Heads up on Intel 13th 14th Gen CPUs and DX12

My 14900k thermal throttle in r23 until i set power limit 253W, current limit to either 307A or no greater than 332.75A AND i need to undervolt at the same time. There are a few ways to do this, but i did it by lowering AC_LL to 0.3. If you don’t want to do that, you can instead set svid behaviour to “typical scenario” (which reduces it to 0.4), or you can apply an offset to the core voltage (maybe start with -0.05).

For me, setting pl1/2 to 253W, current limit to 332.75A and AC_LL to 0.3, i get around 38k+ in r23, but temps never go above 89, usually hovering around 80.

If i reduce current limit to 307A, r23 gets around 37k, but temps never go above 80 and hover around 70ish.

In sim, temps never go above 75 with the first option (hovering around 60 to 65), or 73 set the second (hovering around 55 to 60).

Setting current limit to 356/400A, i can get around 39k/40k in r23, but i get occasional spikes into 90C+ and throttling for a few seconds.

If i remove all limits and just let the bios run wild, i can get around 40k score in r23, but it’s at 100C instantly and constantly throttles.

So for me, 332.75A is probably the sweet spot, unless ambient temp stars to increase in summer, when 307A might be better.

Another thing to remember is that a lot of the time, when people are posting 40k+ scores, they’ll be using custom loop, or liquid metal, de-lidding, and all kinds of exotic stuff like that, and that they also probably run in safe mode and close down every possible program and service to ensure maximum score. Mine are just with the pc booting up normally, after everything has started (e.g. steam/ discord running etc).

But yeah, with 13th and 14th gen, they do run hot and it’s normal behaviour for them to boost until they get too hot and then throttle…so you’re probably better off ensuring they are power/current throttling, rather than thermal throttling.
