Im having issues to OC my gtx 460 1gb

post #1 of 7
Thread Starter 
Hey ocn, I want to overclock my evga gtx 460 1gb.
I saw other people getting past 900 core clock.
But even at 845 core clock, I got insane bug spike.
Any idea how I can overclock it without having thoses bugs?
I did a small video to show you guys what kind of bug im talking about



BF3@ultra preset 1080p (I normally play medium preset@1080p)
Quality of the video is compressed for fast upload
Thank you

That pretty much means your card isn't stable if you artifact when overclocked but not at stock settings.

I would up the voltage a bit and see if that fixes it. Also do realize that not every gtx 460 will hit 900+ on the core, some can and others can't, it just matters how good of a chip you got.

Not all cards are created equal.

My old EVGA 460 could clear 900 core at 1055mv, while my later Gigabyte one would start to get mad at me after 850 core no matter how much power I put through it.

It could be.

Can you go to 1.1v and see if the artifacts go away?

If its dropping to 2d clocks like that at 1.087 theres a good chance thats as far as your card goes.
Back off to 840 core and test at 1.062.

Its just the luck of the draw.
Some cards go far, some only go a little way.

My advice is to be happy you are getting what you get out of the card.
Ive had some real lemons in the past, and it helps to be happy even when you get a mediocre one.
