Memory Rating Guide

     One of the biggest things that confuse people these days is the good old PC rating on DDR memory. Even worse, most people don't realize that any memory over PC3200 hasn't been JEDEC (Joint Electron Device Engineering Council) approved. Even though PC3500 or PC4400 hasn't been official accepted, it is usually quite capable of running at those specs. However, because there is noting regulating this memory, you're Mom & Pop's PC4400 or other non standard memory may actually be overclocked PC3200. The bottom line is to always buy memory from a trusted source.

     Below is a chart that clearly shows a breakdown of the PC rating to DDR speed to actual bus speed. I hope this helps!
