📋 HOST-REPORTED TELEMETRY · SPDM NOT SUPPORTED

Host-reported software telemetry only. This architecture does not support hardware SPDM attestation; results are not silicon-signed.

Point-in-time software telemetry at test completion; no physical warranty, shipping warranty, silicon lifespan guarantee, or physical board seal. An issuer Ed25519 signature does not establish a silicon root-of-trust signature.

WHAT THIS REPORT MEANS

  • Host & driver: Telemetry is driver-reported at test time. Consumer GPUs lack hardware SPDM attestation; this report does not detect OS/driver-level spoofing on a compromised host.
  • Performance: Bandwidth and error counts reflect empirical stress-test throughput, not guaranteed silicon lifespan or permanent health.
  • Point in time: This is a baseline snapshot at test completion, not a shipping warranty or physical board seal. Buyers should rerun the runner on receipt to verify against baseline.

Recorded coverage: Host benchmark bandwidth · Recorded temperature telemetry · Reported memory errors · Reported PCIe counters. Coverage describes report fields, not independently witnessed tests.

Fields that could not be verified

  • Current certificate validity is not established
  • Vendor-root hardware identity / SPDM
  • Serial authenticity beyond driver telemetry
  • VBIOS vendor authenticity beyond recorded hash
  • Ownership and physical condition
  • Remaining lifespan
  • Unrecorded load duration, benchmark version and full node topology
