It is more reliable.
ECC cost more but is more reliable than non-ECC memory. TRUE
It is more reliable and is generally used on servers.
You should use ECC memory because is uses an extra bit pre byte which is used for error checking and correctionn even though it is more cosly. Also, it is more reliable
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.
If you need to use a server with memory error protection for such critique services like financing, computer simulations and so on. You have to use ECC (error correcting code) memory which supports memory error protection. More information you can find here http://en.wikipedia.org/wiki/ECC_memory#Error-correcting_memory
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.
ECC memory is used in most computers where data corruption cannot be tolerated under any circumstances, such as for scientific or financial computing.
ecc momory can detect and repair errors
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
Because it is more reliable and is generally used on servers.
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.
