ram su sistemi a 32 bit

[20111954]

buona pomeriggio, uso lubunto sia su un portatile che su un fisso, entrambi a a 32 bit, come fare riconoscere e quindi sfruttare oltre 3 gb di ram?

[pachisapiu]

purtroppo nei repo ubuntu non sono più presenti i kernel pae quindi la vedo dura

[trekfan1]

Tutti i kernel a 32bit sono già PAE....

[20111954]

su un desktop ho installato xp e lubuntu su due hd, e un vecchio pentium 4 con un processore da 3.00 ghz e 4gb di ram, è a 32 bit, se trovassi il modo di fare leggere e quindi accettare i 4 gb di ram su windows forse lubuntu potrebbe accettare anche i 4 gb di ram

i due sistemi sono indipendenti uno dall'altro ...

Tutti i kernel a 32bit sono già PAE....

a quanto mi risulta l'unico kernel pae nei repo di ubuntu è per architettura armhf

si i due sistemi sono indipendenti xp su un hd e lubuntu su altro hd

[axilot]

I kernel non pae gestiscono fino a 4gb di ram per cui nel caso specifico il problema non sussiste, qualsiasi distro tu voglia installare.
(tutti quelli di ubuntu sono pae semmai devi cambiare distro se la tua cpu non supportasse il pae)
Se non ti riconosce 4gb di ram, il problema potrebbe essere la scheda madre o la ram stessa.

per avere la certezza di quanta ram legge ed utilizza quale comando devo dare?

per aggiornamento intendo il bios

[ubuz]

no, scusa, quello che ho postato è un estratto del comando
[sudo lshw]
l'ho preso dal risultato che hai messo, non sono comandi da inserire

edit:

per aggiornamento intendo il bios

non credo ti serva un granché, già ti riconosce come dovrebbe la ram disponibile

[20111954]

girando su internet ho trovato questi comandi che assicurano la risoluzione del problema, c'è da fidarsi, posso darli dal terminale?

Aprire il terminale;
Digitare sudo apt-get install linux-restricted-modules-server e premere il tasto Invio;
Digitare sudo apt-get install linux-headers-server e premere il tasto Invio;
Digitare sudo apt-get install linux-image-server linux-server e premere il tasto Invio;
Riavviare il PC;

[ubuz]

a quale versione si riferisce?
dove l'hai trovata?
