-100G stress test with 0 errors**; highest sampled memory temperature: **56.8°C**. Keep these
-settings rather than increasing voltage further.
+This is the settled configuration for normal use. It passed a **6-hour 100G stress test with 0
+errors** (highest sampled memory temperature: **56.8°C**) and then **29.6 hours of daily use over
+two nights and one workday**, displays on and off, LLM serving throughout. Keep these settings
+rather than increasing voltage further.

+One unbroken boot, 2026-10-09 01:24 to 2026-10-10 07:02: the 6-hour test and a workday with the
+displays on, then a night with them off. Load stayed high — 100G stress test, then continuous LLM
+serving with the KV cache streaming from RAM — and occupancy stayed around 70% or more.
+
+No machine check, hardware error, BUG, Oops, or GPU fall-off; no OOM or hung task; no log gap over
+60 seconds. Sleep/wake is untested — displays off only blanks them. Occupancy and temperature were
+not logged and the board has no EDAC counters, so an error would show up as a freeze or corruption,
+not a count.
