Meanwhile, some (few) users reported serious problems with the new AMD Ryzen 7000 processors, which had led to destroyed CPUs and motherboards. My friend Aris discovered, actually rather by accident, an interesting thing, which he had measured with his Powenetics v2, a shunt-based measurement setup and also logged. I don’t want to withhold this from you, because I already made high-resolution measurements with my oscillographs at the time of the Intel Core i9-12900K, where so-called transients occurred that looked similar. However, not to this extreme as now with the new Ryzen CPUs.
Aris has already reviewed several CPUs like the AMD Ryzen 7 7800X3D, AMD Ryzen 9 7950X3D, AMD Ryzen 9 7900X, AMD Ryzen 9 7900 and the AMD Ryzen 5 7600X. Therefore I recommend you to read the Original article on his hwbusters.com homepage with all tested CPUs because I only picked the Ryzen 9 7950X as an example for this news, for which I also have measured values from my own practice. And yes, you can only be amazed. Apart from that: Aris’ homepage is a treasure trove for technical details, especially the power supply tests. You should definitely bookmark it, even if articles by him appear or are mentioned here from time to time.
As it seems, we were both lucky that we didn’t have any problems with burned processors and/or motherboards due to excessive power consumption during our intensive measurements and tests. This was not the case with some users on Reddit, notably Speedrookie, who destroyed his motherboard and CPU. This user also stated at the time that he did not overclock his 7800X3D CPU, but only used the EXPO 1 profile for the RAM. He also hadn’t noticed any temperature or performance issues and his system was running 24/7 (i.e. all the time).
He left the system idle and when he went to use it again, he noticed that the system could no longer post and had a QCode of 00. The AIO cooling he was using was hot, too hot as he described, showing that it was getting tremendous load from the CPU, which is odd considering the system was idle. His mention of leaving the system idle for a while and then finding that his processor was burned up then led Aris to look more closely at the idle log data he got from his Powenetics v2 and subsequently test some more load scenarios and other processors.
Ryzen 9 7950X3D
| State | Power Consumption |
| Idle Peak (PBO/CO-15) | 130.04 W (124.73 W) |
| Idle AVG (PBO/CO-15) | 50.531 W (45.952 W) |
| Blender Peak | 189.586 W |
| Prime95 (small FFTs) Peak | 170.352 W |
There is a high peak of up to 130W during idle with the Ryzen 9 7950X3D, which is actually unjustified since the highest CPU load is only 3.53%. Even with curve optimization enabled and a setting of -15, the idle peak remains at 125W, so something is happening here that shouldn’t be happening like this. Aris tested all the CPUs on three motherboards from Asus, MSI and Gigabyte. More details about the test systems can be found in the corresponding tests from Aris on their homepage, which I can only recommend.
Aris and I are of the opinion that these load peaks (which I could reproduce 1:1 in the meantime, by the way), primarily have nothing to do with the described CPU dying – we put a lot of emphasis on that to avoid a false panic. But on the other hand, such transients are nothing you need for a really stable system. Aris has also already spoken to some of his industry contacts, who have told him that the overall RMA rates of the 7000 series are actually lower than those of the 5000 series. This should avoid panic and also not discourage anyone from buying a new AMD CPU.
