The HP 16GB 667MHz PC2-5300 ECC Registered DDR2 SDRAM DIMM (240-pin) RAM (Part number: 408855-S21) is a type of server memory that is manufactured by HP. It has a capacity of 16GB and runs at a speed of 667 MHz. It uses DDR2 SDRAM technology and has an ECC (Error Correcting Code) feature which allows for detection and correction of errors in the memory which can help prevent data corruption. It is also registered, which means it is designed for use in servers and other high-performance systems that require increased data integrity.
It is a 240-pin DIMM(Dual In-line Memory Module), which is the standard form factor for DDR2 memory, used in most of the servers.
The PC2-5300 designation indicates it is compliant with JEDEC standard, and this memory runs at 667 MHz, and it is commonly used with Intel Xeon processors and other high-performance systems that require increased data integrity.
Please note that this part number is for DDR2 memory, which is an older technology and may not be compatible with the latest servers. It is always recommended to check the compatibility with the HP server model by visiting the HP website and searching for the part number "408855-S21" on the server's product page or in the compatibility matrix.
The HP 16GB 2x8GB 667MHz PC2-5300 CL5 ECC Registered Dual Rank DDR2 SDRAM DIMM (240-pin) Memory Module for servers (Part number: 408855-S21) is a type of high-performance memory manufactured by HP, specifically designed for use in servers and other high-end computing systems. It has a total capacity of 16GB, made of two 8GB memory modules, and runs at a speed of 667 MHz, which can help improve the overall performance and efficiency of the system.
The CL5 (CAS Latency) value indicates that it takes 5 clock cycles for the memory module to respond to a command, which can affect memory access time. The ECC (Error Correcting Code) feature allows for detection and correction of errors in the memory, which can help prevent data corruption, and being registered memory, it has a register between the RAM and memory controller, which allows the memory controller to perform operations on the RAM in a more orderly and controlled fashion, which can also improve efficiency.
It is a 240-pin DIMM (Dual In-line Memory Module), which is the standard form factor for DDR2 memory and commonly used with Intel Xeon processors and other high-performance systems that require increased data integrity. The PC2-5300 designation indicates it is compliant with JEDEC standard.

HP validate this memory module for compatibility with specific HP systems, ensuring optimal performance and reliability.
To ensure compatibility, you should check that the memory module is compatible with your specific HP server model, and that it is also compatible with the existing memory configuration in your server. It is also important to make sure that the server's firmware and BIOS are up-to-date and compatible with the memory module.
You can check the compatibility of this memory with the HP server model by visiting the HP website and searching for the part number "408855-S21" on the server's product page or in the compatibility matrix. Additionally, you can also check the server's documentation, such as the User Guide or Maintenance and Service Guide, for information on compatible memory options.
It is worth mentioning that, this memory module using the DDR2 technology, which is an older technology, and the server must be compatible with DDR2 memory to ensure a successful installation. It is always recommended to use the HP's website for validating the compatibility for a better result.

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.
