Double bit error in flash … Error correction code memory (ECC memory) is a type of computer data storage that uses an error correction code (ECC) to detect and correct n-bit data corruption which occurs in memory. ECC memory is used in most computers where data corruption cannot be tolerated, like industrial control applications, critical databases, and infrastructural memory caches. oriaths end

WebRegisters & Buffers have absolutely nothing to do with ECC. Its technically possible to have registered ram with no ECC, though a lot of firmware might decide that is a hardware failure and halt booting or not use the slot. Unbuffered ECC of the same generation is no different than Registered ECC: same detection and correction capabilities. Web2. Refreshing the SDRAM has no effect on errors and cannot be used to help an ECC system; the two features are separate systems. However the opposite may work; implementing a certain type of ECC scheme, you can also refresh the memory as a side effect, and switch off the "auto-refresh" logic.
