680 won't go past 705mHz GPU core, even though it's overclocked far past that

post #1 of 6
Thread Starter 
I've been Folding a lot recently, so I figured I'd OC my 680 to get some more PPD. However, after passing some stability tests, such as Furmark Burn In, Unigine Heaven Benchmark, and such, I noticed that it was not running at the frequency it was supposed to be.

I had these OCs quite recently perfectly stable, passing the same tests, and being able to Fold 24/7 without a hiccup, but after a fresh install of Windows, to cut out all of the crap I had before (mainly a Linux user, but need Windows for GPU Folding), I haven't seen the card go past 705mHz once, which is even below stock clocks!

Here, in Furmark, it is running fine at the 705mHz GPU core that it shouldn't be.



What Precision X has to say about it.



I have the the 320.49 drivers installed, and a fresh copy of Windows. What could the issue be?

Go to options and enable K-Boost. This locks the card to full stock/overclock clocks no matter what the situation. Porn? Max clocks. Youtube? Max Clocks, etc.

Err... Think it goes to 700 ish MHz when it notices that the current boost clock isn't stable, that's what it did for a friend of mine anyways, try lowering your boost clock offset a bit and see if it manages to stay "boosted". (Remember to reboot before)

Well, Kboost is running it at 1200mHz GPU core. That is better than 705mHz, but I still want the 1400mHz that I had just a month ago, completely stable!

Have you enabled k-boost and then raised it to 1400Mhz manually and clicked apply? Or are you just expecting it to go there by itself sort of thing? Give it a try and see if it sticks.

I had that problem on my 670, means the OC is unstable so the card clocks down to 700 in my case was 750. To be honest its the last time I will be buying Nvidia has long has they have this System, My 670 is by far the most annoying Card I ever had to OC, It took me a day or 2 to find the a stable clock then I updated my drivers and had to start all over again. Good Luck
