Following reports of damage to AMD Ryzen 7000X3D processors and motherboard sockets, manufacturers such as MSI, Asus, and Gigabyte have released new firmware updates to address potential issues. To prevent further harm to the components, the latest BIOS blocks SoC voltage for these chips to protect the CPU and motherboard.

AMD's subreddit users have been posting rather haunting images lately. One such example is Speedrookie's post, where you can see the scorch marks within the CPU socket and bulging on the CPU contact pads of an AMD Ryzen 7800X3D and Asus ROG Strix X670E-E Gaming motherboard. There are more users reporting similar issues with their recently acquired Ryzen 7000X3D CPUs, most of them on Asus X670E motherboards. However, considering MSI and Gigabyte's response to this problem, it may not be exclusive to Asus motherboards.

Although there is no clear understanding of what has caused the problem, manufacturers are taking steps to address the issue with new firmware. The new BIOS blocks direct voltage adjustment and locks down the voltage controls for X3D chips by removing support for positive offset voltages. As such, with the latest firmware, it's only possible to use negative offset voltages on X3D chips, which will help to ensure that the sensitive V-Cache-equipped X3D chips can't be overvolted and damaged.

Manufacturers have released new BIOSes for most, if not all, of its AM5-based motherboards, including X670E, X670E, B650, and A620 models. Besides the BIOS, MSI also locked overvolting through the MSI Center app on systems running Ryzen 7000X3D processors, preventing users from overvolting within the OS. Still, users can utilize PBO and related settings such as Enhanced Mode Boost (MSI), Performance Bung (Gigabyte), and PBO Enhancement mode (Asus), as they don't require any manual voltage adjustment.

KitGuru says: If you have a Ryzen 7000X3D CPU on an AMD 600-series motherboard, we recommend downloading the latest BIOS for your board to prevent this issue, even if it's currently in beta.

Nvidia Corp.’s latest graphics processing units based on “Maxwell” architecture are rather good overclockers, but only to a certain degree. According to Vince “K|NGP|N” Lucido, a professional overclocker, without extreme methods of cooling (such as use of liquid nitrogen, chiller or other), most “Maxwell” GPUs just do not work at frequencies beyond certain limits even with ultra-high voltages, which is why in many cases it is useless to just amplify GPU voltage supply.

In a bid to overclock a microprocessor or a graphics processing unit, one needs to cool it down properly and increase voltage because operation at higher clock-rates requires additional power. Since higher power consumption means higher heat dissipation, requirements of better cooling increase with every additional 0.1V. Some previous-gen Nvidia GPUs could handle extreme temperatures and therefore could be overclocked to record frequencies even with air or water coolers. However, everything is different with “Maxwell”. The new graphics processing units from Nvidia require both additional voltage and exotic cooling methods to be overclocked to extreme frequencies.

What it means for end-users and makers of graphics adapters with fine coolers is that they will be unable to overclock “Maxwell” GPUs beyond certain points no matter what voltage they apply.

“With GeForce GTX 980 [GM204] and later GPUs, including GeForce GTX Titan X [GM200], the scaling on air/water has all but almost gone,” said Mr. Lucido in a forum post. “I would say about 95 per cent of all [Maxwell-based graphics cards] no matter [from] what [graphics card] brand, do not scale with more voltage than 1.25v-1.275v at temps warmer than 25°C or so. There is no magical BIOS that can effectively remove this.”

It is unknown why “Maxwell” architecture does not scale with extra voltage alone, but it is clear that with stock or hybrid coolers and additional voltage it will be impossible to hit clock-rates of over 1500MHz. If a maker of graphics adapters wants to create an ultimate GeForce GTX 900-series graphics card with extreme frequencies, it will need to bin GPUs that can actually hit such clock-rates without using of liquid nitrogen.

“This is the behavior of most ‘Maxwell’ [GPUs] with voltage/ambient cooling (20°C – 60°C),” said the legendary overclocker. “The GPUs generally don't scale clocks with voltage on air (max ambient [frequency is] 1500MHz – 1600MHz), it won’t matter what GPU you are using or what voltage control you have to use, especially when clocked already over 1400MHz. The overclocking on air is limited to the bin of the GPU and what it does at nearly stock voltage.”

KitGuru Says: Keeping in mind that most enthusiasts do not overclock their hardware to frequencies that are 30 – 40 per cent higher than stock speeds, the vast majority of such people will never notice the limitation. However, if you are using a stock cooler and want to hit extreme clock-rates, do not risk with overvoltaging: it simply does not matter in your case.
