Reduce TDP Ryzen : compatibility ?

Hi,

I would like to buy a Ryzen (3, 5 or 7) but I would like to reduce the TDP to 35W (because I can't find Ryzen 4000 GE).

I would like to know if all Ryzen (2000, 3000, 4000) can be lowered at 35W ? With any motherboard ?

Is there a list of compatible processors with lower TDP ?

Thank you !

Re: Reduce TDP Ryzen : compatibility ?

You can manually underclock it, cap the multiplier and voltage to very low levels, using Ryzen Master to show the power consumption. Most B and all X series motherboards will be able to accomplish this, though it will take some trial and error to obtain the optimal speed and voltage settings for 35w.

Thank you ! I'm using Linux, is there an alternative for Linux ? This is why I would like to configure it from BIOS, simply by changing the TDP value.

Re: Reduce TDP Ryzen : compatibility ?

As soon as you manually under clock it, it is still going to be an all core clock and thus likely raise the voltage higher if left on auto than if you just left the processor at defaults. 

I know of no way to manage this from within Linux.

I don't know about Linux either, but I would suggest asking in a Linux oriented forums, such as the Phoronix forums.

Thank you, I'll look at this. And what about Ryzen 4000GE ? I can't find it, not released yet ? It could be a good alternative.

As the Ryzen 5000 series launch is imminent, it's likely been discontinued and will likely not be able to buy one at retail.

The new generation BIOSs have TDP limit support. You can give a limit you want to the system with the BIOS. By following this method, you will not lose single core performance.

Thank you, I will wait for Ryzen 5000 instead of 4000.
