Overclocking

Overclocking is what it says, you run your processor at a higher "speed" then the limit that was set when it was built. I'm not into overclocking, I'm too scared of the computer dying or something, even if I know a shitton of people do it every day without any problems. Aaaand your computer seems like it's 1000x better then mine anyway, what do you need overclocking for? :P

Typically you can overclock about 10% of the core's base speed safely no matter what computer you have. After that you need to make sure you have a good cooling system

I'm certainly not an expert, but I know a thing or two about OC (I'm writing this on a pc running Intel Q9400 2.6@3.2GHz), but I certainly would not OC a laptop, since laptop is about portability and OC (usually) means increasing voltage go get more power, and this would mean higher battery drain. Anyway, it seems powerful enough not to need any OC atm nor in the near future, so...yeah, enjoy what you have :)

There's always a risk, and it depends on the hardware and the laptop itself, I have a Lenovo y500 too, but with a single GT 650m card, I've overclocked it at about +15% and everything went smooth, but that's about as much as it's safe to do, more than that it's just too risky, Lenovo built the computer that way for a reason.

You should be fine gaming without overclocking anyway, these Y500's are really awesome laptop's, and yours is even better with 2 750, overclock in a year or so.

Never ever overclock a laptop. They have really inadequate cooling, and overclocking places more load on the CPU, which means more heat. Anyway, that's a pretty decent rig, and you really have no need to OC it and risk your investment.

I wouldn't recommend overclocking a laptop, especially if you're new at it.

I wouldn't overclock a laptop, the heat is already too much to my taste. You could try a little overclock on the videocards though, keeping the temperatues under control with GPU-Z or RealTemp.

I've overclocked my processor (3.3GHz>4GHz), my video card (+95MHz graphics clock, 350MHz memory clock) and my monitor(60>75Hz). And it runs great.

This is like your 7th or 8th thread about that damn Lenovo laptop. I'm sorry, but I'm getting sick of it.

Nothing good will come in overclocking a laptop. They're not exactly made with the intention of adding increased heat on top of it. There's a reason they make aftermarket coolers for desktops for those who want to try their hand in OC'ing. But laptop components get hot already, I would advise against it.

I am using a desktop computer with a HD 7950 card, can overclock well above 1100 MHz on core, but the temps get higher and you really need an efficient cooling system (an aftermarket cooler is recommended for decent overclocking). For that reason I mostly run at stock speeds and it's already great enough. If not, your laptop will overheat (especially because the components are packed together with little ventilation). Your laptop already has 2 GPUs and a good enough processor, so you wouldn't really need to overclock as most of the time it's a less than 5 FPS increase (depends on the game though), and this isn't really worth the extra heat and power your laptop is going to consume. You definitely need to monitor the temps real time or risk damaging your precious laptop. Just my 2 cents

I would not recommending oc'ing a laptop until the warranty has run out, unless you have a warranty that covers Overclocking problems.
