The HP 408855-B21 is a server memory module manufactured by HP. It has a capacity of 16GB and runs at a speed of 667 MHz using PC2-5300 memory specification and CL5 latency. It is a ECC (Error Correction Code) Registered DDR2 SDRAM memory module, and uses 240-pin DIMM form factor.
ECC memory includes extra memory bits that are used to detect and correct errors that occur in the memory, which can help to improve the reliability and stability of the system. ECC memory is typically more expensive than non-ECC memory and also takes up more memory capacity.
Registered memory, also called buffered memory, includes a buffer chip that is used to improve the reliability of the memory module, this can help in systems with many DIMMs or with high memory population. This can help to prevent data corruption and also can help to improve the system stability.
It is important to note that this memory is using DDR2 technology, which is an older memory technology and it is being phased out in favor of newer DDR3 and DDR4. So it might be limited in certain server or system and also could affect the overall performance.
It's important to check the specific compatibility with the server or system that you plan to use this memory module with. The memory architecture of the server, the number of memory slots available, the maximum capacity and the clock speed of the memory should be considered. It's also important to check the server documentation or specifications to ensure the compatibility and the installation instructions.
In summary, the HP 408855-B21 memory module is designed for servers and offers a reliable solution for servers that require ECC memory with a capacity of 16GB and runs at a decent speed of 667 MHz, however it's using an older technology and it might be limited in certain servers and system, also can affect the overall performance. It's important to ensure the compatibility before purchasing and consider the age of the technology and how this will affect the overall performance and limitation of your server.
The performance of the HP 408855-B21 memory module will depend on several factors, such as the overall system configuration, the specific use case, and the workloads of the server.
The 16GB of capacity allows the server to handle larger amounts of data which can help to improve the performance of the system by allowing it to run multiple applications at the same time without running out of memory. Additionally, the memory's speed of 667 MHz can also help to improve the overall system responsiveness and performance.
However, the memory module is using the older DDR2 technology, which has a lower bandwidth and lower speed compared to newer DDR3 and DDR4 memory technology. It could affect the overall performance when running high-performance workloads or with modern server.
It's important to note that the performance of this memory module will depend on the specific use case and the overall system configuration.It's highly recommended to consult the vendor's documentation or specifications to ensure the compatibility, the installation instructions, and how this module will perform in your specific scenario, also check the overall system configuration and workloads, to ensure that the memory is able to meet the requirements.
In summary, The HP 408855-B21 memory module offers a high capacity of 16GB and runs at a decent speed of 667 MHz which can help to improve the performance of the system, however it uses the older DDR2 technology which could limit its performance especially when running high-performance workloads or with modern server. It's important to ensure the compatibility before purchasing and consider the age of the technology and how this will affect the overall performance and limitation of your server.
The HP 408855-B21 memory module is designed to provide a high level of reliability for servers. It's built with ECC (Error Correction Code) which includes extra memory bits that are used to detect and correct errors that occur in the memory. This feature can help to improve the reliability and stability of the system, it can help in preventing data corruption and also can help to improve the system stability.
Additionally, the memory module is also Registered (buffered) memory, includes a buffer chip that is used to improve the reliability of the memory module. This is especially important in systems with many DIMMs or with high memory population. It can help to prevent data corruption and also can help to improve the system stability.

About New Bulk Pack Products
Are you looking for the best PC-5300 modules for your server or PC? Allhdd.com is your one-stop-shop for modules from top brands on the market. We have a wide range of memory kits you can choose from. Browse through our website for the best PC2-5300 modules for all your needs.
Double Data Rate (DDR) stands for Synchronous Dynamic Random-Access Memory (SDRAM). It is the typical type of memory that serves as RAM for almost all modern-day processors.
The DDR2 SDRAM (Double Data Rate 2 SDRAM) is the upgrade to DDR SDRAM. It comes with a four-bit pre-fetch buffer and runs its external data bus at double the DDR SDRAM speed to facilitate a faster performance.
Buying DDR2 SDRAM from allhdd.com is pretty much straightforward if you know the front-bus of your system.
There are a handful of features to look out for when choosing a RAM. Suppose you wanted to decide between RAMs of varying clock speeds. In that case, the RAM with a greater clock speed is better. However, when choosing between RAMs of identical clock speeds, the RAM with lower CAS latency will perform faster. Latency is a measure of how long it takes to collect data from memory. The higher this figure, the greater the latency.
The DDR2 PC2-5300 memory is generally regarded as DDR2-667. Its design and unique features work efficiently with systems featuring a 333MHz front-side bus, rendering a data transfer rate of 667MT/s.
The PC2 5300 RAM has a module bandwidth of 5300MB/s. This bandwidth is the highest amount of data the PC2 5300 transfers every second.
Depending on your preference and budget, there are various PC2-5300 memory kits and sizes you can buy here on allhdd.com. These include 4GB, 8GB, 16GB, 64GB, 32GB, and 128GB memory kits. All units are brand new and available at pocket-friendly prices.
Factors to consider before buying the PC2 modules
Your system's RAM is the single most crucial feature for a flawless performance. Hence, picking one requires some attention to certain factors.
You should know the frequency at which your server or computer motherboard operates. It is catastrophic to mount a memory with a lower frequency than the motherboard's minimum frequency. You risk damaging both RAM and your motherboard. Here are the typical speeds for DDR2 SDRAM modules:
PC2-3200 (DDR2-400 at 3200Mbps throughput)
PC2-8500 (DDR2-1066), and
- RAM Size
Depending on your hardware, the modern-day memory module size ranges from 4GB to 128GB. If your system performs a lot of multitasking daily, you'll need a bigger RAM size. You can buy all memory kits ranging from 4GB, 8GB, 16GB, 64GB, 32GB, and 128GB, 256GB, 512GB, 1TB, and more here on allhdd.com.
- DDR Generation
Motherboards that are built to support the newer generation DDR will not work with older generations. Be sure to figure out what works for your PC. A DDR2 memory module will not work on a motherboard that features a DDR3 DIMM slot. The same thing applies to other memory modules and DIMM slots.
- Number of Channels
Dual channels are the most preferred choice when it comes to the channel number. Say your PC needs 16GB; in that case, you can take a two 8GB memory kit in dual channel mode.
