Bit-Tech published the second part of their 4GB DDR3 memory roundup

All in all, the Elixir is a unique, low power, low profile performance solution but its pitiful 12 to 24 month warranty and inability to overclock that far means the Corsair from Part One of this round up is a better value product.

The Patriot Viper memory, on the other hand, is certainly great performing and good looking, but the Viper heat "shields" are not technically as excellent as other solutions. What's more, the higher rated voltage means it struggles at the extreme fringes, unless that is, you're really prepared to throw a lot of cool air and voltage into it which is covered by a lifetime warranty anyway - the good thing is that although its rated voltage is high, it boots at up to 1,600MHz with just 1.65V, meaning that it'll be fine in an X58-based system.
