Identify the exact card and memory variant

The base T400 get 2 GB; the T400 wey dem mention separately, 4GB, get 4 GB.

Read the complete name on the card label or system inventory and match am to the manufacturer table. A similar numeric name no dey enough: desktop workstation cards, laptop GPUs and other vendors' products fit use overlapping numbers. No transfer the specifications of a 8 GB variant to a 4 GB board, or desktop board dimensions to a laptop implementation.

Memory capacity, bandwidth and practical workloads

This model get 2 GB of dedicated GDDR6 memory on a 64-bit interface. Capacity dey determine how much data fit reside for that memory; the rated bandwidth of up to 80 GB/s describe another limit. A bigger capacity alone no mean more shader resources or higher bandwidth.

For a CAD scene, image batch or compute workload, include textures, geometry, temporary buffers and application overhead when you dey estimate memory demand. A program wey pass local memory fit slow down or fail based on im own memory-management behavior. Compare the actual project and software version instead of using a memory-size label as a performance score.

Power, cooling and physical fit

NVIDIA dey list maximum card power of 30 W, active cooling and a single-slot board wey measure 2.713 inches high by 6.137 inches long. Maximum card power no be idle draw, a whole-PC measurement or a power-supply recommendation.

Check the exact workstation's supported graphics options, available slot and bracket, clearance around adjacent components and required airflow. A low-profile board still need the appropriate mounting bracket for im enclosure. A mechanically suitable PCIe slot no dey establish firmware, power or cooling compatibility by itself. Follow the system manufacturer's installation procedure.

Display connections and adapters

The reference card provide 3 Mini DisplayPort 1.4 connectors. Mini DisplayPort na connector type; e no mean say a full-size DisplayPort cable fit fit directly. The datasheet describe adapter support for VGA, DVI and HDMI, but the correct adapter depend on the required signal, resolution and refresh rate.

The manufacturer dey list 3 simultaneous 3840 x 2160 displays at 120 Hz or 3 simultaneous 5120 x 2880 displays at 60 Hz. These na stated configurations, no be promise for every combination of adapters, cables, color settings and monitors. Check the intended topology and each component's supported link mode.

Peak specifications and application support

The datasheet's up-to-1.09-TFLOPs single-precision figure na theoretical peak based on GPU Boost clock. E no be measured frame rate, rendering score or sustained application result. Workloads also depend on memory access, precision, CPU performance, drivers and application-specific implementation.

The Turing architecture name no establish the presence of every feature of a higher-tier RTX product. Verify the application's exact graphics/compute API, hardware feature level, CUDA runtime and driver requirements. A manufacturer certification claim for a product family no be proof say every version of a specific application and operating system dey certified for this card.

If the card dey detected but the application or display fail

Confirm the exact card identity and memory size, then install the system or GPU vendor's supported driver for the OS wey you dey run. Check say the monitor connect to the intended graphics device and say the selected input, cable and adapter support the requested mode. Test one display and a documented mode before you add a complex multi-monitor arrangement.

For application failures, preserve the error message and a small reproducible workload. Check the application's supported GPU/driver matrix and actual rendering or compute backend. Reduce project memory demand as a diagnostic when the application report an allocation failure. Avoid firmware changes, clock overrides or random driver packages as an initial response; use supported recovery procedures if a driver update need to be reversed.
