GTX 670 Weird Problem

Hello All.

I just build my first gaming rig a couple of days ago and noticed a problem today.
I have a GTX 670 FTW GPU at 1006 MHZ Clock speed. But I noticed in my games it does not reach that speed. In GTA IV it reaches about 700, To make matters worse on another game it's 400 MHZ. Is it the driver? or a faulty card..
Temps do not seem to be an issus as it's about 25C at idle, At full load i'm not sure but when I run games it's around 50.
Thanks,

  1. Have you updated all drivers ?
  2. You mean up to date drivers? Yes I have the most updated one.
  3. I would post a 3DMark11 results, But it keeps crashing on Physic's test
    (cpu and gpu both not OC'd
  4. I think it's very possible your card is messed up does it do that in all the games you own
  5. both the downclocking and crashing in physX testing sounds like a driver issue.

    make sure you have the latest drivers from nvidia

    uninstall the driver(s)/software in Control Panel\All Control Panel Items\Programs and Features

    then for added benefit reboot into safe mode and run driver fusion.

    then reboot to install the latest drivers.

    also temporarily turn off windows update. it will download and install it's nvidia driver after you uninstall what you have now and before you install the latest. turn it back on after you're done.


    now this just maybe a start or it can be a final solution - but its best to make sure.
  6. It does do it to all games. But another problem I have is that 3DMark11 crashes on the CPU test, I haven't even overclocked anything!
  7. What CPU do you have? It could very well be that it's bottlenecking.
  8. Yes I have the lastest driver 306.97.

    But when I first booted up my PC, My wireless adapter did not work on win7. So I installed the driver from the CD that came with the GPU. Then I plugged my PC in the basement and connected it wired, then downloaded the latest driver from the site. I have not deleted that yet. So do you want me to uninstall both drivers and then re install?
  9. My cpu is the i5-3570k No OC

    +1 try this if it does not work you have a faulty card. :(
  11. The good news is if you do have a faulty card evga will make things right.I would of bought my cards from them had they not used reference cooling that was a no go for me.
  12. So I.
    Turn off windows upate
    Uninstall the drivers.
    Download driver fusion
    Reboot system in safe mode and run driver fusion.
    Reboot again.
    Re-downloaded drivers
    Turn on windows updates?
  13. Anyone?
  14. Did you do what looniam mentioned ? If so and still nothing your card has issues.I would rma right away.
  15. No not yet. I did try K-boost and it fixed the problem. But shoulden't the card run at 1006 by default?
    EDIT: With K-boost it still crashes on 3DMark11
  16. I never was interested in that card so i might be wrong i believe it's suppose to be overclocked from reference 915MHz to 1006MHz, while the memory is up from reference 1502MHz to 1552MHz (6208MHz effectively).
  17. Yes the EVGA FTW is OC'd 1006 HMz
  18. o.k. that is what i thought but was not sure.
  19. To my eailr post do I do this in this order :

    Turn off windows upate
    Uninstall the drivers.
    Download driver fusion
    Reboot system in safe mode and run driver fusion.
    Reboot again.
    Re-downloaded drivers
    Turn on windows updates?
  20. Yes try it now i am not sure it's going to fix the issue but it's worth trying before rma
  21. I fixed the problem! I went into nvdia control panel and changed all my games power options to "maximum performance".
