ECC Registered DDR4 SDRAM
ECC Registered DDR4 SDRAM (Error-Correcting Code Registered Double Data Rate 4 Synchronous Dynamic Random Access Memory) is a type of RAM that is designed for high-performance computing systems that require reliable and accurate data storage and processing.
The ECC feature in this type of RAM helps detect and correct errors that can occur during data storage and processing. This is achieved by adding extra bits to each data block, which is used to detect and correct errors in real-time.
The registered feature in this type of RAM allows it to handle larger amounts of memory and also helps to reduce the load on the memory controller, thereby improving overall system performance.
DDR4 SDRAM is the fourth generation of DDR RAM, and it offers improved performance and power efficiency compared to DDR3 RAM. DDR4 SDRAM operates at a higher clock speed and has a higher bandwidth than DDR3, which allows for faster data transfer rates and better overall system performance.
CAS Latency (CL) Explained
CAS latency (CL) is a measure of the delay between the time a memory controller sends a request for data from the RAM and the time the data is actually available. It is a timing value that is associated with DDR RAM and is usually expressed as a number, such as CL16 or CL19.
The CAS latency is measured in clock cycles, which are determined by the operating frequency of the RAM. The lower the CAS latency value, the fewer clock cycles are needed to access the data, which results in faster access times and improved system performance.
For example, if a RAM module has a CAS latency of 16, it means that it takes 16 clock cycles for the data to be available after the memory controller sends a request. If another module has a CAS latency of 19, it would take 19 clock cycles for the data to be available.
However, it is important to note that CAS latency is just one of several timing values associated with DDR RAM, and it is not the only factor that affects overall performance. Other timing values, such as tRAS (Active to Precharge Delay) and tRP (Row Precharge Time), also play a role in determining RAM performance.
When selecting RAM for a system, it is important to consider all the timing values and other specifications to ensure that the RAM is compatible with the motherboard and that it provides the desired performance for the system.
Understanding the 288-Pin RAM format
The 288-Pin RAM format refers to the physical design of DDR4 SDRAM modules that are commonly used in modern computer systems.
The 288-Pin RAM format consists of a rectangular circuit board with 288 metal pins on the bottom edge of the module that plug into a corresponding 288-pin slot on the motherboard. The pins are arranged in a specific pattern that is designed to ensure proper alignment and electrical connectivity with the motherboard.
The 288-Pin RAM format is used exclusively for DDR4 SDRAM, which is the most common type of RAM used in modern computer systems. DDR4 SDRAM is designed to operate at a higher clock speed and provide improved performance compared to earlier generations of DDR RAM, such as DDR3 and DDR2.
The 288-Pin RAM format is available in a variety of capacities, ranging from 4GB to 64GB or more. The physical size of the module varies depending on the capacity and manufacturer, but most modules are around 133.35mm (5.25 inches) long and 31.25mm (1.23 inches) tall.
When installing RAM in a computer system, it is important to ensure that the RAM is compatible with the motherboard and that it is installed correctly in the 288-pin slot. Improper installation or compatibility issues can lead to system instability, crashes, or other issues.

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. The warranty will void if the item is returned with physical damage, damage to the retail box, removed from the box, counterfeit labels/labelled by them, or any modifications of internal and external covers. Data loss or damages to any other equipment we do not cover by our offered warranty.
What is the Manufacturer/Brand Warranty?
In general, a manufacturer's warranty service/support is a written guarantee to the buyer of a product. Its terms assure the replacement or repair of the product, if necessary, within a specified period after the purchase (2-5 years depending on the brand/manufacturer). It is typically included in the price of the product. Products are brand new and sealed and the original manufacturer box is complete with the Manufacturer's genuine warranty. For most of the brand new/retail products that come with the manual and box, exceptions may apply (i.e., Cisco, Juniper Networks).
For the server parts (i.e., Dell, HPE) to get Full coverage of the warranty server must have a full 3- 5 years warranty. However, ALLHDD.COM will cover the warranty duration if any Manufacturer doesn't support the advertised warranty and there is no refund for those.
