Overclocking And Under-Latency Results

Six Low-Voltage Dual-Channel 8 GB Memory Kits, Overclocked
By

Though memory typically responds to added voltage by facilitating higher data rates, G.Skill’s 1.25 V Sniper SR2 topped out at 1.35 V. Unlike other modules in today’s test, 1.50 V offered G.Skill no further overclocking headroom.

Super Talent’s W160UA4GML tops the overclocking charts, though these specific modules are custom-order parts. Geil follows up with a true production product that only Europeans and Asians can purchase locally. Here in the States, look to U.S.-based firms to find memory without the distribution woes. Of these, Kingston allowed us to pick the DDR3-2133 multiplier.

The big surprise in overclocking was that Crucial’s factory-direct modules didn’t reach the same DDR3-2133 CAS 9 overclock of their retail counterparts. These kits carry the same part number, but were likely produced on different days. Better luck next time, Crucial?

Crucial does take a big lead in low-latency support, in spite of the missing DDR3-2133 data. Secondary and tertiary timings that also affect performance were left to auto-configuration values and could still play a significant role in performance tests.
