Patriot SO-DIMMs - Speccy ID

Can anyone explain this result -

I've just inserted 1GB SO-DIMMs in my laptop, I wanted to check they'd gone in ok so I ran Speccy v1.26 to have a look at the details

One of the SO-DIMMs it ID'd as a Patriot, but oddly it didn't return the p/n. As far as I'm aware Patriot have made only one p/n with PC2700 spec that's the PSD1G333S.

Why isn't Speccy returning the p/n ? Would it not being present in the module's firmware explain this or is it something to do with Speccy ?
