    BSOD - Memory Management?


    I've experienced 3 or 4 BSOD's in the past two weeks. I have attached the required file.

    I have not seen a pattern in my activity that might be related.

    I wrote "Memory Management" in the subject line because that was what I saw at the top of the BSOD.
    I did not notice if that was present during the previous BSOD's.


    Thanks so much for your help. :)

    Hello, Jeff1961. I will try to help you with this. I looked at your last 5 dump files, 4 of them gave this

    Code:
    MEMORY_MANAGEMENT (1a)
        # Any other values for parameter 1 must be individually examined.
    Arguments:
    Arg1: 0000000000041790, A page table page has been corrupted. On a 64 bit OS, parameter 2
     contains the address of the PFN for the corrupted page table page.
     On a 32 bit OS, parameter 2 contains a pointer to the number of used
     PTEs, and parameter 3 contains the number of used PTEs.
    Arg2: fffffa8005abd150
    Arg3: 000000000000ffff
    Arg4: 0000000000000000
    Or this

    Code:
     
    Use !analyze -v to get detailed debugging information.
    BugCheck 4E, {99, 26322c, 2, 26832b}
    Probably caused by : memory_corruption ( nt!MiBadShareCount+4c )

    I would suggest you run Memtest86+. Run it for 8 complete passes all at the same time. Please use these instructions.

    Please Run Memtest86+

       Information
    Please download from this site only http://www.memtest.org/ in the middle of the page are the Download links, you can download the ISO.zip or the Auto USB Flash Drive installer.zip

    Extract the Zip file. If you chose the ISO image, burn it to a CD using Windows Disk Image Burner or any Image burner you may have. If you downloaded the Auto USB installer, extract it, insert your USB 2.0 Flash Drive and take note of the drive letter. Run the installer, select the Flash Drive Letter, check the format box and press next. It will install memtest86+ to a flash drive. You can use either V4.20 or V5.01. Boot from your selected media. If you use V5.01 it will tell you to press certain buttons at the start, please press no buttons. The test will begin on it's own and continue to run until you stop it. It needs to run for 8 complete passes or until you receive an error. If you receive an error, stop the test. Even 1 error is a fail. Each pass tests a different part of the ram and each of the 10 tests in each pass tests something different. It takes a minimum of 8 passes all run at the same time to completely test the ram, more passes are better. It is quite a long test and will take several hours depending on how much ram you have. Due to the time length it is best to run overnight. If you have any questions, please do not hesitate to ask

    I've attached a photo from right after the start of the process, and from several hours afterwards.
    Please explain the results. I do not understand what this means.

    Thank you.

    In Pass 2 you had 5120 Errors. You have bad Ram or Bad Motherboard. To see which, you need to keep track of which stick and which slot. Then run 1 stick at a time in each Dimm Slot, then do the same with the other sticks. If you see an error, stop the test. If a stick of ram is bad, it will fail in every slot. If the sticks of ram pass in all but 1 slot, then you have a bad Motherboard Dimm Slot. The odds are that the ram is bad, but it is possible the Motherboard is bad. I have been where you are and know what a pain it is. I have also had a few times where it was the motherboard and not the ram.

    Thanks. I will run the memtest program with the sticks in each dimm until I isolate the problem.
    To confirm...as soon as I see a "fail"...then I can stop memtest? There is no need to continue for hours if I see a fail?

    Correct. Even 1 error is a fail. You are lucky. I noticed your first screenshot is 5 minutes. At least that one won't take long. The good sticks will though. But when you see an error, stop the test. But, running a 4 GB stick will be much faster that the 16 GB. 16 GB takes about 20 hours to run 8 passes.

    So I guess we cannot determine which dimm the software started testing first? There's no logical approach it takes?
    And if I pull out 3 and leave one in...do I need to check my mobo manual to insert it in one particular dimm? I guess it doesn't matter as i'm not running the os, just the software?
    Okay...sounds simple enough...just tedious. Thanks for your help. :)

    Trust me, I know what you are saying about tedious. The test should run with 1 Stick in any slot. There is no logic behind which stick is bad or what order it checks the sticks in. This is the only way I know of to do it. On the brighter side, you ram has a lifetime warranty, so you shouldn't have any problem getting it replaced free, except for shipping. I would request to send in all 4 sticks and receive a kit in return. A kit has been tested to all work together, where individual sticks are not. I would also request an advanced replacement. You have to give them a credit card number, but it is not charged as long as the bad ram is returned within the time limit. That protects them, and also keeps you from being without a computer for a few weeks.

    I started testing yesterday, and stopped short of completing everything to see what you think about the results so far.

    I tested each stick of RAM in the same slot...about 1.5 hours each. No errors.

    I tested one stick of RAM for 5 minutes in each of the other three slots. No errors. (i thought that might reveal if the mobo slot was the problem seeing I got errors so quickly the first time)

    I had no more time to test for the day so decided to put all four back in the same slots they were in, and run a test all night. No errors. (see attached screenshot)

    So i'm a bit surprised that I was unable to reproduce the errors I got the first time I had all four sticks in.
    I did notice when I began the tests yesterday, that the tops of the sticks of RAM were not all flush at the top...as if one or more was not seated properly. I did not think much of it at the time because I knew I had a problem before with the RAM not being fully inserted and had resolved that issue. But i'm thinking now I am being too cautious with how hard I push them in. There's a lot of flex as I push.
    So I pushed a little bit harder when reinserting them all last night. They are all flush at the top, and i'm certain they are in properly...and wondering if I should just pause the testing for a week or so and see if I get another BSOD.

    What do you think?

    There was one other thing that happened that might be worth mentioning as well. When I began testing yesterday I received a bios request before the memory software booted up. The message was something about being unable to start because of overclocking...and gave me the option to (F1) go in to the bios settings or (F2) use the defaults. I chose F2.
    I realize that unlike the first time, I only had one stick of ram in, instead of all four...but perhaps this bios setting change is why I got no errors during my second test with all four sticks in at once.

    If either of these are related to the BSOD's...I would think it more likely to be that one of the sticks was not seated properly in the mobo.

    Jeff1961, sure you can try it and see if you have any more BSODs. But, as I stated before, if you run memtest86+ for less than 8 passes, it is not fully tested. Memory can be pretty difficult. No test is 100% accurate, but the test I asked you to run is the best test we have. I don't recall it ever showing errors where there were none, but it can pass ram that is bad occasionally. If the ram was not fully seated or locked into place, that could cause an error. If you continue to have BSODs, you are going to have to spend the time and run the tests right. 8 complete passes or an error, whichever happens first. With 16 GB of ram, 8 passes will take about 20 hours to run, and they all have to be run in one test. I know what an aggravation that is, but there is no way around it. I can't tell you how many times I have been through it and if there was a short cut, trust me, I would be using it.
