR

Também lancei um RHEL com 1GiB de RAM:

KiB Mem : 1015472 total, 620588 free, 73452 used, 321432 buff/cache

Então, agora com quase o mesmo sistema operacional, mas relatando detalhes diferentes, presumo que haja algum bug nesta versão da AMI?

Desativei o Kdump e recuperei um pouco de espaço, mas ainda faltam ~ 200 MB.
