Best RAM for ASUS ROG Ally X & Performance Optimization Matrix
The ASUS ROG Ally X is the enthusiast upgrade to the original Ally, solving the unified memory crunch by shipping with 24GB of high-speed LPDDR5X memory running at 7500 MT/s. This allows the APU to reserve 8GB for VRAM while maintaining a full 16GB dual-channel desktop equivalent configuration for the OS.

UMA Frame Buffer Advice
The ROG Ally X solves the 16GB memory bottleneck by including 24GB of ultra-fast LPDDR5X-7500. By default, it allocates 8GB to VRAM, leaving a massive 16GB entirely for system threads. This eliminates texture paging stutters completely. You do not need to tweak UMA allocation unless a specific game requires a 16GB VRAM footprint.
Frequently Asked Questions (FAQ)
Why does the ROG Ally X have 24GB of RAM instead of 16GB?▼
The extra 8GB of RAM resolves the unified memory bottleneck. It allows you to assign 8GB to graphics (VRAM) for high-resolution textures, while still maintaining 16GB for Windows and game code, preventing memory bottlenecks.
Is the LPDDR5X RAM on the Ally X upgradeable?▼
No. The LPDDR5X memory is permanently soldered to achieve the high 7500 MT/s speeds and maintain thermal efficiency.
