Kingston HyperX PC2-6400 C3

King sticks that would be at home in any performance enthusiast’s system.

With DDR2-800 4-4-4-x the new norm for ‘low-latency’ memory, Kingston has
taken it one step further, offering DDR2-800 modules with lightning quick 3-3-3-10 latencies. Many overclockers have been running these specifications for months now, but this is a first commercially.

The modules are guaranteed to do the tight 3-3-3-10 timings at DDR2-800 frequencies. This indicates high-binned modules designed specifically for low-latency. As such, you’d expect considerable overclocking at low latencies.

To test the sticks, we set the BIOS to run the memory in unlinked mode on our EVGA 680i motherboard. With the CPU FSB set to 266MHz, the processor multiplier at 11, memory voltage at 2.35V and the timings forced to 3-3-3-10 2T, we progressed to Windows.

The modules scored 1mins 38.750s in Super Pi 4M, followed by 29.015s in wPrime 32M. Rounding out the stock scores, the modules came through with 9098MB/s, 6086MB/s and 52.9ns in the Everest memory read, write and latency benchmarks.

Knowing we had some quality sticks on our hands, we decided to test the overclocking for both CAS 3- and CAS 4-based timings of 3-3-3-10 and 4-4-4-12. We managed DDR2-867 with 3-3-3-10 2T latencies and DDR2-1142 with 4-4-4-12 2T. At DDR2-1142 4-4-4-12 2T, the kit excelled.

With the CPU FSB set to 333MHz, the CPU multiplier lowered to nine and the memory at the previously stated DDR2-1142 4-4-4-12 2T timings, the modules scored 1mins 36.609s in Super Pi 4M and 29.062s in wPrime 32M. In Everest’s read, write and latency benchmarks, the sticks scored 9134MB/s, 6085MB/s and 49.8ns respectively.

Offering high performance at stock and overclocking further than you can throw your uncle Barry, these modules are perfect for a system tailored for low latencies. The Kingston HyperX PC2-6400 C3 kit will be at home in any performance enthusiast’s system.
