MODEL-SPECIFIC SERVICE
NVIDIA A100 40GB / 80GB GPU Repair
Board-level diagnosis and repair for A100 40GB and A100 80GB, available in both PCIe card and SXM4 module form. We assess power faults, initialization failures, memory errors and instability under load.

SUPPORTED A100 VERSIONS
40GB and 80GB: identify the complete assembly
| GPU variant | Memory | Form factor | Assessment requirements |
|---|---|---|---|
| A100 40GB PCIe | 40GB HBM2 | PCIe card | PCIe host and cooling matched to the exact board. |
| A100 80GB PCIe | 80GB HBM2e | PCIe card | 80GB-specific assembly and compatible test configuration. |
| A100 40GB SXM4 | 40GB HBM2 | SXM4 module | Compatible SXM4 carrier, power and cooling arrangement. |
| A100 80GB SXM4 | 80GB HBM2e | SXM4 module | 80GB SXM4 assembly, carrier and package compatibility review. |
The 80GB version has twice the memory capacity of the 40GB version. A100 40GB uses HBM2; A100 80GB uses HBM2e. PCIe and SXM4 are separate physical assemblies with different host and cooling arrangements.
A repair does not imply a 40GB-to-80GB conversion. Package, PCB and replacement-part compatibility are checked against the exact device.
ASSESSMENT ROUTE
How we approach the fault
- 01
Confirm the assembly
Match the 40GB or 80GB version, PCIe or SXM4 form factor, and compatible host setup.
- 02
Assess the fault
Review board condition, electrical findings and platform tests to define the repair scope.
- 03
Repair and validate
Complete approved work, then document the relevant memory, link and load-test results.
COMMON ISSUES
What we assess
| Reported symptom | Assessment focus |
|---|---|
| Not detected / initialization failure | Power delivery, startup behavior and host or carrier compatibility. |
| Driver timeout / dropped device | Error logs, software configuration, temperature and power under load. |
| Memory-related errors | Repeatable memory tests, supporting circuits and GPU/HBM package condition. |
| Reduced link performance | PCIe or NVLink behavior and the associated slot, carrier or host. |
REPAIR BOUNDARIES
The assembly determines the scope
A100 PCIe cards and SXM4 modules require different host platforms and cooling arrangements. HBM is part of the GPU package assembly; an HBM-related report does not automatically justify ordinary memory-chip replacement.
