Product Details

The 6A9781929 32GB DDR4 memory module is a product made by Dell, designed to cater to the needs of server users. The module is built to offer high-performance computing with a focus on reliability and security. In this article, we will explain the key features of the module, including its capacity, clock speed, latency, rank, and voltage.


The 6A9781929 32GB DDR4 memory module has a capacity of 32GB, which is a significant amount of memory for server use. The module can store and retrieve large amounts of data quickly, making it suitable for use in data centers, cloud computing, and other applications that require high-performance computing.

Clock Speed

The module has a clock speed of 2666MHz, which means that it can perform 2.66 billion cycles per second. A higher clock speed means that the module can process data faster, which is essential for applications that require real-time data processing, such as financial trading or gaming.


The 6A9781929 32GB DDR4 memory module has a CL19 latency, which refers to the time it takes for the module to respond to a request from the CPU. The lower the latency, the faster the module can respond to the request. A CL19 latency is relatively low, which means that the module can perform fast data transfers.


The module has a dual rank, which means that it has two sets of memory chips. A dual rank module is faster than a single rank module, as it can perform two memory accesses at the same time. This feature makes the 6A9781929 32GB DDR4 memory module suitable for applications that require high-speed data transfers.


The module has a voltage of 1.2V, which is a relatively low voltage. A lower voltage means that the module consumes less power, which reduces the heat generated by the module. This feature is essential in server applications, where multiple modules are used, and heat generation can become a significant problem.

Registered DIMM

The 6A9781929 32GB DDR4 memory module is a registered DIMM. Registered DIMMs are designed to provide a higher level of reliability and security than unbuffered DIMMs. Registered DIMMs have an additional register that buffers the address and command signals, reducing the electrical load on the memory controller. This feature makes registered DIMMs more stable and reliable, especially in applications that require large amounts of memory.

288-Pin R-DIMM

The 6A9781929 32GB DDR4 memory module has 288 pins, which is standard for registered DIMMs. The module's pins are arranged in a specific way to ensure that they can only fit into a compatible slot on the motherboard. The R-DIMM designation means that the module is a registered DIMM, as opposed to an unbuffered DIMM.

In Summary, the 6A9781929 32GB DDR4 memory module is a high-performance memory module designed for server use. It has a capacity of 32GB, a clock speed of 2666MHz, a CL19 latency, a dual rank, and a voltage of 1.2V. The module is a registered DIMM with 288 pins, which ensures compatibility with the motherboard. These features make the module suitable for applications that require high-speed data transfers, large amounts of memory, and high levels of reliability and security.
