salve a tutti

ho un portatile hp dv5194 acquistato ad agosto 2006.

siccome voglio upgradare la mia ram, mi domando se questo portatile supporta le ddr2 a 667 mhz

vi allego le informazioni tratte da cpuz

qualora siano supportate le ram @ 667 mhz, è meglio prendere preferire queste case latency 5 o ram 533 mhz case latency 4?
