Type - PC4-17000

The designation PC4-17000 specifies the RAM's type and maximum data transfer rate. In simpler terms, it indicates that the RAM module can handle a data transfer rate of up to 17000 megabytes per second. This aligns with industry standards for efficient and high-performance computing.

ECC (Error-Correcting Code)

The inclusion of ECC, or Error-Correcting Code, is a crucial feature of the HPE 790109-001. ECC allows the RAM to detect and correct data errors in real-time, enhancing system stability and reliability. This is especially important in professional and enterprise environments where data accuracy is paramount.


The term "Registered" signifies that this RAM module features registered signal processing. This technology adds a buffer to the memory module, resulting in increased stability and reliability, particularly in high-density memory configurations. Registered RAM is commonly used in servers and workstations where precision is critical.

The 790109-001 memory module is ECC registered. ECC stands for Error-Correcting Code, which is a type of memory technology that can detect and correct errors in data stored in memory. ECC memory is used in servers and workstations that require high levels of data reliability and uptime. The registered aspect of the memory module means that it has a register that acts as a buffer between the memory module and the memory controller. This buffer helps to improve stability and performance in systems with multiple memory modules.

Technology - DDR4 SDRAM

The HPE 790109-001 operates on DDR4 SDRAM technology, representing the latest evolution in RAM. DDR4 offers improvements in efficiency and performance compared to its predecessors. It allows for higher data transfer rates, lower power consumption, and increased overall system responsiveness.

The 790109-001 memory module is a 1Rx4 DIMM. DIMM stands for Dual In-Line Memory Module, which is a type of memory module used in computers. The "1Rx4" part of the designation indicates that the memory module has one rank and four memory chips on each rank. This configuration allows for high memory density in a single module, making it ideal for use in servers and workstations that require high memory capacity.

Pin Configuration - 288-Pin

The 288-pin configuration refers to the physical design of the RAM module and how it connects to the motherboard. In this case, the module is equipped with 288 pins, ensuring a secure and efficient connection for seamless data transfer.

The 790109-001 memory module has 288 pins. The number of pins on a memory module determines how it connects to the motherboard. The 288-pin configuration is a standard for DDR4 SDRAM memory modules and is compatible with a wide range of motherboards and systems.

Check the motherboard manufacturer's website for BIOS/UEFI updates. Updating the system firmware can sometimes resolve compatibility or performance issues.

Reseat the RAM

If you suspect a connection issue, power off your computer, disconnect the power source, and reseat the RAM module, ensuring a secure fit in the slot.

Memory Module Type

The 790109-001 memory module is a type of DDR4 SDRAM. SDRAM stands for Synchronous Dynamic Random-Access Memory, which is a type of memory used in computers for temporary storage of data. DDR4 stands for Double Data Rate 4, which is the fourth generation of DDR SDRAM technology. DDR4 SDRAM offers significant improvements over its predecessor, DDR3, including higher data transfer rates, lower power consumption, and improved reliability.

Memory Latency

The 790109-001 memory module has a CAS latency of 15. Memory latency is a measure of the delay between when a memory request is made and when the requested data is available. A lower CAS latency indicates a shorter delay, which can improve application performance. The CAS latency of 15 for the 790109-001 memory module is relatively low, making it ideal for use in servers and workstations that require low latency and fast data access.
