Explanation

SDRAM (Synchronous DRAM) is a single-data-rate memory technology from the late 1990s that predates the dual-channel memory architecture. Dual-channel mode was introduced alongside DDR (Double Data Rate) SDRAM, and the chipsets and memory controllers designed to support it were built for DDR and later generations. SDRAM lacks the architectural support in modern chipsets for dual-channel operation. DDR2 and DDR3 were explicitly designed with dual-channel support as a core feature. RAMBUS (RDRAM), while unusual, used a multi-channel architecture by design. SDRAM is therefore the least likely to operate optimally-or at all-in a dual-channel configuration.
