My rule of thumb is to never overclock a computer you use for anything important. If you keep photos on it, if you use it for your banking, if you use it for work/homework... never, ever, ever overclock it. The 4-5% speedup you might get is not worth the risks. Finding out that an important file has been silently corrupted by an unstable overclock is a horrible feeling.

Let me put it this way.
Every computer I ever overclocked died within 6 months.

Is skydiving safe?

No, not really.

Do I want to do it again?

Hell yes.

Sounds like you didn't do it very well, then. :P I've run my desktops overclocked since...forever. No CPU failures, just two dead motherboards after years of abuse.

Depends on your definition of "safe", how mild/extreme of an overclock you are talking about, how good your cooling is, and whether the system is being used for anything important. In other words, "it depends".

Overclocking will reduce the lifespan of your CPU. Let's say your CPU could run for 40 years with default settings. You OC just a little and reduce it to 35 years. OC a lot and it will last for five years. Is that long enough? Depends on your situation really.

Of course as someone mentioned before it could die sooner so if you get a CPU that will last for five years with default settings and you OC that one a lot it will die pretty soon.

Just like with everything else quality varies within products. A safe bet is when your CPU is getting slow and you want to upgrade then you overclock. You don't have a lot to lose at that point.

As to how, well you do it usually in the BIOS. I've done it but I am certainly not a master or anything so I should let someone else explain it.

my current overclocked system is almost exactly 6 years old and still running almost as fast as it was back then

Counterexample: my old Sandy Bridge i5-2500K ran OC'd every day for six years before I retired it, and that on the stock cooler.

Is it safe? No. You have to know what you are doing.

How to do it? Read up on an overclocking guide for your specific type of CPU/GPU. In addition, you will have to plan for the increased power and heat you will need to deal with.

Is it worth it? Yes. I have an i5 2500K and an AMD 7950 that have been substantially overclocked for years, and they are working just fine. (I recently had to turn down the OC on the 2500K a scootch though as it was no longer stable, it's still happy running at 4.4)

General rule of thumb: As long as you're not increasing voltage, overclocking is "safe" and relatively simple. Keep in mind that most mobos supply auto voltage, so if you OC, your mobo will likely increase the voltage automatically. You'll have to make BIOS adjustments to counteract/prevent this.

Google Search : "[Insert CPU model here] stock voltage overclock"

There are certain generations of CPUs that were notorious for unexpected failures from just slightly more voltage than stock. For example the 130nm Northwoods often suffered from "Sudden Northwood Death Syndrome" above 1.7v--which is only 10% higher than the stock voltage of 1.55v. The 45nm chips also tended to degrade after prolonged use at high voltage, dropping in maximum stable overclocks over time until even the stock speed required massive overvoltage to be stable (Intel even retroactively lowered the Vmax ratings). And there are many current reports of 22nm Haswells with their FIVR degrading as well. In between those were generations of chips with a reputation for near indestructability, and of course even with the suspect ones there are plenty of people who had no problems with their particular sample. So there is risk in a statistical sense but if you are reasonable it should be low.

One of the few positive things Microsoft's telemetry for Windows 8 and 10 (and backported to Win 7 to preclude it being a reason for avoiding the free* upgrade) has provided for consumers is the realization that even when running at the stock speeds, PCs are not entirely stable and have a quantifiable error rate. I always wondered why I always ended up with lower overclocks requiring more voltage and heat than other people. Turns out I just have less tolerance for instability than they did, and still cringe every time I hear about someone undervolting their stuff to reduce heat, or overclocking without raising voltages. It's not as stable as you think.

If you have money to burn put together some tweaking purpose system to experiment with cpu/gpu overclocking ideally, and compete in a few of the major benchmarks. Not a production system. Overclocking has some thrill and Adrenalin into it for sure. Sure it has potential hazard's but I generally feel its an acceptable risk in moderation. Like keeping the cpu/gpu overclock to the highest boost frequency.

IMO, it's quite safe, provided you don't go nuts with the voltage. Providing good cooling is also a good idea.
My longest running OC is my current browser computer. It's an AMD 1045T six core phenom running at 3.3GHz base and ~3.6 turbo. It's been running this way for about 6 years w/o any stability issues whatsoever. The 3.3 is achievable with bone stock voltage, and the turbo speed needs only another 0.05v over this level. After that, the frequency vs voltage curve get a bit crazy. The chip will do 4 gig, but only with scary voltage.

In this case, you're still within the stock/turbo frequencies of the highest clocked official version of the Thuban core (the 1100T, at 3.3/3.7). So as long as it's stable and temps are reasonable, I'd expect it to live long and prosper. :lol:

The Phenom and Phenom II cores were tough mofos. Back in the day I accidentally ran a Phenom 9550 fanless for a while (fan died and I didn't notice). It got really toasty, but never skipped a beat.

Been a running an overclocked 4790K and GTX 970 for three years with no issues... I'll build a new system within the next two years...
