Our GPU Repair Services Include:
- Advanced Diagnostics Process: Fault finding using specialist diagnostic software with electrical analysis tools and schematics. Thermal camera inspection to identify hotspots instantly. Rail analysis (12V, 5V, 1.8V, Vcore). Short circuit detection and isolation. Component-level fault tracing (VRM, memory, GPU core). Oscilloscope and electrical testing where required.
-
12V-2×6 & 12VHPWR Connector Restoration: Professional replacement of melted or oxidized power headers using high-conductivity H++ standards. We repair burnt connectors, damaged power input stages and power delivery faults caused by connector failure.
-
PCIe 5.0 Signal Integrity: Fixing intermittent “No Post” issues and VGA LED errors common in modern high-bandwidth slots.
-
GDDR7 & GDDR6X Memory Reballing: Specialist overhaul for artifacting or memory-controller failures on high-density VRAM modules.
-
Micro-Soldering & BGA Rework: Surgical repair of multi-phase VRMs, including complex trace reconstruction and pad restoration. We provide professional BGA reballing for GPU cores and memory modules, alongside precision replacement of fine-pitch SMD components under high-level magnification.
-
Custom Modifications & Enhancements: BIOS updates, fan curve adjustments, and other specialist upgrades.
Post-Repair Testing & Validation
Every GPU we repair undergoes a structured validation process to ensure full electrical stability, thermal integrity, and real-world reliability.
This includes:
- Full POST and driver enumeration verification
- Multi-stage load testing using 3D rendering workloads and benchmarking tools (e.g. 3DMark, Unigine)
- Extended stability testing under sustained GPU and VRAM load conditions
- Power delivery validation under dynamic load to confirm stable operation of all voltage rails
- Thermal analysis under stress to verify correct heat transfer and cooling performance
- Memory integrity checks to detect artefacts, errors, or instability in GDDR modules
Only once a GPU remains stable across all test stages is it approved for return. In selected cases, we also provide a short stress-test recording demonstrating stable operation under load.
