- Key Specs
- Type of Memory (RAM): DDR4
- Form Factor: Laptop (The type of computer the memory is configured to fit in.)
- Speed: 2666 megahertz
- Latency: 19 (Refers to the amount of time between the moment a memory request is initiated and the moment the request is retrieved by a processor, commonly written as a series of 4 numbers, or timings. Each timing measures the performance of the module according to a specific parameter. Generally, the lower the numbers, the faster the RAM can respond to requests.)
- CAS Latency: 19 (Column Address Strobe (CAS) Latency refers to the number of clock cycles (for synchronous DRAM) or nanoseconds (for asynchronous DRAM) between the moment an instruction or command is initiated and the moment the data result is available. Generally, the lower the numbers, the better.)
- Lighting Type: None
- Performance Profile(s): Not Applicable
- Memory Capacity (per Module): 16 gigabytes (Refers to the maximum amount of data that can be stored on the memory module.)
- Memory Capacity (Total): 64 gigabytes (Refers to the maximum total amount of data that can be stored on all included memory modules.)

- Speed
- Memory Speed Rating: PC4-21300 (The RAM's bandwidth rating. The numbers refer to generation and transfer speed and are typically separated with a hyphen. For example, PC3-12800 would indicate that the module is 3rd generation and has a theoretical bandwidth of 12,800 megabytes per second (MBs). The higher the second number, the faster the speed.)

- Features
- Buffered or Registered: Unbuffered (Registered (buffered) memory modules are classified by the addition of a register between the memory controller and DRAM modules. When compared to conventional unbuffered (unregistered) memory, this type provides more stability with less electrical load on the controller, making it a common choice for use in robust applications, such as servers.)
- Data Integrity Check: Non-ECC (Error-correcting code (ECC) memory helps to maintain data integrity within a computer system, protecting it from potential crashes as well as losses or changes to data due to undetected errors. Systems that use ECC have an additional chip on the RAM that acts as the error check.)
- Memory Channels: Dual (Multi-channel memory increases the rate of data transfer between the DRAM memory and memory controller by adding more channels of communication. The more channels, the more memory bandwidth.)
- Lighting Type: None
- Fan Included: false
- Performance Profile(s): Not Applicable
- Power
- Voltage: 1.2 volts (Amount of power needed to support an electrical current.)
