*Limited lifetime warranty valid everywhere except Germany and France, where warranty is valid for ten years from date of purchase.
Note: Product performance and efficiency improvements are noted as comparisons between DDR3 and DDR4 memory technologies at their introduction. When it was introduced, DDR3-1066 operated at 1.5V and had an estimated component density of 8Gb, compared to DDR4-2133, which will operate at 1.2V and have an estimated component density of 16Gb. When voltage reductions and all other energy-saving DDR4 features are factored in, DDR4 modules are projected to consume up to 40% less power.
**Note: Not all densitites and speeds will be available at launch. DDR4 densities and speeds will increase as DDR4 technology matures.
