prestazioni ram

[lucaf]

La mia configurazione è:

1) P4 (800 bus) 2.8 mgh

2) 1 giga di ram ddr 400 (3200) divisa in due blocchi da 512 in dual channel

3) scheda madre gigabyte 8knxp con chipset intel 875p

4) hd di sistema WD raptor da 36 giga

5) cpu ht attivato

Ho provato a fare alcuni test sul sistema e il risultato per la ram è:

AIDA32: 4132 Mb/s il lettura e 1451 Mb/s il scrittura

Morale: cosa ne pensate di questi risultati?
SOno buoni?

Non capisco nel test Sandra, l'ultima voce
