What is non-ECC DDR SDRAM memory?
There are two types of memories when it comes to supporting ECC
(error correction code/circuitry). These are ECC memory (memories
which support ECC) and non-ECC (which do not support ECC). ECC
helps detect and correct certain types of errors in memory
transactions if they occur. ECC memories are a bit slow in
performance as there is some time lost in detecting and correcting
errors if they occur. Non-ECC memories are more common, faster and
cheaper. ECC memories are recommended for servers and other mission
critical applications. Most of system designs and circuits are
robust and there are rarely any errors on a PC memory bus, so
non-ECC memories are good enough for general computing
applications. Most computer motherboards support both type of
memories but still if one should check motherboard and BIOS
specifications before investing in ECC memory type.
