Motherboard round-ups, embracing 1.38 V to 1.40 V in more recent pieces ![]() You've seen us use 1.35 V for the overclocking tests in older One of our processors when it was set to only1.38 V. Voltage instability on a particularly cheap motherboard fried Same processors die a fairly slow death at voltage levels between 1.40 VĪnd 1.45 V (somewhere between weeks and months on our test benches).Īnd we're expecting more than a year of reliable service from the parts Levels beyond 1.45 V at above-ambient temperatures can kill an Intel CPUĮtched at 32 nm (Sandy Bridge-based parts included) very quickly. We've learned through trial, error, and dead processors that voltage In equipment, we always make our recommendations to you erring on the When it comes to protecting hundreds of dollars Increases in electromigration resistance usually require drastic The problem with blaming heat alone on a failure is that moderate Reducing the number of electrons that are forced through the closed Insulation capabilities of transistor gates in the “off” phase, The blame for a fried processor or GPU solely on heat, ignoring theįorce causes electromigration, and colder silicon more easily resists And yet, many technology enthusiasts place Insulators or conductors depending on charge state and are particularly While the full description of this phenomenon is complex, it’sĮasy to understand that an insulator contaminated with conductive Where material is physically transferred from one part of a circuit toĪnother. Our overclocking articles often mention a process called electromigration” Toms Hardware had a great write up on this in their Man Vs Machine Automatic Overclocking Article. These auto-overclocking features, while they sound great on paper, tend to supply more voltage then is necessary and can damage your CPU if your not careful. Its also a good idea to cross-reference your CPU on the technical specifications at CPU-World which is a very reliable resource of processor information as sometimes the AMD product Pages is sometimes missing information on certain models.ĭO NOT USE THE AUTO-OVERCLOCKING FEATURE OF YOUR MOTHERBOARD BIOS OR SOFTWARE. The AMD Product Pages will give you the same information concerning AMD processors. The Intel Ark will give you all the relevant information concerning any Intel processor. This is the single most important thing to understand before you begin overclocking, messing with the multiplier, or changing and adjusting the CPU Vcore(Voltage).įirst thing to do is find out the max temp and recommended voltage levels for the CPU you are planning to overclock. Use Aftermarket cooling heat sinks of sufficient TDP or water cooling to ensure best chance of not having premature hardware failure.īefore we get started, lets talk about voltage. Do not Overclock on the stock AMD or Intel CPU Heatsink and fans. Please remember to back up your computer before attempting ![]() You are solely responsible for any damage to your CPU or other hardware due to user error, inadequate cooling, too high of voltages, and any other factors. If you choose to overclock, you do so at your own risk. Disclaimer: I am not responsible for anything that may happen to your PC when overclocking.
