AMD appears to be evolving its AM5 desktop roadmap while refining GPU software. Leaks suggest the next-generation Zen 6 MSDT platform (Olympic/Medusa Ridge) may reuse the PROM21 chipset found on current 600/800-series AM5 motherboards, keeping PCIe expansion and dual-chipset needs largely unchanged while adding CPU and new memory form-factor support (CUDIMM/CAMM). Separately, AMD pushed Adrenalin 26.5.1 drivers to improve game compatibility and fix Radeon RX 9000 visual issues, addressing several title-specific bugs though some known issues—especially with Battlefield 6 and Ryzen AI 9 HX 370 systems—persist. Together these stories highlight incremental hardware continuity paired with ongoing software stability work.
AM5 continuity affects platform design decisions for motherboard vendors and system integrators while driver stability impacts gamers and professionals relying on Radeon GPUs. Tech teams must plan hardware refreshes and driver rollout strategies around these incremental changes.

AMD users reported that installing Adrenalin driver 26.5.1 can break the Zero RPM feature on some Radeon GPUs, leaving fans off after system wake and preventing automatic spin-up under thermal load. Tom's Hardware and multiple Reddit posts (first from user Evelyne-Tourneciel) describe persistent fan inactivity after wake, causing throttling, performance drops, and potential hardware risk. A full driver clean with Display Driver Uninstaller and an offline reinstall of 26.5.1 reportedly resolved the issue for at least one user. AMD's follow-up 26.5.2 driver released today does not mention a Zero RPM fix, and the affected card models and scope remain unclear.
AMD released its AMD Software: Adrenalin Edition 26.5.2 GPU driver, adding official support for two new games: Forza Horizon 6 and 007: Origin. The update also fixes two Radeon RX 9000–series issues that could cause intermittent application crashes or driver timeouts in RoadCraft and visual corruption in Satisfactory. AMD flagged an intermittent crash/timeout on Ryzen AI 9 HX 370 platforms running Battlefield 6 and said it is working with developers on a fix and will issue a patch soon. The release continues AMD’s ongoing driver maintenance and game-compatibility updates, important for gamers and developers relying on stability and optimized support for new titles.
Leaked reporting says AMD’s next-generation Zen 6 MSDT (codenamed Olympic Ridge/Medusa Ridge) desktop platform may reuse the PROM21 chipset used across the 600/800-series AM5 motherboards. If true, PCIe expansion on upcoming AM5 boards would remain largely unchanged, and high-end systems would still need dual-chipset configurations to deliver extra lanes. The leak also notes the platform’s key improvements will be CPU and memory support, with full compatibility for newer CUDIMM/CAMM memory module form factors. The detail matters for motherboard makers, DIY builders and OEMs assessing upgrade value and I/O scalability ahead of AMD’s CPU launch. No official confirmation from AMD was cited.
AMD released the Adrenalin Edition 26.5.1 GPU driver on May 7, adding official driver-level support for five games—Pragmata, Honor of Kings: World, INDUSTRIA 2, MONGIL: STAR DIVE, and Tides of Tomorrow—and fixing graphic issues on Radeon RX 9000 series cards. Notable bug fixes include intermittent stuttering in Resident Evil: Requiem’s Raccoon City map and visual corruption in God of War. Known issues remain: Battlefield 6 may crash or trigger driver timeouts on systems with Ryzen AI 9 HX 370 CPUs; enabling AMD Record and Stream can cause texture flicker in Battlefield 6; and FSR/upscaling or frame generation may appear inactive on certain GPUs. The update focuses on compatibility and stability rather than major feature changes.
