Query the authoritative registry to validate hardware authenticity.
Without independent verification, buying high-end hardware is a gamble. Assurd helps uncover what a basic boot test can miss.
Standard boot tests don't reveal dried thermal paste or degraded memory pads. Cards that idle fine can hit 105°C+ hotspot temperatures under sustained load.
A basic inspection can miss this.
A power-on test proves a GPU turns on. A benchmark proves it can run a benchmark. Assurd investigates what those checks leave unverified—and records the evidence behind the verdict.
Liquid ingress and microscopic corrosion may leave no obvious surface clue, yet create leakage paths and delayed failures.
The PCB is graded under a bench lamp, the PCIe fingers and power connectors under magnification, and the input rails are diode-checked for shorts.
No power is applied until the PCB, cooler and power connectors are inspected and the rails are resistance-checked.
Every certified unit passes all five phases. No partial certifications are issued.

Every audit is executed on zero-bottleneck test benches backed by calibrated instruments and fixed telemetry standards.
A current desktop CPU with fixed boost limits, 32 GB of DDR5 and a 360 mm AIO keeps the CPU from limiting the GPU during sustained load, so the measurement is of the GPU.
A bench multimeter (Uni-T UT61B+ class, 0.1 Ω resolution) for diode checks and rail-to-ground resistance, an EZP2023+ SPI flash programmer to read raw VBIOS images straight from the chip, a hardware board-power monitor and a radiometric thermal camera.
Open-air test benches with ambient temperature logged on every sample keep conditions the same from audit to audit. What still varies from run to run is measured and shown on the certificate, not assumed away.

Transparent pricing. Fully insured two-way logistics included. No hidden costs.
The core baseline audit. Built for mainstream and mid-range GPUs entering the secondary market.
Full-spectrum stress testing for high-value silicon, modern 4K gaming cards, and workstation accelerators.
We are scaling our verified testing footprint into regional markets through authorized lab facilities. Deploy our standardized test bench SOPs, manage local unit ingestion, and upload telemetry directly to our network.
Track regional hardware logistics, log physical intake data, and stream raw telemetry profiles directly from your test bench into our cloud architecture.
While lab facilities execute the rigorous 5-phase forensic audit locally, cryptographic signing and official certificate minting remain strictly governed by HQ labs.
Quick answers to our most common operational queries.
The physics and methods behind every measurement on an Assurd certificate, and the market gaps they are designed to close, written by the lab.
Rising prices for new devices are pushing Indian buyers to refurbished phones, and that market is formalising around certified programmes. Graphics cards face the same price pressure with no way for a buyer to see a card's condition. How a signed certificate is designed to change that.
How a Premium Assurd certificate turns one calibrated recording into an A-weighted equivalent sound level under load: decibels from first principles, the A-weighting curve, the 94 dB calibrator tone, the 50 cm geometry, the 6 dB noise-floor rule and tonal peaks.
What exactly an Assurd certificate signature covers, why the certificate is signed as canonical JSON bytes, how the ES256 key in Cloud KMS signs it, and how to check one yourself: in the browser, or offline with OpenSSL and no trust in this website.
