A dead accelerator isn't scrap — it's stranded capital. EON Digital provides board-level data center GPU repair and validation for NVIDIA A100 and H100 cards and the HPC systems they live in. Every card leaves with a per-serial validation report, so you know exactly what you own.
We repair and validate the NVIDIA data center accelerators that power AI and HPC workloads — in PCIe and SXM form factors.
NVIDIA A100 repair in both PCIe and SXM4 form factors, 40GB and 80GB. Board-level diagnosis of power delivery, thermal, and interconnect faults on Ampere data center cards — the workhorse GPU of AI training clusters.
NVIDIA H100 repair for PCIe and SXM5 cards. Hopper-generation accelerators fail the same ways Ampere does — VRM stages, input power, connectors, thermal contact — and the same board-level discipline brings them back.
Beyond individual cards: the GPU servers and HPC systems they live in. Fault isolation across the card, the slot, the power path, and the platform — because "the GPU is dead" isn't always the GPU.
GPU not detected in nvidia-smi. Card falls off the bus under load. Xid errors and uncorrectable ECC faults. No power-on, fans at full speed with no output, thermal shutdowns under sustained load, degraded NVLink or PCIe link speeds, and cards that pass a quick check but fail real training workloads. If your A100 or H100 is doing any of these, it's a candidate for diagnosis — symptoms like these typically trace to board-level faults, not the GPU die itself.
Whether a card is down, unproven, or fresh off the secondary market — the goal is the same: know its true condition, and get it earning.
Full health verification of working or unknown-condition cards: diagnostics, stress testing, thermal behavior, memory and interconnect checks, and benchmark comparison against known-good baselines. Deploy with confidence — or negotiate with evidence.
Board-level diagnosis and component-level repair of failed accelerators — power delivery, thermal, connector, and board faults. The same microsoldering discipline behind tens of thousands of repaired hashboards, applied to enterprise silicon.
Fleet-level failure analysis: why cards are failing, whether it's environmental (power, cooling, dust), workload-related, or a bad batch — with documentation you can take to your facility team or your vendor.
Documented at every step — the same discipline as our miner repair line, adapted to enterprise GPUs.
Serial-level intake with chain-of-custody documentation that works with your existing R2 certification process. Visual and thermal-camera inspection, and a record of as-received condition before anything is powered on.
Industry-standard GPU diagnostics (including NVIDIA DCGM-based test suites), fault isolation across power stages, memory, and PCIe/NVLink interconnects.
Component-level rework where the fault is repairable — full uniform preheat, controlled thermal profiles, no shortcuts. Enterprise boards get the careful path, always.
Sustained load testing under real thermal conditions — compute stress, memory exercise, and power-draw monitoring over time, not a five-minute smoke test.
Performance benchmarked against known-good baselines for the same model — compute throughput, memory bandwidth, link speeds, thermals. A card either meets spec or it doesn't ship as passed.
A per-serial validation report — condition in, work performed, test results, final status — with every card. Documentation formatted to support your R2 and IT asset disposition workflows.
The same honesty we're known for in miner repair: we fix what's fixable, and we tell you plainly what isn't — with the diagnosis to back it up either way.
Buying A100s or H100s on the secondary market? Validate before you deploy. A per-serial validation report tells you what you actually bought — before it's racked, and before the return window closes.
Ask About ValidationStraight answers to the questions we get most from data centers, ITAD companies, and secondary-market buyers.
Usually, yes. With replacement cards running well into five figures, even a thorough diagnosis plus board-level repair costs a small fraction of replacement. The most common A100 and H100 failures are in power delivery, thermal contact, and connectors — repairable board-level faults — not in the GPU die or HBM stacks.
Yes — the service is built for IT asset disposition companies and secondary-market sellers who need failed inventory turned into sellable, validated inventory. Per-serial validation reports document condition and test results — paperwork that supports your R2 process and gives buyers confidence.
Email us first and we'll send intake instructions. Cards ship to our Upstate New York facility; every serial is logged at intake with as-received condition documented before anything is powered on. We handle single cards through pallet-scale lots.
Yes — repairs carry a 90-day warranty, and no card ships as "passed" unless it meets known-good performance baselines under sustained load. EON Digital is an independent repair facility, not affiliated with or authorized by NVIDIA.
