The Card


Pulling the card out of the box, it's refreshing to see that Palit have opted to use a new style of cooler. While the reference cooler does a good job of keeping the card at a bearable temperature, it's always nice to see something a bit different.

The Palit uses a dual-fan design that helps cool the giant heatsink which has three heat pipes coming out of the top. The card actually uses two different sized fans; the left one that sits closer to the core is slightly larger than the one that sits towards the back of the card.

Looking around the card, apart from the cooler there isn't really anything out of the ordinary; we have two 6-pin PCI Express connectors at the back of the card while across the top we have our two Crossfire connectors.

The I/O panel manages to hold some surprises; apart from the standard two Dual-Link DVI connectors, we also have a display port connector.

Towards the bottom right of the I/O bracket we have a switch that lets you overclock the card. There are two modes; normal and turbo. You can switch between default and overclock specifications when your computer is off.




While you might think normal is default, it's not. Normal refers to the standard Sonic clocks which give us the default core speed of 750MHz, but an overclocked memory clock of 950MHz or 3800MHz Data Rate, which is up from the 900MHz or 3600MHz Data Rate of the reference clocks.


If you want to up the ante, though, and quite honestly who doesn't? Switching to turbo will boost the core to 775MHz and the memory clock to 1000MHz or 4000MHz Data Rate. These clocks are mighty impressive and should give quite a boost in some of our tests. Let's find out.
