ECC Memory is a computer data storage device. However this memory device is not like the many others because it is better capable of detect and correct internal corruption than others.
ECC stands for Error Checking and Correction. This type of memory module is used to correct memory errors within the computer registry. ECC memory modules generally have 9 chips compared to 8 chips in a non-ECC memory module. This is the easiest way to differentiate the two.
ECC modules can be used in a non-ECC system (though the cost makes it a poor strategy). Buffered modules cannot be used in a system that does not support buffered modules.
Generally speaking, yes. The memory will simply be accessed at the slower speed. However, do not mix memory modules of different speeds. Also do not mix non-ECC and ECC memory modules.
Depending on the specs of the motherboard, a motherboard that supports ECC SDRAM may support a non-ECC SDRAM module. If a motherboard can support both types, you would have the option to enable or disable the ECC feature in BIOS. Other than the fact that an ECC module has an odd number of chips, there is no other physical difference on the module. They are keyed the same.
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. - Neeraj Sharma
ECC cost more but is more reliable than non-ECC memory. TRUE
Yes you can. There's also an option in the CMOS setup to enable or disable this feature if your motherboard supports it.
No. When adding new memory, you need to match what is already in your system. Parity modules have an extra chip that detects if data was correctly read or written by the memory module, depending on the type of error. However, a parity module will not correct the erro

It is more reliable.
ecc momory can detect and repair errors
It is more reliable and is generally used on servers.
