Mainstream-Ready? DDR3-1600 Shootout

Buffalo FireStix FSI1600D3G-2G (FSI1600D3G-K4G)

Buffalo sent two separate packages of its high-end FireStix FSI1600D3G-2G modules, rather than the –K4G twin pack. We expect to see a lot of companies make the switch back to individual packages as we approach the launch of Intel’s next-generation triple-channel memory configuration, but Buffalo appears to be ahead of the market this time.

However, Buffalo doesn’t lead the market in distribution. We only found the –K4G twin pack in Japan and the -2G single modules in Germany. To the best of our knowledge, today’s comparison is the first time these parts will appear in the United States and we can’t even quote a U.S. dollar price. Until we do find these in the broader market, we’ll have to treat this as a preview set.

CPU-Z detects these as DDR3-1333 modules, which implies that they consist of lower-speed components that have a factory overclock rating. There’s always the possibility that these really are DDR3-1600 parts of higher rated voltage, and that the lower speeds were simply chosen to make sure any system would boot at default voltage. Our overclocking test will reveal more about how well FireStix FSI1600D3G-2G modules compare to competing parts.
