Effects of SB OC on single GPU performance (tests at 4.2 and 5.0ghz) - Page 2

post #11 of 45
Try underclocking your CPU, and test it from 3ghz up in 500mhz increments, you'll be able to find the point at which your GPU is actually bottlenecked, then you can run your CPU slightly higher then that to preserve the life of the chip.

The gentleman put work (and plans on putting more) in to the project. We all know that a 2500k is a beastly chip and will chow through any game out there. I'm certain the difference in clock speed is something of interest to a number of people including myself.

I do know for sure that even at 5.3GHz in vantage I could get higher than 40k gpu simply by increasing my cpu speed, because in limited parts there is a cpu bottleneck.


Anyone who doesn't understand why a faster cpu is required to get the most from your gpu(s) is ill-informed and probably is the same type of person who resorts to name calling. However there is always "enough" and you've clearly reached it with your single card, overclock it more, or go SLI.
I've killed 2x 570's in 4 months, this is my second RMA. First one died at 920/2000 1.1v (975mv VID), second at 900/1950 1.038v (950mv VID). I was sick and tired of gaming at 800x600 on my spare card. So I'm gonna hold off on overclocking the GPU for a little bit. This will surely change once I snag Crysis 2, will need to OC this puppy.

maybe you need to understand that SB is not going to be a bottleneck to a single gpu card and overclocking the cpu more is not going to bring better results.

I typically avoid people who make general comments.

I also avoid people who don't think a 2.66GHz i5-750 will bottleneck a single 570.

Let me finish watching top gear and I will prove it, ok?

Sure, detach the monitoring program from afterburner, make it long enough to show several minutes of usage.

Then run vantage, at 2.66GHz and get a 23k or higher gpu score.

I'll be quite surprised if you can maintain 98% usage or more throughout.
