CleanSpec Lab Validation Overview

At CleanSpec Lab, every computer is inspected, tested, and validated according to its intended use. Not every system requires the same level of testing, but every system receives a documented validation process appropriate for its hardware and expected workload.

Level 1 – CleanSpec System Validation

Applies to: General desktop computers not eligible for OCCT certification.

Validation Includes

• BIOS-level hardware diagnostics (where supported)

  • Processor

  • Memory

  • Storage

• Systems whose BIOS does not include processor diagnostics (common on some older platforms) receive all available built-in hardware diagnostics.

• Windows installation and activation verification

• Driver installation and verification

• Multiple shutdown/restart validation

• Wi-Fi and Bluetooth verification (when equipped)

• USB, audio, and display verification

• Storage health verification using Hard Disk Sentinel

Storage Requirements

Every storage device is evaluated using Hard Disk Sentinel.

Drives exhibiting poor health or reliability indicators are removed from service. Storage health is disclosed in the listing when appropriate.

Level 2 – CleanSpec Bronze Core Certification

Applies to: Productivity systems and entry-level workstations.

Includes everything in CleanSpec System Validation plus:

• OCCT CPU Stability

• OCCT Memory Stability

• Extended thermal monitoring

• CPU package temperature verification

• System stability under sustained processor and memory load

Bronze Core Certification validates the platform's ability to sustain demanding productivity workloads.

This certification does not include the OCCT 3D Adaptive graphics stress segment.

Level 3 – CleanSpec Bronze System Certification

Applies to: Professional workstations and systems intended for sustained graphics workloads.

Includes everything in Bronze Core Certification plus:

• OCCT 3D Adaptive stress testing

• Combined CPU, memory, and GPU workload validation

• Full-system thermal validation

• Graphics subsystem stability verification

Bronze System Certification represents CleanSpec Lab's highest currently published validation standard and confirms successful completion of the complete OCCT Bronze validation protocol.

Why Different Validation Levels?

A computer should be tested according to its intended purpose.

An office desktop, productivity workstation, and professional graphics workstation place very different demands on their hardware.

Rather than applying a one-size-fits-all approach, CleanSpec Lab publishes the exact validation level each computer has successfully completed, allowing customers to understand precisely how their system was tested before it arrives.
