Q6600 Overclock Seems To Cause 3DMark06 To Crash

I overclocked my Q6600 to 3.0 Ghz and had problems so I just backed it down to 2.75 and all was well until I tried to run 3DMark06 at a 1680 x 1050 resolution with anti-aliasing at 8. I had my 8800 GTS video card overclocked to 675 core and 1020 memory so I thought that might be the problem. But after I underclocked my cpu back to stock 3DMark worked even with the overclocked vid card. The problem I get is my comp crashes with a big blue screen with this text appearing in the top left corner:

*** Hardware Malfunction

Call your hardware vendor for support

*** The system has halted ***

The thing is that I can run normally with my CPU modestly overclocked to 2.75 but I really wanna use 3DMark06 with it overclocked. Any help would be greatly appreciated!

More about q6600 overclock 3dmark06 crash
  1. It would help if you list your complete specs including your PSU model.
  2. More voltage required.
  3. Did you forget to bump up vcore while ocing that cpu?
    Also, stress with Prime95 for at least a few hours. It's not good to find out about instability while actually using your PC.

  4. Q6600 at 2.75Ghz dont need a voltage increase. i think its his vid card OC is not stable.
  5. is that the new 512MB GTS? or is that the old 320/640MB 8800GTS?
  6. and don't forget memtest86+ to really test those rams you got, some 12 hours without errors is usually good enough.
  7. OP i think its best for all of use if you post 3X CPU-Z screenie showing the 1st,3rd,4th page.

    good luck.

    oh and GPU-Z as well!!!:)

    A 3G OC on a Q6600 shouldn't need more voltage. I have mine at 3G and I lowered my Vcore from a VID (stock Vcore) of 1.3 to 1.275.

    I guess no specs.

    Did you lock the PCIe to 100-105. If you locked it to 100, then try 101.
  9. Vcore and VID are two totally different things
  10. PSU is a Silverstone 680 Watt Zeus Model

    Crucial Ballistix Memory is 2 1GB sticks that are running at 667 (standard for this memory) when my CPU is overclocked to 3.0 Ghz (Sync Mode)

    MOBO is a P5N-E SLi I believe 650i chipset?

    And I left voltage at auto cause like other people have said: an overclock up to 2.75 shouldn't be enough to do so. my VID is 1.3250 And I have a vdroop of about .1 V if i remember correctly

    Also, I can run 3DMark06 with my vid card overclocked but with the CPU at stock. So i'm doubting it's the video card.

    If it's 650i, then it's the motherboard bottlenecking. Nothing you can do except getting a new one.
  12. are you sure? Nonetheless I was thinking of buying another mobo, but in a while since I just dropped another $160 on my comp about 5 mins ago :P I was suspecting it could be the motherboard, if so what would you guys recommend for an SLI system (although it doesn't HAVE to be, but it would be nice, if you could refer me to both sli and non-sli q6600 overclockers that would be great).
  13. Just run stock.

    What?

    VID is the Vcore that is chosen by Intel and, I believe, saved in the MSR. That's why I said VID instead of stock Vcore.

    From Intel's site.
    Quote:
    VID Voltage Range: The voltage range set by the VID signals as a reference to the VR output voltage to be delivered to the processor Vcc pins.


    I'll go back and add (stock Vcore) for you. Feel better?
  15. Someone answer why my VID changes in Core Temp? It's low on idle, but when I use Firefox or open iTunes the VID gets higher.

    ROFL... :na:

    VID can't possibly change. It's probably just a glitch in Core Temp.

    Ummm, I'm in the overclocking forums and like I said I was looking for new mobos anyways sooo....
  18. they need to update core temp. bad vid readings for e4600.
  19. Are you sure you don't mean voltage in CPU-Z?
  20. starwars120, did you lock the PCIe to 100?

    I would OC to 3G and run Prime 95 for an hour or so and boot to memtest86+ and test the RAM. Do this to see if it is the OC alone or how the OC is affecting the card.

    Those SLI mobos don't seem to be as stable as the P35/P45 mobos.
  21. Zorg said:

    It can't be. CPUZ only shows current vcore, not VID. He specifically said VID.
  22. Well I haven't ever seen the VID change in Core Temp so I'm assuming that he got them mixed up. I believe it is stored in the MSR.

    Dagger, put the dagger away. :lol:
  23. Yeah, it's VID from Core Temp, Real Temp changes sometimes too. CPU-Z Vcore changes as well, but that's normal. Lupi told me it's going to be fixed with next Core Temp update.

    Yeah PCIe is at 100Mhz last I checked. And as for Memtest I can just make an iso image right? No floppy disk on me anymore :(
  25. Download Ultimate Boot CD it has memtest86+ and some other HD wiping tools etc. You will need to burn the ISO to CD with ISO Recorder v 2 or other ISO burning software.
  26. the CPU should survive on that mobo OC above 3Ghz. its the grapgics

    the vid change is because the speedstep and C1E feature on the mobo that underclocks the CPU to a lower speed and applied lower voltage.

    I believe that the VID is stored in the MSR (Model Specific Register) and doesn't change. It's read from the MSR by Core Temp etc.
  28. you cant change VID but it does change in coretemp if C1E or speedstep is enable in BIOS.

    i think you should read my post again.
  29. Turn off all your power saving features. You never want the system screwing with your voltages when overclocking.
  30. Ok overclocked to 3.0ghz and tested with prime95 no problem, burning disk now and will try using memtest.
  31. memtest went by just fine, gonna try 3DMark06 at 3.0 Ghz with vid card at stock
  32. well, turns out I'm pretty sure it was just the dual monitors I had that was screwing with it. 3DMark06 Worked fine when I set it to single monitors with both the CPU and GPU overclocked. Thanks for all the help guys. Let's hope it stays fixed *fingers crossed*
  33. It should be good, but how long did you run prime95 small ffts?
  34. I ran it for an hour but tonight I might just go ahead and run the small ffts till morning because after I saw 3DMark06 go alright I feel like it should be ok now that I got it all sorted out.
  35. what are the load temp?
  36. load temps hit 57 max

    Ok I took an in depth look at this and ran some tests. According to Unclewebb whether or not the VID changes may be dependent on the mobo.

    All tests were performed on a GA-P35-DQ6 with a Q6600.

    Anyway, here is the situation as far as I can tell. The CPU has multiple VIDs depending on what power state it's in. It appears that the reporting of Core Temp and Real Temp will show the lower VIDs only if EIST is enabled in the BIOS and one of the power saving choices is selected in the power settings in control panel. The CPU clock needs to be at stock and Vcore on auto. Otherwise the VID won't change with the load. If you are using C1E only, you will see the VID max, it won't change with load.

    I got the feeling from reading the posts by Unclewebb that he didn't consider it broken. The posts I read were a little older so maybe he changed his mind, I don't know. It's not a problem as long as you know that you need to disable EIST to get VID max, a.k.a. the VID that everyone should be quoting and probably aren't.

    Ah, wrong guy, you said Core Temp not Real Temp.

    As I said the tests I did were on a DQ6 but I suspect other mobos are similar. If anyone has other results, feel free to post them.

    Happy to see you got it worked out. I didn't see anywhere that you mentioned the little tidbit about the dual monitors. You probably would have gotten ten posts to turn that off in the beginning.
  39. did the OP prime/orthos test his system when OC'd to 2.75 or w/e it was?
