With Intel's Montevina Centrino 2 platform just a couple months away, DDR3 SO-DIMM modules are beginning to show up in the market. Walton Chaintech has just released DDR3 1066 SO-DIMM modules which meet DDR3 JEDEC standards and operate with a working voltage of just 1.5V.
This is where DDR3 modules are really fitting for a notebook, as not only do they have a much higher ceiling, but the lower power consumption reflects on overall battery life as well.
Global memory provider Lexar/Crucial has also come forward with an announcement supporting the release of some DDR3 SO-DIMM modules today. The Crucial DDR3-1066 SO-DIMMs are available in 1 and 2GB densities, also operating at a mere 1.5V.
