1gb notebook memory "PC2-5300 667 vs PC2-4200 533" whats the difference??

Im looking at two different types of notebook memory on newegg,

PC2-5300 667

and

PC2-4200 533

What is the difference between the two? And why is the 533 one always more expensive??

To my knowledge, the 667 is just faster than the 533. So why is the 533 more expensive??

 

I am not sure why the 533MHz one is more expensive. It should be a little less than the 667MHz because it is slower than 667MHz.

Are they the same brand? Do you have a link?

I have seen this different, might be because of the fact that DDR2-667 sells faster.

 

I think production is now concentrated on DDR2-667 and at present there is spare stock because the manufacturers were expecting Vista to boost demand.

DDR2-533 is starting to have rarity value, like DDR SODIMMs.

I'm not sure why anyone wants to buy DDR2-533 since all the DDR2-667 SODIMMs that I have looked at include timing data called SPD for running at 533MHz. See the attached (but note that CPU-Z reports the base, not 2x, frequencies).

Thanks alot guys, this helped alot. So in conclusion, just go for the 667 and ignore the 533's. As for the link, just search in newegg or check the T60p memory configurations @ the Lenovo site.

By the way, where can I find some 2gb 667 modules? the only place I can find them is on newegg, and the selection is very limited. Where do I find these bad boys??

 

**I ment 2gb 667 notebook memory modules

 

There are links to 2GB modules in the notebook deals forum. You need a 64 bit operating system to address more than about 3GB.
