Velocità RAM ridotta: da 333MHz a 166 MHz

[swappy]

Ciao a tutti.

Ho un vecchio "notebook" Sony Vaio VGN-FS640 a cui ho fatto l'upgrade della memoria.

Ho montato due ram DDR SODIMM Corsair da 512 MBytes PC2700 (Corsair VS512SDS333)

Però la velocità rilevata con HWINFO è di 167MHz

Sul BIOS non c'è niente da porte settare...

Come mai?

Questi i valori che trovo:

HWiNFO32 Version 3.82-1300
