Correlation between PCxxxx and xxxMhz on RAM

[joltman]

A friend and I were talking about RAM, and we were trying to figure
something out. With the DDR RAM, what exactly is the correlation
between the PC #'s (ie PC2700) and the Mhz (ie 333 Mhz) Why not just
refer to them by Mhz like before? Just to confuse us ? I noticed
that if you divide the PC # by the Mhz it is in the vicinity of 8, but
it's not always the same number.
Any help to lessen the confusion would be appreciated.
Thanx

Hmm, DIMMs are eight bytes (64bits) wide. Odd that correlation. ;-)
