MSI MEG X570S ACE MAX AMD motherboard

SKU CH-3RGJ-EB35V

ATX board for AM4 Ryzen CPUs with 16+2+1 phase 90A power, four M.2 slots, eight SATA ports and 128 GB DDR4 5300 OC support

  • ProcessorSupports AMD Ryzen 5000 Series / 5000 G-Series / 4000 G-Seri
  • ChipsetAMD X570
  • Form factorATX
  • CPU socketAM4
  • Memory slot count4 × 288pin (DDR4)
  • Supported memoryDDR4 3200 / 3066 / 3000 / 2933 / 2800 / 2667 / 2400 / 2133 /
  • Supports Ryzen 5000 to 2000 Series processors for broad CPU compatibility
  • DDR4 memory overclocks to 5300 MHz for high-speed performance
  • 16+2+1 phase 90A power design delivers stable current to the CPU

  • Aluminium cover, heat-pipe and 7W/mK pads keep VRM and M.2 drives cool

AM4 Platform Coverage

This motherboard fits the AM4 socket and accepts AMD Ryzen 5000 Series, 5000 G-Series, 4000 G-Series, 3000 Series, 3000 G-Series, 2000 Series and 2000 G-Series desktop processors. It targets enthusiasts who want a single board that spans multiple CPU generations without changing platform. The X570 chipset unlocks full PCIe 4.0 support from compatible Ryzen CPUs.

Memory Capacity And Speed Limits

Four DDR4 slots support up to 128 GB in dual-channel mode with JEDEC speeds from 1866 to 3200 MT/s. A-XMP overclocking can push 1 DPC 1R modules to 5300 MT/s on Ryzen 5000 G-Series and 4000 G-Series processors. Beyond that frequency headroom the memory controller becomes the limiting factor.

Power Phase Upgrade And M.2 Expansion

The 16+2+1 phase VRM uses 90 A smart power stages and dual CPU power connectors, a clear step up from mainstream 10 to 12 phase designs on earlier X570 boards. Four M.2 slots with PCIe 4.0 on Ryzen 5000 and 3000 Series CPUs replace the two or three slots typical of mid-range models. The jump is worth it when you need both sustained high current delivery and maximum Gen 4 storage density.

Questions about this item

Will my existing DDR4-3200 memory work with the four 288-pin slots on this board?

Yes — the board runs DDR4 at JEDEC speeds from 1866 up to 3200 MHz across all four slots, and supports up to 128 GB in dual-channel mode.

How can I verify the Realtek ALC4082 and ESS SABRE9018Q2C audio combo is active after first boot?

Open Windows Device Manager or your OS sound control panel; both codecs should appear as separate audio devices with driver versions listed.

Which cables and brackets ship with the MEG X570S ACE MAX, and what must I source myself?

The box includes SATA cables, M.2 mounting screws, I/O shield and documentation; you supply the CPU, DDR4 modules, storage drives, graphics card and ATX power supply.
