UCEs occur and investigation shows that the errors originated from memory. Get 1:1 Help Now Advertise Here Enjoyed your answer? Retrieved 2009-02-16. ^ "Actel engineers use triple-module redundancy in new rad-hard FPGA". Retain copies of the logs showing the memory errors per the above rules to send to Sun for verification prior to calling Sun.
The banks on a two-sided DIMM are mismatched. DIMM Replacement Policy Replace a DIMM when one of the following events takes place: The DIMM fails memory testing under BIOS due to Uncorrectable Memory Errors (UCEs). Y. At this time, CEs are not logged in the server’s system event logs.
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. Remove all memory modules from the memory riser cards. The consequence of a memory error is system-dependent. https://docs.oracle.com/cd/E19121-01/sf.x4140/820-3067-14/dimms.html 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
What should I do? Modern implementations log both correctable errors (CE) and uncorrectable errors (UE). ECC may lower memory performance by around 2–3 percent on some systems, depending on application and implementation, due to the additional time needed for ECC memory controllers to perform error checking. As a result, the "8" (0011 1000 binary) has silently become a "9" (0011 1001).

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 current community blog chat Server Fault Meta Server Fault your communities Sign up or log in to customize your list.
Implementations Seymour Cray famously said "parity is for farmers" when asked why he left this out of the CDC 6600. Later, he included parity in the CDC 7600, which caused pundits Each pair of DIMMs must be identical (same manufacturer, size, and speed).

You could try some memory test diagnostics to see if it is reading some of the memory on the DIMM and identify definately if it is the DIMM or the MB Interleaving allows for distribution of the effect of a single cosmic ray, potentially upsetting multiple physically neighboring bits across multiple words by associating neighboring bits to different words. Jet Propulsion Laboratory ^ a b Borucki, "Comparison of Accelerated DRAM Soft Error Rates Measured at Component and System Level", 46th Annual International Reliability Physics Symposium, Phoenix, 2008, pp.482–487 ^ a
See FIGURE 3-2 for the locations of DIMMs and LEDs on the mezzanine board.
Retrieved 2011-11-23. ^ "FPGAs in Space". I have taken out the memory that was giving the error, I just thouht it was strange that it occured every 3 hours. 0 Question by:jamessa Facebook Twitter LinkedIn Google LVL The BIOS in some computers, when matched with operating systems such as some versions of Linux, Mac OS, and Windows, allows counting of detected and corrected memory errors, in part Review the log file.
Recent studies show that single event upsets due to cosmic radiation have been dropping dramatically with process geometry and previous concerns over increasing bit cell error rates are unfounded.

The applications or services that hold your registry file may not function properly afterwards. Access Event Viewer through this menu path: Start-->Administration Tools-->Event Viewer c. Inspect the installed DIMMs to ensure that they comply with the DIMM Population Rules. 3. The user can then view individual errors (by time) to see details of the error.
The DIMMs do not support ECC. However, unbuffered (not-registered) ECC memory is available, and some non-server motherboards support ECC functionality of such modules when used with a CPU that supports ECC. Registered memory does not work reliably Motherboard Fault LED on mezzanine is on - There is a fault on the motherboard. Dust off the DIMMs, clean the contacts, and reseat them.
