Key Features of Hynix 64GB DDR5 SDRAM

The Hynix 64GB DDR5 SDRAM (HMCG94MEBRA121N) is a high-performance computer memory module that offers several key features to enhance your computing experience.

  • Capacity: This memory module provides 64GB of memory capacity, which is more than enough for demanding applications such as gaming, video editing, and heavy multitasking.
  • Speed: The HMCG94MEBRA121N operates at a speed of 4800MHz, which is faster than most DDR4 memory modules and provides a noticeable improvement in performance.
  • DDR5 Technology: The DDR5 technology used in this memory module is the latest standard in computer memory and provides higher speeds and improved energy efficiency compared to DDR4.
  • 288-Pin Connector: The 288-pin connector is designed to provide a high-bandwidth connection between the memory module and the motherboard, which helps to optimize performance.
  • CL40 Latency Timings: The CL40 latency timings are an important factor in determining the overall performance of a memory module, and this module has lower latency timings compared to DDR4, providing faster data access times.
  • Error Correction: The HMCG94MEBRA121N supports ECC (Error Correction Code) Reg, which helps to detect and correct errors in data transmission, ensuring the integrity of your data.
  • Compatibility: This memory module is compatible with the PC5-38400 system bus, making it suitable for use in a wide range of computers and servers.

Memory Capacity and Speed

The Hynix 64GB DDR5 SDRAM (HMCG94MEBRA121N) has two important specifications that determine its performance: memory capacity and speed.

  • Memory Capacity: This memory module has a capacity of 64GB, which is a significant amount of memory for a single module. This large memory capacity is ideal for demanding applications such as gaming, video editing, and heavy multitasking, where a large amount of memory is required to prevent slowdowns and system crashes.
  • Speed: The HMCG94MEBRA121N operates at a speed of 4800MHz, which is a significant increase over the speed of DDR4 memory modules. The faster memory speed means that data can be accessed and processed more quickly, leading to improved performance in a wide range of applications.

It's important to note that while the HMCG94MEBRA121N offers a large memory capacity and fast memory speed, it is only one component of a computer system. Other components such as the processor, graphics card, and storage drive can also impact overall system performance.

Error Correction and Registers

The Hynix 64GB DDR5 SDRAM (HMCG94MEBRA121N) features two important technologies related to error correction and registers: ECC (Error Correction Code) Reg and 288-pin connector.

  • ECC (Error Correction Code) Reg: ECC is a technology that helps to detect and correct errors in data transmission, ensuring the integrity of your data. ECC is especially important in applications where data accuracy is critical, such as scientific simulations, financial modeling, and enterprise servers. The ECC Reg support in the HMCG94MEBRA121N provides an extra layer of protection for your data, helping to prevent errors and ensure data reliability.
  • 288-Pin Connector: The 288-pin connector is a type of interface that connects the memory module to the motherboard. The high-bandwidth connection provided by the 288-pin connector helps to optimize performance and reduce the chances of data transmission errors. The 288-pin connector is designed to provide a secure and reliable connection, ensuring that the memory module operates at its full potential.

Together, the ECC Reg support and 288-pin connector provide important features for improving data reliability and performance in the Hynix 64GB DDR5 SDRAM (HMCG94MEBRA121N). These features make the memory module well-suited for demanding applications where accuracy and reliability are important.

About New Bulk Pack Products

New Bulk Pack products come with clamshell boxes and do not have any manufacturer warranty. Many times manufacturers disassemble whole units to use parts or pulled from a new system. Typically, this product doesn't come with software or instructions unless indicated and no Manufacturer’s genuine warranty. You can take note these are not brand new products.

RAM is probably the most important organ of your PC or server. Because if we define a processor as the heart of a computer system, RAM is its brain.

RAM in a server system is one of the components that are directly responsible for the performance of the system. Officially it is called RAM (Rapid Storage Device), which can temporarily store the output, input, and intermediate data of the operating system and programs. RAM is a power-dependent device because data storage in such a system requires a constant power supply, or if there is no power supply, all memory cells are cleared.

The main characteristic of high-quality RAM is its speed in the first place. At the same time, installing 2 or more memory modules in a computer system must necessarily choose modules that will work at the same speed, because the system chooses the slowest speed from the available memory modules.

Focusing on the tasks assigned to the server device, you can choose the memory by volume. It will be sufficient to buy RAM up to 2 GB to solve every day not complicated tasks, and when upgrading the computer system and for more complex purposes - the memory capacity of at least 4 GB will suffice. There are two most popular RAM types on the market today, namely DDR2 and DDR3. And at the same time, it is important to remember that they are absolutely incompatible with each other.

We recommend installing DDR (double-data-rate) memory modules of modern 3rd generation (namely DDR3). This type of memory has higher clock frequencies (up to 2,400 MHz), and lower power consumption (30-40% lower compared to DDR2), and, consequently, reduced heat emission.

What other characteristics of RAM you should pay attention to when choosing it:

  • Form factor, i.e. the type of design of the memory module itself;

This is essentially the memory board construction. It includes the memory module size, number, and location of contacts. Keep in mind that different form factors are incompatible with each other.

  • Bus frequency and data transfer rate.

Bus bandwidth and frequency depend on each other. When choosing the required frequency, you need to rely on the capabilities offered by the system. We recommend choosing a frequency that matches the one supported by your CPU and motherboard.

  • The amount of memory that has already been mentioned;

A bigger RAM is required when running administrative software like spam prevention or antivirus checking, which takes up a lot of space. Choosing the right memory RAM is highly prioritized to ensure the computer's 100% performance. Many options of RAM are available online with different storage space for every server's needs.

  • Timings.

That is latency or time delays of your RAM. The bandwidth, and therefore the speed of the whole system, will directly depend on them.

What is the Manufacturer/Brand Warranty?

In general, a manufacturer's warranty service/support is a written guarantee to the buyer of a product. Its terms assure the replacement or repair of the product, if necessary, within a specified period after the purchase (2-5 years depending on the brand/manufacturer). It is typically included in the price of the product. Products are brand new and sealed and the original manufacturer box is complete with the Manufacturer's genuine warranty. For most of the brand new/retail products that come with the manual and box, exceptions may apply (i.e., Cisco, Juniper Networks).

For the server parts (i.e., Dell, HPE) to get Full coverage of the warranty server must have a full 3- 5 years warranty. However, ALLHDD.COM will cover the warranty duration if any Manufacturer doesn't support the advertised warranty and there is no refund for those.
