    I've found that Prime95 will sometimes run error free for over 10 hours for one or two of the tests, but fail the third test, sometimes only after 8 - 12 hours. If your system isn't stable, you run the risk of file corruption. A 14 hour Blend test is similar to running the small and large FFT tests for 7 hours each.
    • The Small FFT test primarily stresses the cpu with very little memory testing.
    • The Large FFT test heavily stresses the memory sub-system.

    I'm comfortable with running Prime95 Blend for 12 - 14 hours, followed by HCI Memtest for at least 8 -12 hours.
    As stated earlier, IBT or Linx are good for short preliminary stress testing only, and their GFlops scores are a good indication that your system performance is in the ballpark.

    Click on the Prime95 tutorial link in my signature for more information.

    just my 2 cents
    Well I ran 10 passes of IBT on max to get the initial stable state.

    So far Blend test is running fine for 8 hours, I will let it finish 10 hours before I move on.

    I'm at work and connected to my PC remotely, I can run HCI after I finish 10 hours blend...

    What do you think?

    EDIT

    Wow, can't believe this happened, but Prime95 failed after 9 hours! How's that possible?!?!?!

    Anyway, this is the last successful test in the results file:

    [Mon Jun 18 09:26:30 2012]
    Self-test 2048K passed!
    Self-test 2048K passed!
    Self-test 2048K passed!
    Self-test 2048K passed!

    I don't know which one it failed on since I wasn't looking at the monitor, I think there was a BSOD.

    Jim, since you freaked me out about file corruption, I turned the PC off for now.
    How to proceed from here?

    Thumbs up Re: Z77A-GD65 + i5 2500K Overclocking - How to start?

    I think, therefore I am, I think.
    Your stress testing is progressing nicely.
    If the HCI Memtest has no errors, there's one more stability test that isn't well known:
    Winzip or 7zip
    1. Create a single zip archive with a large mix of file sizes where the total file size before zipping is about 8 - 10GB or more.
      Use a lot of small and medium sized files!!
      Be creative, use all files in folders from My Documents, your Downloads folder, Program Files, etc. to make testing easier.
      It's OK to use a few large ISO files as part of this test.
    2. Test the archive integrity after you've created the large zip archive.
    3. Unzip all the files to a temporary folder.
    4. There should not be any errors during this test.

    Some have reported that their systems passed the standard stress tests, but failed the zip/integrity/unzip test.
    If there are any errors, your system isn't stable.
    If you are into gaming, play your most demanding game for several hours.
    It's a tough job, but someone's got to do it.

    Wait, before I move on to HCI and other tests, what does it mean if P95 failed the Blend test after 9 hours? Don't I need to get P95 stable before I move on to other testing methods?

    *sigh* :/

    Does your Prime95 log list the last FFT size(s) and/or workers that failed.
    The windows Event Viewer should have information that points to the application that failed.
    Event Viewer might have some warning or error messages that could help diagnose the cause of a BSOD or lockup/freeze.

    Do you have temperature logging enabled to see if there were any temperature anomalies?
    Is your system set so that it won't auto re-boot when a BSOD occurs?
    If auto reboot is set, there should still be a BSOD log entry that can probably help with diagnosing the problem.

    You might want to run an extended HCI Memtest to see if it reports any errors, where it will keep on running and report all errors that occur during the test.
    If you have regular backups for all disk partitions, most data corruption can be fixed by restoring backed up files from the time of the most recent backup for the affected file or folder. You might loose some files that were created or modified after the most recent backup.

    All the stress testing in the world can't guarantee that a system is 100% stable.
    If you repeat the same Prime95 Blend test, it might run without errors for 24 hours, or it might fail even sooner.
    It's a good sign that your system ran for 9+ hours, it's just not good enough.

    It shouldn't make any difference whether you run Prime95 or HCI Memtest first.
    If I were stress testing your system, I would now run HCI Memtest first, for 10+ hours, followed by Prime95 Small FFT for 10+ hours and then Prime95 Large FFT for at least 8 - 10+ hours.

    If you make any bios changes before your next test, run IBT or LinX first, using the maximum amount of memory for 5 - 10 loops.
    Don't run IBT or LinX for a longer period of time. They can sometimes find errors quicker, but they are not as effective as Prime95, HCI Memtest, OCCP or Orthos.

    Ok, to answer your questions:

    Does your Prime95 log list the last FFT size(s) and/or workers that failed?
    Results.txt file showed the last successful test

    [Mon Jun 18 09:26:30 2012]
    Self-test 2048K passed!
    Self-test 2048K passed!
    Self-test 2048K passed!
    Self-test 2048K passed!

    The windows Event Viewer should have information that points to the application that failed.
    Event Viewer might have some warning or error messages that could help diagnose the cause of a BSOD or lockup/freeze.
    I turned the PC off after the BSOD, the system restarted itself, will this info still be available next time I turn on the PC? And if so, where?

    Do you have temperature logging enabled to see if there were any temperature anomalies?
    Is your system set so that it won't auto re-boot when a BSOD occurs?
    If auto reboot is set, there should still be a BSOD log entry that can probably help with diagnosing the problem.
    I was watching the screen with TeamViewer just before it failed, temps were at 65-70C max load so I doubt that there was a 95C spike all of a sudden after it had been stable all night long
    Yes, the system is set to automatically reset after a BSOD, I suddenly saw that TeamViewer disconnected and when I reconnected it said that Windows recovered from an unexpected error, always displays this message after a BSOD.
    Where can I find the BSOD log entry?

