MSI today announced that its full 300-series motherboard lineup, which includes A320, B350 and X370 chipset-based motherboards, now support AMD's latest Zen 3 CPUs in the Ryzen 5000 series. The full support will be backed into BIOSes developed under the latest AMD AGESA COMBO PI V2 1.2.0.7 BIOS, which MSI expect to rollout for its 300-series motherboards from the middle of May this year.

This announcement from MSI builds upon AMD's own promises of research into adding support for more recent Ryzen architectures towards even the beginning steps in its AM4 ecosystem. In theory, users rocking older motherboards can now take advantage of AMD's latest developments in power, performance, and core density, deeply increasing - and confirming - the value proposition of AMD's AM4 platform. Alongside the announcement, MSI has also pledged to launch a fix for fTPM-based stuttering issues present in 400-series and 500-series AM4 motherboards towards June.

BIOSTAR, a leading brand of motherboards, graphics cards, and storage devices, today announced product support for the latest AMD Ryzen 5000G series Cezanne processors. AMD's next-generation Ryzen 5000G series desktop processors codenamed "Cezanne" are ready to invade the global market. The new 5000G series processors are based on Zen 3 architecture, AMD's Ryzen 5000 series of desktop APUs based on the Zen 3 CPU and Vega GPU microarchitectures succeeding the Ryzen 4000 "Renoir" series.

Extreme performance enabled for personal computing with up to 8 cores fueled by the world's most advanced 7 nm processor core technology, the AMD Ryzen 5000 G-series desktop processors with Radeon graphics deliver ultra-fast responsiveness and multi-threaded performance for any use case.

In a controversial move that baffles our technical understanding of how processor+chipset (platforms) work, Intel has decided to restrict the mid-tier B460 and entry-level H410 desktop motherboard chipsets from supporting 11th Gen Core "Rocket Lake-S" processors. A BIOS Updates Support page for Intel 400-series chipsets on the company website mentions "Motherboards based on Intel B460 or H410 chipsets are not compatible with upcoming 11th Gen Intel Core processors."

The company states that only the top Intel Z490 and next-best H470 chipsets support "Rocket Lake-S" from the 400-series, and such motherboards require a BIOS update from the motherboard manufacturer or pre-built OEM. We're having a hard time figuring out why the B460 or H410 have been excluded. With the H410, an argument can be made on insufficient CPU VRM capabilities of most motherboards; but the same can't be made for the B460, with several motherboard manufacturers having developed premium DIY motherboards with capable VRM solutions (eg: the ROG B460-F Gaming, or B460 AORUS Elite). Those looking to save some dough on mid-tier motherboards to use with "Rocket Lake" should now wait for Intel to launch the B560 chipset.

MSI announced that it is bringing the PCI-SIG resizable base-address register (resizable BAR) support to a variety of older PC platforms, and not just the latest Intel 400-series and AMD 500-series. Among these are Intel 300-series, AMD 400-series, and AMD TRX40. This should come as a boon to those with 8th Gen and 9th Gen Core "Coffeee Lake" processors, such as the i9-9900K and i5-8400. Support is also being added to AMD X470 and AMD B450 chipset motherboards, however, this requires a compatible processor, and the latest beta UEFI firmware that supports them. Lastly, resizable-BAR support is making its way to the AMD TRX40 chipset (Socket sTRX4) Threadripper platform.

Resizable BAR is a feature that allows a processor to see the entire video memory of a discrete GPU as a single addressable block, rather than through 256 MB apertures. This has the potential to tangibly improve performance with certain games. Currently, AMD's Radeon RX 6000 series "Big Navi" GPUs; and NVIDIA's GeForce RTX 30-series "Ampere" GPUs support it. MSI is releasing UEFI firmware updates that add resizable-BAR support. Keep checking the "support" section of your motherboard's product page on the MSI website.

As a world-leading motherboards brand, MSI commits to deliver gamers and creators genuine pleasure, and will keep moving. BIOS update is always an exhilarating news for most users, so MSI keeps announcing relative news for our users. From this week, MSI will release AMD AGESA COMBO PI V2 1.1.0.0 Patch D BIOS for all AMD 400-series motherboards and it is expected to be completely uploaded before the end of 2020.

All AMD 400-Series Motherboards Comprehensively Support Ryzen 5000 CPU with AMD AGESA COMBO PI V2 1.1.0.0 Patch D
The purpose to keep releasing BIOS update is not only for increasing motherboards performance but also for better compatibilities. After AMD launches Ryzen 5000 CPU, most are inquisitive about whether Ryzen 5000 CPU is compatible with AMD previous platforms. MSI realizes that users are eager to enhance their motherboards with the latest CPU; therefore, we are determined to offer AGESA 1.1.0.0 Patch D for all AMD 400-series motherboards. With AGESA 1.1.0.0 Patch D, your 400-series motherboards can support Ryzen 5000 CPU and achieve its true performance. Since there are some technical issues on AGESA 1.1.8.0, it will not be released. Thus, AGESA 1.1.0.0. Patch D is the finest choice to update your motherboards.

As a world-leading motherboard brand, MSI contributes to providing gamers and creators extremely pleasant experience when users choose MSI motherboards. For the sake of fulfillment of goals, MSI keeps updating the latest version BIOS for users to download and to increase performance. At the present, MSI prepares to release BIOS update for all Intel 400-series motherboards, including Z490, B460 and H410 chipsets. According to planning schedule, the first batch is expected to Z490 motherboards. All BIOS update for Z490 will be available by this week. As for B460 and H410 motherboards, the BIOS update will be completely released in the next two weeks. Please follow the product pages for the updated BIOS.Update 10:14 UTC: One of the screenshots provided by MSI in its press release puts out some juicy info about a 11th Gen Core "Rocket Lake" processor ES. Apparently this chip has a multiplier range between 8.0 to 50.0, a nominal clock speed of 3.40 GHz, and 4.30 GHz boost. The CPU-Z screenshot also confirms AVX-512F ISA support. In all likelihood (given that this chip has Rocket Lake's maximum core-count of 8-core/16-thread), this ES could very well be the Core i9-11900.

AMD has announced they will be introducing Adaptive Undervolting tools for their precision Boost Overdrive software, available for the latest Ryzen 5000 series CPUs. This feature will be made available come launch of AGESA 1180 on 400-series and 500-series motherboards (estimated availability in early December), and will require a BIOS update to enable at the software level. According to AMD, this tool will dynamically calculate the precise amount of voltage required for a given task, analyzing internal sensors (such as workload, temperature, socket limits) and adapting voltage values on the fly at up to 1000 times a second.

This approach by AMD will bring a new age for CPU undervolting, which usually only allows for users to undervolt their CPU on the basis of the worst-case scenario: usually, the way undervolters work is by incrementally reducing the CPU's voltage and testing for stability via stress applications, gaming, or other specialized applications. This means that the CPU will have adequate juice so as not to fail in these scenarios - but of course, your CPU isn't always (in fact, it's almost never, depending on your specific use-case) using the full CPU processing power; this means that all other workloads where the CPU isn't under 100% utilization still have room for voltage reductions. With AMD's Adaptive Undervolting, this will now become possible.
