Description
Product Specifications
The 46C7577 is a memory module used in servers. It is a 16GB 2x8gb DDR2 FBDIMM module made by IBM. This article will explain in detail what these specifications mean and how they affect server performance.
Memory Modules
Memory modules are electronic components that store data temporarily in a computer. They are also known as RAM (Random Access Memory) and are an essential component of any computer system. Memory modules come in different shapes and sizes, but the most common form factor is the DIMM (Dual In-line Memory Module).
DDR2
DDR2 is a type of RAM that was introduced in 2003. It is an improvement over DDR (Double Data Rate) RAM and offers faster data transfer rates. DDR2 RAM has a maximum speed of 800 MHz and a voltage of 1.8V. DDR2 RAM is also backward compatible with DDR RAM, meaning that DDR2 RAM can be used in systems designed for DDR RAM.
Fully Buffered DIMM (FBDIMM)
FBDIMM is a memory technology that was introduced in 2006. It is an improvement over the traditional DIMM design and is used in server systems. FBDIMM modules have a memory controller chip on the module itself, which helps to reduce the load on the memory controller of the server.
Registered DIMM (RDIMM)
RDIMM is a type of DIMM that includes a register between the memory controller and the DRAM chips. The register helps to reduce the load on the memory controller by buffering the signals between the memory controller and the DRAM chips. RDIMMs are used in servers to reduce the load on the memory controller and improve the performance of the system.
ECC
ECC (Error Correction Code) is a type of memory technology that is used in servers. ECC memory is designed to detect and correct errors that occur during data transfer. This helps to ensure that data is stored correctly and is not corrupted during the transfer process. ECC memory is essential in server systems, as it helps to prevent data corruption and improve the reliability of the system.
CL5
CL5 is a timing specification that is used in DDR2 RAM. It represents the number of clock cycles that it takes for the RAM to respond to a request from the system. A lower CL number indicates better performance, as it means that the RAM can respond to requests more quickly. CL5 RAM has a latency of 12.5ns, which is relatively fast for DDR2 RAM.
667MHz
667MHz is the clock speed of the 46C7577 memory module. The clock speed represents the number of times per second that the RAM can transfer data. A higher clock speed indicates better performance, as it means that the RAM can transfer data more quickly.
16GB 2x8GB
The 46C7577 memory module has a total capacity of 16GB. This is the amount of data that the RAM can store at any given time. The memory module is made up of 2x8GB modules, which means that there are two 8GB modules on the memory module.
Server Memory
Server memory is designed to handle the demands of server systems. Servers require large amounts of memory to handle multiple requests simultaneously. They also require memory that is reliable and can handle errors that occur during data transfer. Server memory is often designed with features such as ECC and RDIMMs to ensure that it can handle the demands of the system.
