Overview of the 840759-791 HPE 64 GB 2666 MHz Pc4-21300 DDR4 SDRAM Ecc Reg Ram Memory Module

The 840759-791 HPE 64 GB 2666 MHz Pc4-21300 DDR4 SDRAM Ecc Reg Ram Memory Module is a high-performance memory module designed for use in HPE servers and workstations. It has a capacity of 64 GB and operates at a speed of 2666 MHz, making it suitable for demanding applications such as data analytics, virtualization, and high-performance computing. The module uses DDR4 SDRAM technology, which offers faster data transfer rates, increased memory density, and improved power efficiency compared to DDR3. Additionally, the module supports Error Correction Code (ECC) which helps to detect and correct memory errors, providing an added layer of data protection. And it is in Registered or Buffered Form which allows for greater control of memory timings, allowing for improved performance in certain applications. This memory module is a 288-pin DIMM, and it is compatible with HPE servers and workstations that support DDR4 memory.

Voltage and Power Consumption of the Memory Module

The 840759-791 HPE 64 GB 2666 MHz Pc4-21300 DDR4 SDRAM Ecc Reg Ram Memory Module typically operates at a voltage of 1.2V. This is lower than the 1.5V required by DDR3 memory, which helps to reduce power consumption and improve energy efficiency. Lower voltage also generates less heat which results in longer life of the module. However, actual power consumption will depend on the specific usage scenario, as well as the number of modules installed in the system. Typically, the more memory modules installed, the higher the overall power consumption will be. However, the power consumption of this memory module is considered to be low, making it suitable for use in servers and workstations that require high performance and energy efficiency.

Form Factor and Pin Configuration of the Memory Module

A memory module, also known as a RAM (Random Access Memory) module, is a printed circuit board that contains one or more memory chips. The form factor of a memory module refers to its physical size and layout, including the number and arrangement of connector pins.

The most common form factor for memory modules is DIMM (Dual In-line Memory Module), which is used for desktop and laptop computers. DIMMs have a rectangular shape with a set of connector pins on each side, making a total of 168 or 240 pins. There are also other types of form factors such as SODIMM (Small Outline DIMM) for laptops and SO-DIMM (Small Outline Dual In-line Memory Module) for embedded systems and other small form factor devices.

The pin configuration of a memory module refers to the specific arrangement of the connector pins on the module. Different types of memory modules, such as DDR, DDR2, DDR3, and DDR4, have different pin configurations. The pin configuration is important because it determines how the module will fit into the memory slot on the motherboard, and whether it is compatible with the computer's memory controller.

It is important to ensure that the memory module's form factor and pin configuration match the specifications of the computer's motherboard before installing it.
