If more than one DIMM has experienced multiple CEs, other possible causes of CEs have to be ruled out by a qualified Sun Support specialist before replacing any DIMMs. Any ideas are greatly appreciated. b.

Retrieved 2011-11-23. ^ Benchmark of AMD-762/Athlon platform with and without ECC External links SoftECC: A System for Software Memory Integrity Checking A Tunable, Software-based DRAM Error Detection and Correction Library for So I gave up! Dust off the DIMMs, clean the contacts, and reseat them.

This used to be the case when memory chips were one-bit wide, what was typical in the first half of the 1980s; later developments moved many bits into the same chip. I was also able to reproduce the issue on a separate server using the same DIMM in question. You can either add a logo/image by embedding it directly into the signature or hosting it externally and linking to it. Error detection and correction depends on an expectation of the kinds of errors that occur.

Some ECC-enabled boards and processors are able to support unbuffered (unregistered) ECC, but will also work with non-ECC memory; system firmware enables ECC functionality if ECC RAM is installed. The banks on a two-sided DIMM are mismatched.
The DIMM generation (I or II) is mismatched. navigate here See FIGURE 3-2 for the locations of DIMMs and LEDs on the mezzanine board. Microsoft Research. Note - To recover fault information look in the SP SEL, as described in the Sun Integrated Lights Out Manager 2.0 User's Guide. 5.
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 Parity allows the detection of all single-bit errors (actually, any odd number of wrong bits).

Space satellite systems often use TMR, although satellite RAM usually uses Hamming error correction. Many early implementations
ECC also reduces the number of crashes, particularly unacceptable in multi-user server applications and maximum-availability systems. Guertin. "In-Flight Observations of Multiple-Bit Upset in DRAMs". this interface can be accessed for that u need to refer to the manual u had recieved with the system. I can not afford to play around with this server becuase it is a critical server that needs to stay up as much as possible. 0 Message Expert Comment
Details of my thread are here: http://forums.us.dell.com/supportforums/board/message?board.id=pes_oms&message.id=5384 Oh, also ran DOS Diags on the memory and it passed. ECC memory is used in most computers where data corruption cannot be tolerated under any circumstances, such as for scientific or financial computing. The system’s printed circuit boards and hard disk drives contain components that are extremely sensitive to static electricity. Let me know if you find a solution.
