Description
Product Specifications
49Y1445 is a type of memory module made by IBM, designed specifically for use in servers. It is a registered ECC DDR3 SDRAM RDIMM module, with a capacity of 4GB and a speed of 1333MHz. This memory module has a CL9 latency and uses Dual Rank X4 memory technology. In this article, we will delve deeper into what these terms mean and how they affect the performance of the server.
ECC Registered Memory
ECC stands for Error Correction Code, which is a type of memory technology that can detect and correct errors that occur during data transmission. This is especially important in server environments, where data integrity is critical. ECC memory uses additional bits to check for errors, which helps to ensure that the data stored in memory is accurate and reliable.
Registered memory, on the other hand, is a type of memory module that uses a buffer to store data. This buffer helps to reduce the electrical load on the memory controller, which can improve system stability and reliability. Registered memory is also better suited for systems with a large amount of memory, as it can help to prevent data corruption and improve overall performance.
DDR3 SDRAM
DDR3 SDRAM stands for Double Data Rate 3 Synchronous Dynamic Random-Access Memory. It is a type of memory technology that is commonly used in servers, as well as desktop and laptop computers. DDR3 SDRAM is designed to transfer data twice as fast as its predecessor, DDR2 SDRAM. It is also more power-efficient, which helps to reduce the overall energy consumption of the server.
1333MHz PC3-10600
The speed of memory is measured in megahertz (MHz), which refers to the number of cycles per second that the memory can perform. The 49Y1445 memory module has a speed of 1333MHz, which means that it can perform 1.3 billion cycles per second. This is also known as PC3-10600, which is a standard rating for DDR3 SDRAM modules.
CL9 Latency
Latency is the amount of time that it takes for the memory to respond to a request from the system. The 49Y1445 memory module has a CL9 latency, which means that it takes nine clock cycles to respond to a request. Lower latency is generally better, as it can improve the overall performance of the server.
LP DDR3 SDRAM RDIMM
LP DDR3 SDRAM RDIMM stands for Low Power Double Data Rate 3 Synchronous Dynamic Random-Access Memory Registered Dual In-Line Memory Module. This is a mouthful, but it essentially means that the memory module is designed to consume less power than other types of memory, which can help to reduce the overall energy consumption of the server. LP DDR3 SDRAM RDIMMs are also more stable and reliable than other types of memory, making them ideal for use in server environments.
Dual Rank X4 Memory
Dual Rank X4 memory is a type of memory technology that uses two sets of memory chips to store data. This helps to improve the overall performance of the memory module, as it allows for more data to be transferred at once. X4 memory refers to the number of bits that can be accessed simultaneously, with X4 indicating that four bits can be accessed at once.
In Summary, the 49Y1445 memory module is a registered ECC DDR3 SDRAM RDIMM module designed for use in servers. It has a capacity of 4GB, a speed of 1333MHz, a CL9 latency, and uses Dual Rank X4 memory technology. LP DDR3 SDRAM RDIMMs are known for their low power consumption and high stability, making them an ideal choice for use in server environments.
