We disassembled the video card heatsink to take a look, see Figure 3. If you pay attention you will see that the heatsink part that touches the GPU is made of copper, which spreads heat better than aluminum. We were also curious to see if this big heatsink touched the memory chips or not.

The heatsink does touch the memory chips. This video card uses 2 ns GDDR3 memory chips from Infineon which can run up to 1 GHz, according to the manufacturer. Since this video card accesses the memory at 1 GHz, there is very little room for memory overclocking inside the memory’s specifications. But of course you can try overclock it over its specs.

This video card has two DVI connectors, allowing you to use two video monitors on your PC.
