 The main advantage of HIS IceQ models is the design of their cooler, which blows hot air produced by the video card out the computer case – and later copied by Sapphire. Also, it is sensitive to UV light, so it will grow if you have an UV lamp inside your case. This cooler is entirely made of aluminum and it is actually made by Arctic Cooling (

The heatsink used on this video card doesn’t touch the memory chips.

Talking about memory, this video card uses eight GDDR2 256-Mbit 2.5 ns chips from Hynix (HY5PS561621AFP-25), making its 256 MB video memory (256 Mbits x 8 = 256 MB). These chips can run up to 800 MHz. Since this video card accesses the memory very close to 800 MHz there is no room for memory overclocking inside the memory’s specifications. But of course you can try overclock it over its specs.
