Overview

GeForce GT 640 OEM Rebrand is an NVIDIA GPU entry in the GeForce 600 Series family. It is listed with Fermi 2.0 architecture and GF116 silicon.

Key reference data: 144 CUDA cores/shaders, 1.5 GB DDR3 memory, 192-bit memory bus, 75 W board power class.

Board-partner cards can vary in cooler, PCB, display outputs, clocks, BIOS behavior, and power connector layout.

Why It Mattered

GeForce GT 640 OEM Rebrand is an OEM-focused GeForce 600 Series variant from the Fermi 2.0 generation around 2012. These cards often differ from retail models in clocks, cooler, power limits, outputs, and firmware, which is why exact identification matters for upgrades, repairs, and used-system checks.

Collector Notes

For archival use, record the OEM system model, board part number, VBIOS, cooler, slot width, memory chips, power connectors, display outputs, bracket type, and any factory power or clock limits.

Used-Market Caution

Before buying used, confirm the card fits the target case and PSU, then check the exact OEM part number, bracket, power connector, outputs, VBIOS, thermal paste and fan condition, and whether retail drivers support the device ID cleanly.

Known Issues

Known issues pending source review.
