i9-14900 mitigation settings

[pnoelw]

Good morning

I’ve just purchased a new computer with an Intel i9-14900 CPU on an ASUS Rog Maximus Z790 Dark Hero motherboard and a Corsair ICUE Link Titan 360 RX CPU Cooler.

The computer isn’t for gaming but will be performing extended, high-volume FFT computations which drive my current i7-8700 at 100%. I have set the max processor speed on the i7 to 3900MHz to maintain a reasonable temperature – no more than 87C.

I am very aware of the recent voltage and degradation issues associated with the 14th gen i9 CPUs. If I understand correctly, this problem has been rectified through updated BIOS (and microcode?).

What should I be doing to ensure that I mitigate risk when the i9-14900 chip is working hard?

• What should I be checking for in the BIOS?
• And what settings should I make in BIOS?
• Should I make any changes to the Windows power profile? Windows 11 Pro
• Are there any Intel or other tools I should install to monitor and/or control voltages and temperature?

I note that the max.turbo frequency of the i9-14900 is 5.8GHz. I’m not averse to restricting that to a lesser frequency if necessary.

Thank you

Noel.

With ASUS motherboards the usual update procedure is to first install the latest drivers in Windows.

These include the chipset driver, Management Engine (ME) driver and Serial IO driver and should be installed in that order. The latest BIOS update (and included microcode update) will also install the most recent version of the ME firmware.

Select BIOS defaults once the new BIOS has been installed. The BIOS defaults will mean that XMP is set to Disabled, Enable it if required. In the BIOS AI Tweaker section under Performance Preferences the normal setting is Intel Default Settings. This is an inter-related group of settings including for example the Intel default defaults values for PL1, PL2 and iccMax. This should help to keep CPU temperatures at a minimum.

Just to confirm - the drivers (chipset, ME and serial IO) and BIOS updates are accessed via the MyASUS app and not through Windows update. And BIOS settings would be accessed through the Advanced Startup process or is there an app to do that also?

The ASUS drivers and BIOS download pages can be accessed directly from here . As you say Windows update does not supply these updates for a desktop board.

Booting into the BIOS, just restarting the PC and pressing the Del key a few times works for me.
