Overview

Quadro4 900 XGL is an NVIDIA GPU entry in the Quadro4 family. It is listed with Kelvin architecture and NV25 silicon.

Key reference data: 128 MB DDR memory, 128-bit memory bus.

Workstation cards should be checked against driver branch, application certification, memory capacity, and display output requirements.

Why It Mattered

Quadro4 900 XGL represents the professional side of Quadro4 and the Kelvin generation around 2002. Certified-driver workflows, VRAM configuration, display outputs, and OEM workstation compatibility are the main historical reasons to track it separately from consumer GeForce models.

Collector Notes

For archival use, record the OEM or board-partner part number, bracket height, cooler type, memory configuration, display-output adapter or breakout cable, firmware, certified-driver branch, and the workstation model where the card was used.

Used-Market Caution

Before buying used, confirm bracket height, display adapters, mini-DP or DMS breakout cables, fan condition, VRAM errors, driver branch support, OEM firmware quirks, and whether the card needs workstation-specific airflow or auxiliary power.
