Description
Product Details
The Supermicro MEM-DR412L-CL02-LR26 is a type of computer memory module. It is a DDR4 SDRAM LRDIMM with a capacity of 128GB. In this article, we will explain the various technical terms associated with this memory module and what they mean.
Memory Module Basics
A memory module is a small circuit board that contains memory chips. The purpose of a memory module is to provide temporary storage for data that the computer is currently using. When the computer needs to access data, it retrieves it from the memory module. The faster the memory module can retrieve data, the faster the computer can operate.
DDR4 SDRAM
DDR4 SDRAM stands for Double Data Rate Fourth Generation Synchronous Dynamic Random Access Memory. DDR4 is the latest type of memory technology and offers faster data transfer rates and lower power consumption than its predecessor DDR3. SDRAM stands for Synchronous Dynamic Random Access Memory. Synchronous means that the memory operates in synchronization with the system clock. Dynamic means that the memory needs to be refreshed regularly to maintain its contents.
LRDIMM
LRDIMM stands for Load-Reduced Dual In-Line Memory Module. LRDIMMs are a type of memory module that can reduce the load on the memory controller. This is achieved by using a buffer between the memory chips and the memory controller. The buffer allows the memory controller to communicate with the memory chips more efficiently, resulting in higher memory capacities and better performance.
ECC Registered
ECC stands for Error-Correcting Code. ECC memory is designed to detect and correct errors that occur during data transmission. ECC memory is essential in server environments, where data accuracy is critical. Registered memory, also known as buffered memory, is designed to reduce the electrical load on the memory controller. This is achieved by placing a register between the memory module and the memory controller. The register acts as a buffer, allowing the memory controller to communicate with the memory module more efficiently.
2666MHz PC4-21300
2666MHz is the frequency at which the memory module operates. The frequency of a memory module refers to the number of clock cycles per second that the memory module can perform. In general, the higher the frequency, the faster the memory module can transfer data. PC4-21300 is a term used to describe the bandwidth of the memory module. The bandwidth is the amount of data that can be transferred per second. PC4-21300 means that the memory module has a bandwidth of 21.3GB/s.
CL19
CL19 is a timing specification that refers to the latency of the memory module. Latency refers to the delay between when the memory module is accessed and when the data is available. The lower the latency, the faster the memory module can retrieve data. CL19 means that the latency of the memory module is 19 clock cycles.
8Rx4
8Rx4 refers to the organization of the memory chips on the memory module. The “R” in 8Rx4 stands for rank. A rank is a group of memory chips that are accessed simultaneously. The “x4” in 8Rx4 stands for the number of banks on each rank. In this case, there are four banks per rank. The “8” in 8Rx4 stands for the number of ranks on the memory module. This means that there are eight groups of memory chips that are accessed simultaneously.
1.2V
1.2V is the voltage required to operate the memory module. The voltage required for memory modules has decreased over time, resulting in lower power consumption and less heat generated by the memory module.
