ECC RAM is a special type of memory used for servers. ECC stands for Error Correction Code, which is an abbreviation in English.
Initially, ECC memory was only capable of error detection, and later the error correction mechanism was added. Mainly used for server systems, ECC, meaning “Error Correction Code“, is a system that repairs errors detected in RAM.
ECC RAM contains a special correction circuit. These error detection/correction circuits are used to identify and correct memory errors during data transfer. In a memory bit, Alpha and Beta particles can cause ionization and change the value of that bit “0->1 or 1->0,” a phenomenon called “bit flip.”
For server systems, parity memory was used in the past instead of ECC memory, and the system could detect a bit changed due to the bit flip phenomenon during memory reading; however, in this case, a “Parity Error” message was displayed, and the system would freeze. As a result, writing corrupted data was prevented, but all data was lost.
ECC can detect and correct a single bit changed in 64 bits due to the “bit flip” phenomenon, and this error can be interpreted as a two-bit error and treated accordingly. Thus, the server system operation is not interrupted. For ECC memory used in servers, a motherboard compatible with ECC must be used.
ECC RAM Prices
ECC memories are quite rare on the market. ECC RAM prices at Gigadata IT Technology products are very affordable. Also, for second-hand ECC RAM prices, please contact us. You can get information about models and features of second-hand memories in our stock by contacting us via contact.
ECC Server RAM Compatibility
Since ECC memories are specially produced for server motherboards and systems, they are fully compatible with these systems. If you want to use them in regular desktop systems, you need to check if the motherboard is compatible. It should be noted that very few motherboards are compatible with server memories. We do not recommend purchasing these products for regular systems without prior verification.
