What's arriving: Crucial 64GB DDR5-4800 SODIMM kit (2× 32GB) + WD_BLACK SN850X 2TB NVMe PCIe 4.0 SSD. Total $948.99 + tax.
What you currently have: Apex is a Minisforum HPBSD (EliteMini Series) with 16GB DDR5-5600 in DIMM 0 (DIMM 1 empty), a 512GB Kingston NVMe as the boot drive (59GB free, getting tight), and a second M.2 slot empty. BIOS is version 1.02 dated 3/27/2024 — old enough that we want to update before the install.
Follow these steps in order. Skip none. Each step has a green check when done.
| Component | Current | After |
|---|---|---|
| Motherboard / BIOS | HPBSD, BIOS 1.02 (3/27/2024) | HPBSD, latest BIOS |
| RAM | 1 stick: 16GB A-DATA DDR5-5600 | 2 sticks: 64GB Crucial DDR5-4800 |
| Boot NVMe (Slot 1) | 512GB Kingston (C: + G:, 59GB free) | Same — untouched |
| Second NVMe (Slot 2) | Empty | NEW 2TB WD_BLACK SN850X |

Notes on Minisforum BIOS updates (general pattern from MS-A2/MS-01 docs):
If Minisforum's site doesn't have an HPBSD-specific BIOS update, the current 1.02 may already be the latest. Check with bbs.minisforum.com forum for confirmation.
We are NOT touching the boot drive. But hardware swaps sometimes go sideways. Safer to be conservative:
docker exec tp3_neural_stack_brain_db pg_dumpall -U postgres > backup_2026-05-22.sql/var/lib/docker/volumes/tp3_bidet_dumps/_data to G16 if you want a snapshot of raw transcripts.Per Minisforum's standard pattern (varies slightly by model — trust the BIOS ZIP's README over this):
If you cannot find an HPBSD-specific BIOS update on Minisforum's site: 1.02 may be the only one. Stop here, proceed to physical install. The 1.02 is from March 2024 which is recent enough for DDR5 support.
Static discharge can kill DIMMs and NVMes. Touch the metal case of Apex or an unpainted radiator/sink for 10 seconds before handling components. If you have an ESD wristband, use it. Don't work on carpet.
Minisforum HPBSD (EliteMini): the bottom panel comes off. Look for 4 rubber feet on the bottom — pop them off (they're stickers covering screws), then remove the 4 Phillips screws underneath. The bottom panel lifts off.
You'll see the motherboard with:
The current stick is in DIMM 0. To remove:
The Crucial kit comes as two identical 32GB sticks. Install one in each slot:
This goes in the empty M.2 slot (don't touch the existing Kingston boot drive in the other slot).
Mash Del during boot to enter BIOS. Confirm:
If RAM shows less than 64GB: one of the sticks isn't seated correctly. Power down, re-seat, re-test.
If only one drive shows: the new NVMe isn't seated correctly OR the BIOS needs to re-detect. Power down, re-seat, re-test.
Boot into Windows. Open Task Manager → Performance tab → Memory. Confirm 64.0 GB visible. Speed should read 4800 MHz (or close to it).
C: is at 59GB free of 475GB total. Things that have grown big and don't need to be on the boot drive:
honest-answers/dumps/ directory if you want it off C:.I'll write the migration runbook in a separate step once D: is up — don't rush this. C: only needs to NOT be at 0 free, which after install we'll still have 59 GB. We have time.
Worst-case fallback: re-install the original 16GB A-DATA stick. Apex boots back to known-good config. Diagnose from there.
