Due to the use of water block, the card now takes only one slot, but it still has a dual slot backplate. The EK water block is made out of copper and has support for both 1/2" and 3/8" fittings. The card got a slight factory overclock as well and it works at 875MHz for the core and 5000MHz for 1GB of GDDR5 memory, which is 25MHz overclock for the core and 50MHz (200MHz effective) overclock for memory.
