Gigabyte has denied reports that the Ryzen 7000X3D chips were not voltage limited to safe levels

Gigabyte has dismissed a number of media and blogger claims that its new BIOS for AMD socket AM5 motherboards does not lower the Ryzen 7000X3D’s SoC voltage to a safe 1.3V, particularly when AMD EXPO RAM overclocking profiles are enabled.

The manufacturer issued a statement and also posted a video on its YouTube channel, refuting the findings of a number of publications and video bloggers who claimed that while the new BIOS limited the Ryzen 7000X3D’s voltage to protect against burnout, it did however, is not the case in the manner recommended by AMD. In particular, a note from Igor’s Lab states that the new BIOS limits the voltage of SoC processors from 1.42V to 1.36V. However, AMD recommended limiting this value to 1.3V.

Gigabyte emphasizes that when measuring the voltage of the SoC processor, the measurement method and the source from which the measurement is taken are important. In the same issue of Igor’s Lab, voltage tests were performed with a multimeter using SoC voltage measurement points directly on the Gigabyte motherboard. The company points out that the most accurate SoC voltage reading comes from the CPU’s internal SVI3 interface itself.

When measuring the PWM output voltage on the motherboard, the value will always be higher than the internal SoC voltage value via the SVI3 interface, the company explains. The farther the SoC voltage measurement point is from the processor, the higher the value of this indicator, which is explained by the physical characteristics when transmitting signals from the chip to the multimeter connection point. Therefore, the meter data showed an “overestimated” voltage value, which can also be seen in the video published by the company.

According to Gigabyte, users can use the HWiNFO utility, which monitors the CPU SoC voltage parameter directly through the SVI3 interface. In the HWiNFO program itself, this indicator is displayed as CPU VDDCR_SOC voltage parameter (SVI3 TFN). The value of this indicator is transmitted directly through the CPU’s internal sensor and shows the actual voltage of the SoC processor.

In its video, the company demonstrated the process of measuring the voltage of the SoC processor. The HWiNFO program has shown that the new BIOS allows the processor to operate at voltages below 1.3 V, which has also been officially confirmed by AMD, Gigabyte adds. It should also be noted that the test was performed with memory modules that support the AMD EXPO DDR5-6400 overclocking profile.
