Because we didn’t have a single brand of modules to represent all three test capacities, we were forced to use different brands to represent different sizes. Crucial Ballistix filled the 3 GB void with three 1 GB DDR3-1600 modules, while Kingston’s 2 GB DDR3-2000 modules were used in 6 GB and 12 GB configurations. In order to assure performance parity, memory timings were matched at 8-8-8-24 and 1N, and all available BIOS sub-timings were “locked” at those detected for the slowest (Crucial) modules.

We also updated several of our benchmarks to 64-bit compatible versions, ahead of the full-site transformation that’s scheduled to take place soon. Because today’s article preceded any unilateral agreement, further changes in the suite are likely to accompany future articles.
