Project reference finn ram 128gb upgrade

name: Finn RAM upgrade: 128 GB (2×64 GB DDR5 SO-DIMM) description: Justin purchased 128 GB DDR5 SO-DIMMs for Finn (MS-01); works despite Intel's 96 GB spec limit; BIOS flash required before install type: project

Justin purchased 2×64 GB DDR5 SO-DIMM sticks to upgrade Finn (MS-01) from 32 GB to 128 GB. This exceeds Intel's official 96 GB spec for the i9-13900H but is community-confirmed to work on the MS-01.

Key facts: - Current state: 32 GB (2×16 GB), host oversubscribed ~1.46×, 7.3 GB swap in use - Incoming: 128 GB (2×64 GB DDR5 SO-DIMM, 262-pin laptop form factor) - Must flash latest Minisforum BIOS before or immediately after swap or risk no-boot/memory-training hangs - RAM will likely train at lower speed (~3600-4400 MT/s instead of 5200); irrelevant for a virtualization host - After install: bump Console VM from 12 GB to 48-64 GB (qm set 103 -memory 49152 or higher) - Unlocks 5 always-on CreatorTrack dev server previews + parallel agent sessions comfortably

Why: Finn's 32 GB is oversubscribed 1.46× with 11 running guests; Console is hard-pinned at 12 GB with no room to grow; parallel-agent dev workflow needs more headroom.

How to apply: When Finn RAM context comes up, note the upgrade is already purchased (not yet installed as of 2026-06-19). First step post-install is BIOS flash, then qm set 103 -memory 49152.

Auto-memory addendum 2026-06-20T16:01:07.080628¶

Finn's physical RAM was upgraded to 128GB as of 2026-06-20. Confirmed via free -h: 125Gi total (firmware/iGPU reservation accounts for the delta), 27Gi used, 98Gi available, swap 8Gi nearly idle.

Why: Hardware upgrade to expand headroom for LXC container allocation, ARC/cache tuning, and new services including beefier Postgres on forge-data CT 109.

How to apply: When planning LXC RAM budgets, new service deployments, or Postgres tuning on CT 109, base calculations on ~125Gi total / ~98Gi available (as of upgrade date; actual free will drift as services scale). A finn-memory-capacity-plan_Opus48 tmux session was active at upgrade time planning reallocation strategy.
