Hello~
I may have a similar problem but not really sure. I just purchased pc2-4200 (533) and speccy is reporting it as being pc2-6400 (800).

Still, I think in slot#2 speccy reported it as pc2-4300 when I believe the sticker on the ram chip read
pc2-4200.
The pc2-6400 reported by speccy may or may not be pc2-6400. I just bought this and maybe they tagged it wrong@pc2-4200 at the factory.
