The iCooler that HIS is using on the card isn't a new design and we've seen it before on lower end offerings. It tends to handle the GPU well and it will be interesting to see how we go when we overclock today.
Heading to the back of the card we've got a single 6-pin PCIe power connector. Normally we'd move across the top and towards the front where we'd be greeted with a CrossFire connector. Being a HD 7770, though, means that we don't have one.
Finishing up with the I/O side of things we've got a Dual-Link DVI connector on the right followed up with a HDMI and VGA port to round off connectivity.
With no Turbo labeling on the card the HIS HD 7770 iCooler 1GB carries with it the default clocks that you'll see on a reference clocked HD 7770. That means the core comes in at 1000MHz while the 1GB of GDDR5 comes in at 1125MHz or 4500MHz QDR.
As we mentioned earlier we're taking the time to overclock this video card today and looking above you can see we pushed the core up to 1120MHz. As for the 1GB of GDDR5 that got pushed to an even 5000MHz QDR.
