Following reports of chips burning out, Gigabyte says its AMD Socket AM5 SoC voltage levels are safe

In light of reports that excessive SoC voltage has been linked to damage suffered by certain Ryzen 7000-series CPUs, motherboard manufacturers are pushing out BIOS updates and explanations, hoping to contain the fallout. Gigabyte released a statement, saying its motherboards are compliant with AMD's 1.3V recommended limit (at least with the latest beta BIOS updates anyway).

In the statement, Gigabyte says: "Users can use HWiNFO software to accurately monitor the CPU internal SOC Voltage (SVI3 interface), which is indicated as 'CPU VDDCR_SOC Voltage (SVI3 TFN)' in HWiNFO. This value is reported by the internal sensor of the CPU to show the true voltage. Gigabyte uses HWiNFO to monitor the SOC Voltage on AM5 motherboards and it is under 1.3V, which is officially confirmed by AMD."

Gigabyte released a video on YouTube as shown above. It shows the all important HWINFO SVI3 readout is under 1.3V at all times, while readouts with a voltage probe showed spikes of up to 1.35V. That's well over the 1.3V safe limit stated by AMD.

The implication is that the SoC voltage read points on Gigabyte boards are not reading the SoC voltage actually being delivered to the CPU. The statement goes on to say, "PWM Output Voltage will be higher than the CPU internal SOC Voltage (SVI3 interface) due to various physical factors."

That's a surprise, as voltage read points are generally regarded as being more accurate than software readouts. Of course, that's only going to be the case if the SoC read point is reading the right thing. In this case it's obviously not.

Discrepancies in voltage measurements may be the source of some reports (such as this one from Gamers Nexus) claiming certain Asus motherboards were still applying SoC voltages above 1.3V, even after installing updated BIOS with limits in place.

We'll have to wait and see if reports of damaged CPUs will taper off. Not everyone updates their motherboard's BIOS and most won't go anywhere near manual voltage controls.

But this is a special circumstance. If you're reading this and use an AM5 motherboard, please update your BIOS, particularly if you're running a Ryzen 7000-series X3D chip. If you don't update, at least manually set your SoC voltage to a level under 1.3V to play it safe.

Chris' gaming experiences go back to the mid-nineties when he conned his parents into buying an 'educational PC' that was conveniently overpowered to play Doom and Tie Fighter. He developed a love of extreme overclocking that destroyed his savings despite the cheaper hardware on offer via his job at a PC store. To afford more LN2 he began moonlighting as a reviewer for VR-Zone before jumping the fence to work for MSI Australia. Since then, he's gone back to journalism, enthusiastically reviewing the latest and greatest components for PC & Tech Authority, PC Powerplay and currently Australian Personal Computer magazine and PC Gamer.
