Quick question regarding PC8400 vs PC8500

I was looking to upgrade my RAM from 2x1GB to 2x2GB (2GB - > 4GB) and I currently have these in my system:

Looking at a couple online vendors, I've seen some 8500 2x2GB sets selling for way less than the 6400s. In particular, I found these:

Is there something wrong about the second pair I listed or have RAM prices dropped that low recently?

PC8500 = DDR2 1066
PC6400 = DDR2 800

I don't know what PC8400 is?

Sorry I had a small typo

There's nothing wrong with them. I'm not quite sure what you are asking though.
