Unfortunately, some separately purchasable hardware components seem to be optimized completely for gamers these days (overclocking mainboards, RGB on GPUs, etc.). I'd rather run everything at 90% and get very big power savings and still have pretty stellar performance. I do this with my ThinkStation with Core Ultra 265K now - I set the P-State maximum performance percentage to 90%. Under load it runs almost 20 degrees Celsius cooler. Single core is 8% slower, multicore 4.9%. Well worth the trade-off for me. (Yes, I know that there are exceptions.)

> Unfortunately, some separately purchasable hardware components seem to be optimized completely for gamers these days It turned out during the shitcoin craze and then AI craze that hardcore gamers, aka boomers with a lot of time and retirement money on their hands and early millennials working in big tech building giant-ass man caves, are a sizeable demographic with very deep pockets. The wide masses however, they gotta live with the scraps that remain after the AI bros and hardcore gamers have had their pick.

I’ve had multiple systems that crash or corrupt data when underclocked, so running at 90% might not be what you want. You can always play with the CPU governor / disable high power states. That should be well-tested.

  It sounds like you are conflating undervolting for underclocking. Undervolting runs it out of spec, while underclocking simply runs it slower

  Setting a P-State max percentage is completely reliable/stable, it will clock lower on average to hit the lower performance target. It’s kinda similar to setting a powersave governor, but more granular. I think you are confusing with undervolting.

    No. For giggles, set your DRAM frequency (MT/sec) to something crazy low, then try using the machine for a week.
