Weird Overclocking !

Recommended Posts

Naveen

Hi guys i am having a weird overclocking problem

i have got a weird setting here...

i tried to raise the OC value to 600/740...

before that i download FurMark ( a nice little 1.5Mb tool to render a image .. with nice FPS rating...

when i tried to set the shader clock value beyond 1000-1100Mhz the core clock speed goes to 100 MHz ( this is while running FurMark + RivaTuner Hardware Monitor )

the setting dont get changed while i tried to change in the Rivatuner system setting...

why does the core value reverts back to 100 Mhz when i try to Oc shader clock more than 1000 Mhz ??/

here is the screenshot ...

i have marked the value at various setting...

but if i/we can resolve the core clock speed not to get reverted back to 100Mhz .. i think i can gain still more performance...

I think it is because your video card is reaching the temperature threashold, they different from each machine, but when it reaches that point, it downclocks the video card for safety reasons. nvidia intergrated this in their newer drivers after the 16x.xx series.

Yes this is true, but I believe this downclocking mechanism was incorporated into previous drivers as well (since the 100.xx series). Checking your (gpu) temperatures is a vital thing to do when overclocking. It can also give you needed insight into your problem.

cozz i dont want to go to a old driver ...and how to know which is the safe limit they have setup..

I don't get downclocking for the following drivers: 178.13,178.15 and 176.44 - whql which i'm currently using. I recommend you try using one of those. I get downclocking if i use any other 170xxx series drivers.

I also do recommend you try the 178.13 as they may resolve this problem. Tell us if the problem persists.
