Hardware QA & Silicon Stress Testing

Discovery, Stress Testing & QC. Full confidence before you price a single device.

ITAD margins depend on accurate device assessment. A missed dead pixel, thermal throttling under load, or a degraded battery costs real margin after resale. reCore runs automated hardware discovery, multi-core silicon stress burn-in, and technician QC suites so you know the exact condition of every unit.

Silicon Stress & Burn-In Engines
Catch hardware instability under full thermal load.

Cosmetic checks and idle specs don't reveal failing silicon. reCore includes industrial-grade multi-process burn-in engines to test CPU calculation integrity, memory bit stability, and storage throughput under sustained load.

Multi-Process CPU Burn-In

Spawns worker processes per logical core executing deterministic ALU and FPU math. Each round is validated with a rolling 64-bit SHA-256 digest in O(1) time. Detects calculation corruption, thermal throttling (<60% peak clock), and fan stalls (>70°C).

RAM Moving Inversion Engine

Allocates up to 80% of available memory and cycles through 0xA5 bitwise inversion patterns with 4KiB page-address stride checking. Detects single-bit flips and memory controller faults while guaranteeing 512MB OS safety headroom.

Direct-to-Media Storage Burn-In

Non-destructive filesystem I/O burn-in with direct OS cache-bypass (FILE_FLAG_NO_BUFFERING on Windows, POSIX_FADV_DONTNEED on Linux). Verifies byte-for-byte read-back patterns and benchmarks real sustained MB/s throughput.

Automated Hardware Discovery
Zero technician effort required.

These queries execute programmatically via WMI, SMBIOS, and direct hardware interfaces, reporting deep telemetry with no human intervention.

Battery Health & Chemistry

Reads design capacity, current capacity, cycle count, charge rate, and cell chemistry. Calculates health percentage and wear degradation against configurable grade thresholds.

Storage SMART & Wear

Pulls comprehensive SMART attributes across NVMe, SATA, and SAS drives. Reports reallocated sectors, wear level percentage, power-on hours, and controller error counts.

EDID Display Parsing

Reads panel vendor, native resolution, refresh rate (60Hz–240Hz), bit depth, color space, and HDR capability directly from the display bus.

DIMM-Level Memory Analysis

Detects installed RAM modules, slot configuration, memory type (DDR4/DDR5), speed (MHz), timings, rank, and serial numbers per physical stick.

GPU & PCIe Topology

Identifies integrated and discrete GPU models, dedicated VRAM capacity, PCIe link width, and driver versions.

Thermal & Fan Sensors

Continuously polls thermal zone diodes and fan RPM sensors to verify cooling assembly integrity and detect thermal throttling.

Interactive tests
Human verification when it matters.

These tests require technician interaction. The client application guides the technician through each check with clear visual prompts and records the results.

01
Display analysis

Cycles through test patterns to detect dead pixels, check color accuracy, and assess backlight uniformity. Touchscreen presence is flagged where detected.

02
Keyboard mapping

Every key is individually registered against a virtual layout. Missing, stuck, or intermittent keys are flagged. Backlight function is tested where applicable.

03
Port verification

Guided checklist covering USB ports (type A, C), HDMI, DisplayPort, Ethernet, SD card reader, headphone jack, and power jack for connectivity.

04
Camera test

Captures test frames from the webcam with live preview. Supports device switching for multi-camera setups.

05
Audio system

Plays left/right speaker test tones and records a sample through the microphone for playback verification.

06
Trackpad test

Verifies click, scroll, and cursor tracking. Detects cursor skipping and multi-touch response.

Manual inspections
Eyes on every detail.

Some defects can only be caught by a person. reCore guides the technician through a structured checklist with clear pass/fail criteria for each item. This eliminates the inconsistency of free-form notes and ensures every technician evaluates the same things.

Security scanning
MDM locks, firmware, and activation.

Before committing processing time and wipe credits to a device, reCore checks for management profiles and firmware locks that could prevent resale entirely.

MDM profile detection. Enterprise management profiles from Intune, MobileIron, VMware Workspace ONE, SCCM, MaaS360, ManageEngine, and others are identified so they can be removed through proper channels before the device enters the resale pipeline.

Absolute/Computrace detection. Devices with persistence agents embedded in firmware are flagged. These agents survive OS reinstallation and can remotely lock or wipe the device after sale if not properly deactivated.

BIOS/UEFI password check. Devices with firmware passwords that would prevent OS reinstallation or normal boot are flagged for resolution before processing continues.

Azure AD and Autopilot detection. Devices enrolled in Azure Active Directory or Windows Autopilot are identified so IT administrators can remove them from their tenant before the device is resold.

How results flow
From device to dashboard instantly.

As each test completes, results sync to the cloud dashboard via WebSocket. There is no batch upload delay. The dashboard shows test progress as it happens. If the device loses connectivity mid-session, results queue locally on the client and upload automatically when the connection restores. No data is lost.

Each result includes the test name, outcome (pass/fail/warning), duration in seconds, a summary score, any error messages, and optional technician notes. These roll up into the device's overall diagnostic profile, which directly informs the automated grading calculation downstream.
