Details Information

The HP 8GB 1600MHz PC3-12800 DDR3 SDRAM CL11 ECC Registered Ram is a specific model of computer memory that is designed to meet the requirements of servers and high-performance workstations. The key details of this memory module are as follows:

  • Capacity: 8GB (gigabytes) - This is the amount of memory that is included on the module. 8GB is a relatively large amount of memory, which can help to improve the performance of a computer by allowing it to handle more programs and data at the same time.
  • Speed: 1600 MHz (megahertz) - This is the clock speed of the memory, which is the rate at which the memory can send and receive data. The higher the clock speed, the faster the memory can operate. 1600 MHz is a relatively fast clock speed for memory of this type.
  • PC3-12800 - This is the data transfer rate of the memory, which is the amount of data that can be transferred to and from the memory in a given amount of time. The higher the data transfer rate, the faster the memory can operate. PC3-12800 is equivalent to 12,800MB/s and is relatively high data transfer rate
  • DDR3 SDRAM - This is the type of memory technology used in the module. DDR3 (double data rate type 3) is a type of synchronous dynamic random-access memory that is commonly used in computers. SDRAM stands for Synchronous Dynamic Random Access Memory, it is a type of DRAM that can synchronize itself with the clock speed of the computer, allowing for faster data transfer rates.
  • CAS Latency: CL11 - CAS latency is the delay time between the computer's sending a column address to the memory and the memory's sending out the corresponding data. The lower the CAS latency, the faster the memory can access data. CL11 is relatively low CAS latency for this type of memory.
  • ECC: Error Correction Code - This is a feature that helps detect and correct errors in the memory, which can improve the reliability of the memory and prevent data corruption. ECC can provide a higher level of protection against data loss and corruption than non-ECC memory
  • Registered - A type of memory that uses a register between the memory controller and the DRAM to buffer and stabilize the data signals. it add an extra latency layer but it provide lower error rate and it can support more RAM on a motherboard. This feature is useful for servers and high-performance workstations that need to handle large amounts of data and require a high level of memory stability and reliability.

HP Server Ram

The HP 8GB 1600MHz PC3-12800 DDR3 SDRAM CL11 ECC Registered Ram (Part number: 647899-B21) is a type of server memory that is manufactured by HP. It has a capacity of 8GB and runs at a speed of 1600 MHz. It uses DDR3 SDRAM technology and has a CAS latency of 11. The ECC (Error Correcting Code) feature 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.

Smart Memory

Smart Memory refers to a type of memory that has been optimized for use in HP servers and workstations. It is typically tested and validated for compatibility with HP systems, and is also designed to meet HP's specific performance and reliability requirements.

The HP 8GB 1600MHz PC3-12800 CL11 ECC Registered DDR3 SDRAM Ram (Part number: 647899-B21) is a type of Smart Memory specifically designed for use in HP servers and other high-end computing systems. It has a capacity of 8GB and runs at a speed of 1600 MHz, which can help improve the overall performance and efficiency of the system.

The CL11 (CAS Latency) value indicates that it takes 11 clock cycles for the memory module to respond to a command, which can affect memory access time. And 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.

Smart Memory, like this one, will be HP branded and validated for compatibility, ensuring optimal performance for your specific HP system.

About New Bulk Pack Products

New Bulk Pack products come with clamshell boxes and do not have any manufacturer warranty. Many times manufacturers disassemble whole units to use parts or pulled from a new system. Typically, this product doesn't come with software or instructions unless indicated and no Manufacturer’s genuine warranty. You can take note these are not brand new products.

PC3-12800 ram

The PC3-12800 RAM operates at a conventional voltage of 1.35V. It is generally regarded as a low power consumption memory module. One of its huge benefits remains that it is backward compatible with 1.5V. Depending on the capacity you require, we have a wide range of PC3-12800 240-Pin DDR3 SDRAM 1.35V SODIMM here on allhdd.com.

I/O bus clock

The input/output bus clock of the PC3 12800 memory is 800MHz. It is usually half the data bus rate.

Considerations Before Investing in a Memory Module

When it comes to memory, there are a handful of factors to consider before making any purchase decision. The more RAM available to the system's CPU, the easier its job becomes, enabling a faster computer. However, suppose you do not have a sufficient amount of RAM. In that case, your CPU has to work much harder during data transfer, severely reducing the computer's performance. In addition to the amount of RAM, here are other factors to consider before buying a RAM.

  • Memory Type

It is no longer news that just any memory module will not be compatible with your computer. Every computer comes with specific memory requirements depending on the motherboard's configuration and its particular memory type. It is needless to say that DDR3 memory will only work with motherboards with a DDR3 configuration. You should check your computer and its motherboard before picking a RAM for it.

  • DIMM Slots and Matched Pairs

The memory slots are dual inline memory connectors, regarded as DIMM slots, which stipulates that memory be installed as exact pairs in the right places. Should you be buying two memory sticks, ensure they are of the same frequencies. Paring two memory speeds of varying frequencies could lead to upgrade problems and low performance.
