PRODUCT PICTORIAL & WALKTHROUGH
Last but not least in this section is the main connection panel. You have three choices which consist of one DVI, one analog, and an HDMI connection. There is no VIVO capabilities with this card. In addition you also have the rear exhaust port which exhaust only a portion of the videocards heat. The rest is pushed out around the rest of the cooler and into the case. I would have liked to have seen more ventilation holes in the heatsink's plastic cover to allow for better exhaust flow but the air going into the case will also cool the heatsinks attached to the card's voltage regulators.
With the stock values of 850Mhz core and 993Mhz memory set, I allowed ATI's auto-tune to push the card to its 100% stable ceiling. Through an hour of testing and benchmarking, it was able to find a 100% stable overclock of 990Mhz core and 1100Mhz memory. When I state a stable overclock, I mean an overclock that works and never freezes or presents artifacts during any game or benchmark.
To any overclocker with a stock card with a decent cooler, a 115Mhz core and a 107Mhz memory overclock is pretty decent. I have seen this memory overclock 50Mhz higher on other cards, but the core going up an additional 115Mhz is pretty spectacular. The cooler does its job very well.
Even when the overclock was in place, the cooler fan only ramped up 10-15% and the VPU temperature never went above 55c.
