Memory Type and Speed

The AA153023 Dell 16GB 2666MHz PC4 21300 CL19 ECC Registered DDR4 SDRAM 288 pin RAM is a type of computer memory that is used to store data and instructions that the computer processor can access quickly.

Memory Type:

  • DDR4 SDRAM: This RAM is a type of synchronous dynamic random-access memory (SDRAM) and is the fourth generation of DDR memory technology. DDR4 SDRAM offers faster speeds, lower power consumption, and increased reliability compared to its predecessor DDR3.
  • ECC Registered: This refers to the error-correcting code (ECC) feature, which is designed to detect and correct errors that occur during data storage and retrieval. The registered feature helps to improve memory stability and performance by reducing electrical loading.

Memory Speed:

  • 2666MHz: This is the clock speed at which the memory operates, and it indicates how many cycles per second the RAM can perform. In this case, the RAM can perform 2666 million cycles per second.
  • PC4 21300: This refers to the memory's peak bandwidth and is calculated by multiplying the clock speed (2666MHz) by the number of bits transferred per clock cycle (64 bits). In this case, the peak bandwidth is 21300 megabytes per second.
  • CL19: This refers to the CAS latency of the memory and is the number of clock cycles it takes for the memory controller to access the requested data. In this case, the CAS latency is 19 clock cycles.

Capacity and Speed

The AA153023 Dell RAM module has a capacity of 16GB and a speed of 2666MHz. Let's break down what this means:


The capacity of the RAM module refers to the amount of data that it can store and access. In this case, the capacity of the module is 16GB, which means it can store and access up to 16 gigabytes of data.


The speed of the RAM module refers to how quickly it can transfer data. In this case, the speed is 2666MHz, which means it can transfer data at a rate of 2.66 billion cycles per second.

Impact System Performance

AA153023 is a type of memory module manufactured by Dell. It has a capacity of 16GB and a speed of 2666MHz. It uses the DDR4 SDRAM technology and has ECC (Error-Correcting Code) Registered functionality. The module has 288 pins and operates at a latency of CL19.

The impact of this type of memory module on system performance can vary depending on the system it is being used in and the workload being performed. However, in general, here are some ways that the specifications of AA153023 could impact system performance:

  • Capacity: The 16GB capacity of this module means that it can store more data in memory at once. This can help improve performance for memory-intensive applications such as video editing, rendering, or database management.
  • Speed: The 2666MHz speed of this module means that it can transfer data between the memory and the CPU faster. This can help improve performance for tasks that require frequent access to memory, such as gaming or virtualization.
  • DDR4 SDRAM: DDR4 is the latest generation of SDRAM technology, offering faster speeds and lower power consumption than previous generations. This can help improve overall system performance.
  • ECC Registered: ECC (Error-Correcting Code) memory is designed to detect and correct errors that can occur when data is stored or retrieved from memory. This can help improve system stability and reduce the likelihood of crashes or data corruption.
  • 288 pins: The number of pins on a memory module determines how it connects to the motherboard. 288 pins is a common configuration for DDR4 memory modules and is compatible with most modern motherboards.
  • CL19 latency: Latency is a measure of the time it takes for the memory to respond to a request from the CPU. CL19 latency is relatively high, which means that there may be a slight delay when accessing data from memory. However, the impact on overall system performance is likely to be minimal.
