Triple-channel architecture

Operation

DDR3 triple-channel architectonics is acclimated in the Intel Core i7-900 alternation (the Intel Core i7-800 alternation alone abutment up to dual-channel), and the LGA 1366 belvedere (e.g., Intel X58). AMD Socket AM3 processors do not use the DDR3 triple-channel architectonics but instead use dual-channel DDR3 memory. The aforementioned applies to the Intel Core i3, Core i5 and Core i7-800 series, which are acclimated on the LGA 1156 platforms (e.g., Intel P55). According to Intel, a Core i7 with DDR3 operating at 1066 MHz will action aiguille abstracts alteration ante of 25.6 GB/s if operating in triple-channel interleaved mode. This, Intel claims, leads to faster arrangement achievement as able-bodied as college achievement per watt.9

When operating in triple-channel mode, anamnesis cessation is bargain due to interleaving, acceptation that anniversary bore is accessed sequentially for abate $.25 of abstracts rather than absolutely bushing up one bore afore accessing the next one. Abstracts is advance amidst the modules in an alternating pattern, potentially tripling accessible anamnesis bandwidth for the aforementioned bulk of data, as against to autumn it all on one module.

The architectonics can alone be acclimated if all three, or a assorted of three, anamnesis modules are identical in accommodation and speed, and are placed in three-channel slots. If two anamnesis modules are installed, the architectonics will accomplish in dual-channel mode.10
