Compatibility Check: PC5-38400 8GB-DDR5-4800MHz for AR Workloads

Hello ScopeAR Community,

I am configuring a new workstation to run ScopeAR's software for developing and viewing AR instructions and remote assist sessions. My goal is to ensure a smooth experience when working with complex 3D models and live video passthrough.

I have the opportunity to use a PC5-38400 8GB-DDR5-4800MHz memory module. I understand this is a server-grade DDR5 module with a high bandwidth of 38.4 GB/s.

Before I proceed, I have a few questions for the experts and developers here:

1. Software Optimization: Is the ScopeAR software stack (e.g., WorkLink, Remote Assist) optimized to leverage the high bandwidth of DDR5 memory, particularly for tasks like real-time 3D rendering and video encoding/decoding?

2. Capacity vs. Bandwidth: For AR development and deployment, is an 8GB module's high bandwidth more beneficial for performance, or would a higher-capacity module (e.g., 16GB or 32GB) be a more critical factor for handling large project files?

3. Platform Compatibility: Are there any known compatibility issues with server-grade or ECC memory on platforms commonly used for AR development, or is standard non-ECC UDIMM memory generally recommended for stability?

Thank you for your insights. I want to ensure my hardware configuration is optimal for a professional AR workflow.

  Thank you for your detailed questions, great to see you planning carefully for your AR workstation setup. Let me address each point:

  1. Software optimization: WorkLink does not require server-grade DDR5 memory. Performance depends more on a capable GPU and modern CPU. Faster memory helps overall responsiveness but is not a key factor.

  2. Capacity vs. bandwidth: For AR development, memory size matters more than bandwidth. We recommend 32GB or more to handle large models and projects smoothly. Using a single 8GB module will be limiting. Aside from that, a strong GPU will have the most impact on frame rate and real-time performance. How much GPU power you need also depends on the complexity of your 3D models (object and triangle count).

  3. Compatibility: Standard non-ECC desktop memory is generally recommended. ECC or server-grade modules can work but they are not required for stability or performance.

  In short, prioritize higher capacity RAM, a strong GPU with 8GB+ VRAM, and a modern multi-core CPU for the best AR experience with WorkLink.
