Salve.
Vorrei sottoporvi un piccolo dilemma che mi affligge da qualche giorno.
Ho un pc in cui sono montati 4 banchi di ram da 512MB per un totale di 2GB.
I moduli sono PC3200 DDR/400. Nel bios sembrano però riconosciute come PC2700 DDR/333.
Informazioni prese dal BIOS:
Scheda Madre: HP d530 SFF(DG758A)
Velocità Processore 3200/800 MHz
Processor Stepping F34
Dimensione Cache 20/1024 KB
Dimensione Memoria 2048 MB DDR/333 MHz (Dual Channel)
BIOS 786B2
Eseguendo un memory test con memtest86+ ottengo le seguenti info:
Memory: 2048MB 2135 MB/s
Chipset: Intel i848/i865
FSB 199 MHz
RAM 159 MHz (DDR319)
CAS 2.5-4-4-7 Dual Channel (128 bits)
Da sistema operativo (ubuntu 10.04) se lancio
sudo dmidecode -t memory
ottengo:
# dmidecode 2.9
SMBIOS 2.3 present.

Qual'è secondo voi la reale velocità delle RAM? C'è un modo più sicuro per conoscerla?
