RAM Lenovo Essential G500

[aRaKaNoiD]

Ciao a tutti,
dovrei ampliare la memoria del mio portatile acquistato un paio di anni fa.
Ho visto che esistono varie tipologie di ram e non vorrei sbagliare.

Dovrei smontare il pc per vedere che ram è inserita? oppure c'è un altro modo per sapere informazioni sulla ram?



non so se può aiutare:

pier@Lenovo-G500:~$ sudo dmidecode --type memory

Scarica HwInfo fallo partire e cliccando sul menu a tendina "memory" a sinistra ti mostra che moduli di ram sono montati ed anche tutte le caratteristiche

[Chimico_9]

se puoi avviare un windows : HWinfo o cpu-z
altrimenti su Linux non ne conosco di questi programmi

il pc non ha lo sportellino sul fondo?
secondo me fai prima a svitare una vite...

cmq
è installato 1 banco da 4GB, DDR3, 1600MHz
quello che rimane da sapere (e che sul report non è scritto) sono latenza e voltaggio

[aRaKaNoiD]

In teoria già con quelle info sarei in grado di comprare il banco RAM da 8 GB corretto? Xke ho visto DDR3 e DDR3L...
Cmq tra mezz'ora circa installò quel programma su windows e vi mostro le info.

sulla base di questi dati da voi richiesti potrei comprare una di queste 4?
[Edit]


Se non c'è grande differenza di prestazioni sceglierei una delle ultime due visto che sono in italia e mi servirebbe al più presto.
