Non-Stacked IC's: Ramjet uses a Non-Stacked module for the DDR3-1066 modules for the iMac. The cheaper stacked IC variety of SO-DIMM draws more power, which increases heat and can cause increased errors. Ramjet ONLY uses premium non-stacked chips.

1066 vs. 1067? The correct name for this memory is DDR3-1066. But since it runs at 1066.66Mhz, the Apple System Profiler reports it as 1067Mhz.
