9 High capacity: In DDR3, DIMMs from 2GB up to 64GB were available, in DDR4, capacity starts at 4GB up to 64GB and higher. This means, you're able to run up to 3TB of memory in a DL380Gen9 system with the release of 128GB DIMMs. Runs cooler: DDR4's improved thermal character-istics allow each DIMM to run at lower tempera-tures then DDR3. DDR4 does its part to be neutral on climate change.Additional features worth mentioning include Write Data Cycle Cyclical Redundancy Check gives you better error detection capability and reliability but won't be supported on server platforms because of ECC. Data Bus Inversion will reduce the power consumption and improve signal integrity. CA (Command/Address) Parity is a method to verify the integrity of command/address transfers (expected to be used eventually when U-DIMMs, or unregistered [unbuffered] DIMMs become available).When selecting DDR4 memory, options will include R-DIMMs (higher performance, lower latency) modules: 4GB/8GB/16GB data rates: 1333/1600/1867/2133 MT/s LR-DIMMs (higher bandwidth, higher capacity) modules: 16GB/32GB/64GB data rates: 1333/1600/ 1867/2133 MT/sThese materials are © 2014 John Wiley & Sons, Inc.
