More Engergy Efficient This next-gen memory module operates on just 1.1V, making it 8% more power-efficient than DDR4. What's more, it features a built-in Power Management IC (PMIC) to enhanced power supply stability. Capacity Doubled This memory module's architecture allows for more memory bank groups and banks. With the same area, more bank groups can be packed into the module, doubling what was possible with DDR4, giving you higher capacities. Improved Stability With on-die error correcting code (ECC) this module can correct errors automatically in real-time to provide increased stability and reliability.
