Thermal pad for VRAM (Video Random Access Memory) can be necessary in some cases, depending on the specific graphics card and the cooling solution being used.

VRAM modules generate heat during operation, and if the heat is not dissipated effectively, it can lead to reduced performance, instability, or even damage to the graphics card. In some cases, the VRAM chips may not make good contact with the cooler or heat sink, which can result in hot spots that can damage the chip over time.

Thermal pad are often used as an thermal interface materials (TIMs) between the VRAM chips and the cooler or heat sink. They help to fill any gaps or uneven surfaces between the two, allowing for more efficient heat transfer and helping to prevent hot spots.

Whether thermal pad are necessary for VRAM will depend on the specific graphics card and cooling solution being used. In general, high-end graphics cards with more powerful GPUs and more VRAM are more likely to require thermal pad to ensure proper cooling. It's always a good idea to consult the thermal pad manufacturer ecommendations and guidelines for your specific graphics card to determine whether thermal pad are necessary and how they should be installed.
