GTX 460M Overclocking

What do you mean? max possible? how do I know that?

You can't know what is the maximum overclock you can apply to your GPU. Only testing will determine that. Start from the stock clocks and increase them by bumps of 20-25MHz until either the card gets too hot or you start seeing flickering, artifacts or bsods. Every card will overclock to different levels. The cards are guaranteed to run stable at stock clocks but they can usually go higher.

Not everyone can push their cards as high as some people here. Just because reaper can do 850/1500/1700 it doesn't mean that you'll be able to. On the other hand, the possibility that you can go higher exists as well.

If you want to know the reason, search for what binning in electronic manufacturing means.

You want to run it longer than a few seconds at each level.
Start with stock to get a baseline then up it by 50MHz, run through a benchmark or game demo (something to keep it occupied) and look for massive heat changes or defects.

I prefer at LEAST one full 3dmark or similarly long benchmark that runs automatically.

Your first couple jumps can be larger (50MHz), but after then use the smaller ones.

Ease up the settings to find the maximum setting it will run at, then run it at the setting which works a few times to make sure all is well. If anything (even the smallest detail) seems wrong, ease it down. A STABLE OC is better than bragging rights.

I often find that just that one step back results in the best balance of speed and stability and a longterm OC.

As mentioned, once you find the stable OC, push it to that when you game.

Well, max meaning the highest you can go without crashes/artifacts/other random none normal stuff. So far 460m seems to do pretty good at hitting 850mhz on core, and chastity has hit 874mhz, so anywhere in that range will most likely be your max as well. However, there is NEVER a guarantee, each GPU is different, so you very well could only hit 775mhz, or 800, or just whatever the luck draws.

Either way, overclocking isnt really difficult, just watch the temps, and everything should be fine, I even just leave HWMonitor as a startup program so it's constantly running and I can every now and then check up on it to see how my temps look.

So for G53SW-XN1 usally, what is the best settings for OC?(850mhz on core and bla bla bla...)
Or every card with his own max?(750Mhz on one, 900Mhz on the other...)

[tijo]

Every card has it's own max. However, there usually is an average value that most cards can attain. It seems to be 850 for th 460m like it was 800MHz on the 5870 core.

[WaffleBoy]

So I can do steps every 25-50Mhz with each option till the games crash and bla bla bla... right? and if the temp' good(OC), it should be fine (the GPU) right>?

[tijo]

Yes!

A reminder... nothing is 100% sure.
You might be the unlucky guy whose 460m just won't work above stock.

Also, no one can tell you 100% that your GPU will survive even 1MHz higher than stock.

Note, I say this only to urge caution and not to deter you.

Do the reading, do the careful work, and enjoy the rewards. :-)

Most of the dead OC'ing attempts are due to people who rush their OC just for bragging rights.
