Could not configure the power limit for the Z490 Aorus Elite AC.
Could not configure the power limit for the Z490 Aorus Elite AC.
I don't remember if it was at the base frequency or lower. It seems the power output of 89W matches the TDP-down figure of 95W. Are some mobos/manufacturers using clamp-on designs and does Gigabyte differ? This is the first time I've encountered this situation.
I haven't tried enough motherboards yet to confirm. Lowering the TDP doesn't appear to reduce the power ceiling on my Asus board. The standard turbo limits still apply. To check TDP-down, I turn off Turbo Boost and observe the multiplier. The 10850K uses a default 36 base multiplier. In TDP-down mode it falls to 33. Slower CPU speeds cut power use, which seems to be the reason for the lower TDP limit.
After some testing, the Vcore stays around 1.26V when the system runs at the standard power cap of 198W, but falls to 1.18V with a steady load of 168W. Auto voltage adjustment works.
Added to a 11700k yesterday and now experimenting with power management features. It appears to handle the load well—currently capping at around 166W. Compared to the 10600k, I haven’t pushed it lower yet, possibly indicating a threshold where issues emerge. I’m also testing AVX-512 optimizations but they didn’t affect clock speeds. My goal was to see if reducing clock activity would more reliably control temperatures, rather than relying solely on power caps.
Tried a different method to reduce power usage. Instead of adjusting voltage, I manually lowered the power limit and experimented with manual voltage settings. This helped maintain stable performance across various scenarios. On my CPU (10700K), when running heavy loads, the clock would stabilize at around 4.7GHz, but with two threads it fluctuated between 5.1GHz and 4.9GHz before crashing due to low voltage. I found that setting Vcore to 1.200V with LLC on Low kept temperatures under 80°C during full loads and reduced consumption to about 185W while handling the 16-thread P95 small FFT.
