Supported H100 Models
H100 SXM5
- 80GB HBM3 memory (5 stacks)
- NVLink 4.0 (18 links, 900 GB/s)
- 700W TDP — common thermal cycling failures
- Used in DGX H100, HGX H100 baseboard systems
H100 PCIe
- 80GB HBM3 memory
- PCIe Gen5 x16 interface
- 350W TDP — lower thermal stress, more connector issues
- Standard server rack deployments
Common H100 Failures We Fix
Component-level diagnostics. We find what actually broke and fix it. No board swaps.
HBM3 Stack Failures
ECC errors, bandwidth degradation, or complete HBM3 module death. BGA rework to replace individual stacks on the H100 interposer.
VRM Damage
Blown MOSFETs, dead power stages, voltage regulator faults. The H100 SXM5's 700W power envelope pushes VRM components hard. Shows up as intermittent crashes or no-post.
Thermal Damage
Thermal cycling at 700W cracks solder joints and delaminates substrates. Diagnostic imaging locates fractures, then reflow or reball the affected area.
PCB Trace Breaks
Cracked or severed traces from mechanical stress or corrosion. Micro-soldering and trace jumper repair under microscope on the H100's dense multi-layer PCB.
NVLink Faults
NVLink 4.0 bridge failures, lane degradation, and NVSwitch communication errors. Critical for multi-GPU H100 SXM5 deployments running distributed training.
H100: Repair vs Replace
NVIDIA doesn't repair H100s. A replacement costs $25K+ and takes weeks. Here's the math.
| Repair with GPU Repair Lab | Buy New H100 | |
|---|---|---|
| Cost | $2,000 - $8,000 | $25,000 - $40,000+ |
| Timeline | 1-2 weeks | 2-4 weeks (H100) / 3-6 months (H200) |
| Warranty | 90-day repair warranty | Standard NVIDIA warranty |
| Availability | Immediate — ship your unit | Subject to supply / allocation |
Even if you're ordering a replacement H100, repairing the dead one gives you a working spare or a board you can resell.

H100 Repair FAQ
How much does H100 repair cost compared to buying a replacement?
H100 board-level repair typically runs $2,000-$8,000 depending on the failure type. HBM3 stack rework is at the higher end, connector repairs at the lower end. Compare that to $25,000-$40,000+ for a new H100. You get an exact quote after diagnostics.
Can you repair both H100 SXM5 and H100 PCIe variants?
Yes. We repair both H100 SXM5 and H100 PCIe boards. The failure modes differ slightly between form factors—SXM5 boards see more thermal cycling damage from high-density installations, while PCIe cards more often have connector and mechanical stress issues. We handle both.
What is the success rate for H100 HBM3 memory repairs?
HBM3 stack replacement via BGA rework has a high success rate when the underlying substrate and interposer are intact. During diagnostics, we assess whether the HBM failure is isolated to the memory stack or if there is deeper substrate damage. If the board is not repairable, you pay nothing for the repair.
Do you test H100 boards after repair?
Every repaired H100 goes through a full burn-in test cycle including memory stress tests, compute workload validation, and NVLink connectivity checks (for SXM5). You receive a detailed test report with the repaired board. All repairs carry a 90-day warranty.
