CAS Latency, or Column Address Strobe Latency, is a measure of the delay between the memory controller sending a command to access a specific memory location and the memory module actually returning the requested data. It is measured in clock cycles and represented by the acronym "CAS".
A lower CAS latency means that the memory is faster and more responsive, as it takes less time for the memory to return the requested data. A higher CAS latency means that the memory is slower and less responsive, as it takes more time for the memory to return the requested data.
The impact of CAS latency on memory performance depends on the specific application and the workload that the memory is being used for. In general, lower CAS latency memory is better suited for applications that require fast data access and high-speed data transfer, such as gaming, video editing and other high-performance computing tasks.
However, it's important to note that CAS latency is not the only factor that affects memory performance. Other factors such as memory capacity, clock speed, and memory bandwidth also play a role in determining the overall performance of the memory.
The Role of ECC Technology in the HPE 64GB 2400MHZ PC4-19200 Cas-17 EccECC technology, or Error Correcting Code technology, is a feature that is built into the HPE 64GB 2400MHZ PC4-19200 Cas-17 Ecc memory module to detect and correct errors that may occur in the memory during operation. ECC memory is designed to provide an additional level of data protection and reliability, and is typically used in mission-critical systems and applications where data integrity is of the utmost importance.
ECC technology works by adding an additional bit of data to each memory cell, called a parity bit, which is used to detect and correct errors that may occur in the data stored in the memory. The memory controller checks the parity bit when data is read from the memory, and if an error is detected, the memory controller will correct the error using the parity bit.
The HPE 64GB 2400MHZ PC4-19200 Cas-17 Ecc memory module is built with a 72-bit chip, which includes 64 bits of data and 8 bits of ECC. This allows the memory controller to detect and correct single-bit errors, as well as detect and alert the system of multi-bit errors.
How Registered Memory Improves System PerformanceRegistered memory, also known as buffered memory, is a type of memory that uses a register, or buffer, between the memory controller and the memory module to improve system performance. The register, or buffer, acts as an intermediary between the memory controller and the memory module, and helps to regulate the flow of data between the two.
There are a few key ways in which registered memory improves system performance:
- Increased memory capacity: Registered memory allows for the use of more memory modules in a system, which can increase the overall memory capacity of the system.
- Improved signal integrity: The register, or buffer, in registered memory helps to improve the signal integrity of the data being transferred between the memory controller and the memory module. This can help to reduce errors and improve system performance.
- Increased clock speed: Registered memory can support higher clock speeds than non-registered memory, which can improve system performance by allowing for faster data transfer speeds.
- Improved memory stability: Registered memory is less prone to errors and system crashes caused by memory instability, which can improve system performance and uptime.

Other Available Conditions for this Part
Warranty
ALLHDD guarantees that the products will not have defects in material that will affect the product's functionality during the Standard Warranty Period. The warranty period starts when the merchandise/items from our warehouse.
What does ALLHDD.Com warranty cover?
30-days to 3 years warranty:
Replacement or refund. In the case of material defects, we will try to replace the product first. The product will be replaced before the expiration of the original warranty. For any failure of hardware, if we cannot process the replacement of the product(s)/model(s), we will refund the original selling/invoiced price. The shipping costs and sales tax, if any, are non-refundable. ALLHDD retains the right to decide whether the item(s) will process for replacement or refund.
What is not covered by our warranty?
The reason why our warranty does not cover any problem caused by the following conditions:
(a) misuse of hardware; accidental damage; carelessness product(s) damage; shock; temperature beyond the specification of any product; faulty installation; operation; modification of goods;
(b) any misuse outside the instructions in the user manual for any specific product;
(c) damaged caused by other hardware or equipment.
