CL21 and ECC are two important features of DDR4 SDRAM memory.
CL21 stands for "CAS Latency 21", which is a measure of the time it takes for a computer to access data stored in memory. Lower CL values typically indicate faster memory access times and better performance. CL21 is considered a standard latency for DDR4 SDRAM memory.
ECC stands for "Error-Correcting Code", which is a type of memory that can detect and correct single-bit memory errors. This feature is particularly useful in applications where data integrity is important, such as in servers and workstations, as it helps to reduce the likelihood of data corruption and system crashes. ECC DDR4 SDRAM is typically used in servers, workstations, and other high-performance systems where data integrity and reliability are critical.
When you see DDR4 SDRAM memory described as "CL21 ECC", it means that the memory has a CAS Latency of 21 and Error-Correcting Code feature. These features are designed to provide faster memory access times and improved data integrity, making it suitable for high-performance systems.
How Cl21 and Ecc Affect Memory PerformanceCL21 and ECC can both have an impact on memory performance, depending on the specific use case.
CL21, or CAS Latency 21, refers to the time it takes for the memory to access data stored in it. Lower CL values typically indicate faster memory access times and better performance. CL21 is considered a standard latency for DDR4 SDRAM memory, and it generally provides a good balance between performance and cost.
ECC, or Error-Correcting Code, is a feature that can detect and correct single-bit memory errors. This feature is particularly useful in applications where data integrity is important, such as in servers and workstations, as it helps to reduce the likelihood of data corruption and system crashes. ECC memory can also help to improve memory reliability, which can be beneficial for systems that run continuously or for long periods of time.
Using ECC memory can have a small performance impact on systems as it requires additional computation to detect and correct errors, but it's a tradeoff for the added data integrity it provides.
How to Determine Compatibility With Your MotherboardTo determine compatibility with your motherboard, you should check the following:
- CPU socket type: The CPU socket on your motherboard must match the socket type of your processor.
- RAM type and speed: The RAM type (DDR3, DDR4, etc.) and speed (1600 MHz, 2400 MHz, etc.) must match the specifications of your motherboard.
- Expansion slots: Make sure that the expansion slots on your motherboard match the type of expansion cards you plan to use (PCI, PCI-E, AGP, etc.).
- Power connectors: Check that the power connectors on your components (such as the CPU and GPU) match the connectors on your power supply.
- BIOS/UEFI: Make sure that the BIOS/UEFI version on your motherboard is compatible with the operating system you plan to use.
- Form Factor: The Form Factor of the motherboard must match the size of the case you have.
It is important to check the motherboard's manual and the specifications of the components before purchasing them. It is also a good idea to look at the product's website and compare the specifications of your motherboard and components to ensure compatibility.

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.
