HOW IT WORKS

Burn it in, then prove it.

01
Seat the cards

Cards install into the bench; the rig detects family and configures itself accordingly.

02
Burn-in

Sustained load runs against the published utilization and thermal thresholds.

03
Live telemetry

nvidia-smi telemetry is sampled through the run rather than read once at the end.

04
Verify

Each card either meets the thresholds or is recorded as FAIL or QUARANTINED.

05
Certificate issued

Apex software issues a certificate per GPU serial into the lot custody log.

THE RECORD

Apex generates the record.

On the UGPUTC-SXM4, the certificate and custody log are produced by Apex software. That makes the record Apex’s product and Apex’s liability, held to the Apex Chain-of-Custody Specification.

WHAT THE RECORD CARRIES
—Per-module certificate + lot custody log
—Primary identifier: Module serial + HGX baseboard serial — read from the device, never operator-typed
—Custody events: intake, process start, process end, verification, disposition
—Method, tool and version, result (PASS · FAIL · QUARANTINED) and the accountable operator
WHAT THE RECORD CARRIES
—Every asset identified at intake by serial and recorded through to a documented disposition
—Method, tool and version, operator, result and timestamp on every record
—Written to your own NAS in a structured, exportable format
—Built to satisfy the documentation NIST SP 800-88 Rev. 2 expects
Every Apex-generated record is held to the same specification across the Group A machines. See the full custody model
