There are solution provided by Cisco as below; Core issue This error message indicates that the system is self-correcting a transient https://www.experts-exchange.com/questions/28693898/The-SYSTEM-CONTROLLER-3-COR-MEM-ERR-Correctable-DRAM-memory-error-message-is-received-in-the-Cisco-Catalyst-6500-switch-running-Cisco-IOS-software.html DRAM error. Resolution No action is needed if this error occurs only once. However, if the error message occurs again within 24 hours, perform these steps: Schedule a downtime and re-seat the Synchronous Dynamic Random-Access Memory Dual In-line Memory Modules (SDRAM SIMM) on the Supervisor (SUP) engine. If errors persist, replace the SIMM. If errors persist after the memory is replaced, then please contact Cisco Technical Support online using the TAC Service Request Tool. - See more at: https://supportforums.cisco.com/document/18671/systemcontroller-3-cormemerr-correctable-dram-memory-error-message-received-cisco#sthash.H3498GIk.dpuf Is there any impact if we ignore this issue ? anyone has prior experience on this ? 0 Question by:Deepak Muralidharan Facebook Twitter LinkedIn Google LVL 24 Active today Best Solution byPredrag Jovic Translation: If error occurs constantly (maybe it is bad contact of RAM and memory slot) Re-seat RAM if error still occurs (it was not bad contact - could be RAM has BAD blocks) Replace RAM If error Go to Solution 3 Comments LVL 24 Overall: Level 24 Switches / Hubs 16 Network Architecture 9 Networking Hardware-Other 9 Message Active today Accepted Solution by:Predrag Jovic2015-07-01 Translation: If error occurs constantly (maybe it is bad contact of RAM and memory

computer data storage that can detect and correct the most common kinds of internal data corruption. ECC memory is used in most computers where data corruption cannot be tolerated under any circumstances, such as for scientific or financial computing. Typically, ECC memory maintains a memory system immune to single-bit errors: the data that is read from each word is always the same as the data that had been written to it, even if one or more bits actually stored have been flipped to the wrong state. Most non-ECC memory cannot detect errors although some non-ECC memory with parity support allows detection but not correction. Contents 1 Problem background 2 Solutions 3 Implementations 4 Cache 5 Registered memory 6 Advantages and disadvantages 7 References 8 External links Problem background[edit] Electrical or magnetic interference inside a computer system can cause a single bit of dynamic random-access memory (DRAM) to spontaneously flip to the opposite state. It was initially thought that this was mainly due to alpha particles emitted by contaminants in chip packaging material, but research has shown that the majority of one-off soft errors in DRAM chips occur as a result of background radiation, chiefly neutrons from cosmic ray secondaries, which may change the contents of one or more memory cells or interfere with the circuitry used to read or write to them.[2] Hence, the error rates increase rapidly with rising altitude; for example, compared to the sea level, the rate of neutron flux is 3.5 times higher at 1.5km and 300 times higher at 10–12km (the cruising altitude of commercial airplanes).[3] As a result, systems operating at high altitudes require special provision for reliability. As an example, the spacecraft Cassini–Huygens, launched in 1997, contains two identical flight recorders, each with 2.5gigabits of memory in the form of arrays of commercial DRAM chips. Thanks to built-in EDAC functionality, spacecraft's engineering telemetry reports the number of (correctable) single-bit-per-word errors and (uncorrectable) double-bit-per-word errors. During the first 2.5years of flight, the spacecraft reported a nearly constant single-bit error rate of about 280errors per day. However, on November 6, 1997, during the first month in space, the number of er
