Overclockng fails

[Allshevski]

Hi, how are you?

 

I've been trying to get into GPU overclocking for some time now and finally found some time to do this. However, I'm a complete newbie when it comes to these things. I followed almost any tutorial on the internet, read topics on this forum but every time I apply settings my PC just freezes for 2 seconds, screen flashes black and gets back with a message which says that GPU driver stopped working but recovered, two TDR error messages and one that FurMark has stopped working. Also, when I rebooted my PC, I could run some programs but then when I clicked on desktop, entire screen went black, then clicked again and it turned white. (what the hell?) after a while showed a message that Microsoft Windows has stopped working. only my mouse cursor was visible and was behaving like nothing happened (when I hovered it over a field where was text, it turned to this text one) Then everything went back to normal. Tried increasing the voltage as one man told me to, but I don't know how much I should push it. Any ideas? My temperatures were good (max. 80 ℃) all the time.

 

Without any overclock, I get avg of 68 FPS on default FurMark settings. 

 

GPU is GTX 960 [GV-N960WF2OC-4GD]

OS: WIndows 10 Home, latest version

All drivers are up to date.

RAM is not faulty.

 

Tried on:

135% power limit

+140 MHz on core clock

+200 MHz on memory clock

[+75 mV core voltage - only when first tests failed]

Ask me for more information.

Lower core voltage and core clock and go up slowly.

Okay. By how much? Is there any good rule of thumb for voltage and clock values ratio?

Voltage you're never really going to damage your GPU as it's tiny increments so maybe leave that at full.

But with the core clock start at 50 and go up by 10. You'll get a nice stable overclock in no time.

After each 10MHz leave for a few minutes.

Once at a speed that you're happy with leave to ensure stability for I'd say 30 Minutes on Furmark.

Okay. And then slowly go down with voltage and power limit until it crashes or leave it as it is?

By the way - now went from 130 to 140, and currently I'm running at 150 Mhz offset on core clock for a few minutes and still didn't crash! I have to be more patient if I want to overclock anything..

And that 68 to 74 FPS on FurMark is soo awesome ^^ not really... but hey, it works!

 

Edit: no longer. Can't get it over 140 Mhz.. damn..
