More Information on the 64GB Memory

The M321R8GA0BB0-CQK is a 64GB SDRAM (Synchronous Dynamic Random Access Memory) module from Samsung, designed for desktop computer systems. It operates at a frequency of 4800MHz and has a PC5-38400 specification, making it a high-performance DDR5 memory option for demanding computing tasks. With its large capacity and fast performance, the M321R8GA0BB0-CQK is an ideal choice for gamers, content creators, and other users who require a significant amount of memory and fast data processing speeds.

Registered Design

The DDR5 memory module is designed with Registered (RDIMM) technology. Registered memory modules include a register (or buffer) between the memory controller and the DRAM (Dynamic Random Access Memory) modules. This register helps to reduce the electrical load on the memory controller, allowing for the use of more modules per memory channel. Registered memory is often preferred in server environments where large amounts of memory are essential.

Low Voltage Operation: 1.1v

Efficient power consumption is a key consideration in modern computing, especially in data centers and server farms where power efficiency directly impacts operational costs. The M321R8GA0BB0-CQK operates at a low voltage of 1.1 volts, contributing to energy efficiency and reduced power consumption without compromising performance.

CL40 Latency

Cas Latency (CL) is a measure of the delay between the memory controller requesting data and the actual data delivery. The M321R8GA0BB0-CQK DDR5 module has a CL40 latency, indicating a relatively low latency level. Lower latency contributes to quicker data access, benefiting applications that require rapid response times and efficient multitasking.

DDR5 Synchronous Dynamic Random Access Memory (SDRAM)

The M321R8GA0BB0-CQK belongs to the DDR5 Synchronous Dynamic Random Access Memory (SDRAM) category. DDR5 is the latest generation of DDR (Double Data Rate) memory technology, offering improved data transfer rates, higher capacities, and enhanced power efficiency compared to its predecessors. Synchronous operation ensures that data is transferred at specific intervals, optimizing overall system performance.

288-Pin RDIMM Form Factor

The memory module adopts the 288-pin RDIMM form factor. The number of pins on a memory module is crucial for proper connectivity and data transfer between the module and the memory controller. The 288-pin design is standard for DDR5 memory modules and ensures compatibility with DDR5-enabled motherboards and server
