Right along with Kingston, OCZ announced today the launch of two sets of DDR3 RAM. Targeting Intel's Bearlake chipsets, OCZ is offering PC3-8500 and PC3-10666 modules, each available in 1GB or 2GB dual channel kits. As usual, they come with all the things you expect from OCZ memory kits, such as the XTC heatsink and their standard warranties.
Pricing isn't being made available, but likely they will be quite pricey at first as all new technologies are. Regardless, we should expect many other manufacturers to start offering DDR3 soon as well.
