HYNIX HMAA8GL7MMR4N-TF Frequently Asked Questions

What does it mean if memory runs at 1.2v?

If memory runs at 1.2V, it means that the memory module operates at a voltage of 1.2 volts. The voltage specification is an important factor in determining the power requirements and compatibility of the memory with the system.

Memory modules running at 1.2V are commonly associated with DDR4 (Double Data Rate 4) memory technology. DDR4 was introduced as the successor to DDR3 and brought significant improvements in performance, energy efficiency, and data transfer rates.

The release of 1.2V memory modules, specifically DDR4 modules, was driven by major memory manufacturers, including Samsung, Micron, SK Hynix, and others. These manufacturers recognized the need for higher memory capacities, increased speed, and improved power efficiency to meet the evolving demands of computing systems.

The shift to 1.2V voltage in DDR4 modules was motivated by the industry's focus on energy efficiency and power savings. By operating at a lower voltage, DDR4 memory modules offered reduced power consumption and heat generation compared to their predecessors.

The lower voltage of 1.2V in DDR4 modules was chosen as a balance between performance and power efficiency. It allowed for improved data transfer rates and higher memory densities while minimizing power requirements and contributing to energy-conscious computing.

DDR4 memory modules running at 1.2V voltage became the standard for mainstream computer systems, including desktops, laptops, servers, and other computing platforms. They provided higher performance, increased memory capacities, and improved power efficiency compared to previous memory technologies.

It's important to note that compatibility with the system's memory controller and motherboard is essential when using 1.2V memory modules. The system's hardware should be designed to support and operate at this voltage to ensure proper functionality.

DDR4 memory, operating at 1.2V, revolutionized the memory landscape by offering improved efficiency and performance for a wide range of computing applications. Its introduction brought significant advancements to memory technology, catering to the growing demands of modern computing systems for faster, more power-efficient memory solutions.

What does it mean if memory has a chipset of 4Rx4?

When referring to server RAM, the term "4Rx4" pertains to the organization and configuration of the memory modules. Let's break it down further:

  • "4R" signifies that the memory module consists of four ranks. A rank represents a logical grouping of memory chips on the module, allowing for independent access and improved memory performance.

  • The "x4" indicates the arrangement of memory chips within each rank. Specifically, it signifies a 4-bit configuration, meaning that each chip can store 4 bits of data.

This particular memory configuration, featuring four ranks and a 4-bit organization within each rank, provides several important advancements in technology. It enables higher memory capacity, allowing for greater data storage, and enhances data transfer rates compared to previous configurations. This results in the simultaneous access of larger amounts of data and improved memory bandwidth.

The introduction of memory modules with the 4Rx4 configuration can be traced back to the mid-2000s. Since then, this technology has continued to evolve and find broader application.

The significance of the 4Rx4 configuration lies in its key benefits:

  1. Increased Memory Capacity: By incorporating four ranks, more memory chips can be accommodated on a single module, facilitating higher memory capacities. This is particularly crucial for server environments that handle resource-intensive workloads.

  2. Enhanced Performance: The 4Rx4 configuration improves memory performance through the utilization of multiple ranks and the resulting parallelism. This enables faster data access and transfer rates, minimizing bottlenecks and elevating overall system performance.

  3. Improved Fault Tolerance: With multiple ranks, memory modules become more resilient. In the event of a fault occurring in one rank, the remaining ranks continue to function, reducing the impact on system stability and reliability.

In summary, the 4Rx4 memory configuration represents a significant technological advancement in server RAM. It offers expanded memory capacities, improved performance, and increased fault tolerance, all of which are essential for demanding server applications and workloads.

What does it mean if memory is DDR4?

DDR4, which stands for Double Data Rate 4th Generation, is a type of computer memory technology utilized in servers, desktops, and laptops. Its introduction occurred in 2014 as the successor to DDR3 memory.

DDR4 brought forth several crucial technological advancements compared to its predecessor:

  1. Enhanced Data Transfer Rates: DDR4 offered increased data transfer rates, facilitating faster communication between the memory and the processor. This improvement resulted in heightened system performance and responsiveness.

  2. Higher Memory Density: DDR4 introduced higher memory density, enabling more memory to be packed onto a single module. This expanded the maximum RAM capacity that could be installed in a system, accommodating larger memory requirements.

  3. Reduced Power Consumption: DDR4 memory modules operated at lower voltage levels compared to DDR3. This reduction in voltage led to decreased power consumption, thereby improving energy efficiency and prolonging battery life, especially in mobile devices.

  4. Improved Error Correction: DDR4 implemented superior error correction capabilities, enhancing the reliability and stability of the memory subsystem. This advancement was particularly critical for servers and systems that necessitate stringent data integrity.

  5. Future-Proofing: DDR4 laid the groundwork for future memory technologies and advancements. It offered scalability and compatibility with evolving processor architectures, ensuring seamless system upgrades and adaptability to future applications and technologies.

In summary, DDR4 represented a significant leap in memory technology, delivering faster speeds, larger capacities, improved power efficiency, and heightened reliability compared to its predecessors. These advancements contributed to enhanced overall system performance and addressed the escalating demands of modern computing applications.

What does it mean if memory is LRDIMM?

When memory is referred to as LRDIMM, it signifies that it belongs to the category of Load-Reduced Dual In-Line Memory Modules. LRDIMM is a specialized type of memory module that offers certain advantages over standard memory modules.

LRDIMM technology employs a memory buffer or an advanced memory buffer (AMB) chip to reduce the electrical load on the memory bus. This buffer acts as an intermediary between the memory chips and the memory controller, helping to enhance memory performance and capacity.

The main advantage of LRDIMMs is their ability to support larger memory capacities compared to standard memory modules. By reducing the electrical load on the memory controller, LRDIMMs enable the system to accommodate more memory modules per channel, thereby increasing the overall memory capacity.

LRDIMMs are commonly used in scenarios that demand extensive memory capabilities, such as enterprise-level servers, data centers, and high-performance computing environments. Their ability to support larger memory capacities is particularly beneficial for applications that involve data-intensive tasks, virtualization, and complex computations.

It's important to note that LRDIMMs require compatible hardware support. The motherboard and memory controller must specifically support LRDIMM technology. Therefore, it is crucial to verify the system's compatibility and consult the system documentation or manufacturer's guidelines before utilizing LRDIMMs.
