Introduction (Cont’d)

As you may already know, GeForce 9800 GTX+ is simply an overclocked GeForce 9800 GTX. On GeForce 9800 GTX the graphics chip runs at 675 MHz, while on GTX+ it runs at 738 MHz (a 9.33% overclocking). On both cards the memory runs at 1.1 GHz (2.2 GHz DDR) and is accessed through a 256-bit interface, achieving a maximum theoretical transfer rate of 70.4 GB/s.

Hydra system comes with two GeForce 9800 GTX+ to be connected under SLI configuration.

We removed the video card coldplate to take a look. As explained, this part is all made of copper.

On Figures 8 you can see the video card without its coldplate. It uses eight 512-Mbit Samsung K4J52324QE-BJ08 GDDR3 chips, making its 512 MB memory (512 Mbit x 8 = 512 MB). These chips can officially work up to 1.25 GHz (2.5 GHz DDR) and on this video card they are running at 1.1 GHz (2.2 GHz DDR), so there is 13% headroom for you to overclock the memories keeping them inside their specs. Of course you can always try to push them above their official specs.

This video card requires the installation of two auxiliary 6-pin power connectors, so in theory you need to have a power supply with four auxiliary cables for video cards. The product, however, comes with four adapters for you to convert standard peripheral power plugs into 6-pin power plugs, so if you power supply doesn’t have enough power plugs for video cards this won’t be an issue.

In Figure 8, you can see all accessories and CDs/DVDs that come with this video card. With the accessories that come with this card you can convert the video output to VGA and HDMI, plus the DVI and S-Video connectors already present on the product.

Hydra system comes with one full game, Tom Clancy’s Rainbowsix Vegas 2.
