Features and Benefits of 838085-B21

I apologize, but I do not have enough information about the product number 838085-B21 to provide an explanation of its features and benefits. The product number 838085-B21 is not specific and could refer to multiple products.

ECC (Error Correcting Code) DDR4 SDRAM is a type of RAM that is commonly used in servers and workstations because it is able to detect and correct errors in data as it is being accessed. This feature is particularly important in these types of machines because they are often used for critical tasks and data integrity is crucial.

288-pin R-DIMM (Registered Dual In-line Memory Module) is a type of memory module that is commonly used in servers and workstations. R-DIMMs have a register chip on the module that helps control the flow of data to and from the memory, improving performance and stability in systems with multiple memory modules.

Without more information about the specific product, it's impossible to determine other features and benefits that the product may have. I suggest you check the HPE website or contact HPE support for more information about the specific product.

Memory Type and Speed 838085-B21 HPE 64GB 2666Mhz Pc4-21300

The HPE 838085-B21 is a 64GB memory module that operates at a speed of 2666Mhz. This means that the module can transfer data at a rate of 2666 million cycles per second. The faster the memory speed, the better the performance of the system.

The memory type is PC4-21300, which is a type of DDR4 (double data rate 4) SDRAM (Synchronous Dynamic Random Access Memory). DDR4 is the latest generation of memory technology and offers several advantages over its predecessor, DDR3. It has a higher memory bandwidth, which means that it can transfer data faster. It also has a lower voltage requirement (1.2V compared to 1.5V for DDR3) which results in lower power consumption and heat generation.

The PC4-21300 is a specific type of DDR4 SDRAM that is able to transfer data at a rate of 17000 MB/s (Mega bytes per second) which is faster than its previous version DDR3. This type of memory is commonly used in servers, workstations and high-end PCs because of its high performance and energy efficiency.
