The HP 495604-B21 is a memory module designed for use with HP ProLiant servers. It has a capacity of 64GB, which is a large amount of memory. It runs at a speed of 667 MHz (PC2-5300) and uses DDR2 SDRAM technology, which is the second generation of DDR memory and is typically used in servers and high-end PCs. The module also has ECC (Error Correcting Code) support, which can detect and correct certain types of data corruption, and follows the standard 240-pin form factor.
DDR2 memory is slower and less power-efficient than its successor DDR3, but still its widely used in several older server models and some specific purposes like industrial control systems, infrastructure equipment, and scientific computers.
ECC memory is typically used in servers and other mission-critical systems to ensure data integrity and prevent system crashes caused by memory errors.
The large amount of memory in the HP 495604-B21 can help to improve the performance of memory-intensive applications, such as large databases, virtualization software, and video editing software. It can also help to reduce the amount of time the system spends waiting for data to be retrieved from storage and improve system responsiveness.
It is important to check the compatibility with the specific server model and its specifications before installing it, and also be aware that using a higher-capacity memory module than the system is designed to support may not improve performance, as the additional memory may not be used by the system.
In summary, The HP 495604-B21 is a high-capacity memory module that is designed for use with HP ProLiant servers and provides ECC support for data integrity, but it is important to check for compatibility before installation and ensure that the additional memory will be used by the system to see performance improvements.
HP Server Memory
The HP 495604-B21 is a high-capacity memory module that is designed for use with HP ProLiant servers. It has a capacity of 64GB, which is a very large amount of memory, and runs at a speed of 667 MHz (PC2-5300). The module uses DDR2 SDRAM technology, which is the second generation of DDR memory and is typically used in servers and high-end PCs, although it is considered slower than its successor DDR3. It also has ECC (Error Correcting Code) support, which can detect and correct certain types of data corruption, making it more suitable for use in mission-critical applications where data integrity is essential.
Adding more memory to a server can improve its overall performance, particularly when running memory-intensive applications such as virtualization software, large databases, and video editing software. The high capacity memory allows the server to store more data in memory, reducing the need to access data stored on slower storage devices, which can improve system responsiveness and application performance.
ECC memory is typically used in servers and other mission-critical systems to ensure data integrity and prevent system crashes caused by memory errors. ECC memory can detect and correct certain types of data corruption, which is important for environments that require high data reliability.
When it comes to compatibility, it is important to check the specific server model and its documentation (such as the user manual or the technical specifications on the HP website) to ensure that the HP 495604-B21 memory module is compatible with the server. It is also important to ensure that the server supports DDR2 memory and has the correct memory slot configuration and also supports ECC memory.
Please be aware that using a higher-capacity memory module than the system is designed to support may not improve performance, as the additional memory may not be used by the system. Updating the firmware and bios of the server might be also necessary, prior to installing the memory module.
The HP 495604-B21 is a module of 64GB of DDR2 SDRAM (Double Data Rate 2 Synchronous Dynamic Random Access Memory), that is intended to be used as server or workstation memory.DDR2 SDRAM is a type of memory that is commonly used in servers and workstations, and it is designed to work in conjunction with a system's central processing unit (CPU) to provide fast, efficient access to data. This particular module is composed of 18 memory chips, and each chip is 4GB of memory.The 495604-B21 module has a clock speed of 667 MHz, which means that it can transfer data at a rate of 667 million times per second. This is considered a relatively fast clock speed for DDR2 memory, and it can help to ensure that the system has sufficient memory bandwidth to handle demanding workloads.The module is also ECC (Error Correction Code) memory, which means that it includes extra memory bits that are used to detect and correct memory errors. ECC memory is typically used in servers and other high-end systems where data integrity is critical, and it helps to prevent data corruption caused by memory errors.The module is also 240-pin module, which means that it is designed to plug into a 240-pin memory slot on a server or workstation motherboard. It has a standard height and should be compatible with most server and workstations that are designed to use DDR2 memory.

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.
