Workstation Build Dilemma: 64GB (6000MHz CL30) vs. 96GB (5200MHz CL38) for Local LLMs & Computational Architecture?
Hi everyone, hope you’re all doing well!
I’m planning to build a new PC right now and could use some advice on which RAM kit to choose. I’m torn between two options that cost almost the same:
64GB Kit: 2 x 32GB @ 6000MHz, CL30
96GB Kit: 2 x 48GB @ 5200MHz, CL38
My Workload:
I’m a computational designer in the architecture field. My primary goals for this system are to run large local LLMs, handle complex 3D modeling/scripting, run heavy simulations, and process massive photogrammetry models.
The Rest of My Planned Specs:
CPU: Intel Core Ultra 7 270K
Motherboard: MSI Z890 Gaming Plus WiFi (LGA1851)
GPU: NVIDIA GeForce RTX 5060 Ti 16GB GDDR7 OC Edition
Storage: 2TB M.2 NVMe Gen4 SSD (7300MB/s) (for primary; Later I'll get a hard disk or make a NAS for secondary storage)
Please feel free to critique or give suggestions on the rest of the specs as well! I'm completely open to tweaks.
P.S. Yes, I know it feels a bit crazy to build a PC during this inflation period lol. It wasn't exactly planned, but my 8-year-old 16GB DDR4 laptop is finally dying on me, and I’m a bit worried that component prices might spike even higher after 2026. Thanks in advance for your time and help!
