Need help for stable overclocking MSI GTX 460 Hawk

I am facing problems when overclocking my GPU.

1. When I turn ON and try to increase the GPU core voltage, the settings get back to default and does not remain saved. This issue was for all the voltages though I have unlocked the voltage settings.

2. When clock my card to 850 Mhz with default voltages I have observed that Crysis 3 crash after 4-5 mins of gameplay.

3. After clocking the GPU to 820Mhz Crysis 3 runs smooth but I see Artifacts when heavy explosions occurs. The overclock was stable but Artifacts

On default voltages, How much I can overlock my GPU?? and what makes my voltage settings go default again even on changing them.

All ppl with MSI GTX 460 Hawk, plz give me your settings for overclocking the GPU stable at least at 880 Mhz.

Thank you!!

Can you clarify a bit "settings going back to default". Afterburner?

2. When clock my card to 850 Mhz with default voltages I have observed that Crysis 3 crash after 4-5 mins of gameplay.

Means your card/system can not play Crysis 3 at 850 MHz at default voltage. Either excess heat, or low voltage, or both.

3. After clocking the GPU to 820Mhz Crysis 3 runs smooth but I see Artifacts when heavy explosions occurs. The overclock was stable but Artifacts

Means your GPU need more juice. Push voltage up a bit.

On default voltages, How much I can overlock my GPU?? and what makes my voltage settings go default again even on changing them.

This is the part I don't understand. WHEN does this happen?
From what I hear, you are pretty much maxed at 780 MHz on default voltage. At least in Crysis 3. Try 800 MHz

I have Talon Attack version which is same as your card, except default clocks are 811M Hz / 975 MHz, and RAM chips are higher rated (0.4ns). I have no problem with Afterburner overvolting, but undervolting does not work well, so for these purposes I am using Nvidia Inspector, and AB for monitoring.

I have done benchmarks @ 950 MHz with voltage unlocked Afterburner (+150mV, and even +200mV),
but for everyday gaming I am usually running at default clocks under-volted to 0.975 V (from default 1.012 V),
occasionally pushing it at 850-870 MHz (1.037-1.062V). I just don't like excess heat for 2-5% higher framerates. Memory overclocking, I mostly don't even bother with.

Bottom line: For 880 MHz Crysis 3 stable, you need to step up on voltage slider till 880 MHz is stable (perhaps coupled with better airflow/cooling, which in turn will allow these voltages to become usable for extended periods of time).
How much voltage you need, only practice can tell. I need +70mV.

I modded the BIOS to max out the voltage on my MSI GTX 460 but it was a "Cyclone" model. I hit 950mhz stable on the core at max voltage. The card did burn out eventually but my wife spilled miso soup on it so I don't actually know what killed it.

I have 2 eVGA GTX 460 1GB SLI overclocked to a modest 827/1654/4100 using a miniscule
1.000 volts. Turn it down a notch to where I have mine and everything should be O.K.

Give it a shot.

sorry, I forgot to mention Afterburner.

When I change voltage settings in afterburner then the voltage settings go back to default when I restart the afterburner. This should bot suppose to happen as this settings does not even remain saved when I change voltage and save the settings.

Heating is not problems, my card stays below 70c even on load. I have managed to run Crysis 3 with 820 Mhz but like I said I see some artefacts when explosions occur in game.

I am trying to clock it to max 880 Mhz, for this I need specific settings for afterburner. Plz also mention the steps.

I don't think a 100 Mhz increment over the factory clocked GPU will raise any complications. I just able to need a perfect voltage tweak and manage to save them correctly.

obviously the miso soup killed it coz these GPU's specially MSI made does not burn out below 1000Mhz if cooling is not an issue.

I tried the same method but as I said the voltages does not remain saved and turn back to normal when saved and relaunched the afterburner.

Bottom left in afterburner, click apply overclocking with windows startup. It will stay overclocked. Not all cards clock the same. Over volting can and will eventually degrade a pc component, how long it takes depends on the weakest component .

Why the PC needs to reboot when I save overclocked settings?? Can you give any specific settings for GTX 460 Hawk to keep it stable at 850 or 880 Mhz??