    You might want to run an extended HCI Memtest to see if it reports any errors, where it will keep on running and report all errors that occur during the test.
    If you have regular backups for all disk partitions, most data corruption can be fixed by restoring backed up files from the time of the most recent backup for the affected file or folder. You might loose some files that were created or modified after the most recent backup.
    I don't have any backups atm, just my OS on the main C drive and games/movies/apps on the other drives, I assume that at worst case scenario, only Operating System files are corrupted and stuff like games and movies stay fine, right? As a last resort I can always format and reinstall Windows... but I don't think I'll have to do that.

    All the stress testing in the world can't guarantee that a system is 100% stable.
    If you repeat the same Prime95 Blend test, it might run without errors for 24 hours, or it might fail even sooner.
    It's a good sign that your system ran for 9+ hours, it's just not good enough.
    True, but then again, I'd like to be able to run Prime again for at least 10 hours of Blend without an error.

    It shouldn't make any difference whether you run Prime95 or HCI Memtest first.
    If I were stress testing your system, I would now run HCI Memtest first, for 10+ hours, followed by Prime95 Small FFT for 10+ hours and then Prime95 Large FFT for at least 8 - 10+ hours.
    How about running Memtest for 10 hours overnight and then another 10 of Prime blend? Would that suffice? I'm never around the PC for so many hours so I won't be able to monitor 2 tests of Small/Large FFT 10 hours each along a 10 hours Memtest run...

    Thanks

    A Prime95 small FFT error generally points to a problem with cpu settings or voltages.
    A Prime95 large FFT error generally points to a problem with memory settings or voltages.

    The following is the beginning of my most recent Prime95 log entries from the results.txt file in my Prime95 program folder:

    Windows BSOD/Error Debugging
    Administrative Tools --> Event Viewer will get you started.
    Press F1 for HELP when the Event Viewer is open for more information.
    You can use the options in the left column to look at Windows Logs, Applications and Services, etc.
    A web search using: windows event viewer guide OR tutorial should provide more information.
    Use common sense with Event Viewer and you should be able to find error application or system log entries that occurred shortly before your system re-booted.

    Bug Check Code Reference (Windows Debuggers) is a good starting point once you find the BSOD code.
    Windows 7 Forums is a good starting point.
    Crashes and Debugging - Windows 7 Forums is where you can a learn about BSOD/crash/freeze basic debugging.

    Some people consider there system stable if it doesn't crash and don't do any stress testing.
    Others are satisfied if a stress test doesn't have errors after a single 1 - 3 hour test.
    It's your call how long you run stress tests and how many tests you run.

    Is extended stress testing a PITA? YOU BETCHA!!!
    I did my time, payed my dues and haven't done any extended stress testing for about two years.
    We can make suggestions, you need to provide the time and effort required for your comfort level.

    You don't have to run all recommended tests consecutively.
    Run HCI Memtest and Prime95 Blend for now (order doesn't matter) and follow up with additional extended stress test at your leisure if that's what you want to do. I'd feel reasonably confident with these two initial tests, along with the large zip /test integrity /unzip procedure, but I would perform additional stress tests before I felt "completely" comforable.

    I think 20 loops of IBT on Maximum stress, 8-10 Memtest and then another 8-10 blend plus the Zip test should deem the system stable.

    My last successful FFT was 2048K, so the one after that failsed which one is it, large or small?

    I'd like to try again with a little more juice to the memory, I think I'll raise S/A one notch towards 0.965 and retest IBT 10 loops, Prime95 blend and if these 2 pass without issues, I'll move on to Memtest.

    Will update soon, thanks for the help :)

    In my Prime95 Blend results file, after the first FFT test, the pattern is:
    2 different small FFT tests
    2 different large FFT tests
    2 different small FFT tests
    2 different large FFT tests
    etc.

    This pattern is with the older v25.11 x64, non-AVX Prime95 version.
    If you want to open a can of worms, in your MSI forum thread, ask for their recommended stress testing procedures.

    I don't know if 2048K is the largest FFT size when Blend testing with the default program settings.

    Default Re: Z77A-GD65 + i5 2500K Overclocking - How to start?

    Mmmm well one of the head honchos there told me that he considers the system stable after running only IBT since it's the most stressful test, but I just proved that the system can pass 20 IBT loops and still fail P95 after 9 hours :) So I still want to do Prime.

    I'll up the S/A voltage since it's memory related, run IBT for 10 loops with maximum stress and then move on to Blend for another 10 hours or so.

    If all goes well, I'll try HCI.

    Side question: I intend to go forward to 4.8 which will be my final frequency since my Vcore is getting close to 1.4, should I continue stress testing on 4.6 or move on to say 4.7 and take it from there?

    Also, turns out I'm also using the non-AVX of P95, I've been testing with 25.11 64bit which is non AVX! Will download 27.3 when I get home and test it.

    Any special guidelines on how to use P95 AVX? Thanks

    From my observation Prime95 has a fixed set of tests that it will repeat for all 3 tests. The FFT sisez vary according to the FFT size range but repeat itself for each test.

    After 10 hiurs I believe they should already repeat at 4.6GHz (or even less).

    Search Prime95's log back to 2048K and see what came after when it pass before, that's the FFT size that failed.
