  • 64 MB BIOS ROM enables future CPU upgrades with better compatibility
  • 18+2+1 DRPS power stages rated at 110 A deliver stable overclocking headroom
  • Frozr cooling design with wavy fins, direct-touch heat pipes and double-sided M.2 shields keeps temperatures low
  • Dual 10G and 5G LAN ports provide high-throughput wired networking for gaming and work

Socket AM5 combo

The bundle pairs the MEG X870E ACE MAX motherboard with an AMD Ryzen 9 9950X3D processor. It targets enthusiasts who want a ready-to-run platform for heavy multitasking and high-frame-rate gaming. The board supports Ryzen 9000, 8000 and 7000 series CPUs out of the box.

DDR5 ceiling and lane budget

Four DDR5 slots accept up to 256 GB in dual-channel mode at speeds beyond 9000 MT/s when overclocked. Two PCIe 5.0 x16 slots and two PCIe 4.0 x16 slots share bandwidth with five M.2 sockets that run at PCIe 5.0 x4 or 4.0 x4. Four SATA 6 Gb/s ports add legacy storage headroom.

VRM thermal stack and I/O spread

An 18+2+1 phase DRPS design rated at 110 A per stage feeds the 170 W Zen 5 chip, cooled by wavy fin heatsinks, a cross heat-pipe and a metal backplate. Dual-sided M.2 shields keep drive temps in check. Networking uses 10 GbE and 5 GbE ports, while audio runs through a Realtek ALC4082 codec.
