HP 501536-001 Frequently Asked Questions

What does it mean if memory runs at 1333Mhz?

When memory runs at 1333MHz, it means that the memory module operates at a frequency of 1333 million cycles per second. The unit "MHz" represents one million cycles per second. In practical terms, the memory can complete 1.333 billion cycles within a single second.

Memory running at 1333MHz is commonly associated with DDR3 SDRAM (Double Data Rate 3 Synchronous Dynamic Random-Access Memory) technology. DDR3 memory, including the 1333MHz variant, was introduced in 2007 as a successor to DDR2 memory.

The 1333MHz memory speed was part of the DDR3 specification, which was developed by JEDEC (Joint Electron Device Engineering Council), an organization responsible for establishing industry standards for semiconductor devices. DDR3 memory brought significant improvements over DDR2, including higher data transfer rates, increased bandwidth, and lower power consumption.

The release of 1333MHz memory marked a notable advancement in memory technology at the time, offering improved performance and efficiency compared to its predecessor. It became a popular choice for mainstream computer systems and found widespread adoption in various applications.

It's important to consider that memory technology has continued to progress since the release of 1333MHz memory. DDR4 memory, for instance, has since been introduced, providing even higher clock speeds and enhanced performance. However, 1333MHz memory may still be found in systems that are compatible with DDR3 memory or in specialized applications that do not require the higher speeds offered by newer memory technologies.

When evaluating memory capabilities, it's crucial to consider compatibility with the system's specifications and requirements. Additionally, factors such as memory type, timings, and the overall system configuration should be taken into account to accurately assess the memory's capabilities and performance.

What does it mean if memory is ECC?

ECC, which stands for Error-Correcting Code, refers to a type of memory module that incorporates advanced error-checking and error-correction capabilities. ECC memory goes beyond standard non-ECC memory by providing additional measures to ensure data integrity.

The primary purpose of ECC memory is to detect and correct certain types of data errors that may occur during the operation of a computer system. It achieves this by adding extra bits, known as parity or checksum bits, to each memory word stored in the module.

These extra bits enable the ECC mechanism to identify and automatically correct single-bit errors. If a single bit is flipped or corrupted, the ECC memory can detect the error and rectify it, preventing potential data corruption and maintaining accurate information storage.

ECC memory is particularly prevalent in critical computing systems, such as servers and workstations, as well as in environments where data integrity is paramount, such as scientific or financial applications. By providing an additional layer of error detection and correction, ECC memory significantly reduces the risk of undetected errors that could lead to system crashes, data corruption, or inaccurate calculations.

It's important to note that the utilization of ECC memory requires support from both the motherboard and the memory controller in the system. Not all systems or consumer-grade motherboards offer compatibility with ECC memory, so it's crucial to verify the specifications and requirements before incorporating ECC memory modules into a specific system.

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

DIMM stands for Dual In-Line Memory Module. It is a type of memory module used in computers to provide random access memory (RAM). DIMMs are rectangular circuit boards that contain multiple memory chips and have electrical contacts on both sides. They are designed to be inserted into a computer's motherboard, connecting to the memory slots.


DIMM memory modules were first released in the late 1980s and gained widespread adoption in the 1990s. They replaced the older SIMM (Single In-Line Memory Module) technology, which had a single row of electrical contacts. DIMMs offered several important advancements over SIMMs:


  1. Increased capacity: DIMMs allowed for a greater number of memory chips to be installed on a single module, thus increasing the overall capacity of RAM that a computer could support. This enabled computers to handle more demanding applications and perform tasks more efficiently.

  2. Improved data transfer rates: DIMMs supported higher data transfer rates compared to SIMMs. This increase in speed allowed for faster communication between the RAM and the computer's processor, resulting in improved overall system performance.

  3. Enhanced error correction and reliability: DIMM modules introduced error-correcting code (ECC) capabilities, which helped detect and correct memory errors. This was crucial for critical computing environments, such as servers, where data integrity and reliability are paramount.

  4. Compatibility and scalability: DIMMs offered greater flexibility in terms of compatibility and expandability. They could be used across a wide range of computer systems, allowing for easy upgrades and replacement of memory modules as technology advanced.


Overall, the introduction of DIMM technology represented a significant advancement in computer memory. It provided higher capacity, increased speed, improved reliability, and greater compatibility, all of which contributed to enhanced system performance and efficiency. DIMMs have continued to evolve over the years, with various iterations and advancements, such as DDR (Double Data Rate) and its subsequent generations, further improving memory capabilities in modern computer systems.

What does it mean if memory has a speed of 1333MHz?

In the context of server RAM (Random Access Memory), "1333 MHz" refers to the memory's clock speed, which is a measure of how quickly the memory can process data. The clock speed is measured in megahertz (MHz) and indicates the number of cycles the memory can complete in one second. In this case, 1333 MHz means that the memory module can complete 1.333 billion cycles per second.

Memory modules with a clock speed of 1333 MHz were released around the mid-2000s, particularly in the years 2007-2009. This marked a significant advancement in technology compared to earlier memory modules that had lower clock speeds.

The importance of this advancement can be understood in the context of improving overall system performance, especially in servers. Here's why the increase in memory clock speed was significant:

  1. Faster Data Processing: The higher clock speed allowed data to be transferred to and from the memory at a faster rate. This meant that applications and the operating system could access data stored in memory more quickly, leading to overall improved performance.

  2. Reduced Latency: Latency refers to the time delay between making a request for data and receiving the data. Higher clock speeds helped reduce memory access latency, leading to quicker response times and smoother multitasking.

  3. Better Multitasking: Servers often run multiple tasks simultaneously. With faster memory, the server could handle more tasks efficiently without experiencing significant slowdowns due to memory bottlenecks.

  4. Improved Bandwidth: The increased clock speed also led to higher memory bandwidth, which refers to the amount of data that can be transferred between the memory and other components (like the CPU) in a given amount of time. Higher bandwidth is crucial for data-intensive applications.

  5. Enhanced Server Performance: In server environments, performance is essential for serving clients, processing data, and running applications. Faster memory contributed to better overall server performance and responsiveness.

Support for Advanced Applications: As technology advanced, applications and software became more resource-intensive. Higher clock speed memory allowed servers to keep up with these demands, ensuring smooth operation of resource-intensive tasks.

It's important to note that memory speed is just one factor among several that influence overall system performance. The CPU, storage, and other components also play vital roles. While 1333 MHz memory was a notable advancement, subsequent generations of memory modules with even higher clock speeds have been developed, further improving server performance.
