Product Details of the HPE 846740-001
The 846740-001 is a type of computer memory module. Specifically, it is a 16GB (1X16GB) DDR4 SDRAM module with an ECC registered dual-rank x4 configuration, operating at a speed of 2400MHz. It is designed to be used with HPE Proliant Gen9 servers, which are high-performance, enterprise-level servers used in data centers and other large-scale computing environments. In this article, we will provide an in-depth explanation of what each of these specifications means and how they contribute to the performance of a server.
DDR4 SDRAM
DDR4 SDRAM stands for Double Data Rate 4 Synchronous Dynamic Random Access Memory. It is a type of volatile memory, meaning that its contents are lost when the power is turned off. DDR4 is the fourth generation of DDR memory and is currently the most widely used type of memory in modern computers. It is faster and more energy-efficient than its predecessor, DDR3, and is capable of higher memory densities.
ECC Registered
ECC stands for Error-Correcting Code. ECC memory is a type of memory that includes additional data bits to detect and correct single-bit errors that can occur during data transmission. ECC memory is often used in mission-critical systems where data integrity is of utmost importance, such as in servers and data centers.
Registered memory, also known as buffered memory, is a type of memory module that includes an additional register between the memory controller and the memory chips. This register helps to reduce the electrical load on the memory controller and allows for larger memory configurations. Registered memory is often used in servers and other high-performance computing environments.
Dual Rank X4
The 846740-001 memory module is a dual-rank module. This means that it contains two sets of memory chips, or ranks, that can be accessed independently. Dual-rank modules are typically faster than single-rank modules because they can handle more data in parallel.
The X4 designation refers to the number of memory chips on each rank and the width of each chip's data path. X4 memory chips are 4 bits wide, which means that each chip can store or retrieve 4 bits of data at a time. The wider data path allows for faster data transfers and higher memory bandwidth.
2400MHz
The 846740-001 memory module operates at a speed of 2400MHz. Memory speed, also known as memory frequency, refers to the rate at which the memory module can transfer data. The higher the memory speed, the faster the memory module can transfer data.
Cas-17
CAS stands for Column Address Strobe. It is a timing parameter that determines how many clock cycles it takes for the memory controller to access a specific column of memory. CAS latency, also known as CL, is measured in clock cycles. A lower CAS latency indicates faster memory access times.
The 846740-001 memory module has a CAS latency of 17, which means that it takes 17 clock cycles for the memory controller to access a specific column of memory. This is a relatively low CAS latency and indicates fast memory access times.
288-pin DIMM
The 846740-001 memory module is a 288-pin DIMM, which stands for Dual Inline Memory Module. DIMMs are a type of memory module used in desktop and server computers. The number of pins on a DIMM determines the type of memory module and the type of slot it can be installed in.
Smart Memory
Smart Memory is a term used by HPE to describe their memory modules that include additional features and capabilities beyond standard memory modules. Smart Memory includes features such as advanced error correction, performance tuning, and health monitoring.
