~~The GTX 670 Overclocking Master-Guide~~ - Page 316

post #3151 of 3357
This is going to sound like a really dumb question, but ive been looking at PrecisonX for some time now, and cant figure out how to turn the Kboost on, or what it is.

I just picked up a second 670 and im currently running it in sli, and i ran valley at Extreme HD and got a score of 3932 and wanted to see how i can break the 4k mark. My cpu is only at 4.6 so maybe thats holding me back a little.

But am i just having a slow moment, i cant for the life of my figure out the kboost thing

i can tell you a higher cpu speed wont raise your score. unigine benchmarks are gpu based not cpu. the only way a higher cpu speed would help is if youre bottlenecked. you just need higher gpu core and mem speeds.

as far as k-boost, its there somewhere. maybe i saw it in the voltage pop-up?

the highest stable run i was able to do +35 and +600. Anything higher on air and i was getting artifacts, and the top card which is almost 10deg higher then the lower one was around 75deg. I need to figure that out.

Sorry to ruin this Sean argument, but with +125 core and +810 mem, I am not getting 1 bit of increase in BF4 MP.

I also outperformed a GTX770 on Unigine Heaven Benchmark lol.

I think I am CPU bottlenecked; i5 3570k 4.2Ghz OC.

Thoughts guys?
post #3155 of 3357
3570k shouldn't bottleneck, can you get higher OC, like 4.4 ghz with a new cooler?

And what about your ram?

Hello everyone after having my card for a year i decided to overclock it...

I have been following the Masters Guide but i am stuck on some key areas:


1. When i am using the quick oc guide is k-boost supposed to be on when i am finding out my offset???

2. I am having different scores for the same settings and dont know why when using heaven.

3. After i find instability issues and heaven crashes and i try to go down 5% to where it was stable it continues to crash no matter where i set the offet... even to default so i restart my cpu.

4. Do i keep pwer target and voltage at max all the time even after finding the offset?

5. What do i do after i find my best offsets? with regards to this :

Temporarily increase both the Power Target and Voltage slider to their maximum value. This will minimize the throttling caused by going over the Power Target.


6. Please take a look at my settings smile.gif

K -boost is not recommended it runs gpu at full speeds all the time

Hello I have recently overclocked my graphics card using the GTX 670 overclocking master guide. It works well but I seem to have a issue with the power limit fluctuating a lot. Any reason why that could be? This recording was done using the heavenly benchmark on ultra. any other suggestions would be awesome as well.

Better, I just punched 4.5Ghz stable on my bad boy with 1.301 V and max temp of 82 on Prime95. However, after I apply my GPU OC, I am now getting 10-20 FPS increase. Hell Yeah.
