Existing information about LGA 1156 processors characteristics assert that their built-in memory controller will support dual-channel DDR3-1333 memory . LGA 1366 processors officially support triple-channel DDR3-1066 memory ; however, overclock allow them to work also in regimes of more than DDR3-2000.
Associate reported the overclocking potential of memory controller on lynnfield processors based on engineering model example.Using two memory DDR3-2000 from OCZ production (elpida hyper microcircuits), associates could reach the regime DDR3-2352 after a substantial increase in the vcore voltage. Note, that early Bios revision does allow to separately increase the voltage on memory controller which forms part of the processor (uncore).
