Memory Timings and Latency
Memory Timings and Latency refer to the specific characteristics of a memory module that affect the speed and performance of the memory.
The P18447-B21 HPE 128GB 2666Mhz Pc4-21300 Cl19 Ecc Reg 8rx4 DDR4 SDRAM 288-Pin Ram has memory timings of CL19, which is the CAS (Column Address Strobe) Latency value. This value measures the time (in clock cycles) it takes for the memory controller to access a particular column of data in the memory module after a row has been selected. The lower the CAS Latency value, the faster the memory.
It also has a memory latency of 8rx4, which refers to the number of ranks (8) and the number of banks (4) in the memory module. The memory rank refers to the independent memory modules that are located in the same memory package. The more ranks in a module, the more memory channels can be accessed at the same time, which can increase the memory speed. The memory bank refers to the independent memory modules that are located in the same memory package. The more banks in a module, the more memory channels can be accessed at the same time, which can increase the memory speed.
It's important to note that memory timings and latency are dependent on the system's memory controller and the memory architecture, so the actual memory timings and latency may vary. It's recommended to consult with the vendor or the system manufacturer for more information on the memory timings and latency and how they affect the performance of the memory.
ECC and Registration features
Error Correction Code (ECC) is a type of memory technology that is used to detect and correct errors that may occur in data stored in a computer's memory. It works by adding extra bits, called parity bits, to the data stored in memory. These parity bits are used to detect and correct errors that may occur when the data is read from memory. ECC memory is typically used in mission-critical applications, such as servers and high-performance computing systems, where data integrity is of the utmost importance.
Registered memory (also called buffered memory) is a type of memory that uses a small amount of additional hardware, called a register, to buffer the data as it is sent to and from the memory module. This helps to improve the stability of the memory and can also help to increase performance in certain situations. Registered memory is typically used in servers and high-end workstations, where stability and performance are critical.
HPE 128GB 2666Mhz Pc4-21300 Cl19 Ecc Reg 8rx4 DDR4 SDRAM 288-Pin Ram is a type of memory module that features both ECC and Registered memory technology. It is designed for use in server and high-performance computing systems where data integrity and stability are of the utmost importance.
Installation and Configuration
Installing and configuring ECC and Registered memory can vary depending on the specific system and motherboard you are using. However, generally, the installation process is similar to installing standard memory.
Here are some general steps to install ECC and Registered memory:
- Power off your system and unplug all cables.
- Open the computer's case to access the memory slots.
- Locate the memory slots on the motherboard and check the memory configuration. Make sure the memory modules you are installing are compatible with your system.
- Carefully align the memory module with the memory slot and gently press down until the module snaps into place.
- Repeat the process for any additional memory modules.
- Close the computer's case and reconnect all cables.
- Power on the system and enter the BIOS or UEFI setup.
- Locate the memory configuration settings and ensure that the system recognizes the new memory.
- Configure the memory settings according to the system requirements.
- Save the settings and exit the BIOS or UEFI setup.
It's always recommended to refer to the system or motherboard's documentation for specific instructions on how to install and configure ECC and Registered memory.
Additionally, you should also be aware of the proper configuration of the memory, as the incorrect configuration can cause system instability and other issues. The most important thing is to follow the instructions of the motherboard manufacturer for the best results.

What is the DDR4 Memory Standard?
The Double Data Rate Fourth Generation Synchronous Dynamic Random-Access Memory, otherwise known as The DDR4 SDRAM, is the latest high-efficiency memory module with 288 pins, released to the public in the second quarter of 2014. The PC4-21300 or DDR4-21300 comes with a mega transfer speed of 21300Mg/s. It flaunts cutting-edge performance and is highly compatible with AMD Ryzen processors and DDR-enabled Intel motherboards.
Memory Clock Speed
The clock speed is the measure of the number of cycles the system's CPU executes per second. In the case of the PC4 21300 memory module, it is 21,300MB/s. You'd want to check what works for your computer before making any buying decision.
The time between the beginning of one random access memory (RAM) access to when the subsequent access begins is the Cycle time. This time is usually measured in nanoseconds. The PC4-21300 has a cycle time of 19ns.
I/O bus clock
The I/O bus clock of the PC4-21300 is 10650MHz. I/O bus clock is always half of the bus data rate.
Things to consider before buying a Memory module
The computer's RAM remains a crucial component for cutting-edge performance and efficient computing. Thus, buying one for your computer shouldn't be taken with levity. Here are a few things to consider when purchasing a RAM.
DDR4 memory is not compatible with a motherboard designed for DDR3 memory, and the same goes for other modules. Hence, you must ensure the RAM you buy is the specific type your motherboard needs.
