how do i overclock my 690?

[ish1]

Hi guys.

I like the performance of my gigabyte 690, but i just wanted to see how much extra i can get by overclocking it.

I have never overclocked a graphics cards so i would like some tips on how to do it. What software should i use? and what steps should i take?

Cheers

You need to download EVGA Precision X

Here is a pic of my GTX 690s using it

Set the power target to 135% use this setting all the time

GPU Clock Offset, I would start at about +50 and increase in +10 steps until you see artifacts or the screen freezes/crashes then back off 10 or 20.

Mem Clock Offset, I would start at about +200 and increase in +25 steps again until you see artifacts or the screen freezes/crashes then back off 50 or 100. You may also get decreased performance from the memory as the speed increases (due to error correction) again back off on the memory oc.

Don't forget to increase the fan speed to keep the temps in check.

The settings I am using in the pic above is for running benchmarks, when I game I use stock settings but if I was to overclock the cards for games it would be noticeably less than what I am running above.

Thanks for that

I shall try it and see how i get on.

What does the power target actually do on the card? I am asking this because im running it on boost to 1120mhz 24/7 without increasing the power target.

IIRC it allows the card to draw more power to boost higher.

What some people do is run the power target at 135% even with the clockspeeds at stock which leads to a small but worthwhile boost in performance.

I've got the XSPC razor block on mine. It stays at 1025Mhz with a power target of 135% 24/7. Anything more than that and games spaz out.

Never messed around the memory speed. On the past few cards I've hard it's barely made a difference.

Just tested with power target at stock and 135%

I got a tiny increase in my score on the Heaven 4 bench by using 135% power target but the weird thing was the max boost was actually 13mhz lower on all 4 GPUs than running at stock. I can only think that the extra performance came from the minimums getting boosted higher even though the maximums were lower.
