I was just looking for a new PC, and my first requirement was a 
motherboard that could go over 4 Gig....
My second requirement was an Athlon64.

Can you think of a situation that needs an 8 byte count?
Or do you just want the size increased on general principles?

Do you think that increasing the count to 8 bytes would be a problem
