can you change tdp on intel 10th gen locked cpu with z490 motherboards?

 

as in unlocking 10400/10700/10900 65watt to sustain all core turbo clocks indefinably ?

also can i undervolte the cpu from bios to reduce heat (if needed since i will be running it in sff case)

if yes does it apply to all motherboards brand or only some of them ?  

 

just want to be sure before buying as i didn't find clear answer online

Well the tdp doens't affect anything, you want to change the turbo limits. A lot of boards let you do that. But it normally doen't make a big differnce as there not limited by the turbo limits much anyways. GN did a video on this, and found that there was basically no noticeable difference in performance.

 

You can normallyundervolt, but that doesn't make a big difference normally either.

I think you can, but the key here is to check the all core turbo limits. I dont think they reduced that too much over the unlocked ones but better check.

The turbo power limits might be locked on a Dell, HP or other OEM board but are generally left unlocked on any decent board from Asus, Gigabyte, MSI, etc.

 

The non-K locked CPUs do not support all core turbo.

 

The 10 core 10900 is a power hungry chip. Being able to increase the turbo power limits beyond 65W can make a significant performance difference when fully loaded.
