Description
Overview of the 840758-V91 HPE 32 GB 2666 MHz Pc4-21300 Registered Cl19 DDR4 SDRAM Memory Module
The 840758-V91 HPE 32 GB 2666 MHz Pc4-21300 Registered Cl19 DDR4 SDRAM Memory Module is a high-performance memory module designed for use in HPE servers. It has a capacity of 32 GB and operates at a speed of 2666 MHz.
The memory module uses the DDR4 memory standard, which is the latest generation of memory technology and offers higher performance and improved power efficiency compared to previous generations. It also has a registered (RDIMM) form factor, which is commonly used in servers and workstations for improved reliability and error correction.
This module also features CL19 latencies, which represent the time delay between the memory controller sending a command and the memory module responding. Lower CL numbers typically indicate faster memory access speeds.
The Pc4-21300 in the name of the module refers to the PC4 standard, which is the latest standard for DDR4 memory and stands for ‘performance level 4’. The number “21300” represents the transfer rate of the memory in MT/s (Mega Transfers per second) which is 21,300MT/s.
