Vista 64 Asus P5Q BSOD'S

  1. Hi guys, need help to find out what is causing my random but frequent system crashes.


    E6750 @ 3.2ghz
    4x1 Gig Corsair xm2 @ 800mhz
    800w psu
    24 inch widescreen
    3x150gig raid 0
    Vista 64
    Latest Bios

    I keep getting memory management errors and page fault in non paged area. These can happen during playing a game, or when windows loads up. I did run a brief memtest on some of my ram, but it found no errors. I am wondering if the crashes could be as a result of a driver on the system or something. I have 5 logs for you.

    EDIT, just added a 6th dump file. This bsod was irq less or equal or something.

    Classic signs of a RAM problem. Check to see if the RAM requires extra voltage. CAS 4 @ 800mhz requires extra voltage.

    Oh really, that's interesting. Looking at the ram itself it says 1.90v, the motherboard was and is set to auto. I presumed that was 1.80, anyway for a while i have been running it at 1.90. Maybe i should up it to 1.95 or even 2.0 then? So it may not be faulty ram, but not enough volts?

    BTW, here are some finer details about the ram itself.

    Corsair xms 2 CM2X1024-6400 1.90V Ver 5.2.

    Thanks for your help peter. :)

    EDIT, oh actually how do i find out if i have Cas 4 or 5? I think it might be 5 but not sure.

    EDIT again, actually i think it is 4.

    Hello again. Today i got a new bsod that i have never seen before.

    Since implementing your previous suggestions the bsod's went away, but then this morning after booting into vista 64 i got this one.

    I've just finished an OC session and I can confirm a truckload of different BSODs on my P5N32-E SLi Plus and ALL due to bad voltages.
    I actually have my E6600 @ 3.2GHz ATM just like your CPU.

    I can see your CPU is OCed (from 2.66). Have you tried putting everything back to stock? (inluding voltages)
    Also, it could be a good idea to tell us your current voltages. If you've added them manually, then you know where to look at.
    If you've let them to Auto, you should have some kind of monitoring page in your BIOS. It should show your current voltages so just post them back here.

    About the RAM, please google for CPU-Z, run it (no need to install it) and go to the SPD tab and tell us what it says in the timings table:

    Hi there, thanks for the reply. I have not tried putting everything back to stock yet. It could be voltage problem, but this cpu has always been able to handle up to 3.2 on stock volts, or at least it did on my older motherboard, asus p5w dh deluxe. All volts are left to auto currently, except mem which is at 1.90.

    When i played call of duty world at war zombie mode i often find the game running at 60-90 fps, but every now and then the game will freeze for a second or two, sometimes more, then it goes back to normal. I have noticed vpu recover errors which i think is causing this, however maybe its volts not sure. I have tried 4 different drivers, all the same result.

    My pc recently came back from repair, with this new motherboard, and apparently passed all tests.

    The memory bsod's seem to have gone for the moment.

    I will reboot now and write down the voltages under monitoring, then i will get cpu-z and pst back asap (10 minutes).

    Ok, here are the volts from bios.

    cpu 1.408
    3.3v 3.296
    5v 4.944
    12v 12.488




    I actually have 4 gigs of ram, but i think 1 stick was dodgy so i removed it, i will be getting some same model same brand ram tomorrow, but it will ve 2x2gig ddr2 corsair xms2 800mhz.

    I was referring to all the volts! 1.2v HT, NB, SB, VTT.

    Those volts you've posted seem to suggest you have a pretty good PSU so that shouldn't be your issue.

    Forgot to add, what are your idle and load temps?
    I also suggest you use FurMark for GPU testing and ORTHOS for RAM and CPU stability tests.
    Both are free, small, easy to use and don't need to be installed.

    And about your RAM, set it for 5-5-5-15, Cmd rate to T2, tRC set to auto, voltage @ 1.850V, 800Mhz. Also, for 4 DIMMs it's often required to have a slightly higher NB voltage (say, +0.50 to the default one, but no more than 1.60).

    Still waiting on my new ram, once it arrives i will post back with updates. :)

    Ok Update.

    Got my new ram, no crashes, not one. Stable at 3.5ghz and 871mhz ram. No more bsod's. Loving it.

    However got another problem. Keep getting atidkmag has stopped responding but has restarted successfully messages during intensive 3d gaming. Tried 4 different driver versions and it still happens. Think i could have a dodgy card. Have checked the temps on it, and they are fine. Seems to be a common problem though which led me to believe it could be software related, i dunno.
