need some advice OCing Gtx 460

post #1 of 3
Thread Starter 
I've been using MSI afterburner to tweak the card and try to OC it but I don't know the proper method for doing so.

Do I just bump up the core, shader and memory clocks and then bump the voltage until stable ? should I worry about not going over a certain speed ?

the card idles at 23C with an ambient of about 20C, so I have some headroom.


Edit: I'm using my Sig Gtx 460, 1gb version

Firstly you want to increase the volts to 1.087v and go up from 800core each time by 10/20 until bsod or 'display driver stopped'

Once you max out your core at those volts then start with the memory clock. As your on stock cooling you might want to think about flashing the card to enable a better fan profile and it also gives the ablity to unlock voltage

Use furmark to check you load temps and run crysis benchmark tool with 50 runs or so to test stability. GPU stress testers are not really a good way of testing stability (only temps) gaming is the ultimate means of testing gpu oc.

Good luck

Come on, you never EVER tell someone who is a first timer to increase the volts blindly.



To the OP:

The safe way, at lease for a first timer is like this:

1. Increase core by 10
2. Run benchmarks (game benchmarks, 3dmark, so one) for 10 minutes.
3. If ok, return to 1
4. If not, increase volts by 0.01
5. go back to 2.

And you continue like this while you are watching the card's temps.
If I'm not mistaken, for the 460, best not go over the 1.09v for 24/7.

Also there is no need to increase memory at all unless you benchmark.
For games, massive OCing of the GPU memory translates to barely 3-4 FPS if any.
