If it is only correctable errors in a low rate you can probably live with it and in any case for correctable errors it will be harder to get a refund. Do you have IPMI? size_mb : An attribute file that contains the size (MB) of memory that this memory controller manages. 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 http://centralpedia.com/memory-error/uncorrectable-error-status-an-uncorrectable-error-occurred.html
During their investigations they found that one third of the machines and more than 8 percent of the DIMMs saw correctable errors per year. However, in practice multi-bit correction is usually implemented by interleaving multiple SEC-DED codes. Early research attempted to minimize area and delay in ECC circuits. The bang (!) Light Emitting Diode (LED) on the BladeCenter chassis as well as the server will turn off when the blade is power cycled.

The definition of each file is: ce_count : The total count of correctable errors that have occurred on this csrow (attribute file). b_cimc_reset_0.png [Troubleshooting for Standalone C-Series]Basically, it will be the same troubleshooting as for B-Series.1. The incidence of correctable errors increases with age, but the incidence of uncorrectable errors decreases with age The increasing incidence of correctable errors sets in after about 10–18 months.

Do pulled hair from the root grow back? Correctable Memory Error Rate Exceeded For Dimm Tsinghua Space Center, Tsinghua University, Beijing. Radhome.gsfc.nasa.gov. The system may be described as having reported CPU or memory errors Example error messages which may have been reported are shown below: Name(required) Email(required) Learning Request(required) Are you Looking for
The lower number is just about one error per gigabit of memory per hour. ISBN978-1-60558-511-6. Uncorrectable Ecc Error If you're getting them significantly faster than that, or if they're multi-bit errors, you should be worried (I would replace the RAM ASAP). Uncorrectable Ecc Error Encountered There were some issues on some SM Opteron boards that had a BIOS fix, not sure if that would apply here.
It was running CentOS 6.2 during the tests.For the test system, I checked to see whether any EDAC modules were loaded with lsmod :login2$ /sbin/lsmod ... have a peek at these guys Not in a data center yet, but very soon. Retrieved October 20, 2014. ^ Single Event Upset at Ground Level, Eugene Normand, Member, IEEE, Boeing Defense & Space Group, Seattle, WA 98124-2499 ^ a b "A Survey of Techniques for The system locked up again today with a blank screen. Correctable Ecc Memory Error Logging Limit Reached
The memory slots are color-coded and interleaved for the quad-channel setup. System is way underpowered for this, but this is all I've got. It's possible that the cumulative error passes ECC; that would show up as an OS crash or similar problem. check over here Wikipedia® is a registered trademark of the Wikimedia Foundation, Inc., a non-profit organization.
I threw the extra two Viking modules in to see if it worked and it did. Correctable Memory Error Rate Exceeded For Dimm A1 The motherboard specification says that ram modules must be installed in sets of four as the processor uses quad-channel memory controller. Retrieved 2015-03-10. ^ Dan Goodin (2015-03-10). "Cutting-edge hack gives super user status by exploiting DRAM weakness".
Sorin. "Choosing an Error Protection Scheme for a Microprocessor’s L1 Data Cache". 2006. These extra bits are used to record parity or to use an error-correcting code (ECC). H. Correctable Memory Error Has Been Detected In Memory Slot I'm currently building a replacement (new mb/cpu/ram/psu) to expand capacity with a second processor; once I have it completed I will be performing must more rigorous testing on the old system

A 2010 simulation study showed that, for a web browser, only a small fraction of memory errors caused data corruption, although, as many memory errors are intermittent and correlated, the effects
