Been using an aorus z690 pro with my 14900k. Been really stable even using the instant 6ghz feature. Reasonable price as well for the features vs performance. However if you plan on any sort of overclocking I would rather recommend msi. From all the guides/videos I’ve gone through, theres barely any help with aorus/gigabyte. Aorus Default settings also have unlimited power/voltage and has been difficult for me to undervolt stably. Where it seems like msi just has a lite load mode with like 20 profiles for varying degrees of performance which I personally would prefer instead of manually fiddling with voltages for hours on end and still getting some random crash while opening a web browser

Massive difference when playing at 1440p with up to 60fps increase in some games.

So this sounds more like unstable voltages, as I would experience this when trying to undervolt or overclock without adjusting voltages accordingly. I would advise to not only set bios to defaults, but also ensure you have things like multi core enhancement disabled which might be turned on be default. Also enable turbo limits as intel por/default 253w. If you see improvements with this, it might at least rule out you having a faulty cpu/pins

I don’t understand, I get people want their views and up votes but this is a link to a video, where they have said they got that feedback from intel which could of been a random marketing person/bot response.

I don’t see this as intel confirmation until they do a press release from the actual company

When you say instability what does that entail? Clock speeds, temps, power fluctuations, software being unresponsive could all fall under that. Asking as I’ve been running the 14900k with a z690 aorus pro for weeks now with massively varied setups, with xtu ai limits at 450w, bios limits at 253w. With undervolting the even pushing all core to 6.2ghz. Ive put it through 400w load benches and undervolted till it crashed and it keeps chugging along

Don’t interfere with settings without knowing what they’re for. Default settings are generally best option unless you know what you’re doing or trying to achieve

Check on your mobo support page what version has the micro code update that enables being able to identify 14th Gen. This way you can tell before getting the board instead of trial and error like other comments

Ensure the bios version you updated to included an update for the microcode values in that or previous revisions. Without this it will not have support for the 14th Gen. Technically doesn’t know 14th gen exists without it

I also recently updated from a 12700k to a 14900k on a aorus z690 board. I only noticed it when going into XTU that power limits were too high even in stock bios settings. Using 330w at stock clocks of 5.7ghz all core in cinebench. I found that along with disabling MCE, I also needed to set the turbo power limits to Intel POR. This now correctly does power limiting to 253w but I still get 5.7ghz all core.

I think the default auto settings on the z series boards seem to ignore the limits in favor of having stability/compatibility with all performance levels of cpu.
