The 497767R-B21 is an 8GB DDR2 SDRAM memory module manufactured by HP. It is designed to be used in servers that require high-performance memory modules to handle heavy workloads. This memory module is registered, which means it uses a buffer to store data temporarily before it is sent to the processor. This buffer allows for better stability and reliability, making it an ideal choice for servers.
PC2-6400 800MHz DDR2 SDRAM
The 497767R-B21 memory module is a DDR2 SDRAM, which stands for Double Data Rate 2 Synchronous Dynamic Random Access Memory. DDR2 is an older type of memory that was commonly used in servers until DDR3 and DDR4 became more popular. The PC2-6400 rating indicates that this memory module can operate at a maximum frequency of 800MHz, which means it can transfer data at a rate of up to 6.4GB/s.
Timing refers to the delay between different operations within the memory module. CL6 timing means that the memory module has a CAS latency of 6 clock cycles. CAS latency is the delay between when the memory controller requests data and when the data is available. Lower CAS latencies indicate faster access times, which can improve the overall performance of the server.
Registered memory, also known as buffered memory, is a type of memory that uses a buffer to temporarily store data before it is sent to the processor. This buffer helps to improve stability and reliability by reducing the load on the memory controller. The buffer also allows for more memory modules to be used in a server without causing stability issues. Registered memory is more expensive than unbuffered memory, but it is essential for servers that require high performance and stability.
The 497767R-B21 memory module has 240 pins and uses a dual in-line memory module (DIMM) form factor. DIMMs are the most common type of memory module used in servers and desktop computers. The number of pins on a DIMM determines the type of memory it is and the speed at which it can operate.
In Summary, the 497767R-B21 8GB PC2-6400 800MHz DDR2 SDRAM CL6 Memory Module Registered Proliant 240-Pin DIMM for Server made by HP is a high-performance memory module designed for use in servers that require stable and reliable memory. Its registered design and CL6 timing make it an ideal choice for servers that need to handle heavy workloads. Its 240-pin DIMM form factor makes it compatible with a range of HP Proliant servers. Before purchasing this memory module, it is essential to ensure that the server is compatible with it to prevent compatibility issues.

About New Bulk Pack Products
Do you have a computer with a motherboard configured for the DDR2 memory modules? Chances are you want to get the best out of your system in terms of performance. If all of these catch your fancy, then you are just at the right spot for top-quality PC2 modules with unbeatable performance. Allhdd.com is home to some of the best PC2-6400 modules, compatible with some of the well-known brands. Our collection includes the 4GB and the 8GB variants.
The PC2 6400 Memory Module
Improving your system's performance can be achieved by simply adding more memory to your PC. The PC2 6400 RAM series presents the ideal memory modules for stability and speed. The PC2-6400 (240-Pin DDR2 800 SDRAM) can conveniently move your system into the fast lane. The DDR2 PC2-6400 (generally regarded as the DDR2-800) module is a DDR2 memory device for use in motherboards featuring a front-side bus of 400MHz. The number "6400" indicates the maximum amount of data the memory can transfer per second which is 6400 Megabytes, and is the module's bandwidth. DDR2-800 is backward-compatible for DDR2-533 and DDR2-667.
Memory Clock Speed
The PC2-6400 memory chips can work at 800 MHz. It is otherwise referred to as the RAM's memory clock speed. The RAM's speed does not change how fast the CPU can go, even when hyper-threaded or overclocked. However, it can slow the CPU down if there is ample space in the RAM or not.
I/O bus clock
The I/O bus clock refers to half the bus transfer speed. The PC2-6400 (DDR2 800) has a bus clock of 400MHz.
Considerations Before Investing in a Memory Module
Even though the 240-Pin DDR3 SDRAM is an excellent memory module for your system, it remains that there are a few things to keep in mind before you click the "Add to Cart" button. Not all memory is best suited for your system; there is a little homework to do before investing in RAM. Here are some factors to consider.
First up is the RAM form factor. There are two main types of RAM form factors: the DIMM form factor for desktop computers and the SO-DIMM for laptops. Thus, you should buy a SO-DIMM type of RAM if you have a laptop PC and vice versa.
This is crucial because earlier generation DDR memory is not compatible with motherboards built to work with newer generation DDR memory and the other way round. DIMM slots in motherboards are explicitly designed to support a particular memory generation. Consequently, you can't install DDR2 memory in a motherboard featuring DDR3 DIMM slots.
Amount of RAM
Power users will need more RAM to handle highly-demanding applications than conventional system users. This is needless to say that you should consider the system's workload before choosing a RAM. The right amount of RAM on the computer facilitates better performance and the capacity to sustain various applications.
