On an RTX 4090 the reference check alone flagged all 294.Release 0.4.2: Self-test faults shaped like NVIDIA's gate-level measurementshttps://github.com/tech4biz-yasha/ai-chip-integrity/releases/tag/v0.4.22026-10-15T00:00:00ZSelf-test faults shaped like NVIDIA's gate-level measurementsWhen ECC is off, the memory error counters cannot see anythinghttps://chipintegrity.org/findings/ecc-off.html2026-10-11T00:00:00ZTwo rented cards ran with ECC switched off, so their counters could not move. The tester now says so instead of calling them quiet.Release 0.4.1: The ecc-off verdict, faster exact references, and the RTX 4090 and RTX A5000 rowshttps://github.com/tech4biz-yasha/ai-chip-integrity/releases/tag/v0.4.12026-10-11T00:00:00ZThe ecc-off verdict, faster exact references, and the RTX 4090 and RTX A5000 rowsBF16 matrix multiplies on Intel AMX treat tiny inputs as zerohttps://chipintegrity.org/findings/intel-amx-bf16.html2026-10-10T00:00:00ZAbove 16 × 16 × 16, BF16 matrix multiplies on AMX CPUs treat subnormal inputs as zero, whatever set_flush_denormal says.Release 0.4.0: Six probes, one command, OCP Test and Validation outputhttps://github.com/tech4biz-yasha/ai-chip-integrity/releases/tag/v0.4.02026-10-10T00:00:00ZSix probes, one command, OCP Test and Validation output
