Generally speaking a Registered module is used in Server platforms. - The Register is designed (loosely speaking) to act as a sort of a processor on the module to help dictate actions as the memory module works. An "unbuffered" module goes into a desktop PC.. these are the "vanilla" modules, Desktops are the most simple and least demanding. An SoDIMM or low profile DIMM goes into Laptop computers.. simply because the module is literally smaller. Sometimes heat considerations are part of the design. These modules also are defined by the configuration of the memory components of the module, and the way the module will read the memory chip. Using the correct configuration helps the module perfoem. X4 is for Registered / FBDIMM's.. into servers X8 is for Desktop PC's X16's are for Laptops. Keep in mind there are exceptions in every case.. but this is generally how it works. Hope this helps!
Unbuffered DIMM.
It is called an "unbuffered dimm"
Registers represent the number of memory locations. A 2K memory chip has 2x1024=2048 memory locations. Hence there are 2048 registers in a 2K memory.

Registers are memory locations on the microprocessor itself (not in main memory). In RISC architectures generally most operations (add, multiply, etc) must take there input from registers and write their output to a register. Since registers are located directly on the microprocessor, they represent the fastest form of memory in the computer, and also the type of memory available in the least quantity.
RISC machines operates on registers to prevent in large amount of interactions with memory

The fastest type of memory on a computer is the registers that form the execution model of the processor.
The opcode fetched from the memory is being decoded for the next steps and moved to the appropriate registers. Fetch operands from memory if necessary: If any operands are memory addresses, initiate memory read cycles to read them into CPU registers.
