Jetway GTX 460 1GB

Anyone OC'd this card?

How did it do? Not much info on the web. There was a review on one site where they were given a card that was clocked to 900Mhz! However, when they looked at the power consumption, it indicated that the voltage had been tweaked, so they didn't think a standard card would get so high an OC.

Cheers.

Download MSI Afterburner from the MSI website (works on any card) and install it then run it then overclock the 460 using it using trial and error, Simples.

For instance my MSI Cyclone will do 875/1750/2200 on 950mv. Just try say 800mhz then slowly increase it and use a game or Furmark to test stability until you get the maximum overclock available. Add voltage (mv) to stabilise any overclock.

Thanks varkanoid. Any tips on how much the voltage should increase by? Do I do it in 5 or 10mv steps or bigger?

do it inthe smallest steps possible, my 295's go from 1037 to 1051 in one step so it may vary from card to card.

Incidentally, what is a normal "safe" amount that you can increase a gpu voltage by? I know it will vary depending on the fabrication process etc, jsut I have never really bothered with voltage tweaking on my gpu before...not that it matters much for me, since im vram/cpu limited most of the time lol.

Okay. Downloaded Afterburner and booted up. It won't allow me to adjust the voltage (nothing showing on the adjuster bar). The other thing is that I can't unlink the core clock and shader clock.
I did a test with the core set at 800MHz, ran Furmark at 1440X900 (my monitors max res) and MSAA X32 and was getting average FPS of 65. GPU temp went to 67C, with the fan on auto going to 40%.
Only ran the test for 10-15 minutes, just to get an idea of FPS and temps.
How long for a proper stability test?

in the settings on afterburner you have to unlock the voltage change option but clicking the button. Likewise you have to press a button to unlink shader/core.

Artifacts/texturing issues should show almost instantly if its bad, if its very very nearly stbale but not quite, it may only be one pixel artifact every now and then, so play a game for a while and see if you notice anything. I would not reccomend crysis for this since it has loads of single pixel lighting through the trees etc,so its very hard to spot actual artifacts.

Generally, if it is ok in Furmark/ATI Tool, then it will be ok though, unless its limitingits clocks in the programbecause of drivers

Great, got the voltage unlocked. However, the link button is not active for the core and shader (guess I can't unlock it).

I only know for the cards Ive used, and I could unlock the shader and core, but it tended to always work best if you set them manually to basically the linked values anyway so I stopped bothering since I wasnt chasing benchmarks and jsut left them linked as it was.
