Intel's DH67BL motherboard supports non-ECC DDR3-1066/1333 memory in a dual
channel configuration across four 1.35v DIMMs. The largest memory density for
64-bit operating systems is 32GB, for Windows 32-bit you're capped at 4GB
Socket LGA1155 for Intel 2nd-Generation Core
i3/i5/i7 2xxx-series processors.
Like all Intel H67 platforms, the Intel DH67BL
motherboard accommodates Intel socket LGA1155 2nd Generation 'Sandy Bridge'
Core i3/i5/i7 2xxx-series processors which contain an Intel HD 2000/3000
integrated graphics core. The CPU socket is not backwards compatible
with socket 1156 CPUs, however heatsinks are inter-compatible
between socket 1155 and socket 1156 motherboards.
