Description
Introduction to the HPE P43789-B21 Memory Module
The HPE P43789-B21 is a memory module designed for use in HPE ProLiant servers. It is a DDR4-2666 32GB (1x32GB) Registered DIMM memory module that operates at a speed of 2666 MHz and has a capacity of 32GB. It is a dual rank memory module, which means that it has two sets of memory chips on each side of the module. It is also registered, which means that it has a register chip on the module that controls the flow of data between the memory module and the memory controller. This module is compatible with a number of HPE ProLiant server models.
Capacity: 32GB of ECC Registered DDR4 SDRAM
Yes, that is correct. The HPE P43789-B21 memory module has a capacity of 32GB, and it uses ECC (Error Correction Code) Registered DDR4 SDRAM (Synchronous Dynamic Random Access Memory) technology. ECC memory is a type of memory that can detect and correct errors that may occur in the data stored in memory. This is important in server and other mission-critical applications, as it helps to ensure the integrity of the data being processed. Registered memory, as I previously mentioned, has a register chip that controls the flow of data between the memory module and the memory controller, which allows for higher density and more efficient use of the memory.
High-Performance 3200MHz Clock Speed
I apologize for the confusion, The HPE P43789-B21 memory module operates at a speed of 2666 MHz, not 3200 MHz. The memory clock speed is measured in Megahertz (MHz) and it represents the rate at which the memory module can transfer data to and from the memory controller. A higher clock speed means that the memory can transfer data more quickly, which can result in improved performance in certain applications. The memory clock speed is determined by the JEDEC standard, which is a set of standards for computer memory.
Improved Performance and Power Efficiency with DDR4 Technology
Yes, that is correct. The HPE P43789-B21 memory module uses DDR4 SDRAM technology, which provides improved performance and power efficiency compared to previous generations of DDR memory.
DDR4 offers several advantages over DDR3, including higher memory bandwidth, lower voltage requirements and improved power efficiency. The lower voltage requirement of DDR4 memory (1.2V compared to 1.5V for DDR3) results in a reduction of power consumption and heat generation. This makes DDR4 memory ideal for use in servers and other high-performance computing applications.
In addition, DDR4 memory also has a higher maximum memory density, which means that more memory can be packed into a smaller space. This allows for more memory to be added to a system without increasing the physical size of the memory modules. Overall, the use of DDR4 technology in the HPE P43789-B21 memory module contributes to improved performance and power efficiency in HPE ProLiant servers.
