Athlon 64 Memory: Rewriting the Rulesby Wesley Fink on October 1, 2004 12:45 AM EST

Highest Memory Speed
The only time that we have really seen DDR600 performance in the past has been with a single DIMM on the Socket 754 Single-Channel DFI LANParty UT nF3-20Gb. The new Socket 939 Athlon 64 test bed will force a rethinking of what constitutes high memory speed performance. Two of the six memories, the Geil Ultra X and OCZ 3200 Platinum Rev. 2, reached DDR600 in our tests, and most others came very close to that memory milestone with highest speeds in the DDR590 to DDR600 range.
The latest memory based on Samsung TCCD chips and Micron chips is clearly performing much better on the Dual-Channel Socket 939 Athlon 64 that we expected. Both memories are faster on Athlon 64 when combined with a robust power supply. The latest Hynix DT-D5 is also performing very well on A64, with performance comparable to Intel test bed results. Since the Hynix-based 3700 Gold Rev. 3 reaches the same overclock at either 2T or 1T Command Rate, it competes very well when we look only at benchmarks run at the highest memory speed that we could achieve with each
