海力士内存我大致介绍一下:

UDIMM(Unbuffered DIMM)
Features:
Without a buffer or register → faster latency
Low density modules only (Due to error issues)
Supports 2DPC and up to 2 ranks per DIMM
Main Application:
Desktop

SODIMM(Samll Outline DIMM)
Features:
Smaller than normal DIMMs
For systems with limited space issues
Main Application:
Notebook

RDIMM(Registered DIMM)
Features:
A register is placed between system memory controller and DRAM to control DIMM’s address and command signals
Added 8 bit parity signals for error correction
Supports x8, x4 DRAM / Supports 3DPC and up to 4 ranks per DIMM
Main Application:
Server

LRDIMM(Load-Reduced DIMM)
Features:
Register replaced with memory buffer to reduce load
Better latency and better fit for high density modules
Main Application:
Server

ECC UDIMM/SODIMM(Error Correction Code UDIMM/SODIMM)
Features:
Able to detect and correct data corruption
Reduces number of crashes
Main Application:
Server

VLP RDIMM/ECC UDIMM(Very Low Profile RDIMM / ECC UDIMM)
Features:
Height lower than normal DIMMs
Takes less space, better cooling, but not fit for high density modules
Main Application:
Server(Blade)
