The Gigabyte HD 2400 XT is a low profile card that has a very large heatsink instead of a cooling fan. Gigabyte chose the blue colored PCB, which adds to it's pleasant looking design. This video card uses the power from the X16 PCI Express slot, so there is no need for an external power connection to run it. The connections on this card include a D-Sub/VGA, an S-Video port and a DVI port for high definition video and HDCP support.
Like I mentioned above, the Gigabyte HD 2400 XT uses a unique cooling method called "Screen Cooling". This takes a fan-less heatsink and extends it past the width of the PCB, making the card essentially a full size ATX card. This gives the video card a wider and thicker look, while effectively cooling it with zero noise level, from the lack of fans. This design also protects the VGA connection, which uses a ribbon cable to extend the port on the PCI bracket, from snagging or damage. By removing the outer connection bracket we can get a better look at the fins of the heatsink and the holes which allow air flow from the case to pass through them and cool the card.
After removing the heatsink, we are able to get a look at all of the cards glory. The HD 2400 XT uses the RV610 core, which is one of the first GPUs to be manufactured using a 65nm process, for higher clock speeds while running at cooler temps. The stock clock speed of the GPU is 700MHZ and pushes video to a resolution of 2560 x 1600 via dual 400MHZ RAMDACs. The memory on the HD 2400 XT is 256MB DDR2, manufactured by Hynix and runs at 400MHz (800MHz effective) on a 64-bit memory interface.
Now that we have taken a good look at the card itself, let's install the software to get the magic happening.
