Why is the speed of this RAM module shown as 4800 MT/s instead of 4800 Mhz?
When it comes to measuring DDR RAM speed, MT/s and MHz are used interchangeably, which is not actually correct.
This module offers a bandwidth of approximately 38.4 GB/s per DIMM at its full transfer rate of 4800 MT/s × 64 bits, delivering server-grade performance suitable for demanding workloads. It is ideal for enterprise-class applications such as web servers, databases, and virtualization, with support for 2-DIMM-per-channel server motherboards. Additionally, it is widely adopted by major system integrators like Dell, HP, IBM, and Supermicro, and is typically backed by lifetime or multi-year warranties from various vendors.
