What's the difference between RDRAM and SDRAM?
RDRAM stands for Rambus Dynamic Random Access Memory. SDRAM stands for Synchronous Dynamic Random Access Memory. The two memories are completely different memory technologies and are not compatible with each other. RDRAM is a unique design developed by a company called Rambus, Inc. RDRAM is extremely fast and uses a narrow, high-bandwidth "channel" to transmit data at speeds much faster than SDRAM.
The most important thing to know is that you cannot use RDRAM in a system designed for SDRAM or vice versa. The two types of modules are different sizes and shapes, so they won't even fit into the same memory slots. You should buy whichever memory type was designed for your system.
Can I mix RDRAM modules of different frequencies, or ECC/non-ECC into my system?
When mixing module frequency or error-correction code (ECC), most RDRAM systems will default to lowest frequency among the inserted modules. In addition, if any of the modules do not support ECC, then most system disables the ECC function.
Do I need to upgrade the memory modules in my PC systems in pairs?
Before purchasing, note whether your system takes 16 bit or 32 bit RIMM modules, and whether your computer is a dual-channel or 4-channel system. For 4-channel RDRAM chipsets and motherboards, memory module upgrades should be in matched pairs. For instance, to add 512MByte of memory into a dual or 4-channel system, two matched 256MByte modules should be inserted. For dual-channel RDRAM chipsets and motherboards, memory module upgrades should be in matched pairs. Please look at your PC or motherboard user manual for details. Please check with your motherboard vendor for detailed information.
