NVIDIA A40 48 GB GDDR6 Accelerator

The NVIDIA A40 is a dual-slot PCIe 4.0 x16 accelerator card equipped with 48 GB of GDDR6 memory. It uses a passive cooler and is built for dense server deployments where external airflow handles thermal management.

Suited for GPU compute clusters

This card fits servers that can supply forced air across a passive heatsink and provide a PCIe 4.0 x16 slot. It is not for workstations or enclosures that rely on active fan cooling on the card itself, nor for builds needing display outputs.

48 GB frame buffer for large models and datasets

The 48 GB GDDR6 capacity lets you hold sizable neural networks and batch data in local memory. Workloads that exceed this frame buffer will need multi-GPU scaling or host memory offload, which adds latency.

Highlights

  • 48 GB GDDR6 memory enables large-model training
  • PCI Express 4.0 x16 host interface delivers high-throughput data transfer
  • Passive cooler design suits dense server deployments
  • Dual-slot form factor fits standard rackmount chassis
  • New condition ensures full factory specifications

Questions about this item

Do I need a server chassis with enough airflow for a dual-slot passive cooler?

Yes, the card uses a passive cooler and relies on the chassis fans to move air across its heatsink, so the enclosure must provide sufficient directed airflow.

Will the PCI Express 4.0 x16 host interface operate in a PCIe 3.0 slot?

The interface is backward compatible and will run at PCIe 3.0 speeds when installed in a 3.0 slot, though bandwidth is reduced compared to a 4.0 connection.

How can I confirm the 48 GB GDDR6 memory is recognised after installation?

Run nvidia-smi or check the system BIOS; both will report 48 GB of GDDR6 memory if the card is seated correctly and the driver loads.
