DDR4 SDRAM (Double Data Rate 4 Synchronous Dynamic Random Access Memory) is the latest version of DDR memory technology. It is a type of memory used in computers and servers for temporary data storage and processing. DDR4 SDRAM offers several advantages over its predecessor (DDR3) such as increased memory capacity, improved power efficiency, faster speeds and lower operating voltages. DDR4 also provides higher stability and improved signal integrity, making it ideal for demanding applications and high-performance systems. The DDR4 standard uses a 288-pin DIMM form factor and operates at speeds ranging from 2133 MHz to 4266 MHz. Overall, DDR4 SDRAM is a significant improvement over previous generations of DDR memory and is widely adopted in the market.
Ecc Registered 2666MHZ PC4-21300 Cl19ECC (Error Correction Code) Registered refers to a memory technology that provides error detection and correction capabilities. The ECC function can detect and correct single-bit errors in real-time, ensuring data integrity and preventing system crashes. This feature makes ECC Registered memory a popular choice for enterprise-level systems and applications where data loss or corruption is unacceptable.
2666MHz is the operating frequency of the M386A8K40BM2-CTD6Q Samsung DDR4 SDRAM memory module. This speed indicates the rate at which the memory module can transfer data and perform memory operations.
PC4-21300 is a standard for DDR4 memory that defines the maximum data transfer rate, clock frequency, and other electrical and timing specifications. The PC4-21300 standard specifies a maximum data transfer rate of 2666 MB/s, making the M386A8K40BM2-CTD6Q DDR4 SDRAM memory module compatible with motherboards that support this standard.
CL19 is a latency timing measurement that represents the number of clock cycles it takes for the memory module to complete a memory access operation. The lower the CL value, the faster the memory module is able to perform operations, improving overall system performance. A CL19 latency timing for the M386A8K40BM2-CTD6Q DDR4 SDRAM memory module indicates that it is able to perform operations efficiently and quickly.

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. 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.
Final Sale items are non-returnable/refundable in any situation. Any question? please ask our team before the shipment.
