So-called "Green" products are all the rage lately and G.Skill has decided to cash in on this trend with their ECO series of DDR3 memory modules. Designed for Intel's Core i5 and Core i7 Lynnfield processors, the ECO series operates at a low 1.35vdimm versus your typical 1.65vdimm modules. This particular kit, the F3-12800CL7D-4GBECO, sports 7-8-7-24 timings at 1600MHz while scraping by with a meager 1.35vdimm. It feels like only a year ago we were blasting 2.3vdimm through DDR3, now we are down to 1.35vdimm!
