Is overclocking safe with modern hardware? Could an overclock and/or an associated overvoltage cause physical damage to hardware, when talking about 20% increments? I don't know many other implications than overheating and instability.My video card does the same (nVidia 8800GTX, expecting to buy a more recent one soon).My BIOS has a temperature guard that automatically shuts the system off (Crosshair 2 Formula), applied to CPU and chipset.doubling the clock of the CPU), but I'd go by successive steps. Let's first say that I'm not expecting to hard overclock a computer (ie. My question may seem dumb, but, really, I want to think about it objectively. Answers without enough detail may be edited or deleted. There would be a good chance you could fry the GPU before the thermal throttling or voltage regulator could kick in.Īs long as you overclock sensibly, you won’t damage anything, least of all your motherboard.Want to improve this post? Provide detailed answers to this question, including citations and an explanation of why your answer is correct. The only time you would damage a card overclocking would be if you ramped up all the settings to maximum before testing it first. In fact it is actually quite difficult to damage any of your hardware if you overclock sensibly, and in increments. These safeguards, thermal throttling and voltage regulation protect the GPU and the motherboard from damage when overclocking. Unfortunately that second or two is enough to fry a card if you’re not careful. The problem is that is can only really guard against it once it detects too much voltage going through it, so it is still possible to overload a card, albeit only for a second or two. It is also a guard against users trying to force too much voltage to a particular component, in this case, through the PCI-E port to the card. If a component or peripheral draws more power than the threshold allows, the motherboard will cut it off. If a GPU core needs 5.71V, the regulators need to ensure that the voltage supplied is 5.71V. It ensures that the voltage that is sent from the PSU is delivered at exactly the voltage the components need. To protect itself from damage, the motherboard has voltage regulators built onto it to ensure that the power supplied to the video card is supplied at a steady rate. Once this balance has been reached, it is a good idea to just leave things alone and enjoy the new faster machine. This allows you to find a happy medium between speed, temperature and reliability. The extra power drawn will be minute, often as little as. When overclocking, it is generally wise to increase the clock speeds in small increments. That would be the thermal throttles at work.
There must be sufficient cooling available to allow the extra heat to be dispersed, otherwise the system will shut down to protect itself. This is the main consideration with overclocking. The faster something works, moves or calculates, the more heat is produced. The by-product of computer processing is heat. The motherboard and power supply must have the capability of supplying the increased power for the overclock to work. To get more power, it will have to draw more from the motherboard, which in turn draws more from the power supply. To run faster, the card will need more power. The GPU core speed, or clock, and the graphics memory speed are the elements that can be increased to overclock the card. Overclocking a PCI-E bus carries higher risk for less reward than other overclocking options, so it generally isn’t done. The GPU core speed, the graphics memory speed and the type of connection it has with the motherboard. The speed of a GPU is limited by three things. So, Can Overclocking a Video Card Damage the Motherboard? The short answer is no. The advent of thermal throttling for CPU and GPU architectures means that the components will usually shut themselves down before allowing themselves to overheat too much. Overclocking is much safer now too, which also adds to its allure.
It used to take some creative tweaking to get a CPU or GPU to overclock, now many manufacturers will supply them open to overclocking, or even already overclocked!
Now it is much more mainstream thanks to manufacturers relaxing a bit and allowing a bit more freedom with their hardware. Overclocking used to be a pastime for geeks or extreme gamers.
