ASUS is moving quickly to support AMD’s newest high-end desktop processor, rolling out fresh X870 motherboard BIOS updates built on the latest AGESA ComboAM5 1.3.0.1 firmware. These new beta BIOS releases are tuned specifically for the newly announced Ryzen 9 9950X3D2 Dual Edition, a flagship chip aimed at enthusiasts, creators, and demanding multitaskers.
AMD’s Ryzen 9 9950X3D2 Dual Edition is grabbing attention as the first CPU said to feature dual 3D V-Cache stacks. On paper, it’s a monster: 16 cores, a huge 208 MB cache pool, and a 200W TDP designed to deliver strong performance across heavyweight gaming, production workloads, and mixed-use scenarios. With a launch this significant, motherboard makers are rushing out firmware updates to ensure the best compatibility, stability, and performance.
According to ASUS, its newest beta BIOS builds introduce AGESA ComboAM5 1.3.0.1 and include optimizations targeted at the Ryzen 9 9950X3D2 Dual Edition. ASUS also notes an adjustment involving its Crosshair Tweak feature: when using Mode 2 on Crosshair-series boards, the same memory rules as the test BIOS 99xx are applied. In other words, ASUS is not only preparing for the new CPU, but also refining memory-related behavior to align with its latest testing logic—something that can matter a lot for users pushing DDR5 speeds, tuning timings, or chasing maximum stability.
Here’s the official change list ASUS provided for these beta BIOS updates:
1. Update to AGESA ComboAM5 1.3.0.1 (BETA)
2. Optimized for the 9950X3D2 Dual Edition
3. Add Crosshair Tweak item (When using Mode 2 in the Crosshair series, the same memory rules as the test BIOS 99xx are applied)
ASUS says the new beta BIOS is available across a wide range of X870 and X870E models, including ROG Crosshair, ROG Strix, TUF Gaming, and ProArt boards. The supported models include:
If you’re planning to upgrade to the Ryzen 9 9950X3D2 Dual Edition—or you simply want your ASUS X870/X870E system ready for the newest AGESA improvements—these beta BIOS releases are the first wave of firmware designed with this CPU in mind. As with any beta BIOS, users should expect ongoing refinement, so conservative upgraders may prefer to wait for a final release, while enthusiasts and early adopters will appreciate having day-one tuning and compatibility updates available.
