The DDR memory listed in this overclocking chart are listed in chronological order with memory size, stock speed rating and maximum speed reached when overclocking. Again your results may vary but this should give you an idea at what your DDR memory should be able to do. Note there are certain classes of memory which overclock very well like Winbond's BH-x series and Hyundai's D43.

Next up are Intel motherboards, broken up by socket, here we go!
