Explanation/Reference:
* RDIMM
RDIMMs add a register, which buffers the address and command signals.The integrated memory controller in the CPU sees the register instead of addressing the memory chips directly.
* LRDIMM
Load Reduced DIMMs replace the register with an Isolation Memory Buffer (iMB by Inphi) component. The iMB buffers the Command, Address, and data signals.The iMB isolates all electrical loading (including the data signals) of the memory chips on the (LR)DIMM from the host memory controller.
* UDIMM
UDIMM (unregistered memory) is a type of memory chip used mostly in desktop and laptop computers. More commonly called unbuffered memory, UDIMMs run faster than registered memory (RDIMM) and cost less, but are not quite as stable as RDIMMs.
* NVDIMM
A Non-Volatile Dual In-line Memory Module (NVDIMM) is a computer memory RAM DIMM that retains data even when electrical power is removed either from an unexpected power loss, system crash or from a normal system shutdown. NVDIMMs can be used to improve application performance, data security, system crash recovery time and to enhance SSD endurance and reliability.
