GeForce 7950 GT from Zogis
As you can see in Figure 4, the video card cooler does not touch the memory chips.
We removed the cooler to take a look, and as you can see in Figure 5 it is all made of copper.
In Figure 6 you have an overall look of the GeForce 7950 GT without its cooler.
This video card uses eight GDDR3 512-Mbit 1.4 ns chips from Infineon (HYB18H512321AF-14) as you can see in Figure 7, making the 512 MB of memory this video card has. Since these chips can run up to 1.4 GHz (700 MHz x 2) and on this video card the memory is already accessed at 1.4 GHz, there is no room left for overclocking the memories inside their specs. Of course you can try pushing them above their specs.
In Figure 8, you can see the GeForce 7950 GT chip (codenamed G71-GT2).
