MODEL-SPECIFIC SERVICE
NVIDIA H100 80GB GPU Repair
Fault isolation for H100 80GB PCIe cards and H100 80GB SXM5 modules, with attention to power delivery, device recognition, memory behavior and platform interconnects.
H100 80GB · PCIe cards / SXM5 modules
SUPPORTED H100 VERSIONS
80GB PCIe and 80GB SXM5
| GPU variant | Memory | Form factor | Assessment requirements |
|---|---|---|---|
| H100 80GB PCIe | 80GB HBM2e | PCIe card | PCIe assembly, host power and system cooling. |
| H100 80GB SXM5 | 80GB HBM3 | SXM5 module | Compatible SXM5 carrier, power and cooling arrangement. |
The two 80GB versions use different memory and board configurations: HBM2e on the PCIe card and HBM3 on the SXM5 module. The test platform and replacement parts must match the exact assembly.
The 40GB service listing applies to A100, not these H100 models. H100 NVL is a separate 94GB-per-GPU variant; contact us to confirm its assessment scope before sending hardware.
ASSESSMENT ROUTE
How we approach the fault
- 01
Match the configuration
Confirm the PCIe or SXM5 assembly, board revision, carrier and cooling requirements.
- 02
Localize the fault
Compare electrical findings and supported platform tests before choosing component work.
- 03
Verify the outcome
Check startup, memory and supported interconnect behavior, followed by load testing.
COMMON ISSUES
What we assess
| Reported symptom | Assessment focus |
|---|---|
| GPU does not initialize | Board condition, power delivery and behavior in a compatible host. |
| Abnormal startup / power protection | The affected power circuit and supporting components. |
| Repeatable load failures | Logs, cooling, power and stability in the agreed test configuration. |
| Interconnect errors | PCIe or NVLink behavior and the carrier or host connection. |
REPAIR BOUNDARIES
The assembly determines the scope
SXM5 and PCIe versions require different test arrangements. Diagnosis, replacement parts and validation must match the specific board revision and host platform.
