HP HMT84GL7AMR4C-RD Frequently Asked Questions

What does it mean if memory runs at 1866Mhz?

When memory operates at 1866MHz, it means that the memory module is functioning at a frequency of 1866 million cycles per second. The unit "MHz" represents megahertz, which is equivalent to one million cycles per second. In this case, the memory is capable of completing 1.866 billion cycles within a single second.

The clock speed of memory is a crucial factor that determines its performance, specifically how quickly it can send and receive data. With memory running at 1866MHz, it suggests a moderate speed for data transfer.

It's worth noting that memory performance is influenced by multiple factors, including memory type, timings, and the overall system configuration. While clock speed provides valuable insight into memory capabilities, it's important to consider these other factors in order to gain a comprehensive understanding of the memory's overall performance and effectiveness.

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 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.

"We're a Canadian company who was badly in need of a drive for our server. Wasn't sure how the cross border purchase would go but Scott and his team had us taken care of at a price that couldn't be beaten and with lightning speed and efficiency. We had our drive in just a few days. I would highly recommend this company! Wish there were more out there like them!"
