Adjust voltage for 10900K using Maximus XIII HERO board
Adjust voltage for 10900K using Maximus XIII HERO board
I've already disabled MCE, but the CPU still gets hot. I’m using a Maximus XIII Hero board—any other settings I can adjust to cool it down? Even without MCE it’s drawing over 125W in games. When I run Cinebench it stays around 4.9GHz until the end, then drops. It’s using about 1.35–1.36V. Should I try Undervolt or further reduce power? I’m not familiar with OC and how to safely lower voltage.
Adjust the core clock multiplier in your BIOS to a lower value instead of reducing the voltage. If that doesn’t work, consider a more effective cooling method.
No one should lower the voltage unnecessarily, but for an Intel 10-core processor it significantly impacts power use and heat generation. These results demonstrate this effect. @gh0st47 On an Asus board, you can adjust the BIOS to Offset Mode and apply a negative voltage. For example, setting a -75 mV offset works well. Running a 10900K at a 49x multiplier should reliably bring the voltage down to 1.25 V or less during Cinebench tests. When tweaking BIOS settings, monitor the VCore reading in HWiNFO64. The standard voltage table Intel provides is often too high, which helps ensure long-term stability. This additional voltage may become necessary in 10 to 20 years, but it’s unnecessary today.
I saw the stock options in "settings" for my i9-10900KF on the Z590 Gigabyte board. Under heavy load at 4.9ghz it runs around 1.34v, which often causes the TVB to lower to 4.8ghz. That was quite intense. With my overclock I’m at 5.1ghz with 10 cores running at 1.28v during full load—much cooler than stock and still higher than normal. Stock configurations tend to be too aggressive on both Intel and AMD systems. The same applies to the GPU; I lowered its voltage, cut power use a lot, and kept 99% of its performance. On my Vega 64, undervolting helped boost speed. Manufacturers add extra voltage to guarantee stability across all samples. You can experiment yourself to find your limits—usually you’ll surpass them unless you’re using the poorest tests.
