## 6b. Ember 2: the clocks, the hill-climb, the goal (6 October 2026)
Why: run 5 measured the 5090's power ladder flat (310 to 314 W under every cap from 575 to 400 W, 0.41 MH/W), so
on this memory-latency-bound hash the power cap is a safety, not a lever; the pair that matters is the memory
clock UP and the core clock DOWN. Ember 2 adds both and replaces the fixed ladder with a hill-climb.
| Piece | What | Where |
|---|---|---|
| The memory knob | NVIDIA: `nvidia-smi -lmc <m>,<m>` locks the memory clock to one value, `-rmc` resets; the range is the driver's own (`clocks.mem` under load = the floor, `clocks.max.mem` = the ceiling; PC 1's 5090: 13,801 to 14,001 MHz); directly from an elevated engine or through the Power Helper's `lmc`/`rmc` verbs. AMD: ADLX on RDNA 4 exposes no memory setter through the helper's path, so an AMD card climbs on core and power only (the row says so). Linux NVIDIA: `-lmc` through pkexec as the cap is | `Point.mem_mhz`, `Limits.mem_default_mhz`, `Limits.mem_max_mhz`, `tune_apply`, `powertask::HelperCmd::MemClock`, `sweep::helper_script_*` |
| The hill-climb | from the start point (the fleet prior for the model, else the card's point): each probe moves memory up by 5% of the range above the default (at least 25 MHz) or core down by 5% of the maximum (at least 25 MHz); a probe that improves the goal's score keeps that direction, else the climb turns to the other knob, then to both; 5 probes of 60 s (10 s settle) converge in under 10 minutes | `Plan::climb`, `Climb`, `Plan::climb_next` |
| The stability guard | a rejected or mismatched hash during a probe marks it `faulted`; a faulted probe backs that knob off for good in this climb (memory never goes above, core never below, the last good point); the hash fingerprint is the worker's own self-test at every pack (a variant that is not bit-exact never serves), so a step that keeps mining with 0 mismatches is stable by the only test that matters | `Row::from_samples`, `climb_next`'s `refused_mem` / `refused_core`, docs/design/miner-tuning.md |
| The goal | Settings > goal: `efficiency` (the most MH/W within 10% of the top rate), `balanced` (within 1%, lever 3's rule), `rate` (the fastest point; MH/W breaks ties); one goal for every card | `Goal`, `Settings.tune_goal`, `POST /api/tune/goal {goal, price_pence, climb}` |
| The price | Settings > electricity, pence per kWh: the card's row reads the chosen point as £ a day (`watts × 24 / 1000 × price / 100`: 310 W at 28.5 p = £2.12) | `pounds_per_day`, `Settings.power_price_pence`, the UI |
| The curve | every row of the last plan on the card (`tune_curve`: point, MH/s, W, MH/W, clocks, hottest reading, mark) so a manual tuner sees the points the climb measured | `CardState.tune_curve`, the card detail |
| The fleet | the record's `steps` already carry the curve; the prior gains `mem_mhz` (the median memory clock, 10 MHz steps); a stranger's card of a known model starts its climb at the prior's point | `relay/lib/ember.mjs`, `ember::prior_of` |
| Re-check | weekly (the manifest's period), after a driver major or program-class change, and when the card's temperature band changes (owed: the band trigger) | `tick_sweep` |
Tests: `ember::tests::the_climb_walks_memory_up_and_core_down_and_converges_in_five_probes` (a synthetic
memory-bound card: every probe moves memory up or core down inside the range, the chosen point beats the start in
five probes), `a_refused_probe_backs_that_knob_off_for_good`, `each_goal_picks_its_point` (and the £/day formula),
`powertask::tests` (the `lmc`/`rmc` verbs reach nvidia-smi as `-lmc m,m` and `-rmc`), `sweep::tests` (the helper
scripts carry them), `relay/test/ember.test.mjs` (climb records aggregate into a prior with the memory clock).
Owed: the measured comparison on PC 1 (one climb per card against run 5's ladder rows, no prompt through the
Power Helper), the temperature-band trigger, NVAPI/nvidia-settings for cards whose driver refuses `-lmc`.
## 7a. One administrator approval, ever (0.3.13; the project lead, 6 October 2026, 11:50 UTC)
