Solve : Memory or Motherboard issue?? |
|
Answer» Alright, so I am currently working at my college's lab trying to figure out what exactly is the cause of this blade's issues. It was donated to us (private college) and whomever donated to us said they wiped all data from the hard drives and we could do with it what we wanted to. I attempted to put Red Hat 9 on it to use it as a test server for some LABS for students but it froze multiple times, no luck. Decided to TRY and put Windows Server 2003 on it and it froze, once again no luck. I ran Memtest86 to see if it would diagnose anything and sure enough it did, within the first three seconds the test froze saying unexpected interrupt - halting CPU0. Try DIMM 1 and 3 first... It doesn't boot up with 1&3 / 2&4 - POST just yells Memory Error. Tried it. >.Why not swap some out of the other blades as well to test ? ? Other than that it sounds like that MBoard is fried...I contacted out IT department for documentation or possibly another blade to test it on. Like I said, it was donated so I'm not even sure if our college has another similar model. If I remember correctly, the blade doesn't even accept RAM if it's not ECC. Even that is hard to come by.

Quote from: Geek-9pm on February 24, 2010, 11:01:18 PM Ya! I have, getting those results. I believe it is a motherboard restriction, similar to how RAMBUS worked. If you have a module in DIMM1, you have to have one in DIMM2. Also, if you have a module in DIMM3 you have to have one in DIMM4. The only difference is that I can boot with two sticks of ram and not needing all 4. When I try to boot with a Module in DIMM2 and in DIMM3 it posts with beeps saying there is a memory error and I don't even get a video display. However, if I use the same exact sticks of RAM in DIMM1 and DIMM2 it boots into Memtest86 and I get those errors. Now, I'm still wondering if it is the motherboard (backplane) or a memory issue, or if there are any other diagnostic tools I could use that better describe issues other then memory locations and such. And to BC, a blade in my context is a server that can be mounted onto a rack. Form factors are measured like 1U, 2U, 4U, etc. The above poster with the picture is a better example. :pIf MemTest shows ANY errors at all it is faulty RAM sticks... Quote from: patio on February 25, 2010, 08:58:15 AM If MemTest shows ANY errors at all it is faulty RAM sticks... But I have never seen all four sticks compose errors, and ones that are so extremely similar to each other. Which is why I have a suspicion that it may be the motherboard. Which is why I was also asking if there are further diagnostic tools. If it was only one stick giving errors I would be more confident that it is a memory error.I don't follow this logic at all... A ) You are unable to boot with only 1 stik of RAM in this situation... B ) You can't use more than 1 slot configuration currently and boot successfully... Therefore it would take approx 96 runs of MemTest to determine the bad stick in a 2 stick 2 slot setup. Why not test this RAM 1 stick at a time outside the blade server ? ? Any desktop/laptop that takes that style/speed of RAM can be used... This would only require 4 runs of MemTest at most. Quote from: patio on February 25, 2010, 09:17:54 AM I don't follow this logic at all... I'm not sure where you got 96 tests at. I've finished testing each duo of sticks in 24 tests. The reason I haven't tested the ram sticks in another computer is because we are mainly housing old computers here. I.E RAMBUS Modules and 168-pin SDRAM. Otherwise I would have done that in a heartbeat. I am still awiting for a reply from IT to use a computer to test it on. Sadly.

Your IT department may have some. http://www.crucial.com/store/listparts.aspx?model=PowerEdge%20175096....24...sorry bad Math on my end. |
