Lowest Latency Test Results

DDR3-1333 Speed and Latency Shootout
By

Using a relatively safe 1.80 volt setting, the DDR3-1333 test modules reached the following "best stable timings" at 1600 MHz, 1333 MHz and 1066 MHz data rates.

OCZ pulls amazing 4-4-3-9 timings at a 1066 MHz data rate, while the potentially lower-cost Wintec AMPX finds itself in a three-way tie with both OCZ kits at DDR3-1333. Overclockers looking for the lowest latency might prefer Super Talent's 7-6-6-13 timings at a 1600 MHz data rate.

Patriots DDR3-1333 had reached a stable 1652 MHz data rate on Gigabyte's top-end P35 motherboard, but the Asus Maximus Extreme's X38 chipset appears to be just a little more finicky. The modules didn't even reach a 1600 MHz data rate on the newer platform, but tied for second place in DDR3-1333 latencies.

Lower latencies are meant to improve system performance, so let's consider what the benchmarks can tell us.
