Uncorrectable Memory Error ((processor 1 Memory Module 3))
Subscriber MCS7825 HP server, we have a amber light flashing on one uncorrectable memory error (system memory, memory module 0) of the LED's. I checked RTMT and found the following alert under Hardware Failure: At Fri Mar 13 20:05:38 correctable error threshold exceeded CDT 2009 on node 10.6.110.11, the following HardwareFailure events generated: hwStringMatch - hpasmxld[8319]: WARNING: Corrected Memory Error threshold exceeded (System Memory, Memory Module 1) I haven't been able to find https://community.hpe.com/t5/HPE-BladeSystem-Server-Blades/Memory-Error-threshold-exceeded-error/td-p/5828989 much information on this error and this is the only occurance from the syslog viewer. Has anyone run into this before and is it reason to open a TAC case for further investigation? Thanks, Brian rratliff at cisco Mar26,2009,8:46AM Post #2 of 2 (4011 views) Permalink Re: Subscriber - Corrected Memory Error threshold exceeded alert [In reply to] Yes you should contact http://www.gossamer-threads.com/lists/cisco/voip/106474 TAC so they can open a case with HP to replace that memory module. -Ryan On Mar 26, 2009, at 11:33 AM, Brian wrote: On our Subscriber MCS7825 HP server, we have a amber light flashing on one of the LED's.

computer data storage that can detect and correct the most common kinds of internal data corruption. ECC memory is used in most computers https://en.wikipedia.org/wiki/ECC_memory where data corruption cannot be tolerated under any circumstances, such as for http://serverfault.com/questions/382567/does-it-make-sense-to-install-online-spare-memory 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 memory error to the wrong state. Most non-ECC memory cannot detect errors although some non-ECC memory with parity support allows detection but not correction.

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-p

I need a pretty reliable server, so I'm using RAID1 with a spare drive, and I also added an extra power supply. But should I install online spare memory?

With ECC RAM and running HP management agents, it's pretty easy to detect bad memory. There are typically a few steps to intervene before you see a major problem that affects operation. Under standard support, RAM replacement is next-business-day, so there's no need to complicate your RAM arrangement by adding spare DIMMs. The worst HP ProLiant memory issue I had on a system eventually crashed the server after several ECC alerts that occurred over the course of a week. The errors came, the server rebooted through an ASR and the machine came back up with the bad DIMM disabled. This was an HP ProLia
