DDR3-1333 Speed and Latency Shootout

SPD Timing Comparison

Though we will find the lowest stable timings at increased voltage in our later "lowest stable latency" tests, a chart comparing all the rated timings should help determine which market each module set is really targeting.

Aeneon and OCZ both provide SPD values in excess of their rated speed, while Super Talent uses Intel XMP automatic overclocking capabilities to go even higher. Kingston and PDP Patriot instead target the low-latency crowd, but OCZ appears to shoot for both markets with both of its products.
