EVGA GeForce GTX 660 Ti SuperClocked Video Card Review

The EVGA GeForce GTX 660 Ti SuperClocked (Cont’d)

In Figure 6, you can see the video card with its cooler removed. We were impressed by how short the printed circuit board is, at 6.8” (172 mm). The video card, however, is a little longer, at 9.5” (240 mm), because of the fan.

It uses a voltage regulator with four phases for the GPU and two phases for the memory chips. The voltage regulator circuit uses a digital design and is controlled by an NCP5392P chip. All coils use ferrite cores and all capacitors are solid.

The reviewed video card uses eight Hynix H5GQ2H24AFR-R0C GDDR5 chips, each one storing 2 Gbit of data, comprising the 2 GB of memory available on this video card. Six of these chips are located on the component side of the printed circuit board, each connected to the GPU through a 32-bit lane, creating the 192-bit datapath that is available. The other two chips are located on the solder side of the printed circuit board and apparently share the datapaths used by two of the chips that are available on the component side of the board. There are spaces for soldering four additional memory chips, so the 3 GB version of this video card most likely uses the same printed circuit board but has all of the spaces populated.

The chips that come soldered on this video card can run up to 6 GHz. On this video card, they are ac
cessed at 6,008 MHz.
