AMD AM5 motherboards have been encountering frequent SoC voltage issues in recent weeks. There were some reports of Ryzen 7000X3D processors burning. AMD and motherboard manufacturers are releasing new updates to fix the problems.
As for Gigabyte motherboards, there were reports that the SoC voltage exceeded the critical point of 1.3 V when EXPO was enabled with the latest beta BIOS update. The hardware manufacturer, on the other hand, made a statement regarding the reactions to the agenda:
“We would particularly like to address recent media reports of SoC voltage exceeding 1.3V on AMD AM5 motherboards when EXPO is enabled in the latest beta BIOS.
Gigabyte respects and appreciates the media’s longstanding support. The actual measurement point and method is critical, as the SoC voltage measurement varies according to the vehicle used and the scenario. CPU internal SoC Voltage (SVI3 interface) is the most important indicator for motherboards, and in general the PWM Output Voltage will be higher than the CPU internal SoC Voltage (SVI3 interface) due to various physical factors.
Users can follow the indicators labeled as “CPU VDDCR_SOC Voltage (SVI3 TFN)” from the HWiNFO software to accurately monitor the CPU internal SoC voltage (SVI3 interface). This value is reported by the CPU’s internal sensor to show the actual voltage. Gigabyte uses HWiNFO to monitor SoC voltage on AM5 motherboards, and we see that it’s below 1.3V officially confirmed by AMD. All Gigabyte AM5 motherboards follow AMD’s latest “SOC Voltage 1.3V Guidelines” when EXPO is enabled. Check out the video below for more details.”
We have seen similar claims on ASUS side. Hardware BustersIn his tests using the Gigabyte AORUS Master X670E motherboard, he noticed that the motherboard went above 1.3V with EXPO enabled.
A voltage value of 1.04V is reported when using the old F7 BIOS without EXPO, but up to 1.416V was seen when running the Prime95 stress test as soon as EXPO was enabled. The new BIOS claims to fix and limit the SoC voltage, but even with the F10D Firmware installed, the voltage can still exceed 1.3V to reach 1.361V.
