Super Talent PC3-10600 CL8
With a model name that actually means something and a brand known for extreme overclocking capabilities, Super Talent's part number W1333UX2G8 2x 1 GB dual-channel kit is an easy choice even before we consider whether or not it's the "best" choice.
This is the same brand that rushed DDR3-1600 modules capable of overclocking beyond a 2 GHz data rate into the market before most competitors had even produced DDR3-1333. On the other hand, medium rated timings of 8-8-8-18 at an extra-high 1.80 volts instills far less enthusiasm for these "mid-speed" parts. Only testing will prove whether or not these can live up to Super Talent's great overclocking reputation.
Super Talent's SPD table doesn't include any DDR3-1333 (667 MHz clock speed) value, and the modules are instead electronically labeled as DDR3-1066 parts. This means that most systems will automatically configure DDR3-1066 values.
Super Talent is the only brand in this comparison to provide Intel XMP SPD extensions, which work like EPP (Enhanced Performance Profiles) familiar to DDR2 enthusiasts by allowing select boards to automatically configure higher-than-standard voltage for an overclocked setting. In this case, Super Talent allows its DDR3-1333 to be automatically overclocked to DDR3-1600 at an incredibly high 2.00 volts.
