Advances in technology have resulted in smaller chips and smaller computer systems. Kingston was motivated to stay ahead of technology by developing smaller modules. The new low profile modules function exactly the same way, which is absolutely great news for the end users who can benefit from smaller systems and lower heat diffusivity. These modules follow JEDEC standard with less consumption of PCB board, about 40% less in height compared to the modules we see today.
Kingston begins phasing in new Very Low Profile (VLP) DIMMs for unbuffered DDR2 Desktop memory SKUs for ValueRAM and eventually the System Specific memory. Some of the best selling modules, such as ValueRAM DDR2-800 and DDR2-667, have adapted to the new VLP standard. The VLP stands 0.72" (18.3mm) high compared to the standard PCB height of 1.18" (30mm). The two designs are functionally equivalent and have the same electrical characteristic and interface. Kingston is committed to reducing industrial waste and providing greeners more eco-friendly products for the environment.
