Can overvolting cause instability?

post #1 of 5
Thread Starter 
For example using much more voltage than you actually need causes failed to boots, bsods, freezes etc. In either situation the load temps are very safe.

Im talking particularly about the Q6600 chip

You can up the voltage. Know what the manufacturers spec is. Try to keep it within spec or a touch higher. You will risk the CPU if the voltage is too high, regardless of temps. You should also know the manufacturer's spec for maximum temperature.

of course it can!
Also not enough voltage can be a problem. Also some CPU's have more tolerance for higher voltages. you may pass them but the higher the voltage the hotter it will run and that can put a stress on the CPU in which it may and will reduce it's lifespan.

that's why you start by overclocking little by little until you don't get a boot. go back to the working OC and then stress test in on windows to see how stable it was. Generally to get an idea of how to further OC it. once you found an Oc that you're comfortable with you will test it with prime 95 orthos and several other apps to make sure that it is stable. if it BSOD anytime you will have to go back in to the BIOS to to change some settings till you get a good 24hr+ without a BSOD

Yes, too high voltage can cause instability as well.
But it's seldom to happen.
The best thing when overclocking and overvolting is to use lowest possible stable voltage. Oh, yeah. Higher voltage will make the chip degrade faster.

Personally, I would avoid overvolting CPU (with exception Pentium class CPU because it's cheap). It will make the CPU hot and lose it's energy efficiency.

on last thing i will suggest.
TO be on the safe side, Use a different (less important) boot drive. there's a slight risk of a bad OC corrupting your OS
