ECC (Error Correction Code) is a technology used in RAM that detects and corrects errors that can occur during data storage and transmission. Here are some of the advantages of ECC technology:
- Improved System Reliability: ECC technology can detect and correct errors that occur during data storage and transmission. This improves the overall reliability of the system and reduces the likelihood of system crashes or data corruption.
- Increased Data Integrity: ECC technology can detect and correct single-bit errors that occur during data transfer, ensuring that data remains intact and accurate.
- Enhanced System Performance: ECC technology can help improve system performance by reducing the number of errors that occur during data transfer, resulting in fewer data retransmissions and faster processing times.
- Improved Memory Efficiency: ECC technology can reduce the amount of memory required to store data by using parity bits to detect and correct errors instead of duplicating data. This can lead to cost savings and improved memory efficiency.
- Greater Stability for High-Performance Applications: ECC technology is particularly important for high-performance applications such as servers, workstations, and data centers, which require high levels of data accuracy and reliability.
Non-ECC (Error Checking and Correction) and ECC (Error Correction Code) are two different types of memory technologies used in computer systems. Here are some of the key differences between them:
- Error Detection and Correction: ECC memory can detect and correct errors that occur during data storage and transmission, while non-ECC memory can only detect errors. This means that ECC memory is more reliable and less likely to experience data corruption or system crashes due to memory errors.
- Cost: ECC memory is typically more expensive than non-ECC memory due to the additional hardware required to support the error detection and correction features.
- Performance: ECC memory can be slightly slower than non-ECC memory due to the additional processing required for error detection and correction. However, the impact on performance is usually minimal and may not be noticeable in most applications.
- Compatibility: ECC memory is not compatible with all systems and requires a motherboard that supports ECC memory. Non-ECC memory, on the other hand, is compatible with most systems.
- Application: ECC memory is typically used in high-end servers and workstations that require high levels of data accuracy and reliability, while non-ECC memory is more commonly used in desktop and consumer systems.
The CL19 timing of the SNPVDFYDC/16G Dell RAM refers to the CAS (Column Access Strobe) Latency of the memory module. It represents the delay between the time when the memory controller sends a request for data and the time when the data is available to be read from the memory module.
In this case, a CL19 timing means that the memory module has a CAS latency of 19 clock cycles at a frequency of 2666MHz. The lower the CAS latency, the faster the memory can respond to requests from the CPU, which can result in better system performance.
However, it's important to note that the impact of CL latency on overall system performance may be minimal and can vary depending on the specific system configuration and workload. Other factors, such as memory capacity and bandwidth, can also play a significant role in determining system performance.

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. 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.
