upgrading memory question?

[verg_santos]

I have a VGN-FS415E 512MB DDR2-SDRAM 400 Mhz. Can I use 2 x 1 GB DDR2-SDRAM 667Mhz to upgrade?

Yup should be fine... at most, it will just downclock the ram to whatever the rest is running (if slower)
But it will work fine... providing the machine supports 2gb ram in total
