The HP 504351-S21 is a 8GB (2 x 4GB) memory module designed for use in HP ProLiant servers and workstations. It operates at a speed of 800 MHz and has a memory type of PC2-6400 ECC Registered DDR2 SDRAM. ECC stands for "Error Correcting Code," which means that the memory includes extra bits for detecting and correcting errors that may occur during data transfer. This can help to improve the reliability and stability of the system. The memory module is also Registered, which means that it includes a register between the DRAM chips and the system's memory controller to buffer and manage data transfer. This can help to improve performance in systems with multiple memory modules. The memory has a CAS latency of 6, which refers to the delay time between the moment a memory controller sends a read command and the moment the data is available on the module's output pins. A lower CAS latency value can improve the performance of the system.
The performance of the HP 504351-S21 memory module will depend on several factors, including the speed at which it operates (800 MHz in this case), the memory type (PC2-6400 ECC Registered DDR2 SDRAM), and the CAS latency (CL6).
The speed of the memory, measured in megahertz (MHz), determines how quickly the module can transfer data. A higher speed can improve the overall performance of the system.
The memory type, such as DDR2 SDRAM or DDR3 SDRAM, determines the technology used by the memory module. Different memory types can have different performance characteristics and may be better suited to different types of systems.
CAS latency, or CL, refers to the delay time between the moment a memory controller sends a read command and the moment the data is available on the module's output pins. A lower CL value can improve the performance of the system by reducing the amount of time it takes for the system to access data from the memory.
The HP 504351-S21 memory module includes ECC (Error Correcting Code) technology, which can help to improve its reliability and stability. ECC memory includes extra bits that can be used to detect and correct errors that may occur during data transfer. This can help to prevent data corruption and reduce the likelihood of system crashes or other issues caused by faulty memory.
The memory module is also Registered, which means that it includes a register between the DRAM chips and the system's memory controller to buffer and manage data transfer. This can help to improve performance in systems with multiple memory modules and may also contribute to the reliability of the system.
Overall, the HP 504351-S21 memory module should offer good reliability for a variety of tasks and applications. It is important to note, however, that no memory module is completely immune to errors or failure, and it is always a good idea to have a backup plan in place to protect against data loss.

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.
