815100-B21 HP 32GB DDR4-2666 PC4-21300 ECC Registered Dual Rank x4 CL19 288-Pin 1.2V DIMM Memory Module

The "815100-B21 HP 32GB DDR4-2666 PC4-21300 ECC Registered Dual Rank x4 CL19 288-Pin 1.2V DIMM Memory Module" is a memory module from HP that is designed for use in server and workstation applications.

Here are some of the technical specifications for the module:

• Capacity: 32GB

• Memory Type: DDR4

• Speed: 2666 MHz (PC4-21300)

• Error Correction: ECC (Error Correcting Code)

• Rank: Dual

• CAS Latency: CL19

• Voltage: 1.2V

• Pin Count: 288-Pin

• Form Factor: DIMM (Dual In-line Memory Module)

ECC memory is a type of memory that can detect and correct errors in data stored in the memory module. This type of memory is typically used in mission-critical applications where data integrity is of the utmost importance.

The module is also Registered. Registered memory modules have a register between the DRAM and the memory controller which delays the command and address signals by one clock cycle, allowing for more memory modules to be used in a single system without overloading the memory controller.

The 32GB capacity of the module is high, which makes it suitable for high-performance servers or workstations with large workloads or virtualization requirements. The 2666 MHz speed provides fast data transfer and processing capabilities. Dual rank allows for more memory to be installed on the system, the CL19 latency is fast, and the 1.2V voltage is standard for DDR4 memory modules.

This memory module is compatible with HP server and workstations that support DDR4 memory and 288-pin DIMM memory modules.
