... The HYS64(72)V8000GU-10 are industry standard 168-pin 8-byte Dual in-line Memory Modules (DIMMs) which are organised and high speed memory arrays designed with Synchronous DRAMs (SDRAMs) for non-parity and ECC applications. The DIMMs use eight SDRAMs for the organisation and an additional SDRAM for the organisation. ...
