Our Summary and Conclusion
Performance Summary: Corsair's new Dominator TWIN2X2048-10000C5DF memory was the fastest of the three memory kits we tested here, thanks to its combination of high-capacity, relatively low latency, and ultra high frequency. In SANDRA's memory bandwidth and latency benchmarks it put up the highest bandwidth numbers and some of the lowest latencies, and it similarly posted the highest scores in the PCMark05 and F.E.A.R. benchmarks as well.
As PC enthusiasts, we can't help but be impressed by Corsair's Dominator TWIN2X2048-10000C5DF memory kit. The TWIN2X2048-10000C5DF kit is arguably the fastest matched pair of DDR2 memory modules on the market today. This memory also features an innovative cooling solutions (DHX), support for EPP, and throughout our testing it was rock-solid stable in every configuration. It wasn't until overclocked and pushed to almost 1.3GHz that this memory faltered, and even then it could very well have been the nForce 680i SLI motherboard holding us back.
It's not all good news, however. A quick search using Pricegrabber yielded only a single vendor selling this memory, and it was priced at a wallet-busting $748. We're sure this price is a reflection of this memory's limited available at the moment, but that price is almost double what most 4GB memory kits are currently selling for and it's obviously much higher than the price of other high-speed 2GB memory kits as well. If you want the highest clocked DDR2 memory currently available in your PC, cost be damned, Corsair's Dominator TWIN2X2048-10000C5DF memory kit is it. But you could save a fortune by sacrificing a few MHz and going with one of the many PC2-8500 or faster memory kits on the market today, including Corsair's own TWIN2X2048-8500C5DF.
