## Key findings

**170HX vs A100 (empirically confirmed, 2 physical cards):**
- ALL 9 speed select fuses at `0x5` (max throttle) — CMP-exclusive, 0x0 on all datacenter/professional
- `SKED_UNK54` = `0x60000600` pre-driver (first non-zero in 13 cards) — cleared by driver at GR init, pre-init fuse state only
- `SM_ISSUE_RATE_MODIFIER` = `0x5` on BOTH A100 and 170HX — NOT the throttle register. Host-writable but no perf change when zeroed
- NVLink fuse-killed: `FUSE_NVLINK_DIS` = `0x7` (all groups). Silicon intact (`DEFECTIVE`=0x0), just fuse-gated
- PCIe double-locked: `FUSE_PCIE_GEN23_DIS` = `0x1` (fuse) + devinit (5 bytes). Firmware-only patch insufficient
- Memory: `FBPA_CFG1_BROADCAST` = `0x02449000` (nerfed). No half-capacity fusing (`FUSE_HALF_FBPA_EN`=0x0)
- `FUSE_FEAT_OVR_DIS` = `0x0` on ALL cards — override path architecturally available (needs Falcon HS)
- **`FUSE_EN_SW_OVERRIDE` (0x820040) = `0x0` on 170HX + all A100 + Drive A100, `0x1` on all consumer/ES** — CTRL_OPT override mechanism is **disabled at the fuse level on 170HX and Drive A100**. The 25-entry CTRL_OPT table in the unsigned FwSec tail is inert on these cards. `FUSE_DIS_SW_OVR` = `0x1` on all cards (likely locks EN_SW_OVERRIDE at its current value, but interpretation requires write probe). See `docs/ctrl-opt-hypothesis-test-plan.md`.
- **Host-level register write approach CONFIRMED DEAD for compute unlock**

**Cross-unit 170HX comparison (Cab vs Own, both 10GB 0x2082):**
- 107 of 120 registers identical. All restriction fuses match exactly (speed select, PCIe, NVLink, CFG1, SKU ID)
- 13 differences are all per-unit die binning: floorsweep masks (`GPC_DISABLE`, `FBP_DISABLE`, `FBPA_DISABLE`), per-unit SM speed override encoding (`FEAT_OVR_SM_SPD`), HBM silicon ID (`I1500_DATA/SHADOW_WDR`)
- Both have 20 active FBPAs (10 FBPs × 2) but disabled set differs: Own=FBPA{0,1,6,7}, Cab=FBPA{14,15,16,17}
- `FUSE_PCIE_DEVIDB` = `0x20C2` on both — both 10GB cards carry the 8GB device ID as fuse B
- Confirms: restriction fuses are product-line (identical across units), floorsweep fuses are per-die binning

**Cross-Ampere patterns:**
- Speed select (FMLA32 + IMLA4): `0x1` on ALL consumer GeForce, `0x0` on ALL professional/datacenter, `0x5` on CMP
- ECC fuse: `0x1` on ALL professional/datacenter, `0x0` on ALL consumer + CMP
- NVLink disable: `0x7` on 170HX, `0x1` on RTX 3080/3080Ti, `0x0` on all others
- `FUSE_MEM_LOCKED` = `0x1` on ALL cards — memory config locked at runtime
- A16 has smaller BAR0 (256KB), most fuse registers unreadable

**Drive A100 32GB (GA100-550F-A1, 2× PG199, probed 2026-05-31):**
- ALL speed select fuses at `0x0` — NO throttle. `FEATURE_READOUT_1` = `0x0` confirms no active throttle
- NVLink fuse-killed: `STATUS_OPT_NVLINK` = `0x7` (same as 170HX)
- `EN_SW_OVERRIDE` = `0x0`, `DIS_SW_OVR` = `0x1` — CTRL_OPT disabled, same as datacenter A100
- Floorsweep: `STATUS_OPT_FBPA` = `0x00C0330C` (16 of 24 active, vs 170HX's 20)
- `STATUS_OPT_GPC` differs per unit: GPU0=`0x44`, GPU1=`0x06` (per-die binning)
- `FEATURE_OVERRIDE_PLM` = `0xFFFFFF8F` (L3-only, same as all GA100)

**Pending:** erhaede ES A100 (thermal event 2026-05-05, status uncertain)
