Yesterday, AMD held a press presentation in Munich, Germany to update journalists about its upcoming K10 processor. AMD’s Giuseppe Amato, Technical Director Sales and Marketing EMEA, had a few minutes to talk about the architecture at length. The integrated memory controller (IMC) will get a few new features in the K10 core. When utilizing multiple memory modules, along with proper BIOS implementation and mainboard routing, the IMC can access memory in 64-bit channels (72-bit if you use ECC). This way it is possible to read and write data simultaneously, or improve efficiency for irregular access patterns which increasingly occur in a quad-core environment. This feature is available on AM2+ and F+ boards; on “old“ socket AM2 and F boards the usual 128-bit dual-channel mode is available.
