NVIDIA Tesla K40 12GB GDDR5 PCIe Server GPU Accelerator

This 12 GB GDDR5 accelerator is for parallel-computing projects built around NVIDIA's Kepler platform, not for connecting a monitor. I would check your server, cooling and software requirements before choosing it for a home lab or research system. It is a legacy compute card, not a drop-in upgrade for current AI software.

Product Facts

• Brand / model: NVIDIA Tesla K40, passive server accelerator.
• GPU: Kepler GK110B with 2,880 CUDA cores.
• Memory: 12 GB GDDR5, 384-bit interface, 288 GB/s bandwidth. ECC uses part of this capacity; NVIDIA specifies approximately 11.25 GB available with ECC enabled.
• Interface / size: PCI Express Gen3 x16, dual-slot, approximately 267 mm long × 111.15 mm high.
• Display outputs: None.
• Board power: 235 W specification; passive heatsink requires suitable forced chassis airflow.

Plan the system before installation

The board has 8-pin and 6-pin auxiliary PCI Express power headers. Follow the K40 board specification and your server manufacturer's qualified cabling instructions; do not assume another Tesla model uses the same wiring. Verify slot clearance, power capacity, firmware resource allocation and cooling with your system manufacturer. Shut down and disconnect system power before installation, and use appropriate anti-static handling.

NVIDIA lists CUDA 11.x as the last toolkit family and R470 as the last driver branch for this Kepler generation. Check the exact operating system, driver, toolkit and application combination before buying; current CUDA releases and current machine-learning packages must not be assumed compatible. This is not a fan-cooled desktop graphics card, and it must not be operated without adequate forced airflow.

Two useful answers

Can I connect a monitor or use it as a normal gaming graphics card?
No. The K40 has no HDMI, DisplayPort or other display connectors. It is a headless compute accelerator.

Does 12 GB mean all 12 GB is available with ECC on?
No. NVIDIA specifies that ECC reserves approximately 6.25% of the memory, leaving about 11.25 GB available when ECC is enabled.

My advice: match the software first, then confirm the server's airflow and power provisions. Browse Electronics & Gadgets, Tech Essentials and Deals & Price Drops for related finds.
