PRODUCT PICTORIAL & WALKTHROUGH
Let's take a virtual walk around HIS's Reference version of ATI's HD5770.
First off we start at this videocard's VPU. HIS's use of the 40nm manufactured RV830 core is complimented with a stock clock of 700Mhz core and 1150Mhz DDR5 memory. It's memory subsystem is the main difference other than the core capabilities between it and the HD5870. The HD5870 is 256bit DDR5 and capable of 153.6Mb/sec of bandwidth whereas the HD5750 is 128bit DDR5 and only capable of 73.6Mb/sec which also is 3.2gb/s slower than the HD5770.
As mentioned earlier, HIS uses the ICeQ+ cooler for this particular card. Nothing more needs to be said other than overall, it's a solid cooler and no upgrading should be needed other than what I will mention in the upcoming photos.
The back of the card is simple and unobstructed so that it won't interfere with any motherboard northbridge cooling solutions. The only concern I have is that the main side of the videocard has its memory chips cooled directly by the IceQ+ cooler whereas on the back there is nothing. I am personally not a huge fan of this seeing it will lead to some overclocking issues while some of the chips are cool and stable and the others are under load and running at the hot DDR5 memory speeds. Even a couple memory heatsinks will make a huge difference.
The power supplied through the PCI Express slot alone will not power this videocard. You will have to use a 6 pin molex connector from your power supply or you can use the supplied adapter in the hardware kit. Also I need to note the coolers two cool air intakes. Make sure these are unobstructed by wires or cables during operating for proper cooling.
Last but not least in this section is the main connection panel. You have three choices which consist of a DVI, one DisplayPort and one HDMI video connection. There is also the videocard's exhaust vent which thankfully is full size and better than the vent supplied with the reference based HIS HD5770. Getting rid of the warm air shouldn't be a problem.
