H100

Overview

H100 appears in this dataset mainly as a high-end Nvidia accelerator sold in PCIe, NVL, and SXM5-based Exxact systems. Tickets cluster around GPU detection and stability, firmware/tooling access, NVLink or fabric expectations, platform compatibility, thermal or acoustic tuning, and basic ownership questions such as warranty or power requirements.

Known Issues

• GPU Hardware Failure (~18 tickets) - falling off bus, uncorrectable ECC, driver-visible but unusable cards, and workload-triggered crashes. Examples: #11870, #17919, #19864, #20502, #24006.
• System Boot Failure (~8 tickets) - H100 systems hanging in BIOS, losing PCIe devices, or failing to reboot cleanly. Examples: #16288, #17521, #18391, #25314, #40999.
• BIOS Firmware Update (~6 tickets) - BIOS, BMC, GPU firmware, or nvflash access questions, sometimes tied to stability or feature enablement. Examples: #18391, #22548, #22691, #25938, #40999.
• fan failure (~3 tickets) - aggressive acoustic profiles or system-fan behavior in dense H100 servers. Examples: #20894, #26130, #39487.
• pcie device detection (~7 tickets) - PCIe card visibility, lane/topology confusion, or mixed-device compatibility around H100 platforms. Examples: #11163, #24388, #24912, #26890, #28339.

Common Questions

• Why does the H100 show in BIOS or lspci but not in nvidia-smi? This usually led to deeper PCIe or hardware validation, driver cross-checks, and sometimes GPU RMA when the fault followed the card. Examples: #18827, #18843, #24006, #40135.
• What should we check when an H100 falls off the bus or crashes under load? Tickets commonly worked through reseat, slot-swap, cross-OS checks, ECC/error counts, BIOS settings, and platform firmware before deciding on RMA. Examples: #11870, #12479, #17443, #19864, #21737.
• Do PCIe H100 systems need Fabric Manager or NVLink accessories? Support repeatedly clarified that PCIe H100 behavior differs from SXM/NVSwitch expectations, and that NVLink bridge/fabric assumptions are easy to get wrong. Examples: #17864, #22256, #26733.
• Can H100 systems mix with older GPUs or extra PCIe devices? Compatibility depended on cabling, chassis support, power, and slot topology, not just whether the cards physically fit. Examples: #11840, #24388, #26890, #28339.
• How do we get GPU firmware or nvflash? Several customers needed vendor-routed access rather than a direct Exxact download, especially for H100 firmware tooling. Examples: #22548, #22691, #25938.
• Why are H100 servers loud? Dense H100 systems often ship with conservative fan behavior for thermal headroom, and some tickets asked about tuning rather than failure. Examples: #20894, #26130, #39487.
• What warranty applies to an H100 purchased through Exxact? Customers asked both about standalone GPU coverage and system-attached H100 warranty terms. Examples: #11721, #21876, #28625.

Related Products

• A100 - commonly compared with H100 for NVLink, mixed-GPU compatibility, and upgrade questions (#17864, #26890).
• H100 NVL - often confused with standard PCIe H100 behavior, especially around display output, NVLink, and platform expectations (#25314, #26733).
• H100 SXM5 systems - firmware and fabric questions differ from PCIe cards because the platform and tooling path are different (#25938, #22256).
• L40S / other PCIe accelerators - similar PCIe installation expectations, but different cooling, cabling, and firmware assumptions (#11840, #28339).
