PLATFORM AND SOFTWARE
- Passive cooling requires qualified server airflow
- CPU 8-pin power connector; verify the server cable pinout
- Physical display outputs are disabled by default and require configuration
- Does not support MIG
- Confirm the exact driver, CUDA runtime, framework and server operating-system combination before purchase
- Historical minimum software versions in the product brief do not establish current release qualification
- vGPU and enterprise software entitlements must be checked separately from ownership of the card
Maximum board rating, not complete system consumption
INTERCONNECT
PCIe Gen4
Datasheet labels 31.5 GB/s bidirectional; direction convention is ambiguous, so no normalized numeric rate is asserted
NVLink
112.5 GB/s. Manufacturer bidirectional rating; compatible bridge and pair topology required
