In the related news we published on Monday, we conveyed to you that in some systems with Ryzen 7000X3D series processors, a small number of users had a “burn-in” problem and that both the motherboard and the processor became unusable. According to information from different companies and sources, there is a risk of burning not only in Ryzen 7000X3D processors, but also in Ryzen 7000 processors that are not currently X3D.What is the problem and why are AMD processors burning?
Ryzen 7000X3D processors are present in all of the events reported by end users for now. While most of these cases use Asus motherboards, there are cases where other manufacturers such as MSI, Gigabyte and Asrock are also involved. The problem was discovered to be related to the motherboard, and more specifically to BIOSes that do not have the necessary voltage restrictions to stop the CPU from drawing excessive voltage.
As is known, Ryzen 7000X3D processors have AMD’s 3D V-Cache chips. In this generation, AMD also brought users full voltage control for processors. However, 3D V-Cache is extremely sensitive and fragile by nature. For this reason, we can say that these chips are susceptible to overheating and permanent damage to the caches under voltage. Examining a damaged processor closely, Igor’s Lab discovered that the area affected by the burn was the CPU Core Power Supply, or VDDCR. It seems that the specific parameters for the AMD Ryzen 7000X3D CPUs have not been set and the same voltages used for the “X” chips are used for the 3D V-Cache parts, causing higher voltages and several chips to die. In addition, all known events had one thing in common, and that was the use of EXPO.The problem may not be only on X3D processors.

So this may be an indication that the problem can occur not only on X3D processors but also on Other Ryzen 7000 series processors.
Do not overclock the CPU and memory
Asus has already announced that it is working with AMD on new rules for EXPO memory and SoC voltage. Asus states that all problematic old BIOS versions have been retired and new BIOSes have been released. Similarly, MSI and other manufacturers quickly released updated BIOS versions. If you are using new generation Ryzen processors, we recommend updating your BIOS. We recommend that you undo the overclocking and voltage settings, if you have done so, and not use EXPO until the current problems are reported to be resolved. Although EXPO is seen as a feature, the problem may not be covered by the warranty because it is considered overclocking.
