The new Power8 systems started shipping last Friday, and this week, in our ongoing coverage of the new hardware and software technologies embodied in the systems, we are going to take a look at the memory subsystems in the new machines. There are a slew of new technologies that have been added to the Power8 machines so the memory can keep the processor cores well fed and humming along through their work.
The Power8 chip has two DDR3 main memory controllers, one on either side of the chip. Some of the DDR interfaces that were previously on the Power7+ controller
