In Figure 5, you can see the video card with its cooler removed. As you can see, it uses individual aluminum heatsinks with copper base on the GPUs and aluminum passive heatsinks on the memory chips. Also notice how this video card uses only solid aluminum capacitors, which are the best kind of electrolytic capacitor.

The reviewed video card has eight 1 Gbit GDDR3 memory chips from Samsung (K4J10324QD-HJ1A) around each GPU, making its 1 GB per GPU or 2 GB total. These chips support up to 1 GHz (2 GHz DDR), so there is no margin for you to overclock the memories with them still inside their specs. Of course you can try overclocking them above their labeled maximum clock rate.
