Here is the first picture of a DDR4 SO-DIMM module, exhibited by Crucial at its 2014 International CES booth. The company revealed its first DDR4 server memory lineup, as its DDR4 SO-DIMMs, targeting micro-servers, and future notebooks, tagged along. DDR4 DIMMs and SO-DIMMs measure roughly the same as their standard (full-height) DDR3 counterparts, except that the index notch is positioned differently. DDR4 promises to up memory bandwidths, densities, and energy efficiency. Intel's next-generation HEDT (high-end desktop) platform could be the first client platform to support DDR4. Crucial unveiled the first Ballistix-branded DDR4 memory module, targeting some of those systems. DDR4 memory modules could start at speeds of up to 2133 MT/s, and module voltages as low as 1.2V. Compare those to the 1066 MT/s and 1.8V DDR3 started off with!
