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. RAID configuration may be selected via BIOS setup. this content

All four risers are required, and all must be populated with identical DIMM's, in all respects, in order to have the RAID option available bhanu 0 Message Expert Comment by:locutus212006-02-28 TABLE 3-1 describes the contents of the display: TABLE 3-1 Lines in IPMI Output Event (hex) Description 8 UCE caused a Hypertransport sync flood which lead to system's warm reset. #0x02 In addition, a DIMM should be replaced whenever more than 24 Correctable Errors (CEs) originate in 24 hours from a single DIMM and no other DIMM is showing further CEs. Note - Disconnecting the AC power removes the fault indication.
Remote console and > reset/on/off is good enough for me. Single Bit Error Logging Disabled NOTE: Label each memory module with the riser card letter and connector number to which it was connected. Chipkill ECC is a more effective version that also corrects for multiple bit errors, including the loss of an entire memory chip. http://www.dslreports.com/forum/r25455469-ECC-Single-bit-fault Thus, accessing data stored in DRAM causes memory cells to leak their charges and interact electrically, as a result of high cells density in modern memory, altering the content of nearby

The latter is preferred because its hardware is faster than Hamming error correction hardware. Space satellite systems often use TMR, although satellite RAM usually uses Hamming error correction. Many early implementations However, on November 6, 1997, during the first month in space, the number of errors increased by more than a factor of four for that single day.

A few systems with ECC memory use both internal and external EDAC systems; the external EDAC system should be designed to correct certain errors that the internal EDAC system is unable http://deepfrom.com/ecc-error/ecc-error-correction-detected-on-bank-3-dimm-b.html Reconnect the system to the electrical outlet, and turn on the system and attached peripherals.

Johnston. "Space Radiation Effects in Advanced Flash Memories". http://deepfrom.com/ecc-error/ecc-error-correction-detected-in-bank-1-dimm-b.html I am pretty sure that the memory stick is bad.
The MCT stopped due to errors in the DIMM. I look forward to trying the open-source ipmitool package for SOL and other functions. share|improve this answer answered Dec 22 '12 at 20:09 mfinni 31.2k33474 I'm just wanting to verify that hardware is the only issue at fault here.

Hsiao showed that an alternative matrix with odd weight columns provides SEC-DED capability with less hardware area and shorter delay than traditional Hamming SEC-DED codes. DIMM fault LED is off - The DIMM is operating properly.

The DIMMs do not support ECC. In systems without ECC, an error can lead either to a crash or to corruption of data; in large-scale production sites, memory errors are one of the most common hardware causes
