The GeForce GTS 450 (Cont’d)
In Figure 4, you can see the video card with its cooler removed. Note how it requires one six-pin auxiliary power connector. In Figures 5 and 6, you can see the cooler by itself. The cooler used on the GeForce GTS 450 is made of aluminum and cools down only the GPU.
The reviewed card uses eight 1 Gbit GDDR5 chips (four soldered on each side of the printed circuit board), making its 1 GB video memory (1 Gbit x 8 = 1 GB).
The chips used are K4G10325FE-HC05 parts from Samsung, which support up to 1 GHz (4 GHz QDR) and since on this video card memory is accessed at 902 MHz (3,608 MHz QDR), there is a good margin for you to increase the memory clock rate while keeping the chips inside the maximum they support. Of course you can always try to overclock the memory chips above their specs.
Before seeing the performance results, let’s recap the main features of this video card.
