Description
Product Information
The HP 408854-B21 is a type of computer memory designed for use in Proliant servers. This memory kit includes two 4GB memory modules, providing a total of 8GB of storage capacity. It operates on DDR2 SDRAM technology and has a clock speed of 667MHz. This memory kit is manufactured by HP, a leading computer hardware manufacturer. In this article, we will take a closer look at the technical details of this memory kit.
Memory Specifications
Capacity: The HP 408854-B21 memory kit has a total storage capacity of 8GB. This is a significant amount of memory and can support multiple applications running simultaneously on the server.
Memory Type: The HP 408854-B21 memory kit uses DDR2 SDRAM technology. DDR2 SDRAM is the second generation of Double Data Rate Synchronous Dynamic Random Access Memory (DDR SDRAM). This technology offers significant improvements over its predecessor DDR SDRAM, including higher transfer rates, lower power consumption, and improved performance.
Memory Form Factor: This memory kit has a DIMM form factor. DIMM stands for Dual In-line Memory Module. DIMMs have separate electrical contacts on each side of the module, allowing for more memory modules to be installed on a single motherboard.
Memory Speed: The HP 408854-B21 memory kit has a clock speed of 667MHz. The clock speed of a memory module determines how fast data can be read and written to the memory. A higher clock speed means that data can be transferred faster, which results in improved system performance.
Memory Latency: The HP 408854-B21 memory kit has a CAS latency of 5. CAS latency is the delay between the time a memory controller requests data from memory and when the data is actually available. A lower CAS latency means that the memory module can respond to requests faster, resulting in improved system performance.
Memory Rank: The HP 408854-B21 memory kit is a dual-rank memory kit. Memory rank refers to the number of separate memory banks on a memory module. A single-rank memory module has one memory bank, while a dual-rank memory module has two memory banks. Dual-rank memory modules offer slightly better performance than single-rank memory modules, but they are typically more expensive.
Memory Error Correction: The HP 408854-B21 memory kit uses Error Correcting Code (ECC) technology. ECC is a type of memory technology that can detect and correct errors that occur during data storage and retrieval. This technology is particularly useful in server environments, where data integrity is critical.
Compatibility
The HP 408854-B21 memory kit is designed for use with the Proliant server series. It is compatible with a wide range of Proliant servers, including the Proliant BL20p G4, Proliant BL460c G5, and Proliant DL360 G5. It is important to note that this memory kit is not compatible with other server series or desktop computers.
Installation
Installing the HP 408854-B21 memory kit is a straightforward process. First, ensure that the server is powered off and unplugged from the power source. Locate the memory module slots on the server’s motherboard. The number and location of memory module slots may vary depending on the server model. Gently insert the memory modules into the slots, making sure that the modules are properly aligned with the slots. Press down firmly on the memory modules until they click into place. Finally, power on the server and check the BIOS settings to ensure that the memory kit is recognized.
In summary, the HP 408854-B21 is a high-quality memory kit designed for use in Proliant servers. This memory kit provides a significant amount of storage capacity and offers excellent performance and reliability. The use of
