Description
The Dell 32GB AA783422 is a Registered Dual Rank In-Line Memory Module (RDIMM) designed for use in Dell servers. It features a capacity of 32GB, DDR4 SDRAM technology, and a speed of 3200 MHz (PC4-25600).
RDIMM vs. UDIMM: RDIMMs are specifically designed for servers and offer improved signal integrity and stability compared to UDIMMs (Unbuffered DIMMs) commonly used in desktops. They also include a register chip that buffers data transfers between the memory module and the memory controller, reducing the load on the CPU and improving overall system performance.
Dual Rank: A dual-rank memory module contains two sets of memory chips, effectively doubling the data transfer rate compared to a single-rank module. This can be beneficial for applications that require high memory bandwidth, such as virtualization, databases, and high-performance computing.
ECC Memory: Error-Correcting Code (ECC) memory adds an extra bit to each data byte, allowing for the detection and correction of single-bit errors. This is crucial for mission-critical applications where data integrity is paramount.
Important Considerations:
Ensure compatibility with your specific Dell server model before purchasing. Dell’s website offers compatibility checkers to verify memory compatibility.
Mixing memory modules with different speeds or capacities may not be optimal and can affect system performance.
Installing memory modules requires following the server’s manual to avoid damaging components.
