HIS 7770 iCooler Detailed Features
In this section we shall take an in depth look at the HIS HD 7770 iCooler video card and see what makes it tick.
With the fan and shroud removed we can get a better look at the aluminum heatsink. There isn't really much to it but as you will see later in the article it performs very well indeed.
With the cooler assembly fully removed we can get a better look at the board, The overall layout of all the components is a little different than what we are used to on high end video cards. The compact layout has moved the power phase/VRM section to the left of the PCB. Advances in nano-scale manufacturing technologies mean that 1GB of memory can be squeezed into a much smaller package, here we have only four memory modules whereas only last year or so 1GB video cards would have needed eight. All in all the PCB looks good with no real waste of space and the soldering quality is of a very high standard
The back of the PCB is utilised mainly for resistors and the soldering quality is excellent for such tiny components. Man loses the war to the machine when it comes to detailed work like this. These days you don't generally see RAM on the reverse side of a 1GB video card design thanks to the smaller manufacturing process that allows more density in a smaller package.
The HIS HD 7770 iCooler uses 1GB of hynix H5GQ2H24MFR-TC2 memory divided between four modules, rated at 2.5GHz (5GHz effective) at 1.5V.
In the next section we will look at the main features and specifications of the HIS HD 7770 iCooler 1GB video card.
