I have been dabbling with overclocking the past couple of weeks and I can get incrediblly high speeds without getting dangerous temperature, as I have my fan set to 100% speed all of the time, but If I even were to rase the voltage level using afterburner without even altering my core or memory speeds crysis 2 seems to freeze alot during loading screens, not to mention the artifacts (which I assume are the giants rocks falling from the sky that seem to deteriorate) which occur when Im not even overclocking while having the game on lowest settings.

Have any of you experienced any of this?

if you're having voltage problems, it's usually from VRM. can you link the exact model of your card please?

I have a pair of 460s and i can usually do 800/1900 at 0.987 and 900/2000 at 1.087 (although this isn't 100 stable due to summer, it should be more stable with winter temperature)

also, besure to raise the voltage slowly and carefully. if you give it excess voltage the GPU may die very quickly; although the upper dangerous ranges are usually BIOS-locked by default.

well idk exactlly that its a voltages problem. only that it causes crysis 2 to freeze alot.

As for the model idk where to get the model # from but its a GTX geforce 460 768mb

He means the manufacturer. I have a Palit Sonic 1gb GTX460 and have it set to auto overclock when Crysis 2 starts. I run 825/1925 with a fan RPM of 65% - I have no problems, I don't bother with voltages. The gains I might get from over-volting would be minimal.

When I ran my gtx 460 at 860 w/ stock volts the video card would consistantlly restart itself during games. But when I upped the voltage the card became much more stable, howver the freezing during loading screens in crysis2 i9ncreased it even crashed a few times. but at the same time I was able to get my card as High at 900 MHZ clock w/ the voltage at 1.082 (i think that's the max that afterburner allows it to go to.

Is the 460 even good for overclocking?

^oh they are excellent. at 900+ MHz 460 1GB should match a stock 470
halo, just don't overclock in multiplayer; too risky.
