The Adata 8GB DDR5 4800MHz U-DIMM RAM delivers blazing frequencies of up to 4800 MT/s, a major leap from the max. frequency of DDR4 modules (3200 MT/s). 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 enhance power supply stability. 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. 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. With on-die error-correcting code (ECC) this module can correct errors automatically in real-time to provide increased stability and reliability. The Adata DDR5 4800MHz RAM comes with a lifetime warranty.
