Non-ECC (Error Correction Code) and ECC memory modules are types of RAM (Random Access Memory) used in computers. The primary difference between the two is their error correction capabilities.
Non-ECC Memory Modules: Non-ECC memory is the standard type of RAM used in most computers. It does not have any error checking or correction capabilities. If there is a memory error, non-ECC memory will not detect it, and the system will continue to operate with the corrupted data. Non-ECC memory is suitable for most users who do not require high levels of reliability or data integrity.
ECC Memory Modules: ECC memory modules, on the other hand, have an additional circuitry that can detect and correct single-bit errors in memory. This error correction feature improves system reliability and data integrity by identifying and fixing any errors that occur in memory. ECC memory is used in applications that require high levels of reliability, such as in servers, workstations, and mission-critical systems.
The drawback of ECC memory is that it is more expensive than non-ECC memory and requires special hardware support. Additionally, ECC memory may slightly lower the performance of a system due to the additional processing required for error correction.
Unbuffered vs Buffered Memory ModulesUnbuffered and buffered memory modules are two types of RAM (Random Access Memory) that differ in the way they handle signals from the memory controller.
Unbuffered Memory Modules: Unbuffered memory, also known as unregistered memory, is the most common type of RAM used in computers. It is a type of memory that connects directly to the memory controller without any additional hardware. Unbuffered memory is easy to install and has lower latency, which means it responds more quickly to requests from the processor. However, it is less scalable than buffered memory and has limitations on the number of modules that can be installed on a motherboard.
Buffered Memory Modules: Buffered memory, also known as registered memory, has an additional buffer between the memory controller and the memory module. The buffer helps to improve signal integrity and reduce electrical noise, which makes it possible to have more memory modules on a single motherboard. Buffered memory is commonly used in high-performance computing and server applications where large amounts of memory are required. However, buffered memory has higher latency and is more expensive than unbuffered memory.
CompatibilityCompatibility is an important consideration when selecting and upgrading memory modules for a computer system. Incompatible memory modules can cause system instability, crashes, and other issues. Here are some factors to consider when determining memory module compatibility:
- Memory Type: Check the type of memory supported by the motherboard, such as DDR3 or DDR4. Ensure that the memory module you choose is compatible with the motherboard's memory type.
- Memory Speed: The memory speed is the maximum frequency at which the memory can operate. Ensure that the memory module speed matches the maximum memory speed supported by the motherboard.
- Memory Capacity: Check the maximum memory capacity supported by the motherboard. Ensure that the memory module capacity does not exceed the maximum memory capacity supported by the motherboard.
- Memory Voltage: The memory voltage is the amount of power required for the memory to operate. Ensure that the memory module voltage matches the voltage supported by the motherboard.
- Memory Form Factor: The memory form factor refers to the physical size and shape of the memory module. Ensure that the memory module form factor is compatible with the motherboard's memory slots.
- Manufacturer Compatibility: Check the motherboard and memory module manufacturer's compatibility lists to ensure that the memory module is compatible with the motherboard.

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;

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).
