We need to look at the signal integrity of the read data to see if the DIMM has problems. All of this and MORE, much more, validation and test should occur before the platform ever sees the light of day and a Validation Repor t generated. If failures are occurring in the field a Memory Channel Audit can be performed.

We look for all the evidence that most likely contributes to problems and we compile a list of things that can be changed and the system re-tested to see if that reduces the ECC errors. So far our team is batting a with documented proof of problems and suggested fixes that led to positive results. Got DDR problems? Contact us. Your name. Your email. Tell us about yourself! Tell us about yourself. Error correction code is a mathematical process that ensures the data stored in memory is correct.

In the case of an error, ECC also allows the system to recreate the correct data in real time. ECC uses a more advanced form of parity, which is a method of using a single bit of data a parity bit to detect errors in larger groups of data, such as the typical eight bits of data used to represent values in a computer memory system.

Unfortunately, while a parity bit allows the system to detect an error, it doesn't provide enough information to correct the data error.
