RDRAM
RDRAM is a wide-channel device. They transfer data only 16 bits (2 bytes) at a time (plus 2 optional parity bits), but at much faster speeds. RIMM typically runs at 800MHz, so the overall throughput is 800 × 2, or 1.6GB per second for a single channel—the same as PC1600 DDR SDRAM. Dual-channel PC800 RDRAM is also currently the fastest type of PC memory, followed by PC2100 DDR SDRAM. Whether your board supports (requires) dual-channel RDRAM is dictated by the motherboard chipset; currently, the Intel 840 and 850 chipsets support dual-channel RDRAM.
