PDP Systems Patriot PC2-4200 DDR2 XBL Memory
 

"Called the Patriot DDR-2 eXtreme Bandwidth and Latency Kit, each of these 1GB PC2-4200 XBL sticks of memory have official timings of 3-2-2-4. When those timings are loosened up to 4-3-3-12, PDP Systems PC2-4200 XBL RAM is almost able to 'fly' at 700 MHz, or PC2-5600 speeds! If you're wondering what "XBL" stands for it, it's the acronym for "eXtreme Bandwidth and Latency," and looking at the specs for these 1GB modules... it sure does look that way!"
