Eu tenho alguma RAM falhando em um servidor e eu corri o dmidecode para descobrir com que tyoe de RAM eu precisava substituí-lo.
O servidor tem 6 slots de RAM, dos quais 4 estão em uso. Quando eu executo o dmidecode, isso é o que eu recebo.
dmidecode 2.10
SMBIOS 2.4 present.

Alguém sabe por que ele mostraria 8 slots, com 4 vazios em vez de 6 slots com 2 vazios? Além disso, mas meus registros e outras ferramentas, o servidor tem 16GB e não 8GB nele atualmente.
grep MemTotal /proc/meminfo
MemTotal: 16435808 kB
A placa é um Tyan S5372-LC, rodando o CentOS 5.4 x64.
Além disso, meu log de erros está mostrando erros no banco 6. Existe alguma maneira de determinar em qual banco de slots 6 está a via: dmidecode?
Desculpe, não posso comentar a partir de agora, mas a mensagem com o erro 6 do banco é:
EDAC MC0: CE row 0, channel 0, label "": (Branch=0 DRAM-Bank=6 RDWR=Read RAS=1755 CAS=2492, CE Err=0x2000 (Correctable Non-Mirrored Demand Data ECC))
