AMD has released a second statement on the issues surrounding its Ryzen 7000 processors. The company says it plans to limit the SoC voltage to fix an issue where excessive voltage causes Ryzen chips to partially melt. The damaged chip swelled and overheated, not only removing the solder, but also severely damaging the motherboard it was attached to. Here is the full text:
“We have identified the cause of the issue and have already implemented a new AGESA that prevents the CPU from operating beyond its specification limits, including taking measures on certain power rails on AM5 motherboards to limit the SOC voltage to 1.3V. None of these, this change affects the ability of Ryzen 7000 series processors to overclock memory using EXPO or XMP kits, or use PBO technology to boost performance. increase.
All ODM partners are expected to release new BIOS for their AM5 boards in the next few days. All users are advised to check their motherboard manufacturer’s website and update their BIOS to ensure their system has the latest software for their processor.
If your CPU may have been affected by this issue, please contact us AMD Customer SupportOur customer service team is aware of the situation and is prioritizing these cases. — His AMD representative at Tom’s Hardware.
AMD’s new statement, based on information it provided when it first acknowledged the problem, says it will ensure its ODM partners (motherboard makers) supply the correct voltages for their Ryzen processors.
As pointed out in the first post, failures have been reported on both specialized Ryzen 7000X3D models and standard Ryzen 7000 models. However, AMD’s initial statement only mentioned the 7000X3D variant. This statement does not specify which CPUs are affected, so it should be considered a blanket statement for all Ryzen 7000 and 7000X3D series processors at this time.
AMD now provides AGESA updates to their ODMs, which are the building blocks of the motherboard BIOS firmware distributed by motherboard vendors. AMD says users should check for firmware updates on their motherboards in the next few days. AMD’s statement mirrors a press release stating that all motherboard manufacturers will issue new firmware to fix the issue.
This issue occurs when the user manually adjusts the SoC voltage above 1.3V, or the motherboard firmware automatically raises the SoC voltage above 1.3V when the EXPO memory overclocking profile is enabled. (the EXPO profile itself does not increase). SoC voltage, board vendors assign their own pre-defined values to support EXPO profile acceleration).
According to our own sources, this high SoC voltage can destroy the chip’s thermal monitoring and protection mechanisms, causing cascading failures where the chip demands excessive voltage from the motherboard. Learn more about. In particular, AMD’s statement mentions that the SoC voltage is the root cause, but doesn’t say if it affects thermal monitoring/protection mechanisms.
These higher SoC voltages are needed to support higher memory overclocks, but AMD has shown that the 1.3V limit has no real impact on overclocking headroom. This is an important distinction.
AMD’s warranty does not cover any form of overclocking, including using the EXPO memory overclocking profile. However, the company has said it is prioritizing servicing customers affected by this issue, and it is doubtful that it will honor his RMA for the affected processors.
