AMD’s Ryzen 7000 Desktop CPU Undervolting Might Supply Important Frequency & TDP Headroom Whereas Dropping Down Temps
Within the earlier report, we acknowledged how AMD’s Ryzen 7000 CPUs have been alleged to run actually scorching even at inventory TDP scores. The Ryzen 9 7950X with a PPT of 230W and the Ryzen 5 7600X with a PPT of near 130W are mentioned to hit 90-95C temperatures at inventory configurations which is sort of on the edge of their thermal threshold. After hitting this threshold, the CPU will downclock itself and run at a lot decrease frequencies of 5.0 GHz, a drop of -700 MHz.
If set guide V with identical CLK, can get MUCH affordable end result. And there’s a lot of CLK/temp headroom.
Greater than 3 weeks for launch. Wait and hope to repair this.
Many thanks for tip! ☺️

Now Harukaze5719 has came upon to AIDA64 entries that are allegedly from an AMD Ryzen 5 7600X CPU. The primary end result reveals us the inventory configuration the place the ES chip is seen operating at a frequency of 5.05 GHz. The temperature may be seen sitting at 93.1C at 122W within the AIDA64 FPU stress take a look at. It is a actually excessive temperature however within the second window, we will see a guide Vcore adjustment which drops the temperature considerably all the way down to 56.5C and in addition the wattage to only 68 Watts whereas retaining the 5.05 GHz.
It’s probably that there could possibly be an influence or voltage bug within the AMD Ryzen 7000 ES/QS components which is resulting in such excessive temperatures however undevolting kind of fixes the difficulty. Now it stays to be seen whether or not the manually alter voltage will probably be ok to deal with the 5.5-5.7 GHz clock speeds that the Ryzen 7000 CPUs have to supply. It could possibly be potential that the undervolting is sweet sufficient for a 5 GHz clock pace however extra voltage can be required to hit the upper frequencies.
Contemplating that the Zen 4 chiplets are smaller than their predecessor however a lot denser, they’ll require lots of cooling. It seems like that is likely to be one purpose why the chiplets are additionally gold-plated this time to successfully transfer as a lot warmth away from them and to the IHS. A new screenshot by leaker, Fanatic Citizen, reaffirms his declare although as soon as once more, the result’s primarily based on an ES chip and the issue might have been tweaked within the remaining silicon:
All of which means that customers ought to positively sit up for investing in some actually high-end AIO coolers in the event that they plan on constructing a brand new PC with AMD’s Ryzen 7000 Desktop CPUs. After all, that is only a rumor for now and we’ll watch for remaining exams and opinions to substantiate the validity of this rumor however AMD has put of their greatest efforts to ensure that warmth is dissipated off the CPUs by issuing a gold plating on each the IHS and the Zen 4 CCDs as detailed right here. The AMD Ryzen 7000 CPUs launch alongside the AM5 platform on the twenty seventh of September.
