The Ryzen 9 7950X3D processors presented at the end of February, described by AMD as the fastest gaming processors in the world, proved to be extremely unreliable. Users complain about processor failures in the first days or weeks of use. Our own laboratory has a similar experience.
The life path of problematic Ryzen 9 7950X3D instances looks roughly the same: the processor works for several days, then the system spontaneously turns off and never turns on again. Most surprisingly, this happens in standard mode with no overclocking.
At Reddit a whole thread is already dedicated to the bad experiences with defective Ryzen 9 7950X3D. In particular, statistics show that it can take as little as 12 hours to a whole month for the chip to fail. The symptoms are the same for everyone as described in the paragraph above. Replacing the motherboard and other PC components doesn’t help in any way – the processors turn out to be completely dead. We also note that the processors have died on both motherboards with the AMD X670E chipset and the more recent B650.
The Ryzen 9 7950X3D that arrived at our lab also broke down. Three days passed before its failure, and all this time the processor worked in nominal mode without overclocking. The test copy of the Ryzen 9 7950X3D almost immediately failed the channel’s authors Pro Hi Tech (You will talk about this in detail in one of the following videos). And popular blogger Linus Sebastian even made a video about how he couldn’t test AMD’s flagship processor because the company sent him two defective CPUs in a row.
Before that, complaints about Ryzen 9 7950X3D glitches came from overclockers – in March we wrote that the notorious Roman “der8auer” Hartung (Roman Hartung) accidentally burned the AMD flagship by raising the voltage too high. However, as practice shows, even operation without overclocking does not guarantee reliable operation.
Remember that the Ryzen 9 7950X3D processor differs from the regular Ryzen 9 7950X in the presence of a 3D cache – an additional SRAM chip located on one of the processor’s CCDs. Perhaps this is the reason for the higher sensitivity of the processor – the memory chip makes it difficult to remove heat from the processor cores. However, this is only a guess – no official comments have yet been received from AMD on this topic, although problems have been observed for a month since the start of sales.
A high level of marriage was also noted on the regular Ryzen 9 7950X. For example, one of the two processors purchased by the 3DNews lab had a faulty memory controller. And on Amazon, about 5% of buyers complain about the inoperability or instability of the new Ryzen 9 7950X.
