There’s a brand new MSI motherboard BIOS accessible that lets customers flip off present tour safety (CEP) for non-Ok Intel CPUs. What does that imply? Nicely, it implies that anybody that’s utilizing a non-Ok Intel CPU can now save energy and cut back the warmth of their system with out efficiency taking a nosedive.
Whereas this replace doesn’t at present have an effect on any of the chips on our greatest gaming CPU information, customers of the likes of the Intel Core i5 14600 – the non-overclockable model of the Intel Core i5 14600K – have confronted an issue in the event that they discovered their system was working hotter or utilizing extra energy than they want.
With Ok-series chips, the person might simply flip down the AC load line voltage on the chip and its energy consumption and warmth would correspondingly flip down, with efficiency solely barely being lowered, as long as CEP was disabled. Nevertheless, for non-Ok chips, there has by no means been the flexibility to show off CEP, and attempting to simply flip down the voltage with CEP enabled might see efficiency tank. It’s this situation that the CEP replace addresses.
MSI examined this situation by itself boards, exhibiting that if a person reduces the the voltage by half on the 14900K, 14900, and 14700 CPUs, efficiency plummets when CEP is enabled. Nevertheless, with the brand new BIOS utilized, and with CEP disabled, efficiency on all three chips hardly drops in any respect, regardless of CPU temperatures dropping from 100°C to 67°C on the 14900 and from 88°C to 63°C on the 14700. As such, if a person have been to run a 14900 at such a lowered voltage, disabling CEP by way of the brand new BIOS might unlock a 98% efficiency enchancment.
MSI does level out that lowering the voltage equipped to a CPU can cut back system stability so there’s nonetheless some danger on this course of. Nevertheless, in most cases, you need to be capable of discover a level the place warmth and energy are lowered with out your system turning into unstable.
As to how this works, CEP is a system that kicks in to guard the CPU from inadequate voltage, however for some purpose, it hammers efficiency when the AC load line voltage is lowered. Intel has thus enabled the flexibility for these chips to change off CEP, with MSI including this replace to its newest BIOS releases. Assist will fluctuate from board to board, so that you’ll need to examine the particular BIOS releases in your MSI board.
There’s a very good likelihood we are able to additionally count on this alteration to roll out to different motherboard producers too however don’t have affirmation but. Within the meantime, you possibly can see our present high picks for motherboards in our greatest gaming motherboard information.
