Registered DDR4 SDRAM 288-pin Ram is a type of memory used in servers and high-performance computing systems. It is designed to provide high-speed data access and improved error correction capabilities. Registered DDR4 SDRAM 288-pin Ram uses a 288-pin Dual In-Line Memory Module (DIMM) form factor and is based on DDR4 SDRAM technology. It offers higher memory capacity and faster speeds compared to its predecessor DDR3 SDRAM technology. The main difference between Registered DDR4 SDRAM and Un-registered DDR4 SDRAM is that, Registered DDR4 SDRAM has a register chip on the module which helps to buffer the control signals between the memory controller and the memory module, whereas Un-registered DDR4 SDRAM does not have a register chip.
Understanding Memory Capacity and Speed
Memory capacity refers to the amount of data that can be stored in a memory module. The 815102-S21 HPE 128GB 2666Mhz memory module has a capacity of 128GB, which means it can store up to 128 gigabytes of data. This is a significant amount of memory and can be useful for large-scale data processing, virtualization, and other memory-intensive applications.
Memory speed, also known as memory frequency, is measured in Megahertz (MHz) or Gigahertz (GHz) and refers to the speed at which the memory can transfer data. The 815102-S21 HPE 128GB 2666Mhz memory module has a speed of 2666 MHz, which means it can transfer data at a rate of 2666 million times per second. This is a relatively fast speed and can provide a significant boost in performance for applications that require high memory bandwidth.
It’s important to note that memory capacity and speed are not the only factors that determine overall memory performance. Other factors such as the memory’s CAS Latency, voltage, and timing parameters also play a role. Additionally, the compatibility with the server’s memory controller and the memory channel organization also impact the performance of memory.
Registered vs Unregistered Memory
Registered memory, also known as buffered memory, is a type of memory that includes a register or buffer between the memory controller and the memory chips. This buffer acts as a communication intermediary and helps to improve the reliability and stability of the memory. The register also allows for more memory chips to be added to the module, increasing the capacity of the memory.
Unregistered memory, also known as unbuffered memory, does not have the buffer or register between the memory controller and the memory chips. This type of memory is less expensive to produce and is often used in consumer-grade systems.
In general, registered memory is considered to be more reliable and stable than unregistered memory, as it is able to handle more memory chips and has better error-correcting capabilities. However, it is also typically more expensive and may not be compatible with certain types of systems.
The 815102-S21 HPE 128GB 2666Mhz is registered memory.
