This is necessary to understand the performance drop-off from the undervolt. Software with single-threaded and multi-threaded benchmarks.Monitoring software for temperature, CPU clock, voltage, and power reading.What You Will Needīefore we can start this guide, there are a few things you need to have ready: And if you do face instability, you can always reset back to defaults. Note that lower voltage may cause system instability (crashes, stutters, or freezes), but it will not damage the CPU. However, undervolting is safer than overclocking as it lessens the pressure on the CPU. Messing with a CPU’s energy consumption in BIOS can be intimidating for many. Here’s a video from Optimum Tech explaining the benefits and safety of undervolting: So, undervolting for small-form-factor cases, laptops, or console-like devices can be extremely useful. In some cases, the core clock frequency can be reduced for even lower power consumption. This is done by lowering voltage requirements while maintaining the same CPU speeds. To get that temperature sweet spot, users can undervolt their CPUs. High power draw brings a couple of disadvantages: it reduces the CPU’s lifespan, increases heat output, and leads to higher electricity bills.
For example, tasks like gaming or rendering require a lot of processing, so the CPU starts drawing considerably more power.ĭepending on the CPU model, strenuous tasks can lead to a power draw of up to 300W, while basic online browsing can be around 50W or less. Anyway, will overclock it from BIOS.Before we get on with the steps to undervolting a processor, it’s best that we first explain how it works and its benefits.ĬPUs use different amounts of power based on the task they are working on. buy yourself a cheap ssd and put your OS on it before you start to turn your 2 minute boot time into 25 sec boot time that will helpĪlready have a Samsung 850 EVO 120 GB SSD and Windows 8.1 is loaded into it.
but anyone who is serious about cpu overclocking is going to tell you the same things. why are you trying to deviate?īecause don't want to restart PC multiple times. and if thats the case, you have the chance to mess up your hardware. like cpu speed, nb and sb voltage, cpu voltage. too many variables for software to control reliably. the bios/mobo is your primary controller of hardware, and when a software comes in and tries to take over, things do really translate very cleanly. From what i understand, its not very reliable.
