Samsung M471A2K43CB1-CPB Frequently Asked Questions

What does it mean if memory has a latency of CL15?

In the context of server RAM (Random Access Memory), "CL15" refers to the CAS latency of the memory module. CAS latency (Column Address Strobe latency) is a measure of the time it takes for the memory module to respond to a read command. It is often represented as a number followed by "CL" (e.g., CL15).

CAS latency is one of the timings that defines the performance of a RAM module. Lower CAS latency values indicate faster responsiveness and better performance. CL15 signifies that it takes 15 clock cycles for the memory module to respond to a read command. In general, lower CAS latency is preferred because it results in faster data retrieval from memory.

Memory modules with lower CAS latency values, such as CL15, were released as part of advancements in DDR4 (Double Data Rate 4) RAM technology. DDR4 memory was introduced as the successor to DDR3, and it brought several improvements:

  1. Higher Data Rates: DDR4 memory offered higher data transfer rates compared to its predecessor, DDR3. This meant that more data could be read from or written to the memory in a given amount of time, improving overall system performance.

  2. Higher Density: DDR4 allowed for higher memory module densities, meaning that more memory could be packed into a single module. This was particularly important for servers and workstations that require large amounts of memory to handle complex tasks and applications.

  3. Improved Energy Efficiency: DDR4 memory modules operated at lower voltage levels compared to DDR3, leading to improved energy efficiency and reduced power consumption. This was important for both performance and environmental reasons, as data centers and server farms strive to minimize their energy consumption.

  4. Increased Bandwidth: DDR4's architecture allowed for increased memory bandwidth, which improved the speed at which data could be transferred between the memory and the processor. This was particularly beneficial for memory-intensive applications.

  5. Better Reliability: DDR4 memory also introduced features to enhance data integrity and reliability, making it more suitable for critical server environments.

The introduction of memory modules with lower CAS latency, such as CL15, further contributed to the overall performance improvements brought about by DDR4 technology. Lower CAS latency helps reduce the delay in accessing data from memory, resulting in quicker response times for applications and improved overall system responsiveness.

What does it mean if memory is "Non-ECC"?

If memory is specified as "non-ECC," it means that it is a type of memory module that does not incorporate Error-Correcting Code (ECC) capabilities.

Non-ECC memory, also known as unbuffered or non-registered memory, lacks the additional error-checking and error-correction mechanisms found in ECC memory modules. This type of memory is more commonly used in consumer-grade systems, such as home computers, laptops, and gaming PCs.

Non-ECC memory operates without the extra parity or checksum bits present in ECC memory. As a result, it does not have the ability to detect or correct certain types of data errors that may occur during memory operations.

While non-ECC memory is more affordable and widely available, it is generally considered sufficient for most consumer computing needs where data integrity is not critical. Non-ECC memory still provides reliable data storage and retrieval, making it suitable for tasks such as general computing, web browsing, and gaming.

It's important to note that when using non-ECC memory, the overall system stability and data integrity may rely more heavily on other components, such as the reliability of the motherboard, power supply, and other error-checking mechanisms implemented at the software or system level.

What does it mean if memory has a form factor of SODIMM?

If memory has a form factor of SODIMM, it means that it is designed according to the Small Outline Dual In-Line Memory Module standard. SODIMM is a compact form factor primarily used in laptops, mini PCs, and other small form factor computing devices.

SODIMM modules are characterized by their smaller physical size compared to regular DIMM modules. They feature a dual in-line pin configuration similar to DIMM modules but with reduced dimensions. The smaller size of SODIMM modules allows them to fit into systems with space constraints while providing memory expansion capabilities.

SODIMM memory modules were introduced in the early 1990s as a variation of the DIMM standard. The exact release and specific manufacturer responsible for the introduction of SODIMM modules may vary. However, it is generally recognized that the standard was developed and adopted by major computer memory manufacturers to meet the demands of the emerging laptop and portable computing market.

SODIMM modules became popular due to their compatibility with smaller computing devices where space is limited, such as laptops and mini PCs. They offered a convenient and standardized memory form factor for these systems, allowing for easy installation and upgrading of memory.

Over the years, SODIMM modules have evolved to support various memory technologies, including SDRAM, DDR, DDR2, DDR3, DDR4, and DDR5, catering to the advancing requirements of portable computing devices.

Today, SODIMM modules continue to be widely used in laptops, mini PCs, compact desktops, and embedded systems. They provide the flexibility to increase memory capacity and enhance system performance in space-constrained environments, offering a practical solution for memory expansion in portable computing devices.

What does it mean if memory has a speed of 2133MHz?

The term "2133 MHz" refers to the clock speed or frequency at which a particular type of RAM (Random Access Memory) operates. RAM frequency, often measured in megahertz (MHz) or gigahertz (GHz), indicates how many cycles the RAM module can complete in one second. In simple terms, it measures how fast data can be read from or written to the RAM.

The 2133 MHz speed rating you mentioned likely corresponds to DDR4 RAM, which was released in 2014. DDR4 stands for "Double Data Rate 4," and it's a type of RAM that succeeded DDR3. The 2133 MHz speed is one of the initial and most common speeds at which DDR4 RAM was introduced.

The move from DDR3 to DDR4 RAM brought several important advancements in technology:

  1. Higher Data Rates: DDR4 RAM provided higher data transfer rates compared to its predecessor, DDR3. This allowed for faster access to data stored in memory, leading to improved overall system performance, especially in tasks that involve frequent data access.

  2. Increased Bandwidth: DDR4 offered increased memory bandwidth, enabling more data to be transferred between the RAM and the CPU in a given amount of time. This was particularly beneficial for applications that required large amounts of data to be moved quickly, such as video editing, 3D rendering, and scientific simulations.

  3. Lower Voltage: DDR4 RAM operates at lower voltage levels compared to DDR3 RAM. This reduction in voltage helped in decreasing power consumption and heat generation, contributing to more energy-efficient and cooler-running systems.

  4. Higher Capacity Support: DDR4 introduced the capability to manufacture higher-capacity memory modules. This was crucial for accommodating the growing demands of modern software and applications that require larger memory capacities to run smoothly.

  5. Improved Error Correction: DDR4 incorporated improved error correction mechanisms, which enhanced the reliability of memory operations. This was especially important in mission-critical applications where data integrity is crucial.

Overall, the introduction of DDR4 RAM, including modules running at 2133 MHz and higher frequencies, marked a significant advancement in memory technology. It helped bridge the gap between the increasing demands of software and the need for faster, more efficient data access, contributing to better overall system performance and user experience.
