![]() So, if you created an offset of 0.1 V, for example, and the processor typically requires 1.25 V to deliver a certain speed, 1.35 V would actually be supplied. The voltage would still vary based on requirements, but the range would be boosted by whatever step you configured. Offset Mode works by adding (or subtracting, if you wished to underclock) a set amount of power to the standard voltage that the processor would use. Thinking about power consumption, Manual Mode is quite inefficient, but gives you the most control. Whether your CPU is idle or running at full tilt, the same voltage will be applied. Manual Mode sets a single, static voltage level. Scroll down to CPU Core/Cache Voltage and click the drop-down menu. Your motherboard handles this behind the scenes but, should you wish, you can set manual voltage levels to support your overclocking efforts. Faster operating speeds require additional power for stability. The voltage applied to your CPU varies continually. We’ll synchronize speeds across all cores in this guide, but feel free to play with individual core settings if required.īefore we make any changes to the base clock frequency or CPU ratios, there’s an additional element to consider: voltage. Select Per Core and you can target each core individually. ![]() Any value you type here is applied across all four cores. Sync All Cores enables the 1-Core Ratio Limit setting. With the CPU Core Ratio set to anything other than Auto, the Core Ratio Limit settings become editable. But, dial back the settings on individual cores and you may achieve a better balance. Why? Applying the same ambitious overclocking profile to all processor cores may make your PC unstable. Some motherboards allow you to target individual processor cores or apply one setting across all cores. Hold fire for now, though.īelow, you’ll see CPU Core Ratio, which allows us to adjust the multiplier. You can now type a value into the BCLK Frequency field. ![]() In the Asus Extreme Tweaker menu, we switch the Ai Overclock Tuner from Auto to Manual, which allows access to the base clock frequency setting. Modern motherboards can be equipped with a raft of automated settings designed to make overclocking easy. A ratio of 42x with the same 100MHz base clock speed would deliver a CPU frequency of 4,200MHz, or 4.2GHz. To overclock the CPU, we can adjust the base clock frequency or the ratio/multiplier to achieve a faster CPU frequency. In this example, 100MHz x 40 equals 4,000MHz (4GHz). ![]() Your processor speed is a simple calculation of the base clock speed multiplied by the ratio. Underneath that, you’ll see a Ratio setting (often known as the multiplier). On the right of the screen, there are two additional settings to mention: BCLK is the base clock frequency, currently set to 100MHz. MSI motherboards even have a physical OC Genie button you can press to turbocharge your PC.Ĭlick F7 to switch to Advanced Mode, which is where we’ll be spending most of our time in this guide (see below). If these manual steps seem a little tough, then check out the likes of Asus Dual Intelligent Processors 5, Gigabyte EasyTune, AMD’s Ryzen Master, or Intel’s Extreme Tuning Utility. However, some motherboard manufacturers offer convenient apps that attempt to safely overclock your CPU for you. We’re about to get hands-on with a motherboard’s UEFI BIOS software, which allows fine-tuning of your hardware settings. I recently upgraded my gaming rig with the NZXT Kraken X62 which pumps coolant over the CPU via a sealed system, then extracts the heat via a large radiator and double-fan assembly, mounted in the top of the case. Consider upgrading to a better-performing air cooler (such as those from Noctua) or investigate all-in-one liquid coolers, which work much like a car’s radiator. Budget CPU coolers (the stock heatsink-and-fan assembly that ships with many processors) are going to struggle here. ![]()
