MSI hits two birds with one stone with its latest BIOS update for their AMD AM5 motherboards - adding support for 24GB- and 48GB-based DDR5 memory kits and a fix on the currently trending AMD Ryzen 7000X3D and AMD EXPO-related concerns. Read our primer about the AMD Ryzen 7000X3D and AMD EXPO issues here. As of this writing, AMD is yet to release an official statement to the public but AMD has been giving replies to inquiries coming from other tech sites and YouTubers regarding the matter.

Press Release
MSI has been in close contact with the AMD and has referred to their official technical guidance to provide users with a safer and more optimized hardware environment. To achieve this goal, MSI will release a new list of BIOS updates specifically for the AMD Ryzen™ 7000 series CPU.

According to AMD's design specifications, the Ryzen™ 7000X3D series CPU does not fully support overclocking or overvoltage adjustments, including CPU ratio and CPU Vcore voltage. However, AMD EXPO technology can be used to optimize memory performance by appropriately increasing the CPU SoC voltage to ensure system stability when operating at higher memory frequencies.

In the confirmation report from AMD team, it is recommended that the maximum limit of the CPU SoC voltage should be set at a safe range for Ryzen™ 7000X3D series CPU to mitigate potential CPU damage caused by inappropriate overclocking or overvoltage. With the same safety concern, we’ll also adjust the CPU SoC voltage for the regular Ryzen™ 7000 series CPU.

For the new BIOS release, MSI will prioritize this limitation on the CPU SoC voltage. We strongly recommend that users using Ryzen™ 7000 series CPU update their BIOS and use sufficient CPU cooling, such as 280mm or higher AIO cooling, to achieve optimal performance.

At the same time with this update, MSI is also announcing the support of up to 192GB DDR5 memory capacity across all AMD’s AM5 Series motherboards. The update is to ensure that the all-new 24GB and 48GB-based DDR5 memory module kits can fit a maximum of 192GB on all 4 DIMMs or 96GB on 2 DIMMs slots flawlessly across AM5 Series motherboards. The new DDR5 memory modules offer a combination of raw speed and maximum capacity for professionals, creators, and others who rely heavily on multitasking daily and could benefit significantly from better efficiency improvements without affecting overall system latency. MSI has committed to providing the best performance and compatibility to all DIY enthusiasts.
