unfortunatley no rambus laying around lol...for those who dont know what rambus even is....here ya go
Rambus memory (RDRAM) is a revolutionary step from SDRAM. It's a memory design with changes to the bus structure and how signals are carried. Rambus memory sends less information on the data bus (which is 16 or 18 bits wide as opposed to the standard 64 or 72 bits) but it sends data more frequently. It also reads data on both the rising and falling edges of the clock signal, as DDR does. As a result, Rambus memory is able to achieve effective data transfer speeds of 800MHz and higher.
Another difference with Rambus memory is that all memory slots in the motherboard must be populated. Even if all the memory is contained in a single module, the "unused" sockets must be populated with a PCB, known as a continuity module, to complete the circuit.
Rambus DRAM modules are known as RIMM modules (Rambus inline memory modules). Rambus memory supports both ECC and non-ECC applications.
