 Card  ASUS Logo  Heatpipes  Fan The cooling solution on the card has to be mentioned. ASUS has a 29 fin fan on the rear of the front of the PCB. There is a funnel which air is blown through to the front grill when 2D mode is in operation. This is the standard cooling system found on many an ATI card since the HD 3870 card of 2007. On top of the card are two heatpipes that draw air upward when 3D mode is in operation. ATI says this is a Hybrid Cooling solution that provides the best of both worlds.  Default temperature  Load When the card was clocked at default speeds it ran great in 2D mode, with temperatures of around 36C under normal operations. In 3D mode after running 3DMark06 to stress the card, the card reached a maximum temperature with normal clock speeds of 42C, which is much cooler than ATI's reference card. Overclocking the card brought the temperature up to 63C but this is still a far cry from the high temperatures found on the card on the reference cooler.  Fan power  Capacitors  Top of heatpipe  Bottom of heatpipe There are 8 memory chips on the card. Each of the chips is a 512-bit chip, bringing a total of 512MB of GDDR3 memory. The memory is clocked at 1986MHz by default, meaning that there is about 64GB of memory bandwidth when considering the 256-bit memory bus. The rear of the card has the mounting bracket for the GPU, the Part Number sticker and the various circuitries necessary to run this card efficiently.  Rear of Card  Rear of PCB  PCI Express  IO ASUS decided to include the standard Dual Dual-Link DVI connectors and TV-Out connector combination that has been around for several years. The HD 4850 card supports HDMI and VGA Output, but these require adapters. Two monitors can be used with either two DVI, two HDMI, two VGA, one HDMI+DVI, one VGA+HDMI, one DVI+VGA combinations all supported. Note that ASUS includes a HDMI adapter and a VGA adapter in the bundle for excellent monitor support. Contents:
