Hanji writes "We have discussed here before the potential effects of and protections against cosmic ray radiation, but for the average computer user, it's an obscure threat that doesn't affect them in any real way. Well, here's a blog post that describes a strange segfault and, after extensive http://capita.wustl.edu/capita/people/AGonzalez/VigorDoc/9437/messages.htm debugging, traces it down to a single bit flip, probably caused by a stray cosmic ray. Lots of helpful descriptions of Linux debugging techniques in this one, and a pretty clear demonstration that this can be a real problem. I know I'm never buying a desktop without ECC RAM ever again!" The author acknowledges that it might not have been a cosmic ray-based error, but the troubleshooting steps are interesting https://it.slashdot.org/story/10/06/24/2210214/tracking-down-a-single-bit-ram-error no matter what the cause. bug hardware ram ← Related Links → Rats Breathe Air From Lungs Grown In the Lab Experimental Magnetic Shield Against Cosmic RaysDo Car Safety Problems Come From Outer Space?Submission: Blogger shows that cosmic rays are a real problem Nokia Trades Symbian For MeeGo In N-Series Smartphones This discussion has been archived.

I guess :D Working on Dells, I would assume that you all have OpenManage installed on your servers. Have you ever received an alert about DIMMs on Dell http://blog.open-tribute.org/2013/03/dell-single-bit-warnings-error.html servers? Looking at the logs you get: # omreport chassis Health Main System Chassis SEVERITY : COMPONENT Non-Critical : Memory Ok : Power Management Ok http://www.techrepublic.com/forums/discussions/why-would-the-bios-return-a-memory-error-on-a-random-dimm-slot/ : Processors [...] # omreport system alertlog Alert Log Alert Log contains... Severity : Non-Critical ID : 1403 Date and Time : memory error Thu Feb 28 20:36:14 2013 Category : Instrumentation Service Description : Memory device status is non-critical Memory device location: DIMM_A4 Possible memory module event cause:Single bit warning error rate exceeded [...] You called straight away the Dell Call centre, waited and received an answer like: "Try this command ... or this command ... have you tried to power it off and on again?" correctable memory error Well, I did a while ago! Just don't fire at the Dell techs! It's their job to ask you all those questions, as much as it is your job to get it resolved quickly. Guess what, unless this becomes a real issue, you don't need to call Dell Call centre anymore. After all, this is a Non-Critical issue. It basically means that the memory found an error and corrected for it. So what I would advise, is, calm down, drink some tea, and just clear the memory failures! On linux, you can clear them with: #/opt/dell/srvadmin/sbin/dcicfg command=clearmemfailures When printing again the health of your server, everything will be OK!! But, if this happens again, on the same DIMM, in a few weeks time, your DIMM or slot might have real problem. In this case, open your server and swap memory in this slot with another slot. For example, sap DIMMs between slot 4 (in this case) and slot 8. If it happens on slot 8, then you have a bad memory. If it happens again on slot 4, then you slot is bad, so you'll need to change your motherboard ... now you can call Dell

By jtjenkins213 ยท 5 years ago On a Dell Precision desktop T3500 with Windows XP Professional 64-bit installed, the operating system was consistently receiving BSOD screens (actual BSOD, as in a hard stop and not a general page fault). When I ran the Dell hardware tests, the memory came back as bad. It currently has 4-1GB DDR3 1333 DIMMs installed.I researched the type of memory that the system would support, and purchased 3-4GB DDR3 1333 ECC memory as an upgrade. When I installed the memory, I received a beep code of 1-3-2. According to the Dell website, that is a memory error. Thinking I may have for some reason ordered the wrong memory, I put the old memory back in. Once again, I heard the beep code, same error.I contacted Dell Tech Support, and they had me run through the motions of troubleshooting (take all memory out but one, try each slot, insert one at a time). Eventually they determined that it was not the memory but the systemboard. So according to our service agreement, I had them send a tech out to replace it on site. Next day, the tech came, replaced the system board. Tried the new memory, received the same error, 1-3-2 beep code. He called tech support, went through the same thing I did. Mysteriously, however, when he put a single 1GB DIMM in, he received the beep code. He then hit the power button accidentally twice (double-tap) which shut power off and turn back on-It then worked. It went through POST and gave the message of system memory size has changed. So he added a second 1 GB DIMM, and same thing, beep code, power off, power on, and it boots but it gives an error stating an error on DIMM2. So he takes that DIMM out and replaces it with the third 1GB DIMM. Same issue, error on DIM
