GTX 670

Hello lads,
I just finished playing Black Ops and I'm sad, because when I join a match and play a bit, I get a freeze. My guess it would be the display driver stopped working problem, but I don't really know. I OCed my card to - core clock +165, memory clock +180;
My core voltage is set to +0, should I set it a bit higher?
PSU - 630W
Any advice?
Thanks in advance!

  1. Is it only when playing COD? Definitely set your voltage up no question, you're trying to run overclocked speeds at stock voltage, it'll definitely crash.
  2. what?

    you can overclock and still run perfetly fine on stock voltages...
    you can and oviously will need to increase voltages if you want to overclock as high as possible, but there is no doubt you can get a decent oc of 1200 stock voltages. Ive heard people hit 1300 on stock.

    Did you stress test your gpu? Ive heard where gpu's even stress tested are fine but in some programs they need to be reduced a bit(20-50mhz) in order to run. That could be the issue.
  3. Without knowing which card and which PSU you have, I'd be hard pressed to give any advice about overclocking. But the latest nVidia driver (306.23) has eliminated loads of "stopped working" issues.
  4. Overclocking using stock voltage on Kepler GPUs is very efficient! I'd recommend reducing the core clock by 10-15Mhz and the memory clock by 5-10Mhz rather than increasing the voltage. This should give you stable overclock at stock voltage.

    It seems that the Kepler GPU performs more efficiently with a moderate OC, if you do not increase the voltage, as all its power saving features and boost clock functions kick in at default voltage values. I noticed this when monitoring the max voltage in GPU-z before and after OC. I discovered that somehow it gave the same max voltage readings (i.e. 1.1750V). So, it manages to boost itself @stock just as much as @+100mV.

    I'm saying this as I've been playing around with my 660ti at stock voltage and +100mV and have noticed strange results in 3DMark11 & Dirt 3. The results show that my 660Ti's boost features at stock voltage make my OC much more effective than my manual +100mV OC.

    MSi 660Ti PE/OC @Stock Voltage Stock Clocks
    3DMark11 GPU Score: 9144
    Dirt 3 Avg FPS: 170
    Max Voltage GPU-z: 1.1500v

    MSi 660Ti PE/OC @Stock Voltage Core:+50Mhz Mem:+295
    3DMark11 GPU Score: 9688
    Dirt 3 Avg FPS: 172
    Max Voltage GPU-z: 1.1750v
    (Note: Dirt 3 Crashes right after benchmark! -- so i dont use OC)

    MSi 660Ti PE/OC @Stock +100mV Core:+110Mhz Mem:+485
    3DMark11 GPU Score: 9730
    Dirt 3 Avg FPS:176
    Max Voltage: 1.1750v


    I don't know how, but as you can see, my Stock Voltage OC 3DMark score is just under my Max OC score.
  5. Best answer Try this tutorial, it goes over EVERYTHING needed for GTX 670 overclocking, and takes into account that each chip is different.
  6. Thanks for responses!
    My PSU model is: Thermaltake Smart 630W
    GPU: Asus DCII (non TOP)
    I will soon try decreasing the core and memory clocks!
    But what about Zotac 670 AMP! Edition? It is overclocked to a very high level. Shouldn't my card do it? It's still the same GPU...
  7. Your card should overclock but it's not the same card as the TOP allot get confused and think it is but it's not the top uses specially higher binned chip then the non top other than that there pretty much the same nevertheless you should still be able to overclock that card very well.
  8. Thanks, but one more question: how much should I increase voltage if I want to (+x)?
    What is the safest voltage offset?
  9. Ok thank You all!
